create Solr server with ansible roles from Galaxy

Apache Solr is a fast and scalable search server optimized for full-text search, word highlighting, faceted search, fast indexing, and more. It’s a very popular search server, and it’s pretty easy to install and configure using Ansible.

Step 1. Getting roles from Galaxy
https://galaxy.ansible.com/

ansible-galaxy install geerlingguy.java geerlingguy.solr

Step 2. create solr.yml

---
- hosts: all
  become: yes
  
  roles:
    - geerlingguy.java
    - geerlingguy.solr

Step 3. run it with ansible-playbook solr.yml, then you can open http://ubuntu2004:8983/solr

if you didn’t install roles, the playbook.yml could be:

---
- hosts: all
  become: true

  vars_files:
    - vars.yml

  pre_tasks:
    - name: Update apt cache if needed.
      apt: update_cache=true cache_valid_time=3600

  tasks:
    - name: Install Java.
      apt: name=openjdk-11-jdk state=present

    - name: Download Solr.
      get_url:
        url: "https://archive.apache.org/dist/lucene/solr/{{ solr_version }}/solr-{{ solr_version }}.tgz"
        dest: "{{ download_dir }}/solr-{{ solr_version }}.tgz"
        checksum: "{{ solr_checksum }}"

    - name: Expand Solr.
      unarchive:
        src: "{{ download_dir }}/solr-{{ solr_version }}.tgz"
        dest: "{{ download_dir }}"
        remote_src: true
        creates: "{{ download_dir }}/solr-{{ solr_version }}/README.txt"

    - name: Run Solr installation script.
      command: >
        {{ download_dir }}/solr-{{ solr_version }}/bin/install_solr_service.sh
        {{ download_dir }}/solr-{{ solr_version }}.tgz
        -i /opt
        -d /var/solr
        -u solr
        -s solr
        -p 8983
        creates={{ solr_dir }}/bin/solr

    - name: Ensure solr is started and enabled on boot.
      service: name=solr state=started enabled=yes
