Ansible 部署源码nginx
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
[ ~]# tree /etc/ansible/nginx/ /etc/ansible/nginx/ ├── nginx.yml └── roles └── nginx_install ├── files │?? └── nginx-1.16.0.tar.gz ├── handlers ├── meta ├── tasks │?? ├── copy.yml │?? ├── install.yml │?? ├── main.yml │?? └── prepare.yml ├── templates │?? ├── fastcgi_params │?? ├── nginx.conf │?? ├── nginx.service │?? └── server.conf └── vars └── main.yml 8 directories, 11 files
?创建nginx入口文件,用来调用nginx_install:
[ nginx]# cat nginx.yml - hosts: nginx remote_user: root gather_facts: True roles: - nginx_install
?创建变量:
[ 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:
nginx主配置文件nginx.conf
