Ansible-playbook(安装Apache)

练习

1. 所有web主机安装Apache
2. 修改配置文件的监听端口为8080
3. 设置默认主页 hello world
4. 启动服务
5. 设置开机自启

服务器规划

MANAGER(管理机) : IP 192.168.1.10
WEB1: IP 192.168.1.21
WEB2: IP 192.168.1.22

安装前提: (需要进入ansible文件中运行"/etc/ansible")

1. ansible的基本配置已经完成,如下图:

[root@manager ansible]# ansible web -m ping
web1 | SUCCESS => {
    
    
    "changed": false, 
    "ping": "pong"
}
web2 | SUCCESS => {
    
    
    "changed": false, 
    "ping": "pong"

2.所有机器的YUM源配置完成.

[root@web1 ~]# yum repolist
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
源标识                   源名称                                           状态
base/7/x86_64            CentOS-7 - Base - mirrors.aliyun.com             10,097
extras/7/x86_64          CentOS-7 - Extras - mirrors.aliyun.com              323
local_repo               CentOS-7 - Base                                   9,911
updates/7/x86_64         CentOS-7 - Updates - mirrors.aliyun.com           1,446
repolist: 21,777

开始写YAML文件

[root@ansible ansible]# vim http.yml

---
- hosts: web
  remote_user: root
  tasks:
    - name: install one specific version of Apache
      yum:
        name: httpd        //安装Apache
        state: installed
    - lineinfile:
        path: /etc/httpd/conf/httpd.conf
        regexp: '^Listen '
        line: 'Listen 8080'        //修改端口为8080
    - service:
        name: httpd
        enabled: yes        //开机自启
        state: restarted
    - copy:
        src: /root/index.html        //修改主页，可以自己写个页面
        dest: /var/www/html/index.html

运行时,需要将以"//"注释信息删除,以免报错!

[root@manager ansible]# echo 'hello world' > /root/index.html

[root@manager ansible]# ansible-playbook http.yml
