Summary

This tutorial describes how to create a FreeBSD Jail with ezjail, and install the latest iRedMail in Jail.

Notes:

This tutorial was tested with FreeBSD 9 and the latest ports tree, but it should work on FreeBSD 8 and 10 too.
All backends available in iRedMail (OpenLDAP, MySQL, PostgreSQL) were tested, work like a charm. :)

Requirements

iRedMail-0.8.3 or later releases.
Port sysutils/ezjail for FreeBSD.

Preparation

Prepare IP address used for Jail. Here we use internal IP address 172.16.122.244 for example. We created an alias IP address on network interface em0, so we have below setting in /etc/rc.conf for this IP address:

File: /etc/rc.conf

ifconfig_em0_alias0="inet 172.16.122.244 netmask 255.255.255.0"

Create Jail and install iRedMail

Install ezjail:

Terminal:

# cd /usr/ports/sysutils/ezjail/
# make install clean

Add below setting in /etc/rc.conf:

File: /etc/rc.conf

# Start ezjail while system start up
ezjail_enable="YES"

# Set security.jail.allow_raw_sockets=1 to allow PostgreSQL initial database.
jail_sysvipc_allow="YES"

Rebooting system is required after changing /etc/rc.conf.

Terminal:

# reboot

After system start up, create the base jail that all jails we created later will use:

Terminal:

# ezjail-admin install -p

create Jail for domain name mx.example.com, bound to internal IP address 172.16.122.244. All files are placed under /jails/mx.example.com:

Terminal:

# ezjail-admin create -r /jails/mx.example.com mx.example.com 172.16.122.244

Set hostname of Jail in /jails/mx.example.com/etc/rc.conf:

File: /jails/mx.example.com/etc/rc.conf

hostname="mx.example.com"

Start Jail.

Terminal:

# /usr/local/etc/rc.d/ezjail restart

List all Jails:

Terminal:

# ezjail-admin list
STA JID  IP               Hostname                          Root Directory
--- ---- ---------------- --------------------------------- ------------------------
DS  1    172.16.122.244   mx.example.com                    /jails/mx.example.com

We can now enter this Jail:

Terminal:

# ezjail-admin console mx.example.com

In Jail, update /etc/resolv.conf with valid DNS server address(es). For example:

File: Jail: /etc/resolv.conf

nameserver 172.16.122.2

In Jail, install binary package bash. Required by iRedMail.

Terminal:

Jail # pkg_add -r bash-static

In Jail, Start iRedMail installer with your Jail ip address:

Terminal:

Jail # bash
bash # cd /root/iRedMail/
bash # LOCAL_ADDRESS='172.16.122.244' bash iRedMail.sh

That's all.
