Ansible 一键配置安装Keepalived+Nginx作为前端,httpd+php作为后端



    一、环境:
      

 Ansible控制机:172.16.0.6        
        Ansible nginx:172.16.0.{2|4}
        Ansible Keepalived: 172.16.0.{2|4}
        Ansible httpd: 172.16.0.{128|129}
        Keepalived IP:192.168.220.5/32

  

除控制机全部采用Linux Cento7,外网统一192.168.220.0/27
一般生产机我们会把Yum仓库指向自己搭建的,这里我们使用ail以及163的Yum仓库
  • {2|4}使用ail仓库源

root@centos7 nginx]# cat /etc/yum.repos.d/ail.repo 
	[centos7]
	name=centeros7 base
	baseurl=http://mirrors.aliyun.com/centos/7/os/x86_64/
	gpgcheck=0
	[epel]
	name=epel base
	baseurl=http://mirrors.aliyun.com/epel/7/x86_64
	gpgcheck=0
  • {128|129}使用163仓库源,地址:http://mirrors.163.com/.help/CentOS7-Base-163.repo

[root@Centos7 yum.repos.d]# cat /etc/yum.repos.d/CentOS7-Base-163.repo 
	# CentOS-Base.repo
	...
	[base]
	name=CentOS-$releasever - Base - 163.com	
	#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
	baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/
	gpgcheck=1
	gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

	...
二、Ansible控制机目录结构:
[root@HA2 ansible]# tree .
        .          
        ├── ansible.cfg					#Ansible配置文件
	├── hosts					#Ansible主机清单
	├── roles					#Ansible 角色目录

	│       └── vars
	│           └── main.yml
	├── service.retry
	└── service.yml					#定义主机以及远程用户
三、问件分析:
  • ansible.cfg:这里使用的是默认

  • hosts:

[root@HA2 ansible]# cat hosts[nginx]			
#定义nginx主机清单列表,下面mb,prioroty为变量
	172.16.0.2   mb=MASTER prioroty=100  	
	172.16.0.4   mb=BACKUP prioroty=98

	[httpd]		#定义httpd主机清单,hname为变量
	172.16.0.128 hname=httpd128	172.16.0.129 hname=httpd129

	[dbserver]	#定义dbserver主机清单,这里我没有去安装
	172.16.0.5 hname=dbserver
  • server.yml:

[root@HA2 ansible]# cat service.yml 
	- hosts: all 			#定义hosts范围	  
	remote_user: root		#定义远程用户
	  roles:			#使用roles
	  - nginx			#nginx列表,就是roles目录下的nginx目录	  
	  - httpd			#httpd列表,就是roles目录下的httpd目录	  
	  - keepalived			#keepalived列表,就是roles目录下的keepalived目录
[root@HA2 ansible]# cat service.retry 	#执行后自动生成,无需理会
	172.16.0.2
	172.16.0.4
  • roles:

[root@HA2 ansible]# ls roles/			#每一个文件目录名称为一个角色
	httpd  keepalived  memcached  nginx
  • nginx
    每个角色结构如下,上面解释过就不介绍,下面介绍配置文件

[root@HA2 ansible]# tree roles/nginx/
