mysql 5.6 安装后无法登录
安装完mysql之后,mysql没有生成具有空密码的root。
而是生成一个/root/.mysql_secret 文件 。
这个文件中有root密码,mysql安装时自动生成的。
[root@localhost ~]# cat /root/.mysql_secret
# The random password set for the root user at Thu Jun 19 03:45:15 2014 (local time): wb3x93cF6PoT9RfI
# The random password set for the root user at Thu Jun 19 22:44:36 2014 (local time): JbuxUpBzSJ20UTcQ
# The random password set for the root user at Thu Jun 19 23:18:57 2014 (local time): SY2pf_tC3v4YhH1x
这里选取最近时间生成的随机密码 。
用户第一次登录之后 需要更改密码
[root@localhost mysql]# mysql -u root -p
Enter password:

mysql> select * from mysql.user \G ;

直接使用 set password=password("") ;
我这里将密码设置为空了。
