Learning Resources For Using Ansible 1 Click Install WordPress, Nginx Playbook For Ubuntu 16.04
For the sake of learning Ansible, unless you already used Ansible before, reading guides like Getting Started With Ansible, Tutorial on Ansible Playbooks is mandatory need. For this tutorial, we will one server configuration, which is most easy. We have some existing good Playbooks to start with :
---

We can easily install Ansible with these commands :
|
1 2 3 4 |
sudo easy_install pip sudo pip install ansible sudo pip install --upgrade ansible ansible --version |
Current version of Ansible is 2.1 and ansible-2.1.0.0.tar.gz is 1.9MB in size.

Steps For Cteating Ansible 1 Click Install WordPress, Nginx Playbook for Ubuntu 16.04.04
Because of the changes in Ubuntu 16.04 compared to Ubuntu 14.04 and our preferance towards Percona MySQL, we need to start from scratch. In other words, we will create Ansible version of our step by step guide to Install WordPress, Nginx on Ubuntu 16.04. As you are I are different, you may need to create your own, instead of blindly running ours!
|
1 2 3 4 |
cd ~ mkdir wordpress-ansible && cd wordpress-ansible touch playbook.yml && touch hosts mkdir roles && cd roles |
Now, we will proceed to bootstrap our roles with the Ansible tool called ansible-galaxy. For each role, we will run ansible-galaxy init. It is kind of “automatic system” to create the structure :
|
1 2 3 4 |
ansible-galaxy init server ansible-galaxy init php ansible-galaxy init mysql ansible-galaxy init wordpress |
You’ll get response like –
|
1 |
- server was created successfully |
Now, we will edit the hosts file with nano ~/wordpress-ansible/hosts or vi ~/wordpress-ansible/hosts command and add the working block :
|
1 2 |
[wordpress] 127.0.0.1 |
127.0.0.1 is example of your server’s IP. If you work from server, 127.0.0.1 obviously work. Now we will edit playbook.yml with nano ~/wordpress-ansible/playbook.yml or vi ~/wordpress-ansible/playbook.yml command and make it looking like this :
|
1 2 3 4 5 6 7 |
- hosts: wordpress roles: - server - php - mysql - wordpress |
Again we will go back to ~/wordpress-ansible/ directory to run and check whether it is fine :
|
1 |
ansible-playbook playbook.yml -i hosts -u root -K |
We have not installed anything with the above command. Now we will create tasks. We will create the needed file with vi ~/wordpress-ansible/roles/server/tasks/main.yml or nano ~/wordpress-ansible/roles/server/tasks/main.yml command and add :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 |

CD to ~/wordpress-ansible/roles/server/templates and add the my.cnf and default from our step by step guide to Install WordPress, Nginx on Ubuntu 16.04.
Now, in PHP’s role, we will create the needed file with vi ~/wordpress-ansible/roles/php/tasks/main.yml or nano ~/wordpress-ansible/roles/php/tasks/main.yml command and add :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |

Now, we will create the needed file for MySQL with the command nano ~/wordpress-ansible/roles/mysql/defaults/main.yml command and add :
|
1 2 3 4 5 6 |
--- # defaults file for mysql wp_mysql_db: wordpress wp_mysql_user: wordpress wp_mysql_password: wp_db_password |
In the next step, we will create the needed file for MySQL with the command nano ~/wordpress-ansible/roles/mysql/tasks/main.yml command and add :
|
1 2 3 4 5 6 7 8 9 10 11 |
--- # tasks file for mysql - name: Create mysql database mysql_db: name={{ wp_mysql_db }} state=present - name: Create mysql user mysql_user: name={{ wp_mysql_user }} password={{ wp_mysql_password }} priv=*.*:ALL |
For WordPress, we will edit with the command nano ~/wordpress-ansible/roles/wordpress/tasks/main.yml and add :
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |
--- # tasks file for wordpress - name: Download WordPress get_url: url=https://wordpress.org/latest.tar.gz sha256sum="{{ wp_sha256sum }} dest=/tmp/wordpress.tar.gz validate_certs=no - name: Extract WordPress unarchive: src=/tmp/wordpress.tar.gz dest=/usr/share/nginx/html copy=no sudo: yes - name: Copy sample config file command: mv /usr/share/nginx/html/wordpress/wp-config-sample.php /usr/share/nginx/html/wordpress/wp-config.php creates=/usr/share/nginx/html/wordpress/wp-config.php sudo: yes - name: Update WordPress config file lineinfile: dest=/usr/share/nginx/html/wordpress/wp-config.php regexp="{{ item.regexp }}" line="{{ item.line }}" with_items: - {'regexp': "define\\('DB_NAME', '(.)+'\\);", 'line': "define('DB_NAME', '{{wp_mysql_db}}');"} - {'regexp': "define\\('DB_USER', '(.)+'\\);", 'line': "define('DB_USER', '{{wp_mysql_user}}');"} - {'regexp': "define\\('DB_PASSWORD', '(.)+'\\);", 'line': "define('DB_PASSWORD', '{{wp_mysql_password}}');"} sudo: yes - name: Move WordPress to root raw : mv /usr/share/nginx/html/wordpress/* /usr/share/nginx/html sudo: yes - name: Fix CGI PATH raw : echo "cgi.fix_pathinfo=0" >> /etc/php5/cgi/php.ini sudo: yes |
Again we will go back to ~/wordpress-ansible/ directory to run for final WordPress installation :
|
1 |
ansible-playbook playbook.yml -i hosts -u root -K |
Now you can create millions of WordPress server with your Playbook. You learned how to copy template, how to remove files, how add repository in Ansible.
