nginx supports the following command-line parameters: * -? | -h — print help for command-line parameters. * -c file — use an alternative configuration file instead of a default file. * -g directives — set global configuration directives, for example, ~~~ nginx -g "pid /var/run/nginx.pid; worker_processes `sysctl -n hw.ncpu`;" ~~~ * -p prefix — set nginx path prefix, i.e. a directory that will keep server files (default value is /usr/local/nginx). * -q — suppress non-error messages during configuration testing. * -s signal — send a signal to the master process. The argument signal can be one of: * stop — shut down quickly * quit — shut down gracefully * reload — reload configuration, start the new worker process with a new configuration, gracefully shut down old worker processes. * reopen — reopen log files * -t — test the configuration file: nginx checks the configuration for correct syntax, and then tries to open files referred in the configuration. * -T — same as -t, but additionally dump configuration files to standard output (1.9.2). * -v — print nginx version. * -V — print nginx version, compiler version, and configure parameters.
