MySQL5.6一键部署

# 快速部署单节点MySQL脚本
# 执行方式：将MySQL包，my3302.cnf配置文件，dbtool脚本文件放到一个目录下。然后按照脚本执行就可以。配置文件提前修改好。文章最后附上my.cnf配置文件内容

# 环境：

# Linux：CentOS release 6.6 (Final)
# mysql: Percona-Server-5.6.32-rel78.0-Linux.x86_64.ssl098e.tar.gz # 下载地址 : https://www.percona.com/downloads/Percona-Server-5.6/LATEST/

# 简介：脚本中每一步都定义的函数，通过：./dbtool port cmd 格式 来调用。port：MySQL端口；cmd 每个函数的调用命令简写。例如：./dbtool 3002 sd 启动mysql.
#　　　大家可以根据需要在下面追加函数，定义功能。比如：mysql的启动、停止、登录。
#　　　该脚本提供一种思路，大家可以自己扩展

# 脚本名：dbtool

#!/bin/sh
# 
PORT=$1
Instance_Name="inst01"    #实例名：多实例时目录层的区分标志
CMD="$2"
DB_DIR="/data/mysql"    # MySQL相关目录文件，本脚本为了方便都放一起了;data和log可以放到单独的分区里
Current_dir=`pwd`
