篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Ansible 部署源码nginx相关的知识，希望对你有一定的参考价值。
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/

└── roles

?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：
