The lsup Command

The lsup command is a simple way to update LiteSpeed Web Server from the command line, allowing the possibility of upgrading hordes of LSWS installations with a single command.

Location

The lsup command is located at $SERVER_ROOT/admin/misc/lsup.sh. In most CentOS installations, the command is thus:

/usr/local/lsws/admin/misc/lsup.sh

Function

Running the basic lsup command will automatically upgrade your installation of LiteSpeed Web Server to the latest release. There are also options for customizing the command listed below.

Options

  • -f: If you already have the version to be installed, the basic lsup command will abort. The -f option forces lsup to install even if the version you have is the same version as the LSWS to be installed. This can be useful if there has been a change in the build since you upgraded, but a new build has not yet been released.
  • -v: You can control what version you install with the -v option followed by a version number. (For example: ./lsup.sh -v 4.2.2) This will allow you to downgrade to older versions if you run into a bug. Keep in mind, LiteSpeed only keeps the most recent few versions available. Much older versions are not available.
  • -b: Designates a build number. All versions start from build 0. To view what build you are currently using, view /usr/local/lsws/autoupdate/build. Will automatically upgrade to the latest build of the designated version if -b is not set. (Only available for versions 5.0 and higher.)
