shell脚本自动化部署mysql

一、shell脚本自动部署mysql

#!/bin/env bash

#注意：
#(1)把安装包放入/root/my下面，脚本也放入/root/my，脚本名称设置为setup.sh，脚本名别带上mysql字样，否则第一步的杀死进程会导致脚本终端
#(2)执行脚本方式为：bash -x /root/my/setup.sh &> /root/setup.sh
#(3)centos版本为CentOS Linux release 7.9.2009 (Core)


exedir=/root/my
log=/root/mysqlresult.log
exe=$exedir/`ls -l -crt *tar*| awk '{print $9 }'`


function kill()
{
ps -ef | grep mysql|awk -F" " '{print $2}'|xargs kill -9
}



#检查是否安装mariadb,如果安装执行删除
function mariadb()
{
	echo

	 	echo "已删除mariadb"
	else 
		echo "不存在mariadb"
	fi
	echo "------------------------"
        echo
}

function mysqlfile()

		echo "已删除mysql用户和用户组并重新建立组！"
		
	else

		echo "不存在mysql用户和用户组，重新建立完成！"
	fi
	echo "------------------------"
        echo
}
