Any way to trace MySqlConnection to detect reasons for slow connection

眉间皱痕 提交于 2020-01-07 02:26:07
问题 I need to find some way in C# to trace the MySqlConnection.Open() methods connection to find out why it's taking over 15 seconds just to establish the connection. I.e to see some kind of connection log to find out whats holding it up. The code below is in an otherwise empty project and I've tried disabling the firewall and changing the port. Please help I've been trying to fix this for two days now and I'm almost admitting defeat. EDIT: Also the port is 3310 instead of the 3306 mySQL default

问题 I have just installed a MySQL server (version 3.23.58) on an old RedHat7. I cannot install a more recent MySQL version because of the dependencies. I cannot update librairies on this RedHat server. However, I have a problem connecting to the database with PHP. First I used PDO but I realized that PDO was not compatible with MySQL 3.23... So I used mysql_connect() . Now I have the following error: Warning: mysql_connect(): No such file or directory in /user/local/apache/htdocs/php/database.php

问题 I'm using mysql-server 5.5 and had created a server instance. After created I try to open the instance editor and select Options File in CONFIGURATION but it says Configuration file '' can not be found.
