Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

環境Ubuntu14.04 mysql5.5

這個錯誤是我用mysql_real_connect()函數的時候，傳回的錯誤列印出來的。

可以先看這個篇如果解決就可以了：

如果不行可以把繼續往下試：

mysql_real_connect(connect, “localhost”, g_db_username, g_db_password, g_dbname, 0, NULL, 0);

改為：

mysql_real_connect(connect, “127.0.0.1”, g_db_username, g_db_password, g_dbname, 0, NULL, 0);
