- Let's use ZFS for storage of zones to help better disk management
zpool create -f zones c0d1
zfs create zones/apache
mount
/zones on zones read/write/setuid/devices/exec/atime/dev.......
/zones/apache on zones/apache read/write/setuid/devices/exec/atime/dev.......
- Change the mode of directory because of need of zone management software
bash-3.00# chmod 700 /zones/apache
- Create zone, named apache
bash-3.00# zonecfg -z apache
apache: No such zone configured
Use 'create' to begin configuring a new zone.
- * we start with initial creation of zone
zonecfg:apache> create
- * set the path where zone will reside
zonecfg:apache> set zonepath=/zones/apache
- * set autoboot flag to boot when server boot
zonecfg:apache> set autoboot=true
- * add network IP and physical interface. Do not forget to set netmask
zonecfg:apache> add net
zonecfg:apache:net> set address=192.168.30.100/24
zonecfg:apache:net> set physical=pcn0
zonecfg:apache:net> end
- * add external directory /opt to be part of zone (just in case)
zonecfg:apache> add inherit-pkg-dir
zonecfg:apache:inherit-pkg-dir> set dir=/opt
zonecfg:apache:inherit-pkg-dir> end
- * get the config info about the zone (on screen)
zonecfg:apache> info
zonepath: /zones/apache
autoboot: true
pool:
inherit-pkg-dir:
dir: /lib
inherit-pkg-dir:
dir: /platform
inherit-pkg-dir:
dir: /sbin
inherit-pkg-dir:
dir: /usr
inherit-pkg-dir:
dir: /opt
net:
address: 192.168.30.100/24
physical: pcn0
- * commit all the changes we made
zonecfg:apache> commit
- * export the config for future usage or just for backup. Do not put it in /tmp, because on each boot this filesystem is purged
zonecfg:apache> export -f /zones/apache-zone.cfg
- * and exit from the program
zonecfg:apache> exit
- Now let's install the software in zone (this operation will take a while)
bash-3.00# zoneadm -z apache install
Preparing to install zone <apache>.
Creating list of files to copy from the global zone.
Copying <2361> files to the zone.
Initializing zone product registry.
Determining zone package initialization order.
Preparing to initialize <968> packages on the zone.
Initializing package <372> of <968>: percent complete: 38%......
- Little check of situation
- * diskspace
bash-3.00# df -k /zones/apache/
Filesystem kbytes used avail capacity Mounted on
zones/apache 12321792 70034 12251635 1% /zones/apache
bash-3.00# zoneadm list -v
ID NAME STATUS PATH
0 global running /
bash-3.00# zoneadm -z apache boot
- * and check again zones status
bash-3.00# zoneadm list -v
ID NAME STATUS PATH
0 global running /
2 apache running /zones/apache
- Some preparation tasks
- * login in to the zone
bash-3.00# zlogin apache
[Connected to zone 'apache' pts/2]
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
- * create some directories where we will place web server
(we aware directories /lib, /opt, /platform, /sbin and /usr are mounted
from global zone as readonly, but / (root) not so we put there our
apache)
# mkdir -p /www/src
- * copy the software (from other terminal :-)
bash-3.00# cd /zones/apache/root/www/src/
bash-3.00# cp /tmp/httpd-2.2.4.tar.gz .
- * decompress and untar the archive (from with in zone)
# cd /www/src
# gzip -d httpd-2.2.4.tar.gz|tar
# tar xvf httpd-2.2.4.tar
- * configure and compile the software (its take a while)
# cd httpd-2.2.4
# ./configure --prefix=/www --enable-so –enable-mods-shared=all
<cut long listing>
# make
<cut long listing>
# make test
`test' is up to date.
# make install
<cut long listing>
- * create user to manage files
# groupadd w3
# useradd -g w3 w3
# chown -R w3:w3 /www/htdocs
- * edit /www/conf/httpd.conf to change User and Group from daemon to w3
- * edit /etc/hosts to add line like this
192.168.30.100 apache.example.net apache
- let's run the http server
# /www/bin/apachectl start
- check if the server is running
- * check process
# ps -efl|grep htt

- So our apache is running and working :-)
- for next example let's create another zone, named apache2,
but this time we will use apache server from Solaris and config file
from previous zone
# cp /zones/apache-zone.cfg /zones/apache2-zone.cfg
- edit file and change zonepath and IP address
- next will use this config file to initialize new zone
# zonecfg -z apache2 -f /zones/apache2-zone.cfg
# zoneadm -z apache2 install
# zoneadm -z apache2 boot
- add own users w3 with group w3 and create and edit config
file. Do not forget to change IP address apache will listen and
/etc/hosts for FQDN of host
# cp /etc/apache2/httpd.conf-example /etc/apache2/httpd.conf
# groupadd w3
# useradd -g w3 w3
- create directory /var/run/apache2, because it do not exist,
but it's need to keep apache pid file or make some changes in apache
config file
mkdir -p /var/run/apache2
- start server and test if it's work
# /usr/apache2/bin/apachectl start
# ps -efl|grep http

- and now we have 2 zones and 2 different web servers
