   note

   The installer will use the Windows Installer Interface if the process mode (/quiet or /passive) is unspecified.

   Example

   To uninstall openit_10_2_500_server_windows_x64.msi, located at C:\Installers, in unattended mode with all logging information stored in an output log file at C:\uninstall.log:

   Example

   msiexec /x C:\Installers\openit_10_2_500_server_windows_x64 /l*v "C:\uninstall.log" /passive
   note

   When using the passive mode, wait until the process bar dialog disappears.

   When using the quiet mode, verify that the uninstallation is complete by opening the Task Manager and checking in the Details tab if the msiexec process is still running.

Uninstalling through the Control Panel

Uninstalling through the Terminal

1. Go to the dist folder or to /opt/openit/bin.

2. Run the uninstall script using one of the following options:

   Run from the current directory:

   Command Syntax (Option 1)

   ./uninstall

   or run the uninstall script directly from the directory:

   Command Syntax (Option 2)

   /opt/openit/bin/uninstall

   or run the script from the dist directory:

   Command Syntax (Option 3)

   dist/uninstall

3. Type y and press Enter for each prompt until the uninstallation process is finished.

   Example Output

   [list of scripts]
   Proceed? [n] : y
   
   The following directories contain data that must be saved when
   uninstalling and doing an upgrade of the current version:
   
    DATA_DIR/database
    DATA_DIR/incoming
    DATA_DIR/archives
    ROOT_HTML_DIR/periodic_reports
    ROOT_HTML_DIR/results
   
   (These directories will only be removed by uninstall script if
   installed under /opt/openit or /var/opt/openit)
   
   Open iT configuration files and directories that should be saved
   are:
   
    /etc/opt/openit/openit.cfg
    /var/opt/openit/etc
   
   These files/directories are now going to be REMOVED!
   
   Continue removing Open iT software and configuration? [n] : y
   
   * Removing installed files. . . . . . . . . .done
   
   Uninstall done. There seems to be some Open iT processes still
   running. Please kill them exclusively and verify that there are no 
   more Open iT processes running on your system, before you proceed 
   with further operations

   For an uninterrupted uninstallation, run:

   Command Syntax

   ./uninstall -b -n

   For more information regarding the arguments, type in:

   Command Syntax

   ./uninstall --help

   This shows the manual page for the uninstall script:

   Command Output

   Usage: uninstall [ -b ] [ -n ]
       -b batch uninstall (without user input)
       -n don't transfer client data to server before uninstall

Removing the Software Manually

1. Disable automatic (re)starting of Open iT. Remove the startup script in the system(s) (/etc/rc../) directory (or equivalent) during installation. It can be done the same way other files are removed from the system.

   If crontab entries have been installed to check that Open iT daemons are running, they should also be removed. Make sure that the server entry that checks for the Open iT httpd daemon is also removed.

   Examples of crontab entries that must be searched for are:

   Examples

   32 * * * * su - openit -c "/opt/openit/bin/check_daemon server"  # Open iT
   31 * * * * /opt/openit/bin/check_daemon httpd  # Open iT
   34 * * * * su - openit -c "/opt/openit/bin/check_daemon logger"  # Open iT
   33 * * * * /opt/openit/bin/check_daemon client  # Open iT

2. Stop all Open iT processes. Make sure that any valuable data has been backed up before proceeding. Run the command:

   Command Syntax

   /opt/openit/bin/openit-all stop

   If each process must be stopped individually, appropriate script must be used along with the argument stop.

   To stop the Open iT server:

   Command Syntax

   /opt/openit/bin/openit-server stop

   To stop the Open iT logger (if configured to run with the server):

   Command Syntax

   /opt/openit/bin/openit-logger stop

   To stop the process scheduler:

   Command Syntax

   /opt/openit/bin/openit-scheduler stop

   To stop the HTTP:

   Command Syntax

   /opt/openit/bin/openit-httpd stop

3. Forcefully remove any Open iT files and directories related to the installation.

   Command Syntax

   rm -rf /opt/openit
   rm -rf /var/opt/openit
   rm -rf /etc/opt/openit
   note

   If the installation was not created in the default destination (/opt/openit), the link from /opt/openit in the installation directory must also be removed.
