nginx for Windows
Known issues Possible future enhancements |
Version of nginx for Windows uses the native Win32 API (not the Cygwin emulation
layer).
Only the select()
and poll()
(1.15.9)
connection processing methods are 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 mainline version distribution (1.27.3),
since the mainline branch of nginx contains all known fixes.
Then unpack the distribution, go to the
nginx-1.27.3
directory, and run nginx
.
Here is an example for the drive C: root directory:
cd c:\ unzip nginx-1.27.3.zip cd nginx-1.27.3 start nginx
Run the tasklist
command-line utility
to see nginx processes:
C:\nginx-1.27.3>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 logs\error.log
.
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 logs\error.log
file.
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
C:\nginx-1.27.3\
.
Paths in a configuration file must be specified in UNIX-style using
forward slashes:
access_log logs/site.log; root C:/web/html;
nginx/Windows runs as a standard console application (not a service), and it can be managed using the following commands:
nginx -s stop fast shutdown nginx -s quit graceful shutdown nginx -s reload changing configuration, starting new worker processes with a new configuration, graceful shutdown of old worker processes nginx -s reopen re-opening log files
Known issues
- Although several workers can be started, only one of them actually does any work.
- The UDP (and, inherently, QUIC) functionality is not supported.
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.
