Beta Branch Centmin Mod Nginx + Lua + LuaJIT support preview / discussions

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

checking if luaJIT installed in vhost.conf add to server{} context

Code (Text):

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

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 (Text):

branchname=123.08beta03
 

Step 2.

Actual install

Code (Text):

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 (Text):

./centmin.sh
 

or for CLI install mode

Code (Text):

./centmin.sh install
 

update: Easy to try a new branch via git see Upgrade - Working with git command line for updating Centmin Mod local copies | Centmin Mod Community

 

Very easy to switch or update or downgrade Centmin Mod branches via git - see how I switched between 123.08lua and 123.08centos7beta02 branches at Upgrade - Working with git command line for updating Centmin Mod local copies | Centmin Mod Community

 

Just updated 123.08lua branch with luajit git repository dev branch support as 2.1.0* branch has better performance than 2.0.4 stable. Also moved luajit install to dedicated inc/luajit.inc include file too.

split off a dedicated discussion and feedback thread for Centmin Mod's planned Nginx + Lua + LuaJIT support

 

Centmin Mod 123.08beta03 is now available - 123.08beta03 branch is the merging of the 3 branches - .08 beta 02 + 123.08lua + 123.08livestats so the new beta has both Nginx Lua + LuaJIT support + new Nginx vhost traffic statistics

feedback for Nginx Lua related stuff can be posted in this thread

 

Well I only add the Nginx Lua support - how to use it and what for is up to you

 

LuaJIT

LuaJIT benchmarks Performance: x86/x64

JIT = Just-in-time compilation - Wikipedia, the free encyclopedia

 

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

Code (Text):

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

 

Nice usage case for Nginx Lua Beta Branch - Centmin Mod .08 beta03+ Multiple PHP-FPM pools support added | Centmin Mod Community

 

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 (Text):

lua_package_path '/usr/local/lib/lua/resty/?.lua;;';

server {

in actual vhost conf file's server {} context

Code (Text):

     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';

         # try access /nginx_var?a=hello,world
         content_by_lua_block {
             ngx.say(ngx.var.arg_a)
         }
     }

    location = /lua {
        default_type text/plain;
        content_by_lua_block {
        if jit then
            ngx.say(jit.version)
        else
            ngx.say("Not LuaJIT!")
        end
        }
    }
 

Code (Text):

curl localhost/lua_content
Hello,world!

curl localhost/nginx_var?a=hello
hello

curl localhost/lua
