How to reinstall a LAMP server?

Question

I want to reinstall the whole LAMP server under Debian Lenny. This means, using 'apt-get remove' is not enough, I want to remove completely all components, and start again.

I tried but files are always there so I can't make a new configuration for everything. What can I do?

Thanks!

If you just want to do the configuration over again, you can use dpkg-reconfigure [packagename] to re-run the initial setup scripts.

To completely start over, you'll need to purge all of the previous packages. I am not sure that purging Debian's mysql packages will delete the database data itself though, you may need to remove the folder with the mysql database files manually after purging the packages if you don't want to keep the data.

sandeep's "or" command should read apt-get install --reinstall ... but even then it won't do what you want since the --reinstall option will "upgrade" from the existing configuration.
