Installing and learning Ansible

November 18, 2016

I am learning Ansible and am documenting my progress. I built two Centos 7 test servers, the main one is called Ansible and the remote server is test1.

To install Ansible first add the EPEL Repository for Centos 7

rpm -iUvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

Now you can install it.

yum install Ansible

Check for version installed.

# ansible –version
ansible 2.1.2.0
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides

Create an inventory file, I named the file hosts. The remote server is called test1. I created a group called web-server, this will be helpful if I have more than one server. I can then reference it by the group name.

# cat hosts
[web-server]
test1

site.yml

site.yml

Below is the content of my first playbook called site.yml, I have been appending to it so it continues to grow as I learn Ansible.

# cat site.yml
– name: Install Packages
hosts: web-server
remote_user: root

tasks:
– name: Installing Latest version of Apache
yum: name=httpd state=present

– name: Copy default web page
template: src=/root/work/index.html dest=/var/www/html
owner=apache group=apache mode=0644

– name: Start httpd
service: name=httpd state=restarted enabled=yes

– name: Install all PHP packages
yum: name={{item}} state=present
with_items:
– php
– php-fpm
– php-mysql
– php-xml

– name: Install MySQL
yum: name=mysql-server state=present

MySQL has been replaced with MaridDb in Centos 7. Since I am familiar with MySQL I decided to install that instead. I had to install the repository for MySQl to do that.

Download mysql community repository and install it. I did this on the remote server test1.

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm

To run the playbook use the command ansible-playbook. To prompt for the password use –ask-pass.

# ansible-playbook –ask-pass -i ./hosts site.yml
SSH password:
