System requirements

• Install the latest iRedMail and DBMail by following this tutorial: Integrate DBMail in iRedMail (MySQL backend)

    • MySQLdb. A thread-compatible interface to the popular MySQL database server that provides the Python database API.

Add new system account: iredadmin

We will make iRedAdmin run with Apache web server, but as non-apache, low privilege user: iredadmin.

# useradd -s /sbin/nologin -m -d /home/iredadmin iredadmin

Install necessary packages

• Make sure you have iRedMail yum repository configured: /etc/yum.repos.d/iRedMail.repo.

[iRedMail]
name=iRedMail
baseurl=http://iredmail.org/yum/rpms/5/
enabled=1
gpgcheck=0
priority=1

Note: If you're running RHEL/CentOS/Scientific Linux 6.x, please replace 5 by 6 in baseurl=.

• Install necessary packages.

# ---- For i386 ----
# yum install python-webpy python-jinja2 MySQL-python mod_wsgi

# ---- For x86_64 ----
# yum install MySQL-python.x86_64 python-webpy.noarch python-jinja2.x86_64 mod_wsgi.x86_64

Download iRedAdmin and configure Apache web server

• Get iRedAdmin:
  • If you purchased iRedAdmin-Pro-MySQL, you should already have it. If not, please mail to support@ iredmail.org to get a download link.
  • If you didn't purchase iRedAdmin-Pro-MySQL, download iRedAdmin open source edition from download page.

• Copy iRedAdmin to /var/www/, set correct file permissions, and create symbol link.

# tar xjf iRedAdmin-x.y.z.tar.bz2 -C /var/www/
# cd /var/www/
# chown -R iredadmin:iredadmin iRedAdmin-x.y.z
# chmod -R 0755 iRedAdmin-x.y.z
# ln -s iRedAdmin-x.y.z iredadmin

• Add apache configure file: /etc/httpd/conf.d/iredadmin.conf.

#
# Note: Uncomment below two lines if you want to make iRedAdmin accessable via HTTP.
#
#WSGIScriptAlias /iredadmin /var/www/iredadmin/iredadmin.py/
#Alias /iredadmin/static /var/www/iredadmin/static/

WSGISocketPrefix /var/run/wsgi
WSGIDaemonProcess iredadmin user=iredadmin threads=15
WSGIProcessGroup iredadmin

AddType text/html .py

<Directory /var/www/iredadmin/>
    Order deny,allow
    Allow from all
</Directory>

• Edit /etc/httpd/conf.d/ssl.conf, make iredadmin accessable via HTTPS. Add below lines before </VirtualHost>:

WSGIScriptAlias /iredadmin /var/www/iredadmin/iredadmin.py/
Alias /iredadmin/static /var/www/iredadmin/static/

• Restart apache to enable mod_wsgi:

# /etc/init.d/httpd restart

Create necessary MySQL database and grant privileges

• Create MySQL database: iredadmin. Used to store sessions, admin operation logs, etc.

# mysql -uroot -p
mysql> CREATE DATABASE iredadmin DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
mysql> USE iredadmin;
mysql> SOURCE /var/www/iredadmin/docs/samples/iredadmin.sql;

• Grant privileges to iredadmin user and set password for it.

WARNING: Here we use 'secret_passwd' as password of iredadmin user, please replace it with your own password.

# mysql -uroot -p
mysql> GRANT SELECT,INSERT,UPDATE,DELETE ON iredadmin.* TO iredadmin@localhost IDENTIFIED BY 'secret_passwd';
mysql> FLUSH PRIVILEGES;

• Create addition columns for DBMail database: dbmail.

# mysql -uroot -p
mysql> USE dbmail;
mysql> SOURCE /var/www/iredadmin/docs/samples/dbmail_additions.mysql;

Note: It will create some addition MySQL tables, and add extra columns for existing dbmail tables.

Configure iRedAdmin

• Copy example config file, and set correct file permission.

# cd /var/www/iredadmin/
# cp settings.ini.mysql.sample settings.ini
# chown iredadmin:iredadmin settings.ini
# chmod 0600 settings.ini

• Edit settings.ini and set several variables.
  • NOTE: Please open settings.ini for more detail, it's self-documented.

[general]
# General settings ...

[iredadmin]
# Database "iredadmin". required by iRedAdmin.

[dbmail]
# Database "dbmail", stored all mail accounts and mail messages.

[policyd]
# Database "policyd".
# Required for policyd integration.

[amavisd]
# Database "amavisd".

• Restart apache web server.

# /etc/init.d/httpd restart

• Open your web browser to access iRedAdmin: https://your_server_ip_address/iredadmin/
  • NOTE: Make sure you use HTTPS:// instead of HTTP://.

Troubleshooting

If iRedAdmin doesn't work as expected, you can set debug = True in settings.ini to turn on debug mode, restart apache web server, use your favourite web browser to access it again, create a new forum topic and paste error message in forum topic.
