Navicat 连接不上 Ubuntu 中的 MySQL 服务器，提示:2003- cant connect to mysql server on …..(10061)

解决方法

root@linuxidc.com:/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@linuxidc.com:/etc/mysql# grep -R address *
mysql.conf.d/mysqld.cnf:bind-address= 127.0.0.1
 
root@linuxidc.com:/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@linuxidc.com:/etc/mysql# sudo /etc/init.d/mysql restart

OK，问题解决。
