运维自动化之ansible playbook安装nginx

786yr

绍一下如何使用playbook安装nginx。下面是安装nginx的信息：

1 2 3 4 5 6 7

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

playbook的nginx安装是

1 2 3 4 5 6 7 8 9

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

1 2 3 4 5 6 7 8

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

2、安装后测试

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

可与看到安装成功，并且软件名与版本都隐藏了
3、删除nginx

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/ansi ... aster/nginx_install），然后放到/etc/ansible目录里，下面是内容
