Continuing Tomcat Installation with Ansible
- For the link for installing tomcat Refer Here
- Refer Here for the list of ansible modules
- Extract the tar file
sudo tar -xf /tmp/apache-tomcat-${VERSION}.tar.gz -C /opt/tomcat/
- Refer Here for the changes done
- Since the tar file is present on the ansible node, we have to remote_src Refer Here for the changes
- Create a link to the new folder
sudo ln -s /opt/tomcat/apache-tomcat-${VERSION} /opt/tomcat/latest
* Now change the folder permissions
sudo chown -R tomcat: /opt/tomcat
- Refer Here for the changes done
* Change the permissions of all executables
sudo sh -c 'chmod +x /opt/tomcat/latest/bin/*.sh'
- Written the ansible module to find all the shell files and print the files found. Refer Here
- The result which we got is

- We need to iterate this list of files now and for every file we need to add execute permission
- Loops in Ansible Refer Here
- Lets run some examples
---
- name: loops demo
hosts: all
gather_facts: no
tasks:
- debug:
msg: "{{ item }}"
loop:
- Ansible
- Kubernetes
* Refer Here for the changes done
* Now execute the playbook and verify the permissions of the shell files
* Now we need to create a SystemD unit file Refer Here
- Refer Here for copy module and Refer Here
- Refer Here for the changes done to install tomcat and enable, start tomcat service
- Execute the playbook and access the
http://<public-ip-node>:8080
- Exercise: Refer Here for the documentation. Install Open JDK 11 on redhat 7 and install the tomcat 9 by following steps.
