Ubuntu ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)

配置远程连接mysql

MySQL>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION;

MySQL>FLUSH PRIVILEGES;

远程连接mysql时

mysql -h127.0.0.1 -u root  -p

报错:

ERROR 2003 (HY000): Can’t connect to MySQL server on ‘127.0.0.1’ (111)

解决方法：

sudo vi /etc/mysql/my.cnf

注释掉下面这行：
#bind-address           = 127.0.0.1

sudo /etc/init.d/mysql restart
