How to remove Customer and Business Manager in Plesk

One of the questions that came up at Parallels Summit recently was how to uninstall Customer and Business manager. Plesk doesn’t offer a solution to uninstall things – even though you can add modules, once they’re installed they’re installed.

Luckily I remember a good forum thread that’s a bit long so I’ll give you a concise version here.

Note: this works in Plesk 10.4.4 and 11.0.9 for Linux (CentOS) – I haven’t tried earlier or later versions or other distributions at the time of writing. If you have any feedback, please leave a comment.

Part 1: Remove Single-Sign-On

Log in with your favourite SSH tool and issue the following command as root:

/usr/local/psa/bin/sso --disable

Part 2: Removing the RPM packages

Log in with your favourite SSH tool and issue the following command as root:

rpm -e plesk-billing plesk-billing-plugins sw-sso

Now the files are removed, however the Plesk GUI will still tell you that “the installation was successful” and if you click the link provided it’ll be re-installed. So ignore that link and move on to

Part 3: Database Cleanup

Head over to the phpMyAdmin tool (under Tools and Settings – Database Servers) and open the psa database. In it you’ll find two values which we need to clear out.

Find a table called ‘cl_param’, then delete the value ‘ppb-url’. Restart plesk from the command line via

service psa restart

When you log back in, Customer and Business Manager should be history – including all those extra links on the left hand side.

Alternatively, if you want to stay on the command line, login to MySQL with

mysql -uadmin -p`cat /etc/psa/.psa.shadow` psa


and then issue the following command to get the same result:

delete from cl_param where param='ppb-url';

You should get a message like “Ok, 1 row affected”. Quit the MySQL prompt.
