Deploying Puppet scripts to a new server

After UCIT has created a new server, the following steps must be completed manually before deploying the Puppet scripts.

1. Get the latest updates:
   sudo yum update

2. Install packages needed my Puppet:
   sudo yum install openssl-devel zlib-devel gcc gcc-c++ git

3. Install ruby:
   wget http://digital.libraries.uc.edu/puppet/scholar/ruby-2.4.1.tar.gz
tar -xzf ruby-2.4.1.tar.gz
cd ruby ./configure --prefix=/usr make sudo /usr/bin/make install ruby -v

4. Install Puppet: cd ~ sudo gem install puppet -v 4.5.3 puppet --version

5. Relax restrictions for using sudo: sudo chmod u+w /etc/sudoers sudo vim /etc/sudoers (comment out this line: Defaults requiretty) sudo chmod u-w /etc/sudoers

6. Stop and disable the firewall service: sudo systemctl stop firewalld.service sudo systemctl disable firewalld.service
