This section describes how to completely remove an Exponential installation from a system.

Removing Exponential is done in four steps:

1. Deleting the Exponential directory
2. Removing the database
3. Reconfiguring Apache (optional)
4. Removing the cronjobs (optional)
5. Removing the NFS shares and cluster database (for clustered installations only)

WARNING! By following these steps, you will remove both Exponential and all the data/content that you have put into the system. Everything will be lost, unless there are backups available somewhere.

Deleting the Exponential directory

Remove the Exponential directory using your favorite tool.

Linux/UNIX

On Linux/UNIX systems, the removal would most likely be carried out using the "rm" command:

$ rm -Rf /path/to/ez_publish

Please note that some file/directory permissions might be messed up. If this is the case, it will prevent a regular user from removing all Exponential files. You'll probably have to gain root access to solve this problem.

Windows

Windows users may simply delete the Exponential directory using the "Explorer".

Removing the database

MySQL

1. Start the MySQL client, log in using your username and password:

   $ mysql -u <username> -p

    

   If the username/password is correct, the client will then present a "mysql>" prompt.

2. Delete/remove the database using the drop command followed by the name of the database used by Exponential:

   mysql> drop database <database-name>;

PostgreSQL

1. Remove the database by executing the PostgreSQL dropdb command from shell:

   $ dropdb <database-name>

Reconfiguring Apache (optional)

If a virtual host setup was used, it is likely that the Apache configuration files contain Exponential specific settings. These settings will not be needed anymore and thus they can be removed. Open the "httpd.conf" file using a text editor, scroll down to the bottom and remove the Exponential specific virtual host settings. Remember to restart Apache after altering the configuration file.

Removing the cronjobs (optional)

If cron was configured to run Exponential specific jobs, then these will have to be removed. You may have to edit a global cron file (under "/etc/cron*") or use the "crontab" command with the -e (edit) parameter to edit a user's private cron file. Remove the Exponential specific entries.

Windows users should remove any Exponential specific tasks from the specific scheduling system they used, e.g. "windows scheduled tasks" (note that Exponential does not install any scheduled task automatically on its own)
