Adding LUA module to nginx

I rpm installed nginx 1.12 on a redhat 7.5 server and It also has LUA 5.1.4 I downloaded lua-nginx-module-0.10.13 tar ball and put it under /etc/nginx/modules, but I am not able to run nginx with LUA auth file.

I also have openresty under /opt/openresty/ ..

http://openresty.org/en/installation.html I followed the "make" method here.

Unfortunately this server doesnt have access to the internet so I cant install stuff from git which slows this down considerably. I am not sure how to add the module here. Any comments would be helpful.

This is what my nginx config looks like ..

server
{
    listen 80;

    access_log  /opt/elk/logs/nginx/access.log  main;

    #auth_basic "admin";
    #auth_basic_user_file "/etc/nginx/passwd";

    client_max_body_size 100M;

    location /
    {
        proxy_pass http://127.0.0.1:9200;

        keepalive_timeout 300s;

        #auth_basic on;
        auth_basic "admin";
        auth_basic_user_file "/etc/nginx/passwd";

        access_by_lua_file '/etc/nginx/authorized.lua';
    }

    error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html
    {
        root   /usr/share/nginx/html;
    }
}

The lua_access_file is causing an error

nginx: [emerg] unknown directive "access_by_lua_file" Is there some "include" I need to define in the config to get rid of this ?

Thanks.

Now in most Operating Systems (e.g. Ubuntu, etc) Lua support for Nginx can be enabled by installing the libnginx-mod-http-lua package. e.g:

sudo apt install libnginx-mod-http-lua

This package includes the dynamic library and the corresponding load_module directive in /usr/share/nginx/modules-available/mod-http-lua.conf which is usually enabled when the package is installed (by softlinking it into the /etc/nginx/modules-enabled/ directory).

I am breaking down your problem into the small task, as per question and my understanding.

1) The error clearly says that you have not install Lua-nginx-module properly.

Lua-nginx-module documentation

2) The server does not have access to the internet so cannot download from git. *

  • Assuming you are doing ssh into your machine from windows. So, please check below link to copy the files from windows to Linux.

    Installing/Accessing via WinSCP

how-to-copy-files-from-one-machine-to-another-using-ssh

  • this step will get all the necessary files on your server.

3) Steps to install nginx with lua-nginx-module.

  • lua nginx module compatibility check.

     Nginx Compatibility
         The latest version of this module is compatible with the following versions of Nginx:
    
         1.13.x (last tested: 1.13.6)
         1.12.x
         1.11.x (last tested: 1.11.2)
         1.10.x
         1.9.x (last tested: 1.9.15)
         1.8.x
         1.7.x (last tested: 1.7.10)
         1.6.x
    
         Nginx cores older than 1.6.0 (exclusive) are not supported.
    

    referance document for nginx compatibility

  • Prerequisites

    **- Centos/RHEL**[**In case if internet is working in your server**].
    
     yum install -y wget unzip gcc make openssl-devel pcre-devel zlib-devel 
    

    - Downloading .rpm package manually and installing.

  1. Search the prerequisites from the RPM resource site

  2. Copy the file in your Linux box

    • Please refer above point (2)"The server does not have access to the internet so cannot download from git".
    1. Install with the following command.

        rpm -i rpm-package-name
      

    Install-rpm-file-on-linux

- Tarball installation for prerequisites.

 - [Installing gcc from source code ][6]         Similarly,you can look for
          other prerequistes.
  • Downloading the source

     $ rm -fr /tmp/nginx-build  
     $ mkdir /tmp/nginx-build
     $ cd /tmp/nginx-build
    
     $ wget http://nginx.org/download/nginx-1.13.0.tar.gz
    
     $ wget http://luajit.org/download/LuaJIT-2.0.4.tar.gz
    
     $ wget -O nginx_devel_kit.tar.gz https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz
    
     $ wget -O nginx_lua_module.tar.gz https://github.com/openresty/lua-nginx-module/archive/v0.10.8.tar.gz
    
  • Extracting

      $ tar xvf LuaJIT-2.0.4.tar.gz
    
      $ tar xvf nginx-1.11.10.tar.gz
    
      $ tar xvf nginx_devel_kit.tar.gz
    
      $ tar xvf nginx_lua_module.tar.gz
    
  • Building LuaJIT

    To build Nginx with LuaJIT, we need to build LuaJIT first. This is as simple as a make command

        $ cd /tmp/nginx-build/LuaJIT-2.0.4
        $ make install
         ==== Building LuaJIT 2.0.4 ====
         make -C src
         make[1]: Entering directory `/tmp/nginx/LuaJIT-2.0.4/src'
         ...
         ...
         ln -sf luajit-2.0.4 /usr/local/bin/luajit
         ==== Successfully installed LuaJIT 2.0.4 to /usr/local ====
    
  • Building Nginx

         $ cd /tmp/nginx-build/nginx-1.11.10

In case you are running nginx with docker you can just follow the instructions on the docker-nginx github repository.

In your nginx-conf make sure to also load the module by adding

load_module modules/ndk_http_module.so;
load_module modules/ngx_http_lua_module.so;
load_module modules/ngx_stream_lua_module.so;

Akshay barahate's answer is long and comprehensive. However to answer your question

Is there some "include" I need to define in the config to get rid of this ?

Try adding

load_module "ngx_http_lua_module.so"

The package name may vary, the above file name is derived from an ubuntu 18.04 installation from package. (Usually you find your modules in /usr/share/nginx/modules)

Note: If you compiled nginx from source (which seems to be the recommended way to get lua running), pathes and filenames can vary.

Happy codin'.
