Step 1: Configure Ansible

By default ansible host configuration file is /etc/ansible/hosts Here you need to add the redis server details like this, Use the following step for the same, In my case i have 1 apache server.

Group Name – WebServer
IP Address – Your IP Address
Username – example
Password – XXXXXXXXXX

You need to add your server in ansible host file, Syntax is given below, You need to open the /etc/ansible/hosts file with nano or vim text editor.

sudo vim /etc/ansible/hosts

and add the web server entry like this.

[redis]
localhost ansible_connection=ssh ansible_ssh_user=ubuntu ansible_ssh_pass=xxxxxxx

Change the credentials as per your environment, Save and exit from the vim text editor and verify the host machine connectivity with ansible by using the given command.

ansible all -m ping

You should get output like this.

Here our host configuration is completed and now we can go for next step to write play book.

Step 2: Creating Redis Playbook

You need to create a redis-playbook.yml and you change it according to your requirement.

sudo vim redis-playbook.yml

Paste the given code.

- hosts: redis
  become: yes

    - name: Update
      apt: update_cache=yes

      notify:
        - restart redis.service 

    - name: Restart Redis Server
      service: name=redis state=restarted enabled=yes

Now we are ready to use the Redis’s PlayBook, To execute the PlayBook you need to use the given command.

ansible-playbook redis-playbook.yml
