5:初始化数据目录(初始化过程中会产生一个随机密码，记得记录一下，等下登录要用)
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/opt/mysql
6:启动mysq服务
拷贝启动脚本到init中
cp -rf /usr/local/mysql/support-files/mysql.server /etc/init.d/
修改启动脚本中的mysql安装路径和数据路径
启动服务
/etc/init.d/mysql.server start
停止服务
/etc/init.d/mysql.server stop
重启
/etc/init.d/mysql.server restart
7:登录后修改临时密码
set password for root@localhost=password(‘123456‘);
