Step 1: Configure Ansible 

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

• Group Name  – tomcat
• 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.

[tomcat]
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

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

Step 2: Creating Tomcat Playbook

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

sudo vim tomcat-playbook.yml

Paste the given code.

- hosts: tomcat
  become: yes

    - name: update
      apt: update_cache=yes   
      ignore_errors: yes 
   
    - name: Installating JDK.
      apt: name=default-jdk state=latest

    - name: Adding Group and user for Tomcat.

      shell: tar -xzvf /tmp/apache-tomcat-8*tar.gz -C /opt/tomcat --strip-components=1
      
    - name: Updating permission.
      command: "{{ item }}"
      with_items:
        - chown -R tomcat:tomcat /opt/tomcat
        - chmod -R g+r /opt/tomcat/conf
        - chmod g+x /opt/tomcat/conf
                   
    - name: Creating service for Apache tomcat.
      file:
        path: /etc/systemd/system/tomcat.service
        state: touch
        mode: u+rwx,g-rwx,o-x

    - name: download foo.conf
      get_url:
        url: https://raw.githubusercontent.com/aftab70/Apache_Tomcat/master/tomcat_services
        dest: /etc/systemd/system/tomcat.service
 
    - name: Deamon reload.
      command: systemctl daemon-reload
 
    - name: Starting Apache Tomcat service.
