10.ansible 利用playbook部署LAMP环境

基本文件目录如下:
httpd所需软件:httpd mariadb mariadb-server php  php-mysql   gd    php-gd
[root@ansible role]# ls
httpd          site_nginx.retry  site.retry
mariadb  php-apache  site_apache.yaml 

[root@ansible role]# cat site_apache.yaml
---
- hosts: group
  roles:
  - httpd
  - php-apache
  - mariadb

1.httpd目录
[root@ansible role]# cd httpd/
[root@ansible httpd]# ls
files  handlers  tasks  templates  vars

 

[root@ansible httpd]# cat files/index.html
hello world
[root@ansible httpd]# cat handlers/main.yaml
---
- name: reload httpd.service
  service: name=httpd state=reloaded
[root@ansible httpd]# cat tasks/main.yaml
---
- name: install httpd
  yum: name=httpd state=present

- name: copy httpd configure file
  template: src=httpd.conf.j2 dest=/etc/httpd/conf/httpd.conf
  notify: reload httpd.service

- name: copy index.html
  copy: src=index.html dest=/var/www/html/index.html

- name: start and enable httpd
  service: name=httpd state=started enabled=yes

[root@ansible httpd]# ls templates/

在httpd.conf.j2中定义变量

Listen {{ httpd_port }}

[root@ansible httpd]# cat vars/main.yaml
 httpd_port: 80

2.mariadb目录
[root@ansible role]# cd mariadb/
[root@ansible mariadb]# ls

[root@ansible mariadb]# cat handlers/main.yaml
---
- name: restart mariadb.service
  service: name=mariadb state=restarted

[root@ansible mariadb]# cat handlers/main.yaml
---
- name: restart mariadb.service
  service: name=mariadb state=restarted
[root@ansible mariadb]# cat tasks/main.yaml

- name: install mariadb
  yum: name={{ item }} state=present
  with_items:

- name: copy mariadb configure file
  template: src=my.cnf.j2 dest=/etc/
  notify: restart mariadb.service

- name: start and enable mariadb

[root@ansible mariadb]# ls templates/
my.cnf.j2

[root@ansible mariadb]# cat vars/main.yaml
