【SaltStack】通过Master给Minion安装MySQL

一、IP信息说明

【Master】

IP: 192.168.236.100

【Minion】

IP: 192.168.236.101

二、配置SaltStack

关于SaltStack Master和Minion的安装这里不再赘述！

【配置Master】

1.新建目录

mkdir  -p  /srv/salt/iso

mkdir -p   /srv/salt/install_mysql

2.新建配置文件

(1)  /srv/top.sls

base:
   '*':
    - cpitables.*
    - install_zabbix.*
    - install_mysql.*

(2)  /srv/salt/install_mysql/install_mysql.sls

说明：该文件内，执行install_mysql.py脚本的顺序和安装mysql的顺序不能乱，因为安装mysql时需要mysql用户和mysql用户组必须存在，否则会报错！

/soft/install_mysql.py:
  file.managed:
    - unless: test -e /soft/install_mysql.py
    - source: salt://install_mysql/install_mysql.py
    - user: root
    - group: root
    - mode: 775
  cmd.run:
    - name:  /usr/bin/python /soft/install_mysql.py
    - require:
      - file: /soft/install_mysql.py

    - source: salt://iso/mysql-5.7.18.tar.gz
    - user: root
    - group: root
    - mode: 644
  cmd.run:
    - cwd: /soft
    - name: mv mysql-5.7.18.tar.gz /usr/local && cd /usr/local && tar zxf /usr/local/mysql-5.7.18.tar.gz && mv mysql-5.7.18-linux-glibc2.5-x86_64 mysql && cd mysql &&

    - unless: test -d /usr/local/mysql
    - require:
      - file: /soft/mysql-5.7.18.tar.gz


/soft/edit_mysql.py:
  file.managed:
    - unless: test -e /soft/edit_mysql.py
    - source: salt://install_mysql/edit_mysql.py
    - user: root
    - group: root
    - mode: 775
  cmd.run:
    - name:  /usr/bin/python /soft/edit_mysql.py
    - require:
      - file: /soft/edit_mysql.py

(3)  /srv/salt/install_mysql/install_mysql.py

#!/usr/bin/python

import socket
import os

content = '''
[client]    
port = 3306    
socket = /tmp/mysql.sock    

[mysqld]    
user=mysql    
port = 3306    
server_id = 1    
socket=/tmp/mysql.sock    
basedir =/usr/local/mysql    
datadir =/usr/local/mysql/data    
pid-file=/usr/local/mysql/data/mysqld.pid    
log-error=/usr/local/mysql/log/mysql-error.log  
    '''

def init_mysql():

    #修改mysql的配置文件/etc/my.cnf
    with open('/etc/my.cnf','r+') as newfile:
        newfile.write(content)
        newfile.close()

    #新建mysql用户组和mysql用户
    os.system('groupadd mysql ')
    os.system('useradd -g mysql mysql')
init_mysql()

(4)  /srv/salt/install_mysql/edit_mysql.py

#!/usr/bin/python
# coding:utf-8

import os

def edit_mysql():

    #Setting mysql env variable
    os.system("sed -i 's/PATH=$PATH:$HOME/bin/PATH=$PATH:$HOME/bin:/usr/local/mysql/bin/'  ~/.bash_profile")
    os.system('source ~/.bash_profile')


    #Settting mysql boot
    os.system('cp /usr/local/mysql/support-files/mysql.server  /etc/init.d/mysql.server')
    os.system('service mysql.server start')
    #os.system("set password for root@localhost = password('mysql')")
    #os.system('flush privileges')

edit_mysql()

(6) 将MySQ安装包mysql-5.7.18.tar.gz复制到目录/srv/salt/iso

【Minion】

在客户端新建目录soft

mkdir /soft

三、操作说明

在Master执行如下命令进行操作：

salt '*'  state.sls install_mysql.install_mysql

'*' : 表示所有可侦测到的Minion端

state.sls ：为固定用法

install_mysql ：表示install_mysql.sls文件所在的上次目录，该目录以/etc/salt/master文件中定义的目录为家目录

install_mysql : 为操作用到的sls文件

其他可能用到的命令：

检测Master与Minion的是否连接：

salt '*'  test.ping

在安装zabbix前进行验证测试：

salt '*'  state.sls install_mysql.install_mysql test=True
