Playbooks 是 Ansible的配置、部署、编排语言。他们可以被描述为一个需要希望远程主机执行命令的方案,或者一组IT程序运行的命令集合。
言简意赅,Playbooks就是我们现阶段操作自动化的解决方案。通过Playbooks的编排,我们可以按需定制各种自动化操作。
本次我们介绍LAMP环境自动化部署,将其拆分为以下几个阶段:
批量编译安装lamp(apache+php及扩展);
初始化配置(自动加载php模块,修改mpm、日志轮储等);
手动按需修改站点文件;
1
配置思路
ansible-playbook配置思路,如下:
通过vars中的main.yml配置变量,主要为源码存放目录及安装目录;
通过tasks中的copy.yml将源码文件传输到异地服务器上源码存放目录;
通过tasks中的install.yml调用模板lamp_install.sh,将lamp安装到变量中定义的安装目录;
通过tasks中的main.yml调用copy模块和install模块;
通过lamp.yml调用剧本(playbook):lamp_install实现自动化部署;
2
目录结构
我们按playbook组织目录结构,其中:
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:角色定义可留空;
tasks:lamp安装过程成需要进行的执行的任务;
templates:用于执行lamp安装的模板文件,一般为脚本;
vars:本次安装定义的变量
[root@test ansible]# cd /etc/ansible/
[root@test ansible]# mkdir -p roles/lamp_install/{files,handlers,meta,tasks,templates,vars}
[root@test ansible]# tree /etc/ansible

具体实现
1.创建lamp角色文件,用于调用lamp_install
[root@test ansible]# vim lamp.yml
- hosts: test
remote_user: root
gather_facts: False
roles:
- lamp_install
2.创建变量文件
变量文件作用是提取变量,以适应定义化部署需求。
[root@test ansible]# cd /etc/ansible/roles/lamp_install/vars
[root@test ansible]#vim main.yml
#源码存放目录
source_dir: /home/ap/src/lamp/
#源码安装目录
install_dir: /home/ap/
3.创建任务文件
任务文件的作用是将各种源码同步到远程机器上,做安装前的准备工作。
[root@test ansible]# cd /etc/ansible/roles/mysql_install/tasks
[root@test ansible]# vim copy.yml
#复制php组件至目标服务器
- name: copy php dir to client
copy: src=php dest={{source_dir}} owner=root group=root
#复制apache组件至目标服务器
- name: copy apache dir to client
copy: src=apache dest={{source_dir}} owner=root group=root
#复制memcached组件至目标服务器
- name: copy memcached dir to client
copy: src=memcached dest={{source_dir}} owner=root group=root
#复制模板文件至目标服务器
- name: copy lamp script to client
template: src=lamp_install.sh dest={{source_dir}} owner=root group=root mode=0775
[root@test ansible]# vim install.yml
#执行模板文件进行安装
- name: install lamp
shell: bash {{source_dir}}/lamp_install.sh
[root@test ansible]# vim main.yml
#引用copy、install模块
- include: copy.yml
- include: install.yml
注意:
copy模块复制目录,需要加上递归参数recurse;
copy模块复制目录,没有目录将会在目标服务器上创建;
copy模块复制文件到目标服务器的某一个目录下,需要在dest参数上加上/home/ap/src/lamp/,而不是/home/ap/lamp,否则ansible将会把文件复制为lamp,而不是放在lamp目录下;
4.编写模板脚本
模板脚本的作用是安装部署并进行相关组件的配置,主要如下:
安装apache及相关组件
安装memcached、magent
安装php及相关扩展mogo、memcached、memcache、soap、gd、mbstring、exif、eaccelerator,并添加至php.ini;在apache中引用php
修改http.conf,包括添加rewrite模块,修改AllowOverride等
修改http-mpm.conf
添加rewrite.conf
添加站点配置文件
