Debugging nginx with DTrace pid provider This article assumes the reader has a general knowledge of nginx internals and DTrace. Although nginx built with the --with-debug option already provides a lot of information about request processing, it is sometimes desirable to trace particular parts of code path more thoroughly and at the same time omit the rest of debugging output. DTrace pid provider (available on Solaris, Mac OS X) is a useful tool to explore userland program’s internals, since

Syntax: dav_methods off | method ...; Default: dav_methods off; Context: http, server, location Allows the specified HTTP and WebDAV methods.

Controlling nginx Changing Configuration Rotating Log-files Upgrading Executable on the Fly nginx can be controlled with signals. The process ID of the master process is written to the file /usr/local/nginx/logs/nginx.pid by default. This name may be changed at configuration time, or in nginx.conf using the pid directive. The master process supports the following signals: TERM, INT fast shutdown QUIT graceful shutdown HUP changing configuration, keeping up with a changed time zone (only for
