- SCGI Interface
Module: mod_scgi
Description¶
Brief description of mod_scgi directives
| option | description | |
|---|---|---|
| scgi.debug | a value between 0 and 65535 to set the debug-level in the SCGI module | |
| scgi.server | tell the module where to send SCGI requests to | |
| scgi.protocol | protocol between lighttpd and backend server ("scgi" (default) or "uwsgi") | Added in 1.4.42 |
| scgi.server-option | description |
|---|---|
| host | is ip of the SCGI process |
| port | is tcp-port on the "host" used by the SCGI process |
| socket | path to the unix-domain socket |
| bin-path | path to the local SCGI binary which should be started if no local SCGI is running |
| bin-environment | set environment of SCGI binary |
| bin-copy-environment | copy environment from server for SCGI binary |
| listen-backlog | listen backlog queue size (for backend daemons started by mod_scgi) |
| docroot | docroot on the remote host |
| x-sendfile | controls if X-Sendfile header is allowed |
| x-sendfile-docroot | limits the directory trees permitted for use with X-Sendfile response header |
| broken-scriptfilename | breaks SCRIPT_FILENAME in a way that PHP can extract PATH_INFO from it |
| idle-timeout | number of seconds before a unused process gets terminated |
| max-procs | upper limit of processes to start |
| min-procs | sets the minium processes to start |
| min-procs-not-working | |
| max-load-per-proc | maximum number of waiting processes on average per process before a new process is spawned |
| check-local | enable/disable check for requested file in document root (default: enabled) |
| disable-time | time to wait before a disabled backend is checked again |
| strip-request-uri | strip part of request-uri |
Details for scgi.server parameters can be found in mod_fascgi documentation, since the SCGI module is heavily based on the FastCGI module, and fastcgi.server parameters are very similar.
Note "check-local" is enabled by default, due to historical reasons, but most users serving virtual paths will want to disable it. If enabled, lighttpd first checks for a file in the local 'server.document-root' tree and returns 404 (Not Found) if no such file exists. If disabled, lighttpd forwards the request to the backend without performing this check.
