Now that installing MySQL in Solaris zones is even officially
supported by the MySQL support group (see http://www.mysql.com/about/legal/supportpolicies/policies-06.html#q03),
the question is: What is the right way of installing MySQL in a
zone. Of course this depends on what you want to achieve. The
following description is based on Solaris 10. On Opensolaris this
is different (somewhat easier, as there are no more sparse root
zones.)
If you run a local zone as a whole root zone, you can easily
install MySQL from tarball or the package installer.
If you run a local zone as a sparse root zone, there are
different options:
First you cannot use the package installer, as this procedure
will copy binaries to /usr/bin. But /usr/bin is inherited from
the global zone and write protected. You have to use the tarball
installation. …
Hi,
If by any chance you are at the MySQL user conference in Santa Clara conference center, there are some great possibilities to see MySQL and Solaris Cluster in action.
We have a demo at the exhibition hall, where you can see MySQL with zone cluster and MySQL with SC Geographic Edition.
I will host a birds of a feather at Wednesday 4/22/09 evening in meeting room 205 at 7 pm. The Title is "Configuring MySQL in Open HA Cluster, an Easy Exercise" check out the details here.
I will give a presentation at Thursday 4/23/09 morning 10:50 in Ballroom G, the title is "Solutions for High Availability …

THIS BLOG POST GIVES WRONG ADVICE. DON'T DO THIS!
As the zones use ZFS as root filesystem it's easy to do a zfs
snapshot/clone to reproduce a zone. The different zones have only
one difference: They differ in /etc/nodename, they have different
rootpaths and they have different IP addresses.I wrote a script
to read from global's /etc/hosts the ip address. Zonerootpath is
/zones/zonename and /etc/nodename must contain as well. The
name of the zone is always identical to the hostname of the zone.
That rule is not from OpenSolaris but from me. ;-)
Here is my script: Beware: I hate to do a lot of checking. This
is not for general use...
#!/bin/bash
echo "Creating zone $1 from zone TEMPLATE"
echo check if $1 does not already exist...
zoneadm list -cv | grep $1 && exit -1
echo -n "Retrieving TEMPLATE's IP: "
TEMPLATE_IP=$(grep TEMPLATE /etc/hosts | nawk '{print $1}') …
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 …
Background Knowledge
I’m trying to determine the difference in minutes between two timestamps. I’m using Pear::Date to do this. The issue comes into play when I noticed that the wrong timezone was being used by Pear::Date, UTC. If I do not use Pear::Date the timezone is set correctly.
I have tried using date_default_timezone_set() and it does set the timezone back, however I feel this shouldn’t be necessary as the default timezone should be used. I have been using date_default_timezone_get() to determine what timezone is being used.
It’s my understanding that Pear::Date uses UTC when it is unable to determine the default timezone. As far as I know I have the default timezone set correctly and with a …
