用navicat链接不上ubuntu中的mysql服务器

错误现象

2003- cant connect to mysql server on …..10061

解决方法

root@liulianjiang-virtual-machine:/usr/bin# mysql -uroot -p

Enter password:

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 8

Server version: 5.7.17-0ubuntu0.16.04.1 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> grant all privileges on *.* to root@"%" identified by "root";

Query OK, 0 rows affected, 1 warning (0.03 sec)

 

mysql> exit

root@liulianjiang-virtual-machine:/etc/mysql# grep -R address *

mysql.conf.d/mysqld.cnf:bind-address        = 127.0.0.1

root@liulianjiang-virtual-machine:/etc/mysql# vi mysql.conf.d/mysqld.cnf

bind-address = 127.0.0.1

这条语句显示的绑定了本地IP地址，以至于增加权限也无济于事。我尝试着屏蔽它，使他成为这样"#bind-address = 127.0.0.1"。

root@liulianjiang-virtual-machine:/etc/mysql# sudo /etc/init.d/mysql restart

 

搞定
