Mysql綠色版安裝

 適用於綠色版Mysql(編譯安裝後的Mysql)向其餘機器複製安裝,將腳本放在mysql目錄中執行便可安裝

#!/bin/bash
mysqluser=mysql
mysqldata=/data/mysql
mysqldir=$(cd `dirname $0`; pwd)



path=$(cd `dirname $0`; pwd)
#添加mysql用戶
/usr/sbin/useradd $mysqluser -s /sbin/nologin
if [ ! -d $mysqldata ];then
	mkdir -p $mysqldata/data
	mkdir -p $mysqldata/logs
fi
chown $mysqluser:$mysqluser $mysqldata -R
chown $mysqluser:$mysqluser $mysqldir -R
#編輯配置文件
