Concat working on Centmin beta09

EckyBrazzz · Oct 3, 2019

Is this still working on beta09?

Concat | NGINX

As described here : Nginx - CentminMod.com LEMP Nginx web stack for CentOS

Code (Text):

    location /css {
       concat on;
       concat_max_files 20;
   add_header Pragma public;
   add_header Cache-Control "public, must-revalidate, proxy-revalidate";
   access_log off;
   expires 30d;
       }

       location /js {
       concat on;
       concat_max_files 20;
   add_header Pragma private;
   add_header Cache-Control "private, must-revalidate, proxy-revalidate";
   access_log off;
   expires 30d;
       }

This isn't advisable on HTTP/2 usage.

EckyBrazzz · Oct 3, 2019

Hmm, better tell @eva2000 to remove that part from the page Nginx - CentminMod.com LEMP Nginx web stack for CentOS because it's a bit outdated.

Although, some things I do against the HTTP/2 best practice give me better results on some sites.

last i checked it still worked though you'd have to test whether it's beneficial to your specific assets you're loading over HTTP/2 HTTPS

i don't use concat nginx module much as only time you can use it is if you can control and know what css/js files are being served i.e. very static site as opposed to dynamic scripted sites where web app generates the css/js url and/or cache breaking query strings

Tested it but ain't working anymore.

Code (Text):

=========================================
nginx -t
nginx: [emerg] unknown directive "concat" in /usr/local/nginx/conf/conf.d/domain.com.ssl.conf:125
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed

does nginx -V show concat module ? would need nginx upgrade log to see if nginx upgraded/recompiled with it Install - Nginx - How to troubleshoot Nginx installs/upgrades when you set NGINX_HTTPCONCAT='y' in persistent config file /etc/centminmod/custom_config.inc prior to centmin.sh menu option 4 recompiles of nginx. By default NGINX_HTTPCONCAT='n' is set. Guess need to update documentation at https://centminmod.com/nginx.html#httpconcat as 123.09beta01 changed it to disabled by default unlike previous versions

according to centmin.sh's commit blame history NGINX_HTTPCONCAT was set to n 4yrs ago

set NGINX_HTTPCONCAT='y' in persistent config file /etc/centminmod/custom_config.inc prior to centmin.sh menu option 4 recompiles of nginx will show --add-module=../nginx-http-concat-master in nginx -V output

Guess I need some new glasses to read, did read in my nginx -V --with-compat. Just a letter

Compile it with the NGINX_HTTPCONCAT='y' now.

EckyBrazzz · Oct 6, 2019

Well, it works, got super fast loading times... But better keep with old settings, as it breaks some parts of the site I tested it. (slider and some other options) But the slider was always a problem on this site. Think going to replace it with a other slider.
