基于ansible Role实现批量部署lamp平台

1、配置好 Inventory 文件  
# /etc/ansible/hosts
  

  
node2.example.com
  
node3.example.com
  

  

  
director1.example.com
  
director2.example.com
  

  
2、创建对应的目录树
  
# 执行 tree /root/lamp/roles 查看目录树
  
/root/lamp/roles
  
|-- common
  
|   |-- default
  
|   |-- files
  
|   |   `-- hosts
  
|   |-- handlers
  
|   |-- meta
  
|   |-- tasks
  
|   |   `-- main.yml
  
|   |-- templates
  
|   `-- vars
  
|-- db
  
|   |-- default
  
|   |-- files
  
|   |   `-- my.cnf
  
|   |-- handlers
  
|   |   `-- main.yml
  
|   |-- meta
  
|   |-- tasks
  
|   |   `-- main.yml
  
|   |-- templates
  
|   `-- vars
  
|-- db.yml
  
|-- php
  
|   |-- default
  
|   |-- files
  
|   |   `-- php.ini
  
|   |-- handlers
  
|   |-- meta
  
|   |-- tasks
  
|   |   `-- main.yml
  
|   |-- templates
  
|   `-- vars
  
|-- site.yml
  
|-- web
  
|   |-- default
  
|   |-- files
  
|   |   `-- httpd.conf
  
|   |-- handlers
  
|   |   `-- main.yml
  
|   |-- meta
  
|   |-- tasks
  
|   |   `-- main.yml
  
|   |-- templates
  
|   `-- vars
  
`-- web.yml
  

  

  

  
3、各个文件的内容
  
# 当前所在目录 /root/lamp/roles
  
# cat db.yml
  
- name: mysqld servise
  
remote_user: root
  
hosts: mysql
  
roles:
  
    - common
  
    - db
  

  
# cat web.yml
  
- name: wed servise
  
remote_user: root
  
hosts: webhosts
  
roles:
  
    - common
  
    - php
  
    - web
  

  
# cat common/files/hosts
  
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
  
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  
172.16.10.22 node2.example.com
  
172.16.10.33 node3.example.com
  
172.16.0.50 director1.example.com
  
172.16.0.51 director2.example.com
  

  
# cat common/tasks/main.yml
  
- name: Configure hostname resolve
  
copy: src=hosts dest=/etc/hosts
  

  
# cat php/tasks/main.yml
  
- name: install php
  
yum: name=php state=present
  
- name: configuration php
  
copy: src=php.ini dest=/etc/php.ini
  

  
# cat web/tasks/main.yml
  
- name: install httpd
  
yum: name=httpd state=present
  
- name: configuration httpd
  
copy: src=httpd.conf dest=/etc/httpd/conf/httpd.conf
  
notify:
  
    - restart httpd
  
- name: service httpd start
  
service: name=httpd enabled=no state=started
  

  
# cat web/handlers/main.yml
  
- name: restart httpd
  
service: name=httpd state=restarted
  

  
# cat db/tasks/main.yml
  
- name: install mysql
  
yum: name=mysql state=present
  
- name: install mysql-server
  
yum: name=mysql-server state=present
  
- name: configuration mysqld
  
copy: src=my.cnf dest=/etc/my.cnf
  
notify:
  
    - restart mysqld
  
- name: service mysqld start
  
service: name=mysqld enabled=no state=started
  

  
# cat db/handlers/main.yml
  
- name: restart mysqld
  
service: name=mysqld state=restarted
  

  
4、开始批量部署
