The official binary Win32 and Win64 distributions of OpenResty can be downloaded from the following web page:

https://openresty.org/en/download.html

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

```bash

start nginx

```

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

```bash

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:

```console

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 MSYS2 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:

```bash

nginx -s stop

```

or gracefully shut it down like this:

```bash

nginx -s quit

```

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

```console

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 MSYS2 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:

```console

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 MSYS2 perl.

recommended though).

Debug symbols are enabled even in release builds. So that when things go very wrong,

one can still debug things with tools like MSYS2 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.

The Win32/Win64 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/Win64 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).

[Back to TOC](#table-of-contents)

* 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/Win64 binary package built with best debugging capabilities (like enabling

NGINX debugging logs, disabling C compiler optimizations, and enabling all the assertions and checks).

Details About The Building Process

Usually you do not need to worry about how the Win32/Win64 binaries were built on the maintainers''

side. But if you do, please read on.

The Win32/Win64 build of OpenResty is currently built via the MSYS2/MinGW toolchain, including

MinGW gcc 7.2.3, MSYS2 perl 5.24.4, MSYS2 bash, MSYS2 make, and etc. Basically, it is currently built via

the following commands:

```bash

mkdir -p objs/lib || exit 1

cd objs/lib || exit 1

ls ../../..

tar -xf ../../../$OPENSSL.tar.gz || exit 1

tar -xf ../../../$ZLIB.tar.gz || exit 1

tar -xf ../../../$PCRE.tar.gz || exit 1

cd ../..

cd objs/lib/$OPENSSL || exit 1

patch -p1 < ../../../patches/openssl-1.1.0d-sess_set_get_cb_yield.patch || exit 1

cd ../../..

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](https://github.com/openresty/openresty/blob/master/util/build-win32.sh).

Furthermore, we automate the packaging process of the resulting binaries and supporting files

with this [package-win32.sh](https://github.com/openresty/openresty/blob/master/util/package-win32.sh)

script.

Usually you can just download and use the binary distribution of OpenResty without

installing the build toolchain.
