ubuntu mysql 遠程鏈接

最近須要遠程鏈接mysql服務器，先進行簡單的測試，過程記錄於此。

參考連接：

　　http://stackoverflow.com/questions/1420839/cant-connect-to-mysql-server-error-111

本機ip： 192.168.1.248

遠程ip： 192.168.1.249

mysql服務器配置

# 1.更改配置文件

#由於遠程mysql服務器,設置只監聽本地的端口,更改mysql配置文件,註釋掉下面的一行。打開遠程服務器的配置文件.
sudo vi /etc/mysql/my.cnf # 註釋下面一行。
# bind-address = 127.0.0.1
# 若是沒註釋上面的一行，客戶端鏈接時，會出現以下錯誤。
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.249' (111)

# 2. 打開mysql服務
sudo service /etc/init.d/mysql start

# 3. 配置mysql服務器
qt@tony:~/Desktop$ mysql -u root -p
