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

    本机ip: 192.168.1.248

    远程ip: 192.168.1.249

    mysql服务器配置

    # 1.更改配置文件
    
    #因为远程mysql服务器,设置只监听本地的端口,更改mysql配置文件,注释掉下面的一行。打开远程服务器的配置文件.
    sudo vi /etc/mysql/my.cnf # 注释下面一行。
    # bind-address = 127.0.0.1
    # 如果没注释上面的一行,客户端连接时,会出现如下错误。
    ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.249' (111)
    
    # 2. 打开mysql服务
    sudo service /etc/init.d/mysql start
    
    # 3. 配置mysql服务器
    qt@tony:~/Desktop$ mysql -u root -p 
    Enter password:
