Ubuntu – How to remove the LAMP stack so I can start over

lampserveruninstall

I'd like to start over with my webserver and I'd like to reinstall all the LAMP packages, how do I do that?

Best Answer

sudo apt-get purge mysql-server apache2 php5

That will remove the "big-boy" packages, which should take care of most cases.

You can find this information in the documentation, specifically this section on how to start over:

To remove the LAMP stack remove the following packages:

Note: This assumes you have no other programs that require any of these packages. You might wish to simulate this removal first, and only remove the packages that don't cause removal of something desired.

sudo apt-get remove apache2 apache2-mpm-prefork apache2-utils apache2.2-common libapache2-mod-php5 libapr1 libaprutil1 libdbd-mysql-perl libdbi-perl libmysqlclient15off libnet-daemon-perl libplrpc-perl libpq5 mysql-client-5.0 mysql-common mysql-server mysql-server-5.0 php5-common php5-mysql

To also remove the debconf data, use the purge option when removing. To get rid of any configurations you may have made to apache, manually remove the /etc/apache2 directory once the packages have been removed.

Don't use tasksel to remove packages, bad things can happen, this is covered in this bug report.

The rest of the documentation covers how you would reinstall apache and all the stuff you'll need to get going again.

Ubuntu – How to move a LAMP setup to a new Ubuntu server

Your new server might not have the same hardware.
So install LAMPP server on the new system.
Shutdown the mysql service.

sudo /etc/init.d/mysql stop
Then copy /var/lib/mysql from the old system over to the new system.
Then copy /var/www from the old system to the new system.
Start up mysql again.

sudo /etc/init.d/mysql start

Note:

Most of the time copying /var/lib/mysql from one system to another system will work.
In anycase if that din work for you,then do mysqldump on the old server and run the resulting sql on the new server with mysqlimport.

mysqldump --all-databases > db_name.sql
mysqlimport db_name.sql
