Running a renderserver¶
Running a renderserver consists in running multiple programs . Unless you have some special requirements, you should be able to start a working renderserver by running the following commands:
$ nserve $ mw-qserve $ nslave --cachedir ~/cache/ $ postman
These programs have the following purposes:
- nserve is a HTTP server. The Collection extension is talking to that program directly. nserve uses at least one mw-qserve instance in order to distribute and manage jobs.
- mw-qserve is a job queue server used to distribute and manage jobs. You should start one mw-qserve instance for each machine that is supposed to render pdf files. Unless you’re operating the Wikipedia installation, one machine should suffice.
- nslave pulls new jobs from exactly one mw-qserve instance and calls the mw-zip and mw-render programs in order to download article collections and convert them to different output formats. nslave uses a cache directory to store the generated documents. nslave also starts an internal http server serving the content of the cache directory.
- postman uploads zip collections to pediapress in case someone likes to order printed books. You should start one instance for each mw-qserve instance.

nserve understands the following options:
specify port to listen on. Default is to listen on port 8899 on any interface.
- register qserve instance running on host HOST listening on port PORT
Any additional arguments are interpreted as additional qserve instances to register.
The following command starts nserve listening on port 8000 using two qserve instances:
nserve --port 8000 example1:14311 example2
mw-qserve understands the following options:
- specify port to listen on. Default is to listen on port 14311
- specify interface to listen on. Default is to listen on any interface.
nslave understands the following options:
specify cachedir to use. this is where nslave will store generated documents.
- port on which to start the http server (default is 8898)
- specify url under which the cache directory is being served. The default is to compute this value dynamically.
- allow up to NUMPROCS parallel jobs to be executed
postman understands the following options:
- specify cachedir to use. use the same value as specified when calling nslave
