Creation of sample zone in Solaris for hosting apache, part 1

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

•     status of zones

bash-3.00# zoneadm list -v
 ID NAME             STATUS         PATH
  0 global           running        /

•     boot our new zone

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

•     check service

# telnet 192.168.30.100 80

So our apache is running and working :-)
