    Nginx 1.13.x
    MariaDB 5.5
    Thinking of adding optional support for Openresty's Nginx Lua and LuaJIT modules - HttpLuaModule - Nginx Community

    See example at Pushing Nginx to its limit with Lua

    However, I am not familiar with Lua and usage cases aren't as detailed online. So any user here actually uses Lua/LuaJIT with Nginx on other platforms ? If so any simple usage example cases I can look at that you use as well so I can confirm what I install for Centmin Mod Nginx works as intended ?

    It's optional so you can disable it via ORESTY_LUANGINX='n' in centmin.sh if you have no use for it

    Code:
    ORESTY_LUANGINX='y'          # enable or disable or ORESTY_LUA* nginx modules below
    ORESTY_LUANGINXVER='0.9.16rc1'  # openresty lua-nginx-module https://github.com/openresty/lua-nginx-module

    checking if luaJIT installed in vhost.conf add to server{} context
    Code:
    location = /lua {
        default_type text/plain;
        content_by_lua '
            if jit then
                ngx.say(jit.version)
            else
                ngx.say("Not LuaJIT!")
            end
        ';
    }
    save vhost.conf and restart nginx server and access hostname/lua will give
    Code:
    LuaJIT 2.0.4
    and the lua external libs

    Nginx Lua Youtube video by Yichun Zhang at Nginx.conf 2014

    Introduction · openresty/lua-nginx-module Wiki · GitHub
    Also posted standalone Centmin Mod .08 beta 02 + lua support branch at centminmod/centminmod at 123.08lua · GitHub if anyone wants to try it out. Commit history for 123.08lua branch Commits · centminmod/centminmod · GitHub (basically all of May 25th commits)

    Centmin Mod installed for 123.08beta03 branch via Github

    Step 1.

    Select the branch you want to install from list at Branches · centminmod/centminmod · GitHub and define it in the variable named branchname typed on SSH command line as follows.
    Code:
    branchname=123.08beta03
    
    Step 2.

    Actual install
    Code:
    yum -y install wget nano bc unzip
    branchname=123.08beta03
    wget -O /usr/local/src/${branchname}.zip https://github.com/centminmod/centminmod/archive/${branchname}.zip
    cd /usr/local/src
    unzip ${branchname}.zip
    cd centminmod-${branchname}
    chmod +x centmin.sh
    
    Then to install either type

    for menu mode
    Code:
    ./centmin.sh
    
    or for CLI install mode
    Code:
    ./centmin.sh install

    Hi,

    Lua is really light weight and can be used for many purposes where nginx rules would normally fail. You can use it for WAF (web application firewall) and even speed up your site if you use CloudFlare with it.

    This module is useless for us unless we do LUA config right?
    And to disable this, just modify ORESTY_LUANGINX='n' ?
    No need for LUAJIT_GITINSTALL='n'?

    yeah if you have no need or use for nginx lua, then in centmin.sh set

    Code:
    LUAJIT_GITINSTALL='n'
    ORESTY_LUANGINX='n' 
    then run centmin.sh option 4 to recompile Nginx server :)

    LuaJIT is only needed if Nginx LUA is enabled.. so if you have ORESTY_LUANGINX='n', you have no use for LuaJIT

    Updated Centmin Mod 123.09beta01 to Nginx Lua 0.9.19 module so it now supports new block syntax

    Examples

    in vhost conf file outside of server {} context
    Code:
    lua_package_path '/usr/local/lib/lua/resty/?.lua;;';
    
    server {
    in actual vhost conf file's server {} context

    Code:
         location /lua_content {
             # MIME type determined by default_type:
             default_type 'text/plain';
    
             content_by_lua_block {
                 ngx.say('Hello,world!')
             }
         }
    
         location /nginx_var {
             # MIME type determined by default_type:
             default_type 'text/plain';
