Installing SIMP on an existing system

http://simp.readthedocs.io/en/master/getting_started_guide/Installing_SIMP_From_A_Repository.html

Server

1. Install all the required repos: You only need the SCL repo for Ruby 1.9.3 if you are using CentOS 6. CentOS 7 comes with Ruby 2.0.

   Repos

   $ sudo yum install epel-release -y
   $ sudo curl http://people.redhat.com/bkabrda/scl_ruby193.repo > /etc/yum.repos.d/scl_ruby193.repo

2. Import the SIMP GPGKEY

   Import SIMP GPGKEY

   $ curl https://raw.githubusercontent.com/NationalSecurityAgency/SIMP/master/GPGKEYS/RPM-GPG-KEY-SIMP | gpg --import -

3. Add the SIMP repo by adding a new file in /etc/yum.repos.d/SIMP.repo containing the following:

   Add the BinTray repo!

   # For EL 7
   $ sudo wget https://bintray.com/simp/5.1.0-3/rpm -O /etc/yum.repos.d/bintray-simp-5.1.0-3.repo
    
   # For EL6
   $ sudo wget https://bintray.com/simp/4.2.0-2/rpm -O /etc/yum.repos.d/bintray-simp-4.2.0-2.repo

4. Install SIMP!

   Install SIMP

   $ sudo yum install simp

5. Set the following variables to repositories of your choosing in /etc/puppet/environments/production/hieradata/default.yaml

   default.yaml

    ---
   "simp::yum::os_update_url": "http://mirror.centos.org/centos/$releasever/os/$basearch/"
   "simp::yum::simp_update_url": "http://dl.bintray.com/simp/5.1.0-3"

   • simp::yum::os_update_url
     
     • Full URL to a YUM repo for Operating System packages
   • simp::yum::simp_update_url
     
     • Full URL to a YUM repo for SIMP packages
6. You will also have to re-enable the repos in /etc/yum.repos.d/CentOS-Base.repo after simp config.

Client

SIMP doesn't have a set way to add SIMP Clients. SIMP is a framework and you can add clients as you would a normal puppet client.

You can also download the runpuppet script from your SIMP server:

$ curl http://puppet.server.fqdn/ks/runpuppet > runpuppet
$ chmod +x runpuppet
$ ./runpuppet
