Binding to IP aliases and using non-standard ports

Postby JKMickelson » 23. February 2007 10:15

I have code that enables the /opt/lampp/lampp script to read the actual values in the config files for http, https, mysql, and proftpd instead of presuming the defaults. The code uses these config file values when checking the port (i.e. testport).

This allows XAMPP to co-reside with an RPM installation (apt-get, yum, etc) of httpd, mysqld, and any ftp service. This also allows XAMPP to be bound to an IP alias (using identical ports) which provides a discreet environment.

The importance of this ability is that I can now easily run two versions of Apache, MySQL, and PHP without disturbing either environment.

How do I contribute this code to XAMPP?

Thanks,
Jonathan

The proposed changes...

Postby JKMickelson » 23. February 2007 22:20

These are the proposed changes to the lampp script:

After the copyright notice, add the line
Code: Select all
. /opt/lampp/checkport

Replace these individual lines of code
Code: Select all
if testport 80
if testport 443
if testport 3306
if testport 21

with these lines respectively
Code: Select all
if checkport HTTP
if checkport HTTPS
if checkport MYSQL
if checkport FTP


The checkport script is placed in the /opt/lampp directory.

Done!

This is the checkport script

Postby JKMickelson » 24. February 2007 00:42

This is the checkport script.

Code: Select all
#!/bin/bash
# checkport
# description: checks if the port is in use for the service specified.
#              uses actual config file values, both IP address and port number.
#
# usage: checkport [HTTP | HTTPS | MYSQL | FTP]
#
# getport
# description: gets the IP address and port number for the service specified.
#              uses actual config file values, both IP address and port number.
#
# usage: getport [HTTP | HTTPS | MYSQL | FTP]

Dear Jonathan!

Looks great!!! I think I've to include it into the next XAMPP release. But I'll move checkport to /opt/lampp/bin to keep the /opt/lampp directory clean.

Thanks a million!!! Do you've more ideas? ;)

Many greetings
Oswald
