关于MySQL5.6版本使用随机密码初次登陆问题

最近在安装MySQL 5.6 版本后发现，使用空密码无法登陆。

MySQL在安装后生成了一个随机的密码，可以在 '/root/.mysql_secret’中找到。

查看随机密码

[root@node01 usr]# more /root/.mysql_secret
# The random password set for the root user at Tue Dec 10 19:17:01 2019 (local time): ebVNjLNSgNdM4Hvn

重启MySQL

service mysql restart

登陆MySQL

[root@node01 usr]# mysql -uroot -pebVNjLNSgNdM4Hvn

初次登陆后需要修改密码才可以执行SQL语句进行操作。

修改密码

mysql> set password=password('root');
Query OK, 0 rows affected (0.00 sec)

修改密码后可以正常执行SQL语句

mysql> select 1;
 
+---+
 
| 1 |
 
+---+
 
| 1 |
 
+---+
 
1 row in set (0.03 sec)
 
 
mysql>  

设置远程root访问

mysql> use mysql;  
mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";    //为root添加远程连接的能力  
mysql> flush privileges;  
mysql> exit

至此，你就可以使用Navicat等工具连接啦。
