|
|
<p>iRedMail will store configrations in file iRedMail-x.y.z/config during
|
|
installation, and ask you whether to use it for installation directly
|
|
or create a new one.</p>
|
|
<p>You can create a sample config file by executing iRedMail installer:</p>
|
|
<pre><code class="bash"># bash iRedMail.sh
|
|
</code></pre>
|
|
|
|
<p>After config wizard dialogs, you will find file <code>config</code> under iRedMail root
|
|
directory. For example, <code>/root/iRedMail-0.8.7/config</code>. it will ask whether to
|
|
start installation or not, you can cancel it if you want.</p>
|
|
<p>You can copy this config file to deploy as many servers as you want, change
|
|
the hard-coded passwords in it if you want.</p>
|
|
<p>How to deploy a new server with sample config file:</p>
|
|
<ul>
|
|
<li>Copy sample config file to new server, e.g. <code>/root/iRedMail-0.8.7/config</code>.</li>
|
|
<li>Execute iRedMail installer with shell variables:</li>
|
|
</ul>
|
|

|
|

<h2 id="sample-deployment">Sample Deployment</h2>
|
|
<p>Here's how i preform iRedMail tests every day with VMware Fusion on Mac OS X,
|
|
all are completed automatically with a shell command.</p>
|
|
<ul>
|
|
<li>
|
|
<p>Install a clean, basic/minimal OS (Debian/CentOS/OpenBSD/FreeBSD, etc), set
|
|
proper hostname, configure network, then shut down this server and create a
|
|
VMware snapshot named <code>Latest</code>. The snapshot name will be used in my shell
|
|
script, it needs a snapshot name to reverse VM to the clean OS.</p>
|
|
</li>
|
|
<li>
|
|
<p>Revert VM to the latest snapshot (a clean, basic, minimal OS) with VMware
|
|
command line tool <code>vmrun</code>.</p>
|
|
</li>
|
|
<li>
|
|
<p>Start this VM with <code>vmrun</code>, sleep 30 (or 60) seconds waiting for OS start up.</p>
|
|
</li>
|
|
<li>
|
|
<p>Detect network connection to this VM, if it's up, upload required files with <code>scp</code>:</p>
|
|
</li>
|
|
<li>the latest development edition of iRedMail</li>
|
|
<li>source tarballs required by iRedMail (Roundcube, iRedAdmin, iRedAPD, etc)</li>
|
|
<li>
|
|
<p>downloaded RHEL/CentOS/Debian/Ubuntu/OpenBSD binary packages, FreeBSD
|
|
distfiles etc. The most important one is a prepared iRedMail config file: iRedMail-x.y.z/config.</p>
|
|
</li>
|
|
<li>
|
|
<p>Create/Update iRedMail installation status file: iRedMail-x.y.z/.status
|
|
to skip downloading source tarballs, etc.</p>
|
|
</li>
|
|
<li>
|
|
<p>Perform installation via ssh like this:</p>
|
|
</li>
|
|
</ul>
|
|
<pre><code class="shell">ssh root@[SERVER] "cd /root/iRedMail/ && IREDMAIL_DEBUG='NO' AUTO_USE_EXISTING_CONFIG_FILE=y AUTO_INSTALL_WITHOUT_CONFIRM=y AUTO_CLEANUP_REMOVE_SENDMAIL=y AUTO_CLEANUP_REMOVE_MOD_PYTHON=y AUTO_CLEANUP_REPLACE_FIREWALL_RULES=y AUTO_CLEANUP_RESTART_IPTABLES=y AUTO_CLEANUP_REPLACE_MYSQL_CONFIG=y AUTO_CLEANUP_RESTART_POSTFIX=n bash iRedMail.sh"
|
|
</code></pre>
|
|
|
|
<ul>
|
|
<li>Perform after-installation tasks: upload downloaded ClamAV database, ..., reboot server.</li>
|
|
</ul>
|
|
<p>It should complete in 2-3 minutes (uploading binary packages takes most time),
|
|
then i got a working iRedMail server. I do this many times every day.</p>
|
|
<p>I have 5 prepared iRedMail config files for different backends: OpenLDAP,
|
|
MySQL, MariaDB, PostgreSQL, ldapd (OpenBSD only). i run my script with an
|
|
option to install iRedMail with specified backend like below, the script will
|
|
upload proper config file to server:</p>
|
|
<pre><code class="shell"># bash auto.centos7.sh ldap
|
|
# bash auto.centos7.sh mysql
|
|
# bash auto.centos7.sh pgsql
|
|
# bash auto.ubuntu14.sh mariadb
|
|
# bash auto.openbsd55.sh ldapd
|
|
</code></pre>
|
|
|
|
<p>Below is file of <code>auto.centos7.sh</code> mentioned above, it prepares VMware virtual
|
|
machine, then execute another script <code>c7.sh</code> to perform the real installation.</p>
|
|
<pre><code class="shell">#!/usr/bin/env bash
|
|
