OpenLiteSpeed for cPanel and WHM 0.7.0

olscp 0.7.0 runs OpenLiteSpeed as a drop-in replacement for Apache on cPanel and WHM servers.

What is new

• Safe switch: olscp enable checks every site over HTTP and HTTPS after the switch and restores Apache automatically if a site that worked on Apache fails on OpenLiteSpeed
• Dry run: olscp dry-run and the Dry run button start OpenLiteSpeed on the preview ports and check every site while Apache keeps serving, so you see which sites would break before switching
• The site checks connect only to the loopback address, send a HEAD request with the site as the Host header and read only the status line, with a per-site timeout and an overall time budget
• HTTP/3 (QUIC) can be turned off for named domains while it stays on for the rest
• Statistics show the cache hit ratio per server and per domain and the application pool use
• MultiPHP reports a PHP version that is set but not installed and falls back to the server default

See the changelog for the full list.

Install

git clone https://github.com/NeuralFoundry/openlitespeed-cpanel.git
cd openlitespeed-cpanel
bash install.sh

Apache keeps serving until you switch. Try olscp dry-run first, then switch from WHM > Plugins > OpenLiteSpeed or with olscp enable.

Prebuilt live .htaccess binary

The attached files are the patched OpenLiteSpeed 1.9.4 build for the optional live .htaccess reload, for EL8 and EL9 on x86_64. olscp downloads and verifies them against build/prebuilt.txt with olscp ols fetch --use. For AlmaLinux, Rocky Linux or CloudLinux 8 or 9.

OpenLiteSpeed for cPanel and WHM 0.5.0

Node.js and Python applications now run on OpenLiteSpeed.

New

• Applications from cPanel Application Manager and the CloudLinux Node.js and Python selectors start as the account user, with the same Passenger settings Apache uses
• Python applications run through a small WSGI server, libexec/lswsgi.py, with any Python 3.6 or newer interpreter or virtual environment
• WebSockets for Node.js applications
• WHM plugin: new Apps page with state and restart. Command line: olscp apps
• Applications restart when their settings change, and the LSCache storage of a site is purged when an application is added or removed
• /.well-known/ stays reachable for AutoSSL next to an application on the site root
• SSLRequireSSL in .htaccess is translated
• Unit tests in tests/

Ruby (Rack) applications are not supported yet.

Upgrade

cd openlitespeed-cpanel
git pull
bash install.sh

Existing sites keep the same configuration. Tested on cPanel & WHM 138 on AlmaLinux 9 with OpenLiteSpeed 1.9.4.
