Ansible Installing Nginx

* Idea: First on a machine to compile and install the Nginx, packaging, and then use Ansible to the issued

1./usr/local/nginx/is an nginx file that has been compiled and installed, and the startup scripts and configuration files are configured.

2.cd/usr/local #进入上一级目录

3.tar CZVF nginx.tar.gz Nginx #将目录打包

4.cd/etc/ansible entering the Ansible profile directory

5.mkdir Nginx_install Create a Nginx_install directory for easy Management

6.CD Nginx_install

7.mkdir-p Roles/{common,install}/{handlers,files,meta,tasks,templates,vars}

There are several directories under each role, handlers the following is the action to take when a change occurs, usually with a change in the configuration file, to restart the service. Files for the installation of some documents, meta for the description of information, the role depends on the information, tasks inside is the core configuration file, templates usually save some configuration files, startup scripts and other template files, according to different machine configuration, issued a different configuration file. Variables defined under VARs

8.cd/etc/ansible/nginx_install/roles/common/tasks

* Define Common/tasks File

9.vim main.yml #定义common的tasks, Nginx needs some dependent packages. The content is as follows

---

Nginx_user:www

Nginx_port:80 #可不写, not to use

Nginx_basedir:/usr/local/nginx #定义客户端解压到哪个目录下去

* Define the Install/tasks file, copy the relevant files to the specified directory

14.vim tasks/copy.yml

-Name:copy Nginx Config #引用的变量在vars中已经定义了

template:src=nginx.conf dest={{nginx_basedir}}/conf/owner=root group=root mode=0644

15.vim tasks/install.yml #定义建立用户, start the service, delete the compressed package

-Name:create Nginx User #www用户是nginx的配置文件中定义的, there will be no error, so to add users

-Name:start Nginx Service

Service:name=nginx state=started

-Name:add Boot Start Nginx Service
