<h2 id="summary">Summary</h2>
|
||||
<p>This article describes how to install iRedMail (iRedMail-0.8.6 or later
|
||||
releases) with a remote MySQL server, and you must choose MySQL backend in
|
||||
iRedMail installation wizard.</p>
|
||||
<p>We use below server IP addresses in our example:</p>
|
||||
<ul>
|
||||
<li><code>192.168.1.100</code>: Remote MySQL server.</li>
|
||||
<li><code>192.168.1.200</code>: iRedMail server. We're going to install the latest iRedMail
|
||||
on this server.</li>
|
||||
</ul>
|
||||
<p>iRedMail won't install MySQL server (RPM/DEB package) on localhost with remote
|
||||
MySQL server, but MySQL client tools are still required for remote connection.</p>
|
||||
<h2 id="requirements">Requirements</h2>
|
||||
<p>In our case, remote MySQL server runs on server <code>192.168.1.100</code>. It must accept
|
||||
remote connection from iRedMail server <strong>BEFORE</strong> installing iRedMail, and we
|
||||
must create a new SQL user with password and proper privileges for remote login
|
||||
from iRedMail server (<code>192.168.1.200</code> in our case).</p>
|
||||
<ul>
|
||||
<li>Make sure your remote MySQL server accepts remote connection from iRedMail
|
||||
server. For example, you can check it with command <code>netstat</code>:</li>
|
||||
</ul>
|
||||
<pre><code># netstat -ntlp | grep 3306
|
||||
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 2479/mysqld
|
||||
</code></pre>
|
||||
|
||||
<p>If MySQL server is listening on only 127.0.0.1, you should comment out
|
||||
<code>bind-address</code> parameter in MySQL config file <code>my.cnf</code> to make it listen on all
|
||||
available network interfaces, and restart MySQL service.</p>
|
||||
<ul>
|
||||
<li>On Red Hat Enterprise Linux, CentOS, openSUSE, OpenBSD, it's <code>/etc/my.cnf</code>.</li>
|
||||
<li>On Debian, Ubuntu, it's <code>/etc/mysql/my.cnf</code>.</li>
|
||||
<li>On FreeBSD, it's <code>/var/db/mysql/my.cnf</code>.</li>
|
||||
</ul>
|
||||
<pre><code>#bind-address = 127.0.0.1
|
||||
</code></pre>
|
||||
|
||||
<ul>
|
||||
<li>
|
||||
<p>Make sure remote MySQL request will not be blocked by network firewall like
|
||||
iptables (Linux), ipfw (FreeBSD) or PF (OpenBSD).</p>
|
||||
</li>
|
||||
<li>
|
||||
<p>Create a new SQL user (<code>admin_iredmail</code>) with new password (<code>admin_password</code>)
|
||||
and all privileges on remote MySQL server (of course you must choose another
|
||||
strong password):</p>
|
||||
</li>
|
||||
</ul>
|
||||
<pre><code>mysql> GRANT ALL PRIVILEGES ON *.* TO 'admin_iredmail'@'192.168.1.200' IDENTIFIED BY 'admin_password' WITH GRANT OPTION;
|
||||
mysql> FLUSH PRIVILEGES;
|
||||
mysql> FLUSH HOSTS;
|
||||
</code></pre>
|
||||
|
||||
<p>With above commands, MySQL user <code>admin_iredmail</code> is allowed to connect from IP
|
||||
address <code>192.168.1.200</code> with password <code>admin_password</code>.</p>
|
||||
<p><strong>Notes</strong>:</p>
|
||||
<ul>
|
||||
<li><code>WITH GRANT OPTION</code> in above SQL command is required.</li>
|
||||
<li>Of course you can use <code>root</code> or other MySQL user as remote MySQL user name
|
||||
in above SQL command, but a custom user name should be better to help you
|
||||
understand what it's used for, and less confuse with default <code>root</code> user.</li>
|
||||
<li>You must replace <code>192.168.1.200</code> by the real IP address of your iRedMail
|
||||
server in above command.</li>
|
||||
<li>It's recommended to delete this user AFTER iRedMail installation, it won't
|
||||
be used anymore. We will give you SQL command to delete it later.</li>
|
||||
</ul>
|
||||
<p>If you tried to install iRedMail with this remote MySQL server before, please
|
||||
drop existing databases and MySQL users which will be created by iRedMail on
|
||||
remote MySQL server:</p>
|
||||
<pre><code>mysql> DROP DATABASE amavisd;
|
||||
mysql> DROP DATABASE cluebringer;
|
||||
mysql> DROP DATABASE iredadmin;
|
||||
mysql> DROP DATABASE roundcubemail;

|
||||
|

# Install iRedMail with a remote MySQL server
|
||||
|
||||
[TOC]
|
||||
|
||||
## Summary
|
||||
|
||||
This article describes how to install iRedMail (iRedMail-0.8.6 or later
|
||||
releases) with a remote MySQL server, and you must choose MySQL backend in
|
||||
iRedMail installation wizard.
|
||||
|
||||
We use below server IP addresses in our example:
|
||||
|
||||
* `192.168.1.100`: Remote MySQL server.
|
||||
* `192.168.1.200`: iRedMail server. We're going to install the latest iRedMail
|
||||
on this server.
|
||||
|
||||
iRedMail won't install MySQL server (RPM/DEB package) on localhost with remote
|
||||
MySQL server, but MySQL client tools are still required for remote connection.
|
||||
|
||||
## Requirements
|
||||
|
||||
In our case, remote MySQL server runs on server `192.168.1.100`. It must accept
|
||||
remote connection from iRedMail server __BEFORE__ installing iRedMail, and we
|
||||
must create a new SQL user with password and proper privileges for remote login
|
||||
from iRedMail server (`192.168.1.200` in our case).
|
||||
|
||||
* Make sure your remote MySQL server accepts remote connection from iRedMail
|
||||
server. For example, you can check it with command `netstat`:
|
||||
|
||||
```
|
||||
# netstat -ntlp | grep 3306
|
||||
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 2479/mysqld
|
||||
```
|
||||
|
||||
If MySQL server is listening on only 127.0.0.1, you should comment out
|
||||
`bind-address` parameter in MySQL config file `my.cnf` to make it listen on all
|
||||
available network interfaces, and restart MySQL service.
|
||||
|
||||
* On Red Hat Enterprise Linux, CentOS, openSUSE, OpenBSD, it's `/etc/my.cnf`.
|
||||
* On Debian, Ubuntu, it's `/etc/mysql/my.cnf`.
|
||||
* On FreeBSD, it's `/var/db/mysql/my.cnf`.
|
||||
|
||||
```
|
||||
#bind-address = 127.0.0.1
|
||||
```
|
||||
|
||||
* Make sure remote MySQL request will not be blocked by network firewall like
|
||||
iptables (Linux), ipfw (FreeBSD) or PF (OpenBSD).
|
||||
|
||||
* Create a new SQL user (`admin_iredmail`) with new password (`admin_password`)
|
||||
and all privileges on remote MySQL server (of course you must choose another
|
||||
strong password):
|
||||
|
||||
```
|
||||
mysql> GRANT ALL PRIVILEGES ON *.* TO 'admin_iredmail'@'192.168.1.200' IDENTIFIED BY 'admin_password' WITH GRANT OPTION;
|
||||
mysql> FLUSH PRIVILEGES;
|
||||
mysql> FLUSH HOSTS;
|
||||
```
|
||||
|
||||
With above commands, MySQL user `admin_iredmail` is allowed to connect from IP
|
||||
address `192.168.1.200` with password `admin_password`.
|
||||
|
||||
__Notes__:
|
||||
|
||||
* `WITH GRANT OPTION` in above SQL command is required.
|
||||
* Of course you can use `root` or other MySQL user as remote MySQL user name
|
||||
in above SQL command, but a custom user name should be better to help you
|
||||
understand what it's used for, and less confuse with default `root` user.
|
||||
* You must replace `192.168.1.200` by the real IP address of your iRedMail
|
||||
server in above command.
|
||||
* It's recommended to delete this user AFTER iRedMail installation, it won't
|
||||
be used anymore. We will give you SQL command to delete it later.
|
||||
|
||||
If you tried to install iRedMail with this remote MySQL server before, please
|
||||
drop existing databases and MySQL users which will be created by iRedMail on
|
||||
remote MySQL server:
|
||||
|
||||
```
|
||||
mysql> DROP DATABASE amavisd;
|
||||
mysql> DROP DATABASE cluebringer;
|
||||
mysql> DROP DATABASE iredadmin;
|
||||
mysql> DROP DATABASE roundcubemail;
|
||||
mysql> DROP DATABASE vmail;
|
||||
|
||||
mysql> DROP USER 'amavisd'@'192.168.1.200';
|
||||
mysql> DROP USER 'cluebringer'@'192.168.1.200';
|
||||
mysql> DROP USER 'iredadmin'@'192.168.1.200';
|
||||
mysql> DROP USER 'roundcube'@'192.168.1.200';
|
||||
mysql> DROP USER 'vmail'@'192.168.1.200';
|
||||
mysql> DROP USER 'vmailadmin'@'192.168.1.200';
|
||||
```
|
||||
|
||||
## Install iRedMail
|
||||
|
||||
Please follow iRedMail installation guide strictly, but start iRedMail
|
||||
installer with below command instead of the original one (`bash iRedMail.sh`):
|
||||
|
||||
```
|
||||
# MYSQL_SERVER='192.168.1.100' MYSQL_ROOT_USER='admin_iredmail' MYSQL_GRANT_HOST='192.168.1.200' bash iRedMail.sh
|
||||
```
|
||||
|
||||
It will launch iRedMail installation wizard as usual. When it asks MySQL root
|
||||
password, please input the password (`admin_password` in our case) we created
|
||||
on remote MySQL server.
|
||||
|
||||
Parameters we used in above command line:
|
||||
|
||||
* `MYSQL_SERVER`: Remote MySQL server address.
|
||||
* `MYSQL_ROOT_USER`: MySQL user name we created on remote MySQL server before installing iRedMail.
|
||||
* `MYSQL_GRANT_HOST`: Hostname or IP address of iRedMail server.
|
||||
|
||||
iRedMail will create new SQL users for applications like Postfix, Amavisd,
|
||||
Roundcube webmail, etc, and grant proper privileges to them which will connect
|
||||
from iRedMail server.
|
||||
|
||||
One more optional parameter is `MYSQL_SERVER_PORT`. it specifies listen port
|
||||
of remote MySQL server. Default one is `3306`, you can change it if remote
|
||||
MySQL server is running on a different port.
|
||||
|
||||
## After iRedMail installation
|
||||
|
||||
As mentioned above, it's now ok to delete the new MySQL user `admin_iredmail`
|
||||
on remote MySQL server. It will not be used anymore.
|
||||
|
||||
```
|
||||
mysql> DROP USER 'admin_iredmail'@'192.168.1.200';
|
||||
```
