ubuntu下面navicat连接本地数据库出现2003 - Can't connect to MySQL server on 'localhost'(10061 Unknown errort;)

现在mysql交互模式下输入：

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '12345' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

---------------------------------------------------------------------------------------------------------------------------------------------------

/etc/mysql/mysql.conf.d下修改文件gedit mysqld.cnf

注释掉这句话：

#bind-address      = 127.0.0.1

---------------------------------------------------------------------------------------------------------------------------------------------------

/etc/init.d/mysql restart

---------------------------------------------------------------------------------------------------------------------------------------------------

终端测试：

mysql -h localhost -u root -p12345

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

最终navicat配置如下，注意端口不要写错，我一开始查了很久最后发现把端口3306误写成3006了。
