centos ansible 远程部署安装tomcat playbook

CentOS 和 Ansible 结合可以方便地进行远程服务器的 Tomcat 安装和配置。Ansible 是一种强大的自动化工具，通过 Playbook（剧本文件）来定义任务序列和操作步骤。

下面是一个简单的 Ansible playbook 示例，用于在 CentOS 上安装并启动 Tomcat：

---
- name: Install and start Apache Tomcat
  hosts: your_server_ip_or_hostname
  become: true
  vars:
    tomcat_version: '8.5.60'
    tomcat_dir: '/usr/local/tomcat'

  tasks:
  - name: Update packages and install Java
    yum:
      name: java-1.8.0-openjdk-devel
      update_cache: yes

  - name: Download and extract Tomcat
    unarchive:
      src: 'https://www.apache.org/dist/tomcat/{{ tomcat_version }}/bin/apache-tomcat-{{ tomcat_version }}.tar.gz'
      dest: /tmp
      remote_src: yes

  - name: Move Tomcat to the desired location and set permissions
    move:
      src: '/tmp/apache-tomcat-{{ tomcat_version }}'
      dest: '{{ tomcat_dir }}'
    file:
      owner: root
      group: root
      mode: '0755'

  - name: Configure startup script
    template:
      src: templates/init.d/tomcat.j2
      dest: '/etc/init.d/tomcat'
      owner: root
      group: root
      mode: '0755'
    notify: restart_tomcat

  - name: Create init directory if not exists
    file:
      path: /etc/init.d
      state: directory
      mode: '0755'

  - name: Enable Tomcat service at boot
    command: chkconfig tomcat on

  - name: Start Tomcat
    service:
      name: tomcat
      state: started

  - name: Check if Tomcat is running
    command: systemctl status tomcat
    register: tomcat_status
    ignore_errors: yes

  handlers:
  - name: Restart Tomcat
    service:
      name: tomcat
      state: restarted

**注意事项**:
1. 将`your_server_ip_or_hostname`替换为你实际的服务器IP地址或主机名。
2. 确保你的Ansible服务器已配置好SSH免密登录到目标服务器。
3. `templates/init.d/tomcat.j2`是一个模板文件，你需要创建它来编写启动脚本。
