Server Fault Asked by 0LEg on December 9, 2021
Well… I know there are so many simular questions asked. But in order to make this post to be somehow userful for community once being solved I would like to list up a working Nginx + PHP-fpm conf files for WordPress. But as of now It dosn’t work, he he.
As that is my second time dealing with Nginx (fisrt set up was with close to default settings) configuration I’m afraid I can not handle troubleshouting wihtout help.
What I’m tring to do is to set up Nginx with FastCGI cache in order to kick WordPress’ butt to make it run faster.
Right after install nginx was able to show default greeting html page while adressing http://vps_ip_adress
. I guess that means networking and basic set up is fine.
Then I installed php7.4-fpm and tune a bit nginx configuration to enable FastCGI cache for futher WordPress install. For testing purpose I put info.php file containing <?php phpinfo(); ?>
into sire root dir /var/www/html/mysitename/info.php.
Now I’m getting FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream
in nginx error log. I already read that it means php-fpm can not locate scripit, most likely due to wrong scrip name somthere in nginx configuration. Unfortunately being not expirienced with nginx I can not locate the error.
As a reference I used nginx configuration found on internet (yeah… I know, problem with stuff found in internet – it never work he he). In case if with someonce’s help I’ll get it working here will be listed Nginx+PHP-fpm set up with FAstCGI cache which is quite demanded I guess. Any advices of how to iptimize nginx+php-fpm configuration for WordPress wil be much appreciated.

Some highlights from that file (it is pretty long…)
user = www-data
group = www-data
listen = 127.0.0.1:9000
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
Could you please help me in troubleshooting?
Finally I made it work with the following set up... Here goes configuration which works for me.
