• CentOS7.x
• Internet Connection
• Ansible account configured (ansible/ansiRods)

• IP addresses of machines in formation
• Passwordless access to a sudo account on machines

The most important file to operate this is the "hosts" file. This file contains all of the definitions and options used during machine setup. An example entry looks like this:

145.100.58.13

NOTE: Only one host machine per line.

However, we can configure multiple servers with some customized options. This example creates two machines, an iCAT and a Resource server:

145.100.58.13
145.100.58.14 svrType="resc" rescICAT="145.100.58.13"

NOTE: If creating a resource server, rescICAT must be defined as the iCAT to the resource server. It can be one built by this playbook.

These host files can have as many variables as you wish to customize, see below for a comprehensive table.

1. Cone the repository

git clone https://git.ia.surfsara.nl/data-management-services/ansible
cd ansible/iRODS-4-X-X

2. Configure your host file with the correct information

vi hosts

3. Run the playbook

ansible-playbook -i hosts build.yml

NOTE: If the account requires a password for sudo commands, use the -K option as shown here:

ansible-playbook -i hosts build.yml -K

This -K flag tells ansible that you need to enter a password, and will be prompted to do so. It must be the same across all machines if used.

It is worth noting that there are in fact several variables, all customizeable if listed in the same line as the appliciable host.

The default values listed here are defined in the lower portion of the hosts file.
