Can’t find Nginx.please

Hello @alexliii

Thank you for reaching out and I am happy to assist you with this.
To confirm, have you restarted the Nginx as suggested by the W3TC notification?
In performance>Install, you can find all the rewrite rules (depending on the configuration), there you can also see the path to the nginx.conf file that W3TC should be using for those rewrite rules.
It would be best if you could share the website URL and let me know which settings are enabled in the W3 Total Cache, like Page Cache, and which settings are in the Browser Cache so we can check if the W3TC is adding necessary headers.

Alternatively, you can copy and paste the rewrite rules in Performance>Install to the nginx. conf in the path as suggested by the W3TC Install page.

Thanks!

Hello,

Upon your suggestion: Alternatively, you can copy and paste the rewrite rules in Performance>Install to the nginx. conf in the path as suggested by the W3TC Install page.

Which one nginx.conf do you mean please here? I can find there is a nginx.conf created by W3 in /var/www/lovcour.com/htdocs, and the rules already there, and here is screenshot at https://prnt.sc/jtCnx16jkSsM

Or, do you mean I should include those rules to some nginx.conf, and please note here is structure of our Nginx configuration:

/etc/nginx/sites-available/site.tld

server {

    # Uncomment the following line for domain mapping

    # listen 80 default_server;

    server_name mysite.com *.mysite.com;

    # Uncomment the following line for domain mapping

    #server_name_in_redirect off;

    access_log /var/log/nginx/mysite.com.access.log rt_cache;

    error_log /var/log/nginx/mysite.com.error.log;

    root /var/www/mysite.com/htdocs;

    index index.php index.html index.htm;

    include common/wpfc-php81.conf;

    include common/wpsubdir.conf;

    include common/wpcommon-php81.conf;

    include common/locations-wo.conf;

    include /var/www/mysite.com/conf/nginx/*.conf;

}

Looking forward to your reply.

By the way, Nginx fastcgi cache is enabled now.

Should I rename the nginx.conf( in /var/www/lovcour.com/htdocs/nginx.conf) to be Nginx_W3.conf

Then, include it into the directory at /etc/nginx/sites-available/site.tld ?

Then, it will be look like this way:

/etc/nginx/sites-available/site.tld

server {

    # Uncomment the following line for domain mapping

    # listen 80 default_server;

    server_name mysite.com *.mysite.com;

    # Uncomment the following line for domain mapping

    #server_name_in_redirect off;

    access_log /var/log/nginx/mysite.com.access.log rt_cache;

    error_log /var/log/nginx/mysite.com.error.log;

    root /var/www/mysite.com/htdocs;

    index index.php index.html index.htm;

    include common/wpfc-php81.conf;

    include common/wpsubdir.conf;

    include common/wpcommon-php81.conf;

    include common/locations-wo.conf;

    include /var/www/mysite.com/conf/nginx/*.conf;
    
    include common/Nginx_W3.conf

}

Hello @alexliii

Well, this means that the W3TC rules are where they need to be and everything is working as expected. The W3TC uses the nginx. conf in the root of your website and as you suggested, all the rules (according to the configuration) are there.
You should not rename that file because this is the Nginx configuration file!

Thanks!

Sorry, I am confused, how does Nginx use that ngnix.conf(/var/www/lovcour.com/htdocs/nginx.conf)created by W3?

I did not find where it was included in our Nginx configuration (/etc/nginx/sites-available/site.tld?)

Also, I did not find any info of W3 cache in the header, did you checked our website?

Hello @vmarko,

I did not find Nginx.conf by W3 was included in sites-available/site.tld?, would you please clarify how it works with Ngin?

Thanks

Hello @alexliii

The WordPress is installed in the /htdocs/ The nginx.conf file there is handling the rules for your website as you have seen in the screenshot you shared.
As you can see, there are rules for page caching (because you are using Disk Enhanced) and Browser Cache.
When inspecting the source and check the files on your website I can see the headers:

1. cache-control: max-age=3600, public
2. content-encoding: gzip
3. date: Wed, 18 Jan 2023 12:27:01 GMT
4. etag: “b070a9e9e25f398a182fce9a086e7bb9”
5. last-modified: Wed, 18 Jan 2023 12:27:01 GMT

This means that the options enabled in Browser Cache like Cache-control, gzip, etag, etc are set.
So the only ngix.conf W3 Total Cache can use is the one mentioned above, the other nginx configuration files cannot be modified by the W3 Total Cache.
This is a normal behavior.

Thanks!
