将所有部署nginx主机分为nginx组:

vim /etc/ansible/hosts
[nginx]
192.168.200.102

?创建管理目录:

mkdir -p nginx/roles/nginx_install/{files,handlers,meta,tasks,templates,vars}

cd nginx/

说明:

files:存放需要同步到异地服务器的源码文件及配置文件; 
handlers:当资源发生变化时需要进行的操作,若没有此目录可以不建或为空; 
meta:存放说明信息、说明角色依赖等信息,可留空; 
tasks:nginx安装过程成需要进行的执行的任务; 
templates:用于执行nginx安装的模板文件,一般为脚本; 
vars:本次安装定义的变量
[root@localhost ~]# tree /etc/ansible/nginx/
/etc/ansible/nginx/

    └── nginx_install

        └── vars
            └── main.yml

8 directories, 11 files

?创建nginx入口文件,用来调用nginx_install:

[root@localhost nginx]# cat nginx.yml 
- hosts: nginx
  remote_user: root
  gather_facts: True

  roles:
    - nginx_install

?创建变量:

[root@localhost nginx]# cat roles/nginx_install/vars/main.yml
NGINX_VER: 1.16.0
NGINX_USER: nginx
NGINX_PORT: 80
SOURCE_DIR: /software
NGINX_DIR: /usr/local/nginx
DATA_DIR: /data/nginx

?创建模板文件:
