How to run tomcat catalina script on Ansible
(2 answers)
Closed 5 years ago.
I've been working on ansible playbook to download and start tomcat in a host.
This is my inventory host file:
[group1]
machine1 ansible_host=10.40.0.168
I have group1.yml file in my group_vars:
---
ansible_ssh_user: user
ansible_ssh_pass: pass
ansible_sudo_pass: passp
My playbook is:
---
- hosts: group1
sudo: yes
tasks:
- name: Update all packages to the latest version
apt:
upgrade: dist
- name: Download tomcat
get_url: url=http://mirrors.up.pt/pub/apache/tomcat/tomcat-9/v9.0.1/bin/apache-tomcat-9.0.1-fulldocs.tar.gz dest=/opt/apache-tomcat-9.0.1.tar.gz
- name: Unarchive a file that is already on the remote machine
unarchive:
src: /opt/apache-tomcat-9.0.1.tar.gz
dest: /opt/
remote_src: yes
- name: Run Tomcat
shell: ./startup.sh
args:
chdir: /opt/apache-tomcat-9.0.1/bin
I try to run ./startup.sh in /opt/apache-tomcat-9.0.1/bin folder to start tomcat.
I run the following command:
ansible-playbook playbookname.yml
If I run ./startup.sh in a host machine it works fine, but when I run it from the control machine I get:
PLAY [group1] **********************************************************************************************************
TASK [Gathering Facts] *************************************************************************************************
ok: [myname]
TASK [Update all packages to the latest version] ***********************************************************************
ok: [myname]
TASK [Download tomcat] *************************************************************************************************
ok: [myname]
TASK [Unarchive a file that is already on the remote machine] **********************************************************
ok: [myname]
TASK [Run Tomcat] ******************************************************************************************************
changed: [myname]
PLAY RECAP *************************************************************************************************************
myname : ok=5 changed=1 unreachable=0 failed=0
After this I try to open tomcat, but it's not running on the host.
How can I start tomcat from ansible?

Answer 1

You should add it as a service, eg as below:
service file: /etc/systemd/system/tomcat.service (It should be in target destination machine)
File should contain as below, (Adjust to your java environment)
[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target
[Service]
Type=forking
Environment=JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk/jre
Environment=CATALINA_PID=/opt/tomcat/apache-tomcat-8.0.47/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat/apache-tomcat-8.0.47
Environment=CATALINA_BASE=/opt/tomcat/apache-tomcat-8.0.47
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'
ExecStart=/opt/tomcat/apache-tomcat-8.0.47/bin/startup.sh
ExecStop=/bin/kill -15 $MAINPID
User=tomcat
Group=tomcat
[Install]
WantedBy=multi-user.target
Then start the server with below systemd ansible module,
- name: enable tomcat startup
systemd:
name: tomcat
enabled: yes
state: restarted
become: true

You should use system tools for that, like Systemd etc. depending on your OS.
Ansible should only create the service file and start the service. Running the servie is not the job of Ansible.
