System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 – all working fine.
After installing mysqli using the php package, Apache won’t start anymore. There is no error message in the log.
What I have tried:
- Make sure Windows PATH points to libmysql.dll: Yes, done.
- Make sure extension_dir points to the right point: Yes. Other extensions load fine.
- Try without mysqli: Yes, Apache loads fine then.
- Try without mysql: Yes, does not help.
- Test mysql itself: Restarts server!
- Overwrite libmysql: Yes, does not help.
It seems to me that there is some general problem with MySql, but the DB server seems to be running fine.
I’m really out of ideas of things I could try, so I’m desperate for any hints or tricks.
The problem was a hidden second mysql installation. Boy, did that take time to figure..
