My guess is that you’re trying to install a LAMP server, and downloaded the infamous XAMP package. That’s not necessary, openSUSE has it all on board:
Start Yast - Software - Software manager
View - Patterns
Scroll down to the LAMP pattern, check the box left to it, all packages needed for a LAMP server are being selected for install
Also select phpMyAdmin for install.
Accept, run the install.
Close Yast
Start Yast, it now has a new module in Network services: HTTP server, start it
Have the firewall open needed port(s)
Set the webserver to start at boot\
OK
When using all defaults the webroot is /srv/www/htdocs, browsing http://localhost should give “It works!”
The next thing is to setup MYSQL, it needs at least a root (not the same as the linux super user) user and password, phpMyAdmin will not work passwordless.
