In the third episode of DevOps&Chill, we create an Ansible playbook to automate the steps necessary to install and set up a LEMP server on Ubunbtu 18.04, using a couple DigitalOcean droplets as nodes.
This video was edited from the original stream in order to be more succinct and in a faster pace.
The Playbook
The final playbook we created in this video is included below for easier access:
---
- hosts: all
become: yes
vars:
- install_packages: [ "nginx", "php-fpm", "mysql-server", "python3-pymysql" ]
- http_port: 80
- http_host: "{{ ansible_facts.eth0.ipv4.address }}"
tasks:
- name: Update cache and Install Required Packages
apt:
name: "{{ install_packages }}"
state: latest
update_cache: yes
- name: Removes anonymous MySQL accounts
mysql_user:
name: ''
host_all: yes
state: absent
login_unix_socket: /var/run/mysqld/mysqld.sock
no_log: true
- name: Allow access on port 80
ufw:
rule: allow
port: '80'
proto: tcp
- name: Set Up Nginx default site
template:
src: nginx.conf.j2
dest: /etc/nginx/sites-available/default
notify: restart nginx
- name: Set Up php test page
template:
src: phpinfo.php.j2
dest: /var/www/html/info.php
handlers:
- name: restart nginx
service:
name: nginx
state: restarted
To run this playbook, you'll need an Ansible Control Node set up with at least one managed node in your inventory file. Then, you can execute this with the following command:
ansible-playbook -i hosts lemp-playbook.yml -u USER
Where hosts is your inventory file name, and USER is the remote user you're using to connect via SSH on the remote server and run the Ansible commands. This should be either a sudo user or root.
