Nginx

Nginx is a webserver working very well on small systems

nginx -t

Test configuration

nginx -V

Print version, compiler version and configured parameters

Tips

1. Put al customizations in your site-definitions (in ./sites-available) or in .conf files in the ./conf.d subdir. This make it easier to migrate your configuration to another server.

PHP support

To enable php suppport in ./sites-available/xxx put this

 location ~ \.php$ {
       #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
       include snippets/fastcgi-php.conf;
       fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
       fastcgi_intercept_errors on;
       fastcgi_param HTTPS on;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       fastcgi_param SCRIPT_NAME     $fastcgi_script_name;
   
   }

Force clients to use https (HSTS)

Add to ./conf.d/myconfig.conf

add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

Wipe browser history for the HSTS websites if HSTS settings were disabled but the max-age has not passed yet for your browser (31536000 seconds is 1 year).

Issues and fixes

could not build server_names_hash, you should increase server_names_hash_bucket_size: 32

Due to many servernames in a server definition. In a .conf file in /etc/nginx/conf.d put a line like

server_names_hash_bucket_size 64;

Using listen [::]:80 ipv6only=on;

The ipv6only parameter can be set only once. If you have several virtual host you should not use it.
