<h2>System Requirements<a class="headerlink" href="#system-requirements" title="Permalink to this headline"></a></h2>
<p>The user must have the following for a successful minimal install:</p>
<ul class="simple">
<li>CentOS 7</li>
<li>2 VMs with at least 2 vCPUs, 4GB RAM, 20 GB disk space each</li>
<li>Access to Centos Base and epel repositories</li>
<li>Access to <a class="reference external" href="http://www.cpan.org/">The Comprehensive Perl Archive Network (CPAN)</a></li>
</ul>
<p>As of version 2.0 only Postgres is supported as the database. This documentation assumes CentOS 7.2 and Postgresql 9.6.3 for a production install.</p>

<div class="section" id="navigating-the-install">
<h2>Navigating the Install<a class="headerlink" href="#navigating-the-install" title="Permalink to this headline"></a></h2>
<p>To begin the install:</p>
<ol class="arabic simple">
<li>Install Postgres</li>
</ol>
<blockquote>
<div><p>For a production install it is best to install postgres on it’s own server/VM. To install postgres, on the postgres host (pg)</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>pg-$ sudo su -
pg-# yum -y update
pg-# yum -y install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm
pg-# yum -y install postgresql96-server
pg-$ su - postgres
pg-$ /usr/pgsql-9.6/bin/initdb -A md5 -W #-W forces the user to provide a superuser (postgres) password
</pre></div>
</div>
<p>Edit <code class="docutils literal notranslate"><span class="pre">/var/lib/pgsql/9.6/data/pg_hba.conf</span></code> to allow your traffic ops app server access. For example if you are going to install traffic ops on <code class="docutils literal notranslate"><span class="pre">99.33.99.1</span></code> add:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>host all all 99.33.99.1/32 md5
</pre></div>
</div>
<p>to the appropriate section of this file. Edit the <code class="docutils literal notranslate"><span class="pre">/var/lib/pgsql/9.6/data/postgresql.conf</span></code> file to add the approriate listen_addresses or <code class="docutils literal notranslate"><span class="pre">listen_addresses</span> <span class="pre">=</span> <span class="pre">'*'</span></code>, set <code class="docutils literal notranslate"><span class="pre">timezone</span> <span class="pre">=</span> <span class="pre">'UTC'</span></code>, and start the database:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>pg-$ exit
pg-# systemctl enable postgresql-9.6
pg-# systemctl start postgresql-9.6
pg-# systemctl status postgresql-9.6
</pre></div>

<ol class="arabic" start="2">
<li><p class="first">Build Traffic Ops</p>
<p>Build a Traffic Ops rpm using the instructions under the <a class="reference internal" href="../../development/building.html#dev-building"><span class="std std-ref">Building Traffic Control</span></a> page.</p>

<li><p class="first">Install Postgresql</p>

</pre></div>
</div>
</li>
</ol>
<blockquote>
<div><p>Install some additional packages that it depends on that were not installed as dependecies in the previous step (these are for the 2.0.0 install, this may change, but the pre-installs won’t hurt):</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>to-# yum -y install git
to-# wget -q https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz

to-# PATH=$PATH:/usr/local/go/bin # go bins are needed in the path for postinstall
to-# go get bitbucket.org/liamstask/goose/cmd/goose
</pre></div>
</div>
<p>At this point you should be able to login to the database from the <code class="docutils literal notranslate"><span class="pre">to</span></code> host to the <code class="docutils literal notranslate"><span class="pre">pg</span></code> host like:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>to-# psql -h 99.33.99.1 -U postgres
Password for user postgres:
psql (9.6.3)
Type &quot;help&quot; for help.
postgres=#
</pre></div>
</div>
<p>Use this connectivity to create the user and database. In this example, we use user: <code class="docutils literal notranslate"><span class="pre">traffic_ops</span></code>, password: <code class="docutils literal notranslate"><span class="pre">tcr0cks</span></code>, database: <code class="docutils literal notranslate"><span class="pre">traffic_ops</span></code>:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>to-# psql -U postgres -h 99.33.99.1 -c &quot;CREATE USER traffic_ops WITH ENCRYPTED PASSWORD &#39;tcr0cks&#39;;&quot;
Password for user postgres:
CREATE ROLE
to-# createdb traffic_ops --owner traffic_ops -U postgres -h 99.33.99.1
Password:
to-#
</pre></div>
</div>
<p>Now, run the following command as root: <code class="docutils literal notranslate"><span class="pre">/opt/traffic_ops/install/bin/postinstall</span></code></p>
<p>The postinstall will first get all packages needed from CPAN. This may take a while, expect up to 30 minutes on the first install.
If there are any prompts in this phase, please just answer with the defaults (some CPAN installs can prompt for install questions).</p>
<p>When this phase is complete, you will see:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>Complete! Modules were installed into /opt/traffic_ops/app/local
</pre></div>
</div>
<p>Some additional files will be installed, and then it will proceed with the next phase of the install, where it will ask you about the local environment for your CDN. Please make sure you remember all your answers and the database answers match the database information previously used to create the database.</p>
