本案例要求：

• 安裝Apache並修改監聽端口為8080
• 修改ServerName配置，執行apachectl -t命令不報錯
• 設置默認主頁hello world
• 啟動服務並設開機自啟

---
- hosts: cache
  remote_user: root
  tasks:
    - name: install one specific version of Apache
      yum:
        name: httpd        //安裝Apache
        state: installed
    - lineinfile:
        path: 
 
/etc/httpd/conf/httpd.conf
        regexp: ‘^Listen ‘
        line: ‘Listen 8080‘        //修改端口為8080
    - replace:
        path: /etc/httpd/conf/httpd.conf
        regexp: ‘^#(ServerName).*‘        //配置ServerName
        replace: ‘\1 localhost‘
    - service:
        name: httpd
        enabled: yes        //開機自啟
        state: restarted
    
 
- copy:
        src: /root/index.html        //修改主頁，可以自己寫個頁面
        dest: /var/www/html/index.html

擴展的一個tags和notify以及handlers

---
- hosts: web1
  remote_user: root
  tasks:
    - name: install the latest version of Apache
      yum:
        name: httpd
        state: latest
    - replace:
        path: 
 
/etc/httpd/conf/httpd.conf
        regexp: ‘(^Listen).*‘
        replace: ‘\1 8080‘
        backup: yes
    - replace:
        path: /etc/httpd/conf/httpd.conf
        regexp: ‘(^#ServerName ).*‘
        replace: ‘\1 localhost‘
        backup: yes
    - copy:
        src: test1.yml
        #src: /root/index.html
        dest: /root/user13.yml
        #dest: /var/www/html
        owner: apache
        group: apache
        mode: 0644
      tags: haha
      notify:
        - restart httpd
        - restart vsftpd
        - modify port
  handlers:
    - name: modify port
      replace:
        path: /etc/httpd/conf/httpd.conf
        regexp: ‘(^Listen ).*‘
        replace: ‘\1 80‘
        backup: yes
    - name: restart httpd
      service: name=httpd state=restarted
    - name: restart vsftpd
      service: name=vsftpd state=restarted
    - service:
        name: httpd
        state: restarted
        enabled: yes

註意格式要求，一般的copy，replace，yum，sevice模塊用ansible-doc 模塊名 查看幫助就ok
