PHP-Apache-MySQL服务器| 无法连接到主机

Question

I'm facing this problem since yesterday evening. I have been now over 6 hours on Google, trying to figure out what the solution could be.

I have tried this , setting the timeout on all php.ini files to 300 or unlimited, I have tried setting the buffer of MySQL higher, tried to restart both Apache and MySQL server, ...

Problem: What I'm trying to do, where the error occurs, is to execute a SOAP-command (command is correct) $this -> soap -> executeCommand(new SoapParam($command, 'command')); , which results in:

"Could not connect to host" --> if I set define('DB_HOST', '127.0.0.1'); or

Problem 2:

 //Warning: mysqli::mysqli() [function.mysqli-mysqli]: (HY000/2003): Can't connect to MySQL server on 'blacktempel.dyndns-home.com' (10060) in C:\Users\NAME\Desktop\Server_09122014\Apache\_Server\htdocs\SOAPRegistration.php on line 109
 //Warning: mysqli::close() [function.mysqli-close]: Couldn't fetch mysqli in C:\Users\NAME\Desktop\Server_09122014\Apache\_Server\htdocs\SOAPRegistration.php on line 154


$this -> db = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME, DB_PORT); //Line 109
$this -> db -> close(); //Line 154

"Database connection failed: Can't connect to MySQL server on 'blacktempel.dyndns-home.com' (10060)" --> if I set define('DB_HOST', 'blacktempel.dyndns-home.com'); .

My firewall is not the problem, I have checked this multiple times.

My hosts file contains this:

#       127.0.0.1       localhost
#       ::1             localhost
        MyExternalIp    blacktempel.dyndns-home.com

SOAP:

define('SOAP_IP', '127.0.0.1');
define('SOAP_PORT', '7878');

MySQL is running on port 3306 and listening. My other defines, such as DB_USER , DB_PASS , are correct.

Q: Why won't it work ? What could be wrong ? Is there anything I could possibly have missed ?

Answer 1

Fixed the issue.

The SOAP problem was caused by a setting in the config file of the program accessed by SOAP.
