how to check version openlitespeed on linux

On Linux, you can check the OpenLiteSpeed version with a few different methods depending on your access:


1. Using the OpenLiteSpeed binary

If OpenLiteSpeed is installed in its default location:

/usr/local/lsws/bin/lshttpd -v

or:

/usr/local/lsws/bin/openlitespeed -v

Example output:

LiteSpeed/1.8.4 Open (BUILD built: Thu Aug  7 20:42:39 UTC 2025) 
        module versions:
        lsquic 4.3.1
        modgzip 1.1
        cache 1.66
        mod_security 1.4 (with libmodsecurity v3.0.14)

2. Checking via systemctl status

If OpenLiteSpeed is running as a service:

systemctl status lsws

While this shows service status, it might also display the version in the description.


3. Using WebAdmin interface

If the WebAdmin console is enabled:

  1. Open your browser and go to:

    https://your-server-ip:7080
  2. Log in with your admin credentials.

  3. The version appears at the top of the dashboard.


4. Using package manager (if installed via repo)

  • On CentOS / AlmaLinux / RockyLinux:

rpm -qa | grep openlitespeed
  • On Ubuntu / Debian:

dpkg -l | grep openlitespeed

Output will include the installed version.
