The recent vulnerability in bash, got me running to update bash. It’s easy when you have maybe one or two Linux servers, but what do you do if you have 100’s or even thousands or servers? You need to use a server configuration and management tool like puppet. However, instead of using the command line, I wanted a GUI tool where I could select the servers or server group and select an action.
That is where I found Foreman, A opensource tool which not only handles configuration of your servers but also does provisioning. Foreman is easy to install, opensource, has community based support and a good deal of documentation.
Installing Foreman on CentOS
Please ensure that you perform these steps on a fresh install on CentOS which has the EPEL repository.
As I said earlier, Foreman is easy to install, just run the installer below and it will install both foreman and puppet.
Adding a Host to Foreman
You can add a host to foreman by installing the puppet client, signing the certificate and then running the command below.
Click on your hostname and then click on facts, this will bring up all info about your host.
Installing a puppet module on a host
Run the below command on the foreman host.
Select httpd and click submit. You should be able to see “httpd” on the yaml tab on the next page.
Run the puppet client on the host and you should be able to see the results of a successful install in reports
Although I found creating a class from foreman a bit confusing, I was able to create a class via commandline and then import the class into foreman.
Click on Configure–Puppet Classes–Import from puppet.yourlinuxvps.net once you have created and added your class in /etc/puppet/environments/production/modules.
I could not select all hosts and add a class to them at the same time, But I like that foreman was easy to install and had a good user interface which made it easy to view reports on each hosts.
If you need to setup Puppet only then I recommend you read
A simple way to install Puppet
If you are more comfortable with Commands then I recommend you install the Saltstack.
Getting Started with the Saltstack
If any of you have used foreman or other opensource based GUI then feel free to share your feedback in the comments section.
