MySQL 5.6 关于登录的初始化设置

 最近研究一下MySQL 5.6 版本发现安装后，使用空密码没法登录

安装的过程当中有这样的一句话：

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !

You will find that password in '/root/.mysql_secret'.

You must change that password on your first connect,

no other statement but 'SET PASSWORD' will be accepted.

See the manual for the semantics of the 'password expired' flag.

 大概意思就是 一个随机的密码已经生成 能够在  '/root/.mysql_secret'. 中找到

第一次链接必须变动密码 且只能使用 'SET PASSWORD' 命令

在user 表中新增长了'password expired'  列，也就是密码过时

 

咱们来启动mysql 而后登录

service mysql start

 

mysql -uroot -pvssAWF0O

 

#密码是在 more .mysql_secret  里面记录

# The random password set for the root user at Mon Mar 25 11:13:11 2013 (local time): vssAWF0O

Warning: Using a password on the command line interface can be insecure.
