Ngx_PageSpeed on my centOS 8 - nginx: [emerg] unknown directive "pagespeed"

[Paolo]

I ran this code:

1. bash <(curl -f -L -sS https://ngxpagespeed.com/install) \ --nginx-version latest

2. ln -s /usr/local/nginx/conf/ /etc/nginx

3. ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx

4. vi /etc/init.d/nginx and inserted this script:https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/

5. systemctl start nginx +  systemctl enable nginx + # systemctl status nginx

6. Added on my nginx.conf this script:
   

   # Pagespeed main settings
   
   pagespeed on;
   pagespeed FileCachePath /var/ngx_pagespeed_cache;
   
   
   # Ensure requests for pagespeed optimized resources go to the pagespeed
   # handler and no extraneous headers get set.
   
   location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
   location ~ "^/ngx_pagespeed_static/" { }
   location ~ "^/ngx_pagespeed_beacon" { }

and receive this messagge:

nginx: [emerg] unknown directive "pagespeed" in /etc/nginx/conf.d/examplepagespeed.com.conf:12

this is my output:

Hi

You have 2 nginx installations, 1 version 1.14.1 and other version 1.18.0. Your system is starting the cersion 1.14.1 that don´t have the pagespeed module, so this throw the error that th directive pagespeed in your nginx.confile is unkow.

The step 4 is unneeded, nginx is started/stoped with systemd not by init ( you started nginx and make it enabled in step 5)

The systemd service files for nginx are pointing to the nginx version 1.14.1
