前提：

1、已配置好hosts文件且免密碼登錄

2、需要的yaml文件已上傳到主控端

一、使用Ansible安裝nginx

1、nginx.yaml文件

 1 ---
 2 - hosts: clong
 3   remote_user: root

31       shell: /usr/sbin/nginx -t -c /etc/nginx/nginx.conf
32     # 刪除默認的default.conf文件
33     - name: delete default.conf  
34       file: path=/etc/nginx/conf.d/default.conf state=absent
35     # 復制www站點文件
36     - name: copy www conf
37       copy: src=www.conf dest=/etc/nginx/conf.d/www.conf backup=yes force=yes
38       notify: restart nginx
39     # 重啟nginx
40   handlers:
41     - name: restart nginx
42       service: name=nginx state=restarted
43     # --syntax-check

2、nginx.conf文件

3、www.conf文件

 1 server {
 2     listen       80;
 3     server_name  localhost;
 4     
 5     location / {
 6         root   /usr/share/nginx/html;
 7         index  index.php index.html index.htm;
 8     }
 9 
10     location ~ \.php {

16     }
17     access_log  /var/log/nginx/host.access.log  main;
18 }

4、nginx.repo文件

1 [nginx]
2 name=nginx repo
3 baseurl=http://nginx.org/packages/centos/7/$basearch/
4 gpgcheck=0
5 enabled=1

使用Ansible安裝部署nginx+php+mysql
