Version of nginx for Windows uses the native Win32 API (not the Cygwin emulation
select() connection processing method is currently used,
so high performance and scalability should not be expected.
Due to this and some other known issues version of nginx for Windows
is considered to be a beta version.
At this time, it provides almost the same functionality as a UNIX version
of nginx except for
XSLT filter, image filter, GeoIP module, and embedded Perl language.
To install nginx/Windows, download
the latest development version distribution (1.5.0),
since the development branch of nginx contains all known fixes.
Then unpack the distribution, go to the
directory, and run
Here is an example for the drive C: root directory:
tasklist command-line utility
to see nginx processes:
C:\nginx-1.5.0>tasklist /fi "imagename eq nginx.exe"
Image Name PID Session Name Session# Mem Usage
=============== ======== ============== ========== ============
nginx.exe 652 Console 0 2 780 K
nginx.exe 1332 Console 0 3 112 K
One of the processes is the master process and another is the worker process.
If nginx does not start, look for the reason in
the error log file
If the log file has not been created, the reason for this should be reported
in the Windows Event Log.
If an error page is displayed instead of the expected page, also look
for the reason in the
nginx/Windows uses the directory where it has been run as the prefix
for relative paths in the configuration.
In the example above, the prefix is
Paths in a configuration file must be specified in UNIX-style using
nginx/Windows runs as a standard console application (not a service),
and it can be managed using the following commands:
|nginx -s stop
|nginx -s quit
|nginx -s reload
starting new worker processes with a new configuration,
graceful shutdown of old worker processes
|nginx -s reopen
||re-opening log files
Although several workers can be started, only one of them
actually does any work.
A worker can handle no more than 1024 simultaneous connections.
The cache and other modules which require shared memory support do not work
on Windows Vista and later versions due to
address space layout randomization being enabled in these Windows versions.
Possible future enhancements
Running as a service.
Using the I/O completion ports as a connection processing method.
Using multiple worker threads inside a single worker process.
