1 \#!/bin/bash2 \#desc: mysql5.6的一键安装脚本3 \#安装说明: 将整个目录上传到服务器任意目录下，修改配置文件中MySQL密码后，直接执行可。4 \#测试环境: 该脚本在虚拟机上的centOS6.8下测试可行，Linux系统为标准桌面安装5

6 \#\#\#预定义变量7 \#获得当前脚本所在目录8 curr\_path=$(cd \`dirname $0\`; pwd)9 \#获得配置文件10 conf\_file=$\{curr\_path\}/install.conf11 \#安装包所在目录，为脚本当前目录的rpms下12 mysql\_rpm\_dir=$\{curr\_path\}/rpms13 \#读取配置文件，获得用户自定义的mysql密码，如果用户未指定，默认密码为root14 user\_mysql\_passwd=\`sed -e '/^\[ \]\*define\_passwd\[ \]\*=/!d;s/.\*=\[ \]\*//'$\{conf\_file\}\`15 mysql\_passwd=$\{user\_mysql\_passwd:-root\}16
