How To Setup FreeBSD Jails With ezjail

To set up FreeBSD jails using ezjail, you can follow these steps:

1. Install the ezjail package using the pkg command. For example:

pkg install ezjail

This will install the ezjail package and all of its dependencies.

2. Edit the /usr/local/etc/ezjail.conf file and set the ezjail_use_zfs option to yes. This will enable ZFS support for the jails.

3. Create a ZFS dataset for the jail root file system. For example:

zfs create -o mountpoint=/jails zroot/jails

This will create a ZFS dataset for the jail root file system and mount it at /jails.

4. Create a base jail using the ezjail-admin command. For example:

ezjail-admin create -s 30M basejail 192.168.0.100

This will create a base jail with the specified IP address and a 30MB slice size.

5. Create a new jail using the ezjail-admin command. For example:

ezjail-admin create -r /jails/basejail newjail 192.168.0.101

This will create a new jail using the basejail as a template and assign it the specified IP address.

6. Start the jail using the ezjail-admin command. For example:

ezjail-admin start newjail

This will start the newjail jail.

It's important to note that you may need to have root privileges to install packages and use the ezjail-admin command.

For more information about setting up FreeBSD jails using ezjail, you can refer to the ezjail documentation or use the --help option with the ezjail-admin command. For example:

man ezjail-admin

ezjail-admin --help

It's also important to note that you may need to configure the network settings and enable the network interface for the jails to work properly. You can do this by adding the following lines to the /etc/rc.conf file:

ifconfig_em0="inet 192.168.0.100 netmask 255.255.255.0"
defaultrouter="192.168.0.1"

This will configure the em0 interface with the specified IP address and default router.
