# Scripted Upgrade

VCL 2.4.2 is the first release to include an upgrade script. All you need to
upgrade VCL is the script. It will download and validate the VCL software and
then upgrade your system. The script can be used to upgrade all three parts of
VCL (database, web portal, and management node) or to upgrade each part
individually. It works for upgrading from any previous version of Apache VCL.

[Download Upgrade Script (vcl-upgrade.sh)](https://www.apache.org/dist/vcl/2.4.2/vcl-upgrade.sh)

    :::BashLexer
    wget https://www.apache.org/dist/vcl/2.4.2/vcl-upgrade.sh.sha1
    sha1sum -c vcl-upgrade.sh.sha1
    wget https://www.apache.org/dist/vcl/KEYS
    gpg --import KEYS
    wget https://www.apache.org/dist/vcl/2.4.2/vcl-upgrade.sh.asc
    gpg --verify vcl-upgrade.sh.asc

Running the upgrade script with no arguments will step you through upgrading
all three parts of VCL. Alternatively, the following explains optional 
arguments. If upgrading the management node part of VCL, it will also prompt 
you to agree to the installation of various system level requirements needed 
for the code to run.

    :::BashLexer
    vcl-upgrade.sh [-h|--help] [-d|--database] [-w|--web] [-m|--managementnode]
            [--dbhost <hostname>] [--dbadminuser <username>]
            [--dbadminpass <password>]

    -d|--database - upgrade database components
            --dbhost may optionally be specified if not localhost

    -w|--web - upgrade web server components

    -m|--managementnode - upgrade management node (vcld) components

    --dbhost <hostname> - hostname of database server (default=localhost)

    --dbname <name> - name of VCL database on database server (default=vcl)

    --dbadminuser <username> - admin username for database; must have access
            to modify database schema and dump data for backup (default=root)

    --dbadminpass <password> - password for dbadminuser (default=[no password])

# Manual Upgrade Instructions

These instructions explain how to upgrade from VCL 2.3.2 to VCL 2.4.2. Please note 
it only applies for the upgrade from 2.3.2 to 2.4.2, this may or may not work for other 
versions.

**The basic steps that will be performed**

  - Download and Extract 2.4.2 code 
  - Shutdown httpd and vcld services
  - Create backup of vcl database 
  - Update mysql schema
  - Update web code, create a backup, copy in new, make changes 
  - Restart httpd service
  - Update management node vcl code, create a backup, copy in new, make changes 
  - Restart vcld service

### Upgrade steps

1. follow instructions on the [VCL download](http://vcl.apache.org/downloads/download.cgi) 
page to download and verify apache-VCL-2.4.2.tar.bz2 and put in in /root
2. **extract VCL 2.4.2 code**
    
        :::BashLexer
        tar xf apache-VCL-2.4.2.tar.bz2

3. **Shutdown** the httpd and vcld services
           
        :::BashLexer
        service httpd stop
        service vcld stop

4. create a **backup** of the VCL database. This will provide a restore point if 
necessary.

        :::BashLexer
        mysqldump vcl > ~/vcl-pre2.4.2-upgrade.sql

5. This step **updates the database** schema.

        :::BashLexer
        mysql vcl < /root/apache-VCL-2.4.2/mysql/update-vcl.sql

6. **Update the web code**. This step we will move the 2.3.2 web directory out of the 
way, so we can copy in the new web code base. After copying in the new code, we will 
migrate your configuration changes. These instructions assume that you installed the 
VCL web code at /var/www/html/vcl. If you installed it elsewhere, replace 
/var/www/html/vcl with your vcl web root.

        :::BashLexer
        mv /var/www/html/vcl /var/www/html/vcl-2.3.2

7. **Disable access** to the old web code

        :::BashLexer
        echo "Deny from all" > /var/www/html/vcl-2.3.2/.htaccess

7. **Copy the new code** in place
	
        :::BashLexer
        cp -r /root/apache-VCL-2.4.2/web /var/www/html/vcl-2.4.2
        ln -s /var/www/html/vcl-2.4.2 /var/www/html/vcl

8. **Copy your 2.3.2 config files**
	
        :::BashLexer
        cd /var/www/html/vcl-2.3.2/.ht-inc
        cp conf.php secrets.php pubkey.pem keys.pem /var/www/html/vcl/.ht-inc

9. **Add new items to conf.php**. The following items need to be added to the conf.php
file (they can be added anywhere as long as it is not inside an 
array() definition):

        :::BashLexer
        (don't forget to edit conf.php in the **new** location)
        vim /var/www/html/vcl/.ht-inc/conf.php
<br>

        :::PhpLexer
        define("SEMTIMEOUT", "45");

        define("MAXINITIALIMAGINGTIME", 720); // for imaging reservations, users will have at least this long as the max selectable duration

        define("MAXSUBIMAGES", 5000);  // maximum allowed number for subimages in a config

        # boolean value of 0 or 1 to enable documentation links on login page and page
        #   where authentication method is selected
        # 0 = disables; 1 = enabled
        define("NOAUTH_HOMENAV", 0);

        # boolean value of 0 or 1 to control logging of non SELECT database queries for auditing or debugging purposes; queries are logged to the querylog table
        define("QUERYLOGGING", 1);

        # boolean value of 0 or 1 to control logging of XMLRPC calls for auditing or debugging purposes; queries are logged to the xmlrpcLog table
        define("XMLRPCLOGGING", 1);

        # documentation links to display on login page and page
        #   where authentication method is selected when NOAUTH_HOMENAV is set to 1
        $NOAUTH_HOMENAV = array (
            "What is VCL" => "http://vcl.apache.org/",
            "How to use VCL" => "https://cwiki.apache.org/confluence/display/VCL/Using+VCL",
            "Report a Problem" => "mailto:" . HELPEMAIL,
        );

9. **Make the maintenance directory writable** by the web server user. Normally this is
the apache user, if using a different user change below cmd accordingly.
	
        :::BashLexer
        chown apache /var/www/html/vcl/.ht-inc/maintenance

11. **Start httpd service**

        :::BashLexer
        service httpd start

12. **Backup management node code**. This step will make a backup copy of the 2.3.2  
management node code. These instructions assume that you installed the 
VCL management node code at /usr/local/vcl. If you installed it elsewhere, replace 
/usr/local with your management node path.
	
        :::BashLexer
        cp -r /usr/local/vcl /usr/local/vcl-2.3.2

13. **Copy in the 2.4.2 management node code** to /usr/local. First, rename the existing
management node code directory to vcl-2.4.2 so that any drivers or other files you've 
added are preserved. Then, create a symlink for /usr/local/vcl and copy the new 
management code over top of it.
	
        :::BashLexer
        mv /usr/local/vcl /usr/local/vcl-2.4.2
        ln -s /usr/local/vcl-2.4.2 /usr/local/vcl
        /bin/cp -r /root/apache-VCL-2.4.2/managementnode/* /usr/local/vcl

14. **Run install_perl_libs.pl** to add any new perl library requirements:
	
        :::BashLexer
        /usr/local/vcl/bin/install_perl_libs.pl

15. **Start vcld service**
	
        :::BashLexer
        service vcld start

16. Make some **test reservations** and watch the vcld.log to verify everything is working 
correctly.

        :::BashLexer
        tail -f /var/log/vcld.log
