Ansible automation to install Java in Linux machines

We can install Java in multiple targets / linux hosts using ansible. Here I am showing you one demo scenario to do the following tasks using Ansible:

1. Create directory

2. Unzip/Install Java software 

3. Create a symbolic link to uninstalled Java

 Create the playbook with name something like "java_install.yml".

Step#1: Create the play book

[root@demosys01 ~]#  cat java_install.yml

---

- hosts: all

  remote_user: oracle

  tasks:

   - name: Create Folder

     file:

      path: /u01/fmw/java

      mode: 0755

      state: directory

   - name: Unpack archive

     unarchive:

      src: /software/jdk-8u291-linux-x64.tar.gz

      dest: /u01/fmw/java

      remote_src: yes

   - name: Create symbolic link

     file:

      src: "jdk1.8.0_291"

      dest: "/u01/fmw/java/jdk"

      state: link

[root@demosys01 ~]#

Step#2:  Verify the playbook to check syntax errors:

# ansible-playbook java_install.yml --syntax-check

playbook: java_install.yml

#

Here, no errors found. Now go-ahed to run the play book.

Step#3: Run the play book

[root@demosys01 ~]# ansible-playbook java_install.yml

[root@demosys01 ~]#

Step#4: Now Verify in one of the target host:

verify in target host:

[oracle@example01 ]$ hostname -i

192.168.100.2

[oracle@example01 ]$ cd /u01/fmw/java

[oracle@example01 java]$ ls -l
