® is a full-fledged web platform that integrates the standard Nginx core, LuaJIT, many carefully written Lua libraries, lots of high quality 3rd-party Nginx modules, and most of their external dependencies. It is designed to help developers easily build scalable web applications, web services, and dynamic web gateways.

Binary Packages

OpenResty® provides official pre-built packages for some of the common distributions (, , CentOS, RHEL, Fedora, and Amazon ). Make sure you have checked out these binary packages first if you are on .

We also provide pre-built Win32 packages for OpenResty® on the Download page. And you should also check out this documentation instead.

It is highly recommended to install OpenResty on our Mac OS X or macOS systems via homebrewpackage manager, like this:

brew install homebrew//openresty

Building from Source

If you haven’t downloaded the OpenResty source code tarball, please go to the Download page first.

Basically, building and installing OpenResty is as simple as

tar -xvf openresty-VERSION.tar.gz
cd openresty-VERSION/
./configure -j2
make -j2
sudo make install

# better also add the following line to your ~/.bashrc or ~/.bash_profile file.
export PATH=/usr/local/openresty/bin:$PATH

where VERSION should be replaced by a concrete version number of OpenResty, like 1.11.2.5.

You can add 3rd-party NGINX modules or enable other NGINX core features just like with the standard NGINX distribution. For example, you can use the --add-module=PATH or --add-dynamic-module=PATH options of OpenResty’s ./configure tool to insert 3rd-party NGINX C modules. But please note that 3rd-party NGINX C modules not maintained by OpenResty are not supported by OpenResty and they may compromise OpenResty’s stability.

You can use the  ./configure --help to see all the available options that you can use to enable and/or disable certain components or features of OpenResty during build time.

To start your OpenResty®, you can just use the openresty command in place of your original nginx command as long as you have correctly added the <openresty-prefix>/bin/ directory to your system environment PATH (<openresty-prefix> is default to /usr/local/openresty/ unless being overridden by ./configure‘s --prefix=PATH option).

You can also invoke the resty command-line utility to run a head-less OpenResty program or the restydoc tool to browse OpenResty documentation on the terminal.

If your system environment is modern enough, then you almost always want to enable the PCRE JIT support and IPv6 support in your NGINX by passing the --with-pcre-jit and --with-ipv6options to the ./configure script.

./configure --with-pcre-jit --with-ipv6

By default, OpenResty is installed into the prefix /usr/local/openresty/.

Finally, you need to add the command-line utilities provided by OpenResty to your PATHenvironment, as in

export PATH=/usr/local/openresty/bin:/usr/local/openresty/nginx/sbin:$PATH

if you are using bash. Better add this line to your shell’s startup script, like ~/.bashrc or ~/.bash_profile.

If you have problems while building or want finer control over the building process, please read on.

Prerequisites

You should have perl 5.6.1+libpcrelibssl installed into your system. For Linux, you should also ensure that ldconfig is in your PATH environment.

Debian and Ubuntu users

You’re recommended to install the following packages using apt-get:

apt-get install libpcre3-dev \
    libssl-dev perl make build-essential curl

Fedora and RedHat users

You’re recommended to install the following packages using :

yum install pcre-devel openssl-devel gcc curl

Mac OS X (macOS) users

It is highly recommended to install OpenResty on our Mac OS X or macOS systems via homebrewpackage manager, like this:

brew install homebrew/nginx/openresty

You’re recommended to install prerequisites PCRE and OpenSSL using some package management tool, like Homebrew:

brew update
brew install pcre openssl curl

Alternatively you can install PCRE and/or OpenSSL from source all by yourself 🙂

After installing PCRE and OpenSSL, you may need to specify the paths for their headers and libraries to your C compiler and linker, for example,

$ ./configure \
   --with-cc-opt="-I/usr/local/opt/openssl/include/ -I/usr/local/opt/pcre/include/" \
   --with-ld-opt="-L/usr/local/opt/openssl/lib/ -L/usr/local/opt/pcre/lib/" \
   -j8

assuming that your PCRE and OpenSSL are installed under the prefix /usr/local/opt/ which is the default for homebrew.

See also Issue #3.

FreeBSD users

You need to install the following ports:

  • devel/gmake
  • security/openssl
  • devel/pcre

Building OpenResty

download the latest openresty tarball can be fetched from the Download page and unpack it like this:

tar -xzvf openresty-VERSION.tar.gz

where VERSION should be replaced by real version numbers like 1.11.2.5.

./configure

Then enter the openresty-VERSION/ directory, and type the following command to configure:

./configure

By default, --prefix=/usr/local/openresty is assumed. You should only disable LuaJIT 2 when your platform does not support LuaJIT.

You can specify various options, as in

./configure --prefix=/opt/openresty \
            --with-pcre-jit \
            --with-ipv6 \
            --without-http_redis2_module \
            --with-http_iconv_module \
            --with-http_postgres_module \
            -j2

All of the standard Nginx configure file options can be used here, including --add-module=PATH for adding your own 3rd-party Nginx C modules. Try ./configure --help to see more options available.

Errors in running the ./configure script can be found in the file build/nginx-VERSION/objs/autoconf.err where VERSION should be replaced by a concrete version number of OpenResty, like 1.11.2.5.

Notes for Solaris users

For Solaris, it’s common to install libraries like OpenSSL to /lib, so when it complaints about missing OpenSSL and you have indeed already installed it, specify the --with-ld-opt='-L/lib'option.

make

Now you can compile everything up using the command

make

If your machine has multiple cores and your make supports the jobserver feature, you can compile things in parallel like this:

make -j2

assuming you have 2 cores.

make install

If all the previous steps go without problems, you can install OpenResty into your system by typing the command

make install

On Linux, it often requires sudo to gain access.

If you prefer building the OpenSSL and PCRE dependencies from their source tarballs, then you could follow the commands below (you may want to change the version number accordingly):

wget https://www.openssl.org/source/openssl-1.0.2k.tar.gz
tar -zvxf openssl-1.0.2k.tar.gz
cd openssl-1.0.2k/
patch -p1 < /path/to/openresty/patches/openssl-1.0.2h-sess_set_get_cb_yield.patch
cd ..

wget ://.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.40.tar.gz
tar -xvf pcre-8.40.tar.gz

wget https://openresty.org/download/openresty-1.11.2.5.tar.gz
tar -zxvf openresty-1.11.2.5.tar.gz
cd openresty-1.11.2.5/

## assuming your have 4 spare logical CPU cores

./configure --with-openssl=../openssl-1.0.2k \
                 --with-pcre=../pcre-8.40 -j4
make -j4
sudo make install
