How to add additional nginx directives globally on a Plesk server

Question

How to add additional nginx directives globally, so that these directives will not be overwritten after updates?

Answer

1. Connect to a Plesk server via SSH.

2. Create the directives.conf file inside the /etc/nginx/conf.d/ directory:

   # touch /etc/nginx/conf.d/directives.conf

3. Now, open the created /etc/nginx/conf.d/directives.conf file in a text editor. In this example, we use the vi editor:

   # vi /etc/nginx/conf.d/directives.conf

4. Add required directives. For example:

   # cat /etc/nginx/conf.d/directives.conf
   proxy_send_timeout 1200s;
   proxy_read_timeout 1200s;
   fastcgi_send_timeout 1200s;
   fastcgi_read_timeout 1200s;
   proxy_buffers 8 16k;
   proxy_buffer_size 32k;
   fastcgi_buffers 8 16k;
   fastcgi_buffer_size 32k;

5. Save the changes and close the file.

6. Make sure that the new directives do not break nginx configuration:

   # nginx -t
   nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
   nginx: configuration file /etc/nginx/nginx.conf test is successful

7. Reload nginx configuration to apply the changes:

   # service nginx reload
