Creating a datacenter in one Solaris machine

There is a big event coming: Cebit!

And with that I took the task to implement a demo for MySQL Enterprise Monitor to show at the Sun booth. So I need a machine for the enterprise monitor and some machines to run MySQL databases. After all I need something to monitor.

So the setup will be an Ultra 24 desktop machine installed with OpenSolaris 2008.11 . For every machine I will install a zone to run a separate database and one zone to run the enterprise monitor.

So here is my first round of experiences: Installing a template container on OpenSolaris and cloning it to build four or five separate database machines. Let's go:

root@ap-mysql:/# zfs create -o mountpoint=/zones rpool/zones

# Create a template zone, that will be cloned for all demo zones

Use 'create' to begin configuring a new zone.

# Now we have the TEMPLATE zone. Next step is to install the zone and boot it.
# CAVEAT: The machine needs internet access to install a zone. The software respository must be www.opensolaris.org in the moment... :-(

root@ap-mysql:/# zoneadm -z TEMPLATE install
A ZFS file system has been created for this zone.
Authority: Using http://pkg.opensolaris.org/release/.

PHASE ITEMS
Reading Existing Index 9/9

Note: Man pages can be obtained by installing SUNWman
Postinstall: Copying SMF seed repository ... done.

Next Steps: Boot the zone, then log into the zone console
(zlogin -C) to complete the configuration process

# time to boot the zone
# prepare a second terminal window and start the zone's console with
# zlogin -C TEMPLATE
####################################################################################

root@ap-mysql:~# zoneadm -z TEMPLATE boot

####################################################################################
# In TEMPLATE's console, do the interactive sysidcfg procedure
# I like to install some other packages. The default set is too small for me
# Adding packages is easy: 'pkg install SUNWxyz'. Unfortunately you have to
# be in the internet to have access to www.opensolaris.org
# hopefully this will change in the future.

# Here is the list of packages I installed for the showcase:

# SUNWgnu-coreutils

# SUNWgcmn

# SUNWgtar    needed for installing MySQL tarball

# SUNWuiu8

# SUNWman    can't live without it

# SUNWless

# SUNWpkgcmds   to use pkgadd later with MySQL

That's it. We have a zone called TEMPLATE. Next blog will be cloning to define 4 identical machines.
