5、拷贝启动文件，并授权
1、cp support-files/mysql.server /etc/init.d/mysqld 2、chmod 755 /etc/init.d/mysqld
6 、启动数据库
/etc/init.d/mysqld start
三、更改初始化生成的数据库密码注：由于5.7版本会初始化设置密码，需要自己修改，跟之前的数据库版本更改方式不一样。
完整的更改MySQL密码的方式如下：
vim /etc/my.cnf 加入skip-grant-tables，免密码登录数据库
注：我这里注释掉是改完之后再演示的。
重启MySQL数据库
[root@lnmp ~]# /etc/init.d/mysqld restart Shutting down MySQL.. SUCCESS! Starting MySQL. SUCCESS!
登录数据，修改密码即可，注5.7的password字段改为authentication_string
