mysql安装脚本

2、执行 sh mysql_install-5.7.13.sh ${MYSQL_PORT_NO} 脚本
sh mysql_install-5.7.13.sh 3306
Mysql安装时，会打印出root账户的临时密码，记下临时密码
3、登录mysql并修改临时密码,并给root用户在其他机器可以登录的权限，在安装完成后再取消该权限。命令如下：
mysql -uroot -p ALTER USER 'root'@'localhost' IDENTIFIED BY 'root'; use mysql update user set Host = "%" where User = "root";
至此mysql安装完成
