OULibraries.centos7

Base CentOS7 role for OULib.

Requirements

A target system running CentOS7x.

Role Variables

• Disable IPv6

In some instances we want to enable or disable IPv6. The following boolean variable controls this:

centos7_ipv6_disable: true

True will disable IPv6 and False will not change the CentOS default and keep iPv6 enabled.

This role disabled IPv6 by default. Please note this is not an idempotent config change. If IPv6 is disabled it will need to be manually enabled.

vpshere tagged tasks expect server_name, server_ip, and broker_ip.

• servername is the value for the hostname. Defaults to current FQDN.
• server_ip sets the NIC address (Gateway, Netmask, and DNS should already be configured in your base image). Defaults to current address. We set this because we set the IP after firing up a base box on a known addres.
• centos7_iptables contains a list of firewall exceptions for vmware and bare metal installs. If you leave this empty, say goodby to ssh access. example below

centos7_iptables:
  - rule_name: Some SSH Broker
    source_ip: 192.168.0.2/32
    tcp_port: 22
  - rule_name: HTTP
    source_ip: 0.0.0.0
    tcp_port: 139
  - rule_name: HTTPS
    source_ip: 0.0.0.0
    tcp_port: 443

Dependencies

Written with lastpass-cli in mind. Role information forthcoming

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  roles:
     - { role: username.rolename, x: 42 }
