Installation

If you have already Red Hat Enterprise Linux 7 (RHEL 7) or CentOS 7 in use you probably found out, that it is not that easy to install MySQL Enterprise Server because there are already pre-installed MariaDB 5.5 libraries:

shell> yum localinstall mysql-commercial-client-5.7.16-1.1.el7.x86_64.rpm mysql-commercial-libs-5.7.16-1.1.el7.x86_64.rpm mysql-commercial-server-5.7.16-1.1.el7.x86_64.rpm mysql-commercial-common-5.7.16-1.1.el7.x86_64.rpm

I wanted to install MySQL Galera Cluster 5.6 on the new Ubuntu 14.04 with provided packages. It was a bit tricky to make it work.

apt-get update
apt-get install mysql-server   # this is still 5.5
# from universe
apt-get install mysql-server-5.6 mysql-client-5.6 mysql-client-core-5.6

So far so good. Everything works fine as MySQL 5.6.

Now we have to download Galera 5.6 from Coderships website:

wget https://launchpad.net/galera/3.x/25.3.5/+download/galera-25.3.5-amd64.deb
wget …

A customer asked:

I would like to know if the FromDual Performance Monitor for MySQL works with Zabbix 2.0?

We do not know yet (June 2012). This is a project for this summer… We do not expect any problem if the Zabbix 2.0 interfaces have not changed significantly.

This customer kindly tested fpmmm on Zabbix 2.0 for us.

Hi, we have a Zabbix monitoring solution up and running here but now we want to add additional database monitoring. Although I followed your installation guide I was not able to get the database monitoring online. Here I’m checking from my Zabbix installation towards the same host: sudo -u zabbix zabbix_get –host=192.168.0.10 –source-address=192.168.0.10 –key=“FromDual.MySQL.check” ZBX_NOTSUPPORTED Template is applied to the host configuration. If I fire up the perl script I …

In my set-ups I have different MySQL versions (MySQL 5.0, 5.1, 5.5 and 5.6, Percona Server 13.1 and 24.0, MariaDB 5.2.10, 5.3.3, Galera 1.0, 1.1 and 2.0) running in parallel at the same time.

Up to now I have not found a practical way yet to do this with RPM or DEB packages. If anybody knows how to do it I am happy to hear about it.

So I love and need only binary tar balls. Installation and removal is done within seconds and no remainings are left over after a removal. To operate the whole I use myenv.

One of our partners recently asked me on what platforms do we usually see MySQL installed out there…

The last 5 years I gave the answer: Typically it is 80% Linux, 10% Windows, 5% Solaris and 5% all others. But this was only the picture of my limited view and I was not sure how objective this was.

This time I really wanted to know it and so I collected the information of about 570 MySQL installations of customers.

The following numbers came out:
