How to persistently set Nginx's worker processes?

I'm trying to set worker_processes to auto, but it keeps being reverted. I know that certain directives can be set in ea-nginx/settings.json, but worker_processes doesn't appear to be one of them and setting it in conf.d/modules/*.conf doesn't take precedence from the tests I've ran. Is there any way to set that or override other core Nginx directives that are not supported in settings.json? cPanel/WHM version 11.106.0.9, Nginx version 1.23.1

  Hey there! Have you tried using the details under the Global Configuration in this section? NGINX with Reverse Proxy | cPanel & WHM Documentation This will let you create configuration files that area read globally for all accounts.

  Hey there! Have you tried using the details under the Global Configuration in this section? Core functionality Tried adding a code block here to show the top 15 lines of /etc/nginx/nginx.conf, but getting a 403 upon submitting a post reply with it. I noticed that worker_connections seems to be preserved when set to a custom setting, but worker_processes is still reverted back to 1. I had changed worker_processes to auto again and worker_connections's 1024 to 4096, but only the former was reverted. Being able to adjust this directive is a pretty integral part of configuring Nginx so I believe cPanel should look at incorporating some form of managing more of the configuration natively.

  I'm not finding much on my end for this. Could you create a ticket with our team so we can do a bit more research on this for you?

  I have the same problem. How to set Worker Processes ?? I just can have 1, like for one CPU Core. Manual says one Worker per CPU core but the setting in /etc/nginx.conf keeps reverting.

  @Thimempapa - there's no way to make that change at this time. Could you submit a feature request for that using the link in my signature?

  There"s a solution now. after contacting support, this here work for me: # cp -vi /etc/nginx/nginx.conf{,.bkp} # cat /etc/nginx/ea-nginx/settings.json { "apache_port" : "81", "apache_port_ip" : "127.0.0.1", "apache_ssl_port" : "444", "apache_ssl_port_ip" : "127.0.0.1", "client_max_body_size" : "128m", "worker_processes" : "2" } After "worker_processes" : "2" has been appended to /etc/nginx/ea-nginx/settings.json as outlined above, you would also need to rebuild the configuration: /scripts/ea-nginx config --all Then you can verify the worker_processes is retained in the NGINX configuration with the following commands: # cat /etc/nginx/ea-nginx/settings.json { "apache_port" : "81", "apache_port_ip" : "127.0.0.1", "apache_ssl_port" : "444", "apache_ssl_port_ip" : "127.0.0.1", "client_max_body_size" : "128m", "worker_processes" : "2" } # grep worker /etc/nginx/nginx.conf worker_processes 2; worker_shutdown_timeout 10s; worker_rlimit_nofile 65536; worker_connections 4096; # Modify settings.json did not work because the reconfig must be run afterwards. so the solution to edit settings.json is working very well ;)
