Ansible playbook 实战

一、基础准备

主机	外网	内网	部署服务
m01	192.168.15.161	172.16.1.161	ansible
lb01	192.168.15.105	172.16.1.105	nginx
web01		172.16.1.107	nginx+php+rpcbind
web02		172.16.1.108	nginx+php+rpcbind
db01		172.16.1.151	mariadb
nfs		172.16.1.131	nfs+rpcbind+inotify+sersync
backup		172.16.1.141	rsync

1.安装ansible

[root@m01 ~]# yum install -y ansible

2.配置ansible

[root@m01 ~]# vim /etc/ansible/ansible.cfg
host_key_checking = False
log_path = /var/log/ansible.log

3.配置主机清单

[root@m01 ~]# cat /etc/ansible/hosts 
[web_group] 
web01 ansible_ssh_pass='123'
web02 ansible_ssh_pass='123'

[nfs_group]
nfs ansible_ssh_pass='123'


[slb]
lb01 ansible_ssh_pass='123 '


[db_group]
db01 ansible_ssh_pass='123'

[backup_group]
backup ansible_ssh_pass='123'

[nginx_group:children]
web_group
slb


[nfs_server:children]
web_group
nfs_group

4.配置hosts

[root@m01 ~]# vim /etc/hosts
72.16.1.107 web01

172.16.1.108 web02

172.16.1.131 nfs

172.16.1.141 backup

172.16.1.151 db01

172.16.1.105 lb01

# 测试连接
[root@m01 ~]# ansible all -m ping

5.创建配置文件统一目录

[root@m01 ~]# mkdir mm     --文件目录
[root@m01 ~]# mkdir packege  -- 站点目录 需要压缩的包

二、编写剧本实例

1.第一部分：所有服务器优化

[root@m01 ~]# cat lnmp.yml 
- hosts: all
  tasks:
    - name: stop selinux
      selinux:
        state: disabled

    - name: stop firewalld
      systemd:
        name: firewalld
        state: stopped
        enabled: no

    - name: install unzip
      yum:
        name: unzip
        state: present
    - name: create www group
      group:
        name: www
        gid: 666

    - name: create www user
      user: 
        name: www
        uid: 666
        group: www
        shell: /sbin/nologin
        create_home: no

 # 检查一下
 [root@m01 ~]# ansible-playbook --syntax-check lnmp.yml

2.第二部分：nginx部分

1.安装并部署nginx - 思路

1、安装方式
#源码包安装方式
1.上传包
2.解压
unarchive
3.生成

#官方源方式
1.配置官方源
2.推送官方源
copy
3.安装nginx
yum

#rpm包的方式

# 4.准备站点配置文件
[root@m01 mm]# cat linux12.wp.com.conf 
server {
    listen 80;
    server_name linux12.wp.com;
    root /mm/wordpress;

    location / {
        index index.php;
    }

    location ~* \.php$ {
        fastcgi_pass 127.0.0.1:9000;
	fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
	include fastcgi_params;
    }

}
# 5.准备负载均衡的配置文件
[root@m01 mm]# cat proxy.conf 
upstream web {

# 7. 准备wordpress连接数据库配置
[root@web01 wordpress]# scp -r wp-config.php 192.168.15.108:/mm/wordpress/
[root@web01 wordpress]# vim mm/wp-config.php
[root@web01 wordpress]# cat wp-config.php 
// ** MySQL 设置 - 具体信息来自您正在使用的主机 ** //
/** WordPress数据库的名称 */
define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */
define('DB_USER', 'wp');

/** MySQL数据库密码 */
define('DB_PASSWORD', '123');

/** MySQL主机 */
define('DB_HOST', '172.16.1.151');

/** 创建数据表时默认的文字编码 */
define('DB_CHARSET', 'utf8mb4');

/** 数据库整理类型。如不确定请勿更改 */
define('DB_COLLATE', '');

3、编写nginx剧本

[root@m01 ~]# cat lnmp1.yml 
- hosts: nginx_group
  tasks:
    - name: copy nginx.repo
      copy:
        src: /root/mm/nginx.repo
        dest: /etc/yum.repos.d/
    
    - name: install nginx server
      yum:

        name: nginx
        state: present

    - name: config nginx server
      copy:
        src: /root/mm/nginx.repo

    - name: mkdir mm
      file:
        path: /mm
        state: directory

    - name: confog wordpress mm
      unarchive:
        src: /root/package/wordpress.tar.gz
        dest: /mm/
    - name: grant mm dir
      file:
        path: /mm
        owner: www
        group: www
        recurse: yes
    - name : start web nginx server
      systemd:
        name: nginx

博客报错总结

ansible playbook 使用时间变量 ansible playbook when_linux

# 注意这个wp-config.php 在哪里  
 scp -r /mm/wordpress/wp-config.php 172.16.1.107: /mm/wordpress/

6.依次执行实现ansible一键安装

# 输入 win +r drivers

#1.先在 web01,web02,lb01,nfs,backup机器执行 

[root@nginx ~]# yum remove php-mysql-5.4 php php-fpm php-common   
### 发生报错执行这个命令，切记切记

# 2.验证ansible剧本
[root@m01 ~]# ansible-playbook --syntax-check lnmp0.yml
[root@m01 ~]# ansible-playbook --syntax-check lnmp1.yml
[root@m01 ~]# ansible-playbook --syntax-check lnmp2.yml
[root@m01 ~]# ansible-playbook --syntax-check lnmp3.yml
[root@m01 ~]# ansible-playbook --syntax-check lnmp4.yml
[root@m01 ~]# ansible-playbook --syntax-check lnmp5.yml

# 3.实现ansible分开依次安装
[root@m01 ~]# ansible-playbook  lnmp0.yml
[root@m01 ~]# ansible-playbook  lnmp1.yml
[root@m01 ~]# ansible-playbook  lnmp2.yml
[root@m01 ~]# ansible-playbook  lnmp3.yml

# 1.验证ansible剧本
[root@m01 ~]# ansible-playbook --syntax-check mmlnmp.yml 

# 3.一键 ansible安装
[root@m01 ~]# ansible-playbook  mmlnmp.yml

6.扩展web服务器

1.将新机器添加到ansible 主机清单

[root@m01 ~]# cat /etc/ansible/hosts 
[web_group] 
web01 ansible_ssh_pass='123'
web02 ansible_ssh_pass='123'
web03 ansible_ssh_pass='123'

[root@m01 ~]# cat /etc/hosts

172.16.1.107 web01

172.16.1.108 web02

172.16.1.109 web03

2.创建web扩展文件

[root@m01 ~]# cp mm/proxy.conf mm/new.proxy.conf

[root@m01 ~]# cat mm/new.proxy.conf
upstream web {
    server 172.16.1.107;
    server 172.16.1.108;
    server 172.16.1.109;
}

server {
    listen 80;
    server_name linux12.wp.com;
    

    location / {
	proxy_pass http://web;
	include proxy_params;
    } 
}

3. 编写剧本

[root@m01 ~]# cat lnmp.yml 
- hosts: web03
  tasks:
    - name: stop selinux
      selinux:
        state: disabled
