Name

README-win32 - README for the Windows 32-bit build of OpenResty

Description

The binary distributions of OpenResty can be downloaded from the following web page:

https://openresty.org/#Download

To start the NGINX server of the nginx server of the Win32 binary distribution of OpenResty:

start nginx

You can also specify the -p PATH/ option to override the default server prefix, as in

cd /path/to/my/openresty/app/
start nginx -p $PWD

Then you can use the tasklist command to check the nginx processes running in the background:

C:\> tasklist /fi "imagename eq nginx.exe"

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
nginx.exe                     4616 Console                    1      7,412 K
nginx.exe                     5836 Console                    1      7,800 K

One of the two processes is the master process while the other is the worker.

If you are using the MSYS bash instead of the cmd.exe console, then you should replace the /fi option with -fi in the command above instead.

You can quickly shut down the server like this:

nginx -s stop

or gracefully shut it down like this:

nginx -s quit

You can also forcibly kill the nginx processes via their PIDs with taskkill, as in

C:\> taskkill /pid 5488 /F

where the PID (5488 in this example) can be found via the aforementioned tasklist command.

Again, you should use the form -pid and -F for the options if you are in an MSYS bash session.

Similarly, you can use the nginx -s reload command to reload nginx configurations without stopping the server. And you can use nginx -s reopen to instruct nginx to re-open all the log files.

You can run the resty script like this:

C:\> resty -e "ngx.say('Hello, OpenResty!')"
Hello, OpenResty!

The resty command-line utility requires a Perl interpreter installed in your system and visible to your PATH environment. Any perl distributions should work, including StrawberryPerl, ActivePerl, and MSYS perl (the former two are recommended though).

Debugging

Debug symbosl are enabled even in release builds. So that when things go very wrong, one can still debug things with tools like MSYS GDB.

Inclusion of debug symbols make the binary files (.exe and .dll files) much larger, but it generally will not load into memory during normal execution on a modern operating system.

Caveats

The Win32 port of the NGINX core supports the good old select IO multiplexing mechanism only. The I/O Completion Ports (IOCP) feature is not supported (yet). So do not use this build for production environments with very high concurrency levels.

This Win32 build of OpenResty is mainly for developers who want to develop their applications in native Windows environment (though they eventually push the finished work onto a Linux or *BSD box, most of the time).

TODO

  • Add support for more than one NGINX worker processes.
  • Add support for concurrent connections more than 1024.
  • Switch to the Microsoft Visual Studio compiler toolchain for better performance and easier binary package redistribution.
  • Bundle StrawberryPerl to make command-line utilities like resty work out of the box (without manually installing a Perl).
  • Deliver an alternative Win32 binary package built with best debuggin capabilities (like enabling NGINX debugging logs, disabling C compiler optimizations, and enabling all the assertions and checks).
  • Deliver binary packages for 64-bit Windows (Win64).

Details About The Building Process

Usually you do not need to worry about how the Win32 binaries were built on the maintainers'' side. But if you do, please read on.

The Win32 build of OpenResty is currently built via the MinGW/MSYS toolchain, including MinGW gcc 4.8.1, MSYS perl, MSYS bash, MSYS make, and etc. Basically, it is currently built via the following cmmands:

mkdir -p objs/lib || exit 1
cd objs/lib || exit 1
ls ../../..
tar -xf ../../../openssl-1.0.2d.tar.gz
tar -xf ../../../zlib-1.2.8.tar.gz
tar -xf ../../../pcre-8.37.tar.gz
cd ../..
./configure --with-cc=gcc \
    --prefix= \
    --with-cc-opt='-DFD_SETSIZE=1024' \
    --with-select_module \
    --with-ipv6 \
    --sbin-path=nginx.exe \
    --with-pcre-jit \
    --with-luajit-xcflags="-DLUAJIT_NUMMODE=2 -DLUAJIT_ENABLE_LUA52COMPAT" \
    --with-pcre=objs/lib/pcre-8.37 \
    --with-zlib=objs/lib/zlib-1.2.8 \
    --with-openssl=objs/lib/openssl-1.0.2d \
    -j5
make
make install

where the dependency library source tarballs for OpenSSL, Zlib, and PCRE are downloaded from their official sites, respectively.

We automate these commands in a dedicated shell script named build-win32.sh.

Furthermore, we automate the packaging process of the resulting binaries and supporting files with this package-win32.sh script.

Usually you can just download and use the binary distribution of OpenResty without installing the build toolchain.
