运维自动化之ansible playbook安装nginx

上次介绍了如何使用ansible playbook安装mysql（http://dl528888.blog.51cto.com/2382721/1437882），这次介绍一下如何使用playbook安装nginx。
下面是安装nginx的信息：

nginx_user: www                        nginx用户
nginx_port: 80                         nginx监听端口
nginx_web_dir: /data/webroot/nginx     nginx的目录
nginx_version: 1.4.3                   nginx的版本
pcre_version: 8.33                     pcre的版本
pretended_name: Tengine                为了安全起见，把nginx名字改为tengine
pretended_version: 1.5.2               隐藏版本，换个tengine的版本

备注：此playbook仅能对centos或者redhat的6.x版本进行安装。
下面是安装nginx的playbook结构

12 directories, 17 files

playbook的nginx安装是

09:34:04 # cat nginx_install.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- common
- pcre_install
- nginx_install

playbook的nginx删除为

09:35:06 # cat nginx_delete.yml
---
- hosts: "{{host}}"
remote_user: "{{user}}"
gather_facts: True
roles:
- nginx_delete
- pcre_delete

1、安装nginx

09:26:58 # time ansible-playbook nginx_install.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem

2、安装后测试

[root@ip-10-10-240-21 local]# ps -ef|grep nginx

3、删除nginx

09:28:02 # time ansible-playbook nginx_delete.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem

可与看到都删除了。
如果大家想使用我的例子，可以从github里下载（地址是https://github.com/dl528888/ansible-examples/tree/master/nginx_install），然后放到/etc/ansible目录里，下面是内容
