Uninstallation

Ignition installations contain an uninstaller executable that is created during a new installation. When Ignition is uninstalled, the settings database and folder (contained in the /data) folder is backed up to /data_<current date>. Similarly, modules and user-supplied JDBC jars (contained in the /user-lib folder), are backed up to /user-lib_<current date>. The Ignition service is also removed from Windows and Ubuntu Linux installations automatically. Be sure to back up your gateway and unactivate your gateway license before uninstalling!

Windows:

To run the uninstaller, open the start menu and navigate to Programs > Inductive Automation > Ignition and select Uninstall Ignition. The uninstaller wizard will guide you through the uninstallation process. You can also uninstall Ignition from the Add/Remove Programs section of the Windows Control Panel.

Linux (using downloaded installer):

Linux installations contain an uninstaller executable as long as the original installation was Ignition 7.3 or later. To run the uninstaller, open a command shell and navigate to /user/local/bin/ignition (or your installation folder) and run ./uninstall as root or sudo.

Linux Ignition installations before 7.3 utilized a zip file that was exploded in place to form an installation. Since these installations were never created with an installer executable, no uninstaller executable was ever generated. This is true even if using a 7.3 or later installer executable to upgrade an installation from before 7.3. For these installations, you must manually remove the Ignition folders using the commands below.

/etc/init.d/ignition stop

*Ubuntu only* update-rc.d -f ignition remove

rm /etc/init.d/ignition

rm -rf /usr/local/bin/ignition

*Recommended* mv /var/lib/ignition/data /var/lib/ignition/data_<current date>

*Recommended* mv /var/lib/ignition/user-lib /var/lib/ignition/user_lib_<current date>

*Recommended* mv /etc/ignition /etc/ignition_<current date>

rm -rf /var/log/ignition

Ubuntu Package Management Uninstallation:

Installations using the Ubuntu Package Manager offer the choice to remove the installation while retaining the configuration files in /etc, or to completely purge the installation from the system. If you choose to purge the installation, Ubuntu will need to download Ignition again if you would like to reinstall Ignition.

Simple removal: open a command shell and run sudo apt-get remove ignition (for stable installations) or sudo apt-get remove ignition-beta (for beta installations).

Full removal and purge: open a command shell and run sudo apt-get purge ignition (for stable installations) or sudo apt-get purge ignition-beta (for beta installations).
