Installing ESM is Very Easy (part I)


Feb 22, 2016

When we talk to customers about our Enterprise Session Monitor for SAS, often one of the first questions we’re asked is ‘How easy is this to install’?

The answer to this question is, it’s very easy. We’re particular about User Experience here at Boemska, so we’ve put a lot of effort into ensuring that the deployment (and removal) of ESM is as effortless as possible.

Of course, it’s very easy for us to just say it’s very easy. So for this post I thought I’d show you. Here’s a recording I made a couple of days ago, showing a fresh installation of MySQL, ESM Server and ESM Agent on a headless cloud instance of CentOS.

Pretty neat. I love asciinema. If we consider that most of the 7m49 recording is of me correcting the typos in my commentary, I think we could even call this a ‘Five Minute Installation’.

Here are a couple of additional things to consider when managing your own CentOS / RHEL instance:

Always update your installation before you do anything else:

$ # Update your packages:
$ sudo yum update

Depending on your distro, mysql-community-server may have at some point been displaced by mariadb in the stock package repositories. With CentOS 7.1 I needed to add the MySQL repo information (as described in the MySQL docs here).

First, get the MySQL repo information for the el7 release:

$ # Download the official RPM for the MySQL repo: 
$ wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

Install the downloaded repo package. You can do this via either rpm or yum.

$ # Install the downloaded release package:
$ sudo yum install mysql-community-release-el7-5.noarch.rpm

Update the package manager again so that it knows about the available mysql-community-server packages:

$ # Update your packages:
$ sudo yum update

Apart from this, installation steps shown in the recording should apply universally.

So there it is – a typical ESM installation. Some small changes will still need to be made to a few SAS config files, in order for SAS to report in to ESM correctly. I’ll cover these configuration steps in my next post. Stay tuned.
