For MySQL Enterprise Monitor an agent is required. I've downloaded
V23981-01.zip from https://edelivery.oracle.com which contains mysqlmonitoragent-2.3.1.2044-linux-glibc2.3-x86-64bit-installer.rpm

When I was testing the email alerting for my backup script I got an error:

/etc/mail/submit.cf: line 544: fileclass: cannot open '/etc/mail/trusted-users': Group

Luckily RPM was able to tell me that mysqlmonitoragent had set / to the wrong permissions.

But unfortunately the MySQL package (mysql-server) that comes bundled with RHEL 5.5 or CentOS 5.5 is fairly old (5.0.77). What if you want to install the latest stable version of MySQL yet have the advantage of removing/re-installing the software using rpm(8)?

In this blog post, I will guide you with compiling MySQL from source code yet installing the software through rpm(8) so that we tune and …

It’s worth noting that Red Hat Enterprise Linux (RHEL) 5 has had an update to MySQL in the last month. This naturally means that CentOS 5 also had a similar update. It’s now bumped up to MySQL 5.0.77 (goodbye 5.0.45!; which is what RHEL5 shipped with). This is a moderate security release, so consider updating, if you can afford a mysqld restart.
