Use the qjail utility to deploy small or large numbers of jails quickly.
|
|
|
|
First issue "rehash" command to enable the qjail command (if using csh).
|
|
Then issue "man qjail-intro" to read the qjail introduction.
|
|
After reading that do "man qjail" for the usage details.
|
|
For the BIG PICTURE issue "man qjail-howto".
|

|
For users who have existing qjail environments. Please take note.
|
|
There are changes to the internals of the jail(8) command and changes to
|
|
parameter names in the periodic files that have occured in FreeBSD
|
|
Release 10.2 that effects jail behavior in a very minor way.
|
|
IF your running qjail on an 10.2 or newer version of FreeBSD you should
|
|
consider doing the following.
|
|
|
|
This version of qjail has an built in auto convert function that you may select
|
|
to choose that fixes those minor behavior problems with your existing jails.
|
|
This auto convert function is not documented in the qjail manual. Its only
|
|
shown here. So write it down.
|
|
|
|
Issue [ qjail update -u ] from the host console.
|
|
|
|
This will cause the existing "flavors" default & ssh-default directories to be
|
|
renamed and new ones populated. Then in each existing jail the periodic.conf
|
|
and newsyslog.conf files will be renamed with .saved suffix and new ones added.
|
|
The rc.conf file will be updated in place changing the
|
|
syslogd_enable= parameter value from "NO" to "YES".
|
|
|
|
The new periodic.conf file has many sendmail reporting options disabled because
|
|
sendmail is disabled in the jails rc.conf file by default. This drastically
|
|
reduces the daily. weekly, monthly system and security status reports elapse
|
|
run times. This has a major effect on operating system performance where there
|
|
are a large number of jails.
|
|
|
|
The [ qjail install ] command will install all the correct files depending on
|
|
what version of FreeBSD your host is running.
