Linux Administration Cookbook

Getting ready

In this section, we are going to again use our CentOS VM from our Vagrantfile, as everything we're doing is universally applicable. 

SSH to your CentOS VM:

$ vagrant ssh centos7

Move into the /home directory (up one level) and create a file, a directory, and a file in that directory:

$ cd /home$ sudo touch permissionfile$ sudo mkdir permissiondir$ sudo touch permissiondir/permissionfile-in-permissiondir

We're also going to create another dummy user that we can use to explain what we're doing in this section:

$ sudo adduser packt -s /bin/bash -p '$1$2QzaOp2Q$Ke2yWZ1N2h4rk8r8P95Sv/'

Note the password we've set here is 'correcthorsebatterystaple'.
