1. Install the dependencies

    OpenResty 1.13.6.2. Kong being an OpenResty application, you must follow the OpenResty installation instructions. You will need OpenSSL and PCRE to compile OpenResty, and to at least use the following compilation options:

     $ ./configure \
       --with-pcre-jit \
       --with-http_ssl_module \
       --with-http_realip_module \
       --with-http_stub_status_module \
       --with-http_v2_module
    

    You might have to specify --with-openssl and you can add any other option you’d like, such as additional Nginx modules or a custom --prefix directory.

    OpenResty conveniently bundles LuaJIT and resty-cli which are essential to Kong. Add the nginx and resty executables to your $PATH:

     $ export PATH="$PATH:/usr/local/openresty/bin"
    

    Luarocks 2.4.3, compiled with the LuaJIT version bundled with OpenResty (See the --with-lua and --with-lua-include configure options). Example:

     ./configure \
       --lua-suffix=jit \
       --with-lua=/usr/local/openresty/luajit \
       --with-lua-include=/usr/local/openresty/luajit/include/luajit-2.1
    
  2. Install Kong

    Now that OpenResty is installed, we can use Luarocks to install Kong’s Lua sources:

     $ luarocks install kong 0.14.1-0
    

    Or:

     $ git clone git@github.com:Kong/kong.git
     $ cd kong
     $ [sudo] make install # this simply runs the `luarocks make kong-*.rockspec` command
    

    Finally, place the bin/kong script in your $PATH.

  3. Add kong.conf

    Note: This step is required if you are using Cassandra; it is optional for Postgres users.

    By default, Kong is configured to communicate with a local Postgres instance. If you are using Cassandra, or need to modify any settings, download the kong.conf.default file and adjust it as necessary. Then, as root, add it to /etc:

     $ sudo mkdir -p /etc/kong
     $ sudo cp kong.conf.default /etc/kong/kong.conf
    
  4. Prepare your database

    Configure Kong so it can connect to your database. Kong supports both PostgreSQL 9.5+ and Cassandra 3.x.x as its datastore.

    If you are using Postgres, provision a database and a user before starting Kong:

     CREATE USER kong; CREATE DATABASE kong OWNER kong;
    

    Next, run the Kong migrations:

     $ kong migrations up [-c /path/to/kong.conf]
    

    Note: Migrations should never be run concurrently; only one Kong node should be performing migrations at a time.

  5. Start Kong

     $ kong start [-c /path/to/kong.conf]
    
  6. Use Kong

    Verify that Kong is running:

     $ curl -i http://localhost:8001/
