Ansible Contd

• Lets try to install tomcat 9 with open jdk 11
• We have two linux distributions
  • ubuntu 20.04
  • Redhat 7.x
• Ubuntu Tomcat manual implementation Refer Here
• Useradd: sudo useradd -m -U -d /opt/tomcat -s /bin/false tomcat
  • -m create home directory
  • -U create a group with the same name as the user
  • -d home directory (/opt/tomcat)
  • -s login shell for the user /bin/false
  • tomcat => username
• Lets find a ansible module for useradd Refer Here
• Refer Here for examples of user module
• Refer Here
• We got the following failure group doesnot exists
  
• We have two options, create a group or donot pass group parameter. Refer Here for the changeset
  
• Now lets login and check the user details on the ubuntu node by executing cat /etc/passwd
  
• Download the tomcat to the /tmp directory

VERSION=9.0.60
wget https://dlcdn.apache.org/tomcat/tomcat-9/v${VERSION}/bin/apache-tomcat-${VERSION}.tar.gz -P /tmp

* The module for downloading from web is get_url Refer Here
* Refer Here for the changes done

* Now lets manually verify this

• Extract the tar file

sudo tar -xf /tmp/apache-tomcat-${VERSION}.tar.gz -C /opt/tomcat/

• 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
sudo sh -c 'chmod +x /opt/tomcat/latest/bin/*.sh'
