| <h2><a name="cust" id="cust">Customizing Apache for Windows</a></h2> |
| |
| |
| <p>Apache is configured by the files in the <code>conf</code> |
| subdirectory. These are the same files used to configure the Unix |
| version, but there are a few different directives for Apache on |
| Windows. See the <a href="../mod/directives.html">directive index</a> |
| for all the available directives.</p> |
| |
| <p>The main differences in Apache for Windows are:</p> |
| <ul> |
| <li><p>Because Apache for Windows is multithreaded, it does not |
| use a separate process for each request, as Apache can on Unix. |
| Instead there are usually only two Apache processes running: a |
| parent process, and a child which handles the requests. Within |
| the child process each request is handled by a separate thread. |
| </p> |
| |
| <p>The process management directives are also different:</p> |
| |
| <p><code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code>: |
| Like the Unix directive, this controls how many connections a single |
| child process will serve before exiting. |
| However, unlike on Unix, a replacement process is not instantly |
| available. Use the default <code>MaxConnectionsPerChild 0</code>, |
| unless instructed to change the behavior to overcome a memory leak |
| in third party modules or in-process applications.</p> |
| |
| <div class="warning"><strong>Warning: The server configuration |
| file is reread when a new child process is started. If you have |
| modified <code>httpd.conf</code>, the new child may not start or |
| you may receive unexpected results.</strong></div> |
| |
| <p><code class="directive"><a href="../mod/mpm_common.html#threadsperchild">ThreadsPerChild</a></code>: |
| This directive is new. It tells the server how many threads it |
| should use. This is the maximum number of connections the server |
| can handle at once, so be sure to set this number high enough for |
| your site if you get a lot of hits. The recommended default is |
| <code>ThreadsPerChild 150</code>, but this must be adjusted to |
| reflect the greatest anticipated number of simultaneous |
| connections to accept.</p></li> |
| |
| <li><p>The directives that accept filenames as arguments must use |
| Windows filenames instead of Unix ones. However, because Apache |
| may interpret backslashes as an "escape character" sequence, you |
| should consistently use forward slashes in path names, not |
| backslashes.</p></li> |
| |
| <li><p>While filenames are generally case-insensitive on |
| Windows, URLs are still treated internally as case-sensitive |
| before they are mapped to the filesystem. For example, the |
| <code class="directive"><a href="../mod/core.html#location"><Location></a></code>, |
| <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>, and <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> directives all use |
| case-sensitive arguments. For this reason, it is particularly |
| important to use the <code class="directive"><a href="../mod/core.html#directory"><Directory></a></code> directive when attempting |
| to limit access to content in the filesystem, since this |
| directive applies to any content in a directory, regardless of |
| how it is accessed. If you wish to assure that only lowercase |
| is used in URLs, you can use something like:</p> |
| |
| <pre class="prettyprint lang-config">RewriteEngine On |
| RewriteMap lowercase int:tolower |
| RewriteCond "%{REQUEST_URI}" "[A-Z]" |
| RewriteRule "(.*)" "${lowercase:$1}" [R,L]</pre> |
| </li> |
| |
| <li><p>When running, Apache needs write access only to the logs |
| directory and any configured cache directory tree. Due to the |
| issue of case insensitive and short 8.3 format names, Apache must |
| validate all path names given. This means that each directory |
| which Apache evaluates, from the drive root up to the directory |
| leaf, must have read, list and traverse directory permissions. |
| If Apache2.4 is installed at C:\Program Files, then the root |
| directory, Program Files and Apache2.4 must all be visible |
| to Apache.</p></li> |
| |
| <li><p>Apache for Windows contains the ability to load modules at |
| runtime, without recompiling the server. If Apache is compiled |
| normally, it will install a number of optional modules in the |
| <code>\Apache2.4\modules</code> directory. To activate these or |
| other modules, the <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> |
| directive must be used. For example, to activate the status |
| module, use the following (in addition to the status-activating |
| directives in <code>access.conf</code>):</p> |
| |
| <pre class="prettyprint lang-config">LoadModule status_module "modules/mod_status.so"</pre> |
| |
| |
| <p>Information on <a href="../mod/mod_so.html#creating">creating |
| loadable modules</a> is also available.</p></li> |
| |
| <li><p>Apache can also load ISAPI (Internet Server Application |
| Programming Interface) extensions such as those used by Microsoft |
| IIS and other Windows servers. <a href="../mod/mod_isapi.html">More |
| information is available</a>. Note that Apache <strong>cannot</strong> |
| load ISAPI Filters, and ISAPI Handlers with some Microsoft feature |
| extensions will not work.</p></li> |
| |
| <li><p>When running CGI scripts, the method Apache uses to find |
| the interpreter for the script is configurable using the |
| <code class="directive"><a href="../mod/core.html#scriptinterpretersource">ScriptInterpreterSource</a></code> |
| directive.</p></li> |
| |
| <li><p>Since it is often difficult to manage files with names |
| like <code>.htaccess</code> in Windows, you may find it useful to |
| change the name of this per-directory configuration file using |
| the <code class="directive"><a href="../mod/core.html#accessfilename">AccessFilename</a></code> |
| directive.</p></li> |
| |
| <li><p>Any errors during Apache startup are logged into the |
| Windows event log when running on Windows NT. This mechanism |
| acts as a backup for those situations where Apache is not yet |
| prepared to use the <code>error.log</code> file. You can |
| review the Windows Application Event Log by using the Event Viewer, |
| e.g. Start - Settings - Control Panel - Administrative Tools |
| - Event Viewer.</p></li> |

| <h2><a name="winsvc" id="winsvc">Running Apache as a Service</a></h2> |
| |
| |
| <p>Apache comes with a utility called the Apache Service Monitor. |
| With it you can see and manage the state of all installed Apache |
| services on any machine on your network. To be able to manage an |
| Apache service with the monitor, you have to first install the |
| service (either automatically via the installation or manually). |
| </p> |
| |
| <p>You can install Apache as a Windows NT service as follows from |
| the command prompt at the Apache <code>bin</code> subdirectory:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k install |
| </code></p></div> |
| |
| <p>If you need to specify the name of the service you want to |
| install, use the following command. You have to do this if you |
| have several different service installations of Apache on your |
| computer. If you specify a name during the install, you have to |
| also specify it during any other -k operation.</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k install -n "MyServiceName" |
| </code></p></div> |
| |
| <p>If you need to have specifically named configuration files for |
| different services, you must use this:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k install -n "MyServiceName" -f "c:\files\my.conf" |
| </code></p></div> |
| |
| <p>If you use the first command without any special parameters except |
| <code>-k install</code>, the service will be called <code>Apache2.4</code> |
| and the configuration will be assumed to be <code>conf\httpd.conf</code>. |
| </p> |
| |
| <p>Removing an Apache service is easy. Just use:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k uninstall |
| </code></p></div> |
| |
| <p>The specific Apache service to be uninstalled can be specified by using:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k uninstall -n "MyServiceName" |
| </code></p></div> |
| |
| <p>Normal starting, restarting and shutting down of an Apache |
| service is usually done via the Apache Service Monitor, by using |
| commands like <code>NET START Apache2.4</code> and <code>NET STOP |
| Apache2.4</code> or via normal Windows service management. Before |
| starting Apache as a service by any means, you should test the |
| service's configuration file by using:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -n "MyServiceName" -t |
| </code></p></div> |
| |
| <p>You can control an Apache service by its command line switches, |
| too. To start an installed Apache service you'll use this:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k start -n "MyServiceName" |
| </code></p></div> |
| |
| <p>To stop an Apache service via the command line switches, use |
| this:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k stop -n "MyServiceName" |
| </code></p></div> |
| |
| <p>or</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k shutdown -n "MyServiceName" |
| </code></p></div> |
| |
| <p>You can also restart a running service and force it to reread |
| its configuration file by using:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k restart -n "MyServiceName" |
| </code></p></div> |
| |
| <p>By default, all Apache services are registered to run as the |
| system user (the <code>LocalSystem</code> account). The |
| <code>LocalSystem</code> account has no privileges to your network |
| via any Windows-secured mechanism, including the file system, named |
| pipes, DCOM, or secure RPC. It has, however, wide privileges locally. |
| </p> |
| |
| <div class="warning"><strong>Never grant any network privileges to |
| the <code>LocalSystem</code> account! If you need Apache to be able |
| to access network resources, create a separate account for Apache as |
| noted below.</strong></div> |
| |
| <p>It is recommended that users create a separate account for running |
| Apache service(s). If you have to access network resources via Apache, |
| this is required.</p> |
| |
| <ol> |
| <li>Create a normal domain user account, and be sure to |
| memorize its password.</li> |
| |
| <li>Grant the newly-created user a privilege of <code>Log on |
| as a service</code> and <code>Act as part of the operating |
| system</code>. On Windows NT 4.0 these privileges are granted via |
| User Manager for Domains, but on Windows 2000 and XP you probably |
| want to use Group Policy for propagating these settings. You can |
| also manually set these via the Local Security Policy MMC snap-in. |
| </li> |
| |
| <li>Confirm that the created account is a member of the Users |
| group.</li> |
| |
| <li>Grant the account read and execute (RX) rights to all document |
| and script folders (<code>htdocs</code> and <code>cgi-bin</code> |
| for example).</li> |
| |
| <li>Grant the account change (RWXD) rights to the |
| Apache <code>logs</code> directory.</li> |
| |
| <li>Grant the account read and execute (RX) rights to the |
| <code>httpd.exe</code> binary executable.</li> |
| </ol> |
| |
| <div class="note">It is usually a good practice to grant the user the Apache |
| service runs as read and execute (RX) access to the whole Apache2.4 |
| directory, except the <code>logs</code> subdirectory, where the |
| user has to have at least change (RWXD) rights.</div> |
| |
| <p>If you allow the account to log in as a user and as a service, |
| then you can log on with that account and test that the account has |
| the privileges to execute the scripts, read the web pages, and that |
| you can start Apache in a console window. If this works, and you |
| have followed the steps above, Apache should execute as a service |
| with no problems.</p> |
| |
| <div class="note"><strong>Error code 2186</strong> is a good indication that |
| you need to review the "Log On As" configuration for the service, |
| since Apache cannot access a required network resource. Also, pay |
| close attention to the privileges of the user Apache is |
| configured to run as.</div> |
| |
| <p>When starting Apache as a service you may encounter an error |
| message from the Windows Service Control Manager. For example, |
| if you try to start Apache by using the Services applet in the |
| Windows Control Panel, you may get the following message:</p> |
| |
| <div class="example"><p><code> |
| Could not start the Apache2.4 service on \\COMPUTER <br /> |
| Error 1067; The process terminated unexpectedly. |
| </code></p></div> |
| |
| <p>You will get this generic error if there is any problem with |
| starting the Apache service. In order to see what is really causing |
| the problem you should follow the instructions for Running Apache |
| for Windows from the Command Prompt.</p> |
| |
| <p>If you are having problems with the service, it is suggested |
| you follow the instructions below to try starting httpd.exe from |
| a console window, and work out the errors before struggling to |
| start it as a service again.</p> |
| </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> |
| <div class="section"> |
| <h2><a name="wincons" id="wincons">Running Apache as a Console Application</a></h2> |
| |
| |
| <p>Running Apache as a service is usually the recommended way to |
| use it, but it is sometimes easier to work from the command line, |
| especially during initial configuration and testing.</p> |
| |
| <p>To run Apache from the command line as a console application, |
| use the following command:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe |
| </code></p></div> |
| |
| <p>Apache will execute, and will remain running until it is stopped |
| by pressing Control-C.</p> |
| |
| <p>You can also run Apache via the shortcut Start Apache in Console |
| placed to <code>Start Menu --> Programs --> Apache HTTP Server |
| 2.4.xx --> Control Apache Server</code> during the installation. |
| This will open a console window and start Apache inside it. If you |
| don't have Apache installed as a service, the window will remain |
| visible until you stop Apache by pressing Control-C in the console |
| window where Apache is running in. The server will exit in a few |
| seconds. However, if you do have Apache installed as a service, the |
| shortcut starts the service. If the Apache service is running |
| already, the shortcut doesn't do anything.</p> |
| |
| <p>If Apache is running as a service, you can tell it to stop by opening another console |
| window and entering:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k shutdown |
| </code></p></div> |
| |
| <p>Running as a service should be preferred over running in a |
| console window because this lets Apache end any current operations |
| and clean up gracefully.</p> |
| |
| <p>But if the server is running in a console window, you can |
| only stop it by pressing Control-C in the same window.</p> |
| |
| <p>You can also tell Apache to restart. This forces it to reread |
| the configuration file. Any operations in progress are allowed to |
| complete without interruption. To restart Apache, either press |
| Control-Break in the console window you used for starting Apache, |
| or enter</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -k restart |
| </code></p></div> |
| |
| <p>if the server is running as a service.</p> |
| |
| <div class="note">Note for people familiar with the Unix version of Apache: |
| these commands provide a Windows equivalent to <code>kill -TERM |
| <em>pid</em></code> and <code>kill -USR1 <em>pid</em></code>. The |
| command line option used, <code>-k</code>, was chosen as a reminder |
| of the <code>kill</code> command used on Unix.</div> |
| |
| <p>If the Apache console window closes immediately or unexpectedly |
| after startup, open the Command Prompt from the Start Menu --> |
| Programs. Change to the folder to which you installed Apache, type |
| the command <code>httpd.exe</code>, and read the error message. Then |
| change to the logs folder, and review the <code>error.log</code> |
| file for configuration mistakes. Assuming httpd was installed into |
| <code>C:\Program Files\Apache Software Foundation\Apache2.4\</code>, |
| you can do the following:</p> |
| |
| <div class="example"><p><code> |
| c: <br /> |
| cd "\Program Files\Apache Software Foundation\Apache2.4\bin" <br /> |
| httpd.exe |
| </code></p></div> |
| |
| <p>Then wait for Apache to stop, or press Control-C. Then enter the |
| following:</p> |
| |
| <div class="example"><p><code> |
| cd ..\logs <br /> |
| more < error.log |
| </code></p></div> |
| |
| <p>When working with Apache it is important to know how it will |
| find the configuration file. You can specify a configuration file |
| on the command line in two ways:</p> |
| |
| <ul> |
| <li><p><code>-f</code> specifies an absolute or relative path to |
| a particular configuration file:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -f "c:\my server files\anotherconfig.conf" |
| </code></p></div> |
| |
| <p>or</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -f files\anotherconfig.conf |
| </code></p></div></li> |
| |
| <li><p><code>-n</code> specifies the installed Apache service |
| whose configuration file is to be used:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -n "MyServiceName" |
| </code></p></div> |
| </li> |
| </ul> |
| |
| <p>In both of these cases, the proper |
| <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> should be set in |
| the configuration file.</p> |
| |
| <p>If you don't specify a configuration file with <code>-f</code> |
| or <code>-n</code>, Apache will use the file name compiled into the |
| server, such as <code>conf\httpd.conf</code>. This built-in path |
| is relative to the installation directory. You can verify the compiled |
| file name from a value labelled as <code>SERVER_CONFIG_FILE</code> when |
| invoking Apache with the <code>-V</code> switch, like this:</p> |
| |
| <div class="example"><p><code> |
| httpd.exe -V |
| </code></p></div> |
| |
| <p>Apache will then try to determine its <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> by trying the following, in this order:</p> |
| |
| <ol> |
| <li>A <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> directive |
| via the <code>-C</code> command line switch.</li> |
| |
| <li>The <code>-d</code> switch on the command line.</li> |
| |
| <li>Current working directory.</li> |
| |
| <li>A registry entry which was created if you did a binary |
| installation.</li> |
| |
| <li>The server root compiled into the server. This is <code> |
| /apache</code> by default, you can verify it by using <code> |
| httpd.exe -V</code> and looking for a value labelled as |
| <code>HTTPD_ROOT</code>.</li> |
| </ol> |
| |
| <p>If you did not do a binary install, Apache will in some |
| scenarios complain about the missing registry key. This warning can |
| be ignored if the server was otherwise able to find its |
| configuration file.</p> |
| |
| <p>The value of this key is the |
| <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> directory which |
| contains the <code>conf</code> subdirectory. When Apache starts it |
| reads the <code>httpd.conf</code> file from that directory. If |
| this file contains a <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> |
| directive which contains a different directory from the one |
| obtained from the registry key above, Apache will forget the |
| registry key and use the directory from the configuration file. If |
| you copy the Apache directory or configuration files to a new |
| location it is vital that you update the |
| <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> directive in the |
| <code>httpd.conf</code> file to reflect the new location.</p> |

| <h2><a name="test" id="test">Testing the Installation</a></h2> |
| |
| |
| <p>After starting Apache (either in a console window or as a |
| service) it will be listening on port 80 (unless you changed the |
| <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> directive in the |
| configuration files or installed Apache only for the current user). |
| To connect to the server and access the default page, launch a |
| browser and enter this URL:</p> |
| |
| <div class="example"><p><code> |
| http://localhost/ |
| </code></p></div> |
| |
| <p>Apache should respond with a welcome page and you should see |
| "It Works!". If nothing happens or you get an error, look in the |
| <code>error.log</code> file in the <code>logs</code> subdirectory. |
| If your host is not connected to the net, or if you have serious |
| problems with your DNS (Domain Name Service) configuration, you |
| may have to use this URL:</p> |
| |
| <div class="example"><p><code> |
| http://127.0.0.1/ |
| </code></p></div> |
| |
| <p>If you happen to be running Apache on an alternate port, you |
| need to explicitly put that in the URL:</p> |
| |
| <div class="example"><p><code> |
| http://127.0.0.1:8080/ |
| </code></p></div> |
| |
| <p>Once your basic installation is working, you should configure it |
| properly by editing the files in the <code>conf</code> subdirectory. |
| Again, if you change the configuration of the Windows NT service |
| for Apache, first attempt to start it from the command line to |
| make sure that the service starts with no errors.</p> |
| |
| <p>Because Apache <strong>cannot</strong> share the same port with |
| another TCP/IP application, you may need to stop, uninstall or reconfigure |
| certain other services before running Apache. These conflicting |
| services include other WWW servers, some firewall implementations, |
| and even some client applications (such as Skype) which will use port |
| 80 to attempt to bypass firewall issues.</p> |

| <h2><a name="windrivemap" id="windrivemap">Configuring Access to Network Resources</a></h2> |
| |
| |
| <p>Access to files over the network can be specified using two |
| mechanisms provided by Windows:</p> |
| |
| <dl> |
| <dt>Mapped drive letters</dt> |
| <dd>e.g., <code>Alias "/images/" "Z:/"</code></dd> |
| |
| <dt>UNC paths</dt> |
| <dd>e.g., <code>Alias "/images/" "//imagehost/www/images/"</code></dd> |
| </dl> |
| |
| <p>Mapped drive letters allow the administrator to maintain the |
| mapping to a specific machine and path outside of the Apache httpd |
| configuration. However, these mappings are associated only with |
| interactive sessions and are not directly available to Apache httpd |
| when it is started as a service. <strong>Use only UNC paths for |
| network resources in httpd.conf</strong> so that the resources can |
| be accessed consistently regardless of how Apache httpd is started. |
| (Arcane and error prone procedures may work around the restriction |
| on mapped drive letters, but this is not recommended.)</p> |
| |
| <div class="example"><h3>Example DocumentRoot with UNC path</h3><pre class="prettyprint lang-config">DocumentRoot "//dochost/www/html/"</pre> |
| </div> |
| |
| <div class="example"><h3>Example DocumentRoot with IP address in UNC path</h3><pre class="prettyprint lang-config">DocumentRoot "//192.168.1.50/docs/"</pre> |
| </div> |
| |
| <div class="example"><h3>Example Alias and corresponding Directory with UNC path</h3><pre class="prettyprint lang-config">Alias "/images/" "//imagehost/www/images/" |
| |
| <Directory "//imagehost/www/images/"> |
| #... |
| </Directory></pre> |
| </div> |
| |
| <p>When running Apache httpd as a service, you must create a |
| separate account in order to access network resources, as described |
| above.</p> |
