Question Nginx FastCGI microcaching

[Émerson Felinto]

Enable Nginx FastCGI microcaching

I really need to enable this feature for my clients. I tried to do it manually but nothing I did worked out, I also do not know how to tell if microcaching is actually active on my site.
There are already questions in the forum related to this, but nobody gave a solution that works to activate microcaching in Plesk, someone who has already managed to install and configure has some solution?

Interesting question. Here is an attempt to provide support - no guarantee on this, though. I did not test it and have not done it before.

You need to put these commands before and into the "server" brackets of /etc/nginx/plesk.conf.d/server.conf like this:

proxy_cache_path /tmp/cache keys_zone=cache:10m levels=1:2 inactive=600s max_size=100m;
server {
   proxy_cache cache;
   proxy_cache_valid 200 1s;
   # ...
}

and restart Nginx aftwards. (Example taken from Nginx documentation).

However, the /etc/nginx/plesk.conf.d/server.conf is auto-generated by Plesk. It is probably necessary to create a user template for this file to have these global changes applied to Nginx. The default configuration template for this should be /usr/local/psa/admin/conf/templates/default/nginx.php. The default should NOT be modified. Instead, copy the default to /usr/local/psa/admin/conf/templates/custom/ (the "custom" directory needs to be created for that if it does not yet exist) and edit the custom version of nginx.php there. Now after your custom nginx.php including the special microcaching directives exists, run
# /usr/local/psa/admin/sbin/httpdmng --reconfigure-all
to have Plesk rebuild all configuration files. (I am not aware that it is possible to limit the rebuild process to only the Nginx global files.)

I did everything as described, but it just is not working. Is there any way to know Microcaching Nginx is active? I put it to the server to report in the HTTP headers, but it just does not seem to work:

<?php echo $VAR->includeTemplate('server/nginxVhosts.php', array(
