Customer concern: sites with /home/<user>/public_html baked into config or the DB must keep working — a changed in-container docroot path would break WordPress ABSPATH, hardcoded includes, cached absolute paths, etc., making the upgrade a non-drop-in. Fix: the sidecar now mounts the docroot at /home/$user (IDENTICAL to cac-fpm/cac-litespeed) and the entrypoint symlinks /mnt/users/<user>/<domain> -> /home/$user. OLS still serves from its bulk /mnt/users mount and sends lsphp that path (no remap available), but the symlink resolves it to the real /home/$user files AND PHP canonicalises it — so __FILE__/__DIR__/realpath/ABSPATH all report /home/<user>/public_html. Verified end-to-end through the shared OLS: a request reports __FILE__=/home/homeuser/public_html/probe.php, ABSPATH=/home/homeuser/public_html/, and stored /home paths resolve. True 1:1 drop-in.

## entrypoint-lsphp.sh — PID 1 for cac-lsphp:phpNN.
|
|
##
|
|
## The per-site PHP backend for the SHARED OpenLiteSpeed tier. Runs lsphp in
|
|
## DETACHED LSAPI mode (`lsphp -b <addr:port>`) and nothing else — no
|
|
## webserver. The shared-ols container connects to this over the docker
|
|
## network (extProcessor type lsapi, address <this-container>:9000) exactly
|
|
## like the shared httpd connects to a cac-fpm container's php-fpm on :9000.
|
|
##
|
|
## Structurally identical to cac-fpm/cac-litespeed: same `uid`/`user` contract,
|
|
## the customer docroot mounted at /home/$user (so PHP sees /home/$user/public_html
|
|
## EXACTLY like the standalone tiers — true 1:1 drop-in for WordPress ABSPATH,
|
|
## config paths, and DB-stored absolute paths). The only difference is OLS lives
|
|
## in a separate container, so this PID 1 is lsphp itself.
|
|
##
|
|
## THE SYMLINK (see feedback_ols_lsapi_no_script_filename_remap): OLS has no
|
|
## ProxyFCGISetEnvIf-style remap — it hands lsphp exactly its vhost docRoot path.
|
|
## The shared-ols container serves from its bulk /docker/users->/mnt/users mount,
|
|
## so its docRoot (and the SCRIPT_FILENAME it sends us) is
|
|
## /mnt/users/<user>/<domain>/public_html. We create a symlink
|
|
## /mnt/users/<user>/<domain> -> /home/$user so that path resolves to the real
|
|
## /home/$user/public_html files. PHP canonicalises the symlink, so
|
|
## __FILE__/__DIR__/realpath all report /home/$user/public_html (verified
|
|
## 2026-06-10) — the customer never sees the /mnt/users path.
