Configuring Nginx+Apache for ISPConfig 3 on Debian 11 server

No. phpmyadmin is on port 8081. e.g. https://yourserver.tld:8081/phpmyadmin

.htaccess is an apache specific file and file format that is not used by other http servers like Nginx. Nginx has its own rewrite rule syntax. see Nginx documentation: https://nginx.org/en/docs/

You can put website-specific rewrite rules into the Nginx directives field of the website in ISPConfig, this field is on the options tab of the site. As an example, here are the rules for a WordPress website:

Code:

location / {
                try_files $uri $uri/ /index.php?$args;
       }

       # Add trailing slash to */wp-admin requests.
       rewrite /wp-admin$ $scheme://$host$uri/ permanent;

       location ~*  \.(jpg|jpeg|png|gif|css|js|ico)$ {
                expires max;
                log_not_found off;
}

Websites send emails via PHP, the web server apache or nginx is not involved in that at all. The web server can send email on its own if you installed ISPConfig will mailserver option, but you can also specify a proxy in ISPConfig. But as mentioned already, that's not webserver specific.

 

Do not change any files in that folder manually, any manual change will get removed automatically on the next update unless you make it in an update-safe way by using custom template files. Instead of changing the port, set the URL for the button to access phpmyadmin to that URL. You can find the setting under system > interface > main config. Enter the full URL there, starting with https://

 

From post #22: "You can put website-specific rewrite rules into the Nginx directives field of the website in ISPConfig, this field is on the options tab of the site." So to make WordPress work for any client, you add this in any client's nginx directives field. And for easo of use, use System > directive snippets to define a WordPress specific snippet there.

Has been answered already as well, from post #25 "Do not change any files in that folder manually". And the file /etc/nginx/sites-available/default is not related to any hosted website, same as with apache btw.

If you host WordPress sites only and you want that no other CMS will work on your system, then you can alter the main nginx vhost config file template by copying the file /usr/local/ispconfig/server/conf/nginx_vhost.conf.master to /usr/local/ispconfig/server/conf-custom/nginx_vhost.conf.master and then alter the file /usr/local/ispconfig/server/conf-custom/nginx_vhost.conf.master
This file gets applied to any new or updated website.

 

By manually running apt-get install to install phpmyadmin, a post which you have hidden in this thread now, you overwrote the phpmyadmin installed by ISPconfig from source and therefore you downgraded phpmyadmin on your system to the version that ships with the OS. So your phpmyadmin setup was fine until you overwrote the version installed by ISPConfig.

 

A newer phpmyadmin as deb package might be available from backports repo too.
