7.3php missing extension mysqlnd

Help
1

Updating my php from 7.2 to 7.3. When I change /etc/nginx/conf.d/librenms.conf so it’s pointing to 7.3 location and restart nginx I get a missing php extension “mysqlnd” window when I refresh the page. What’s the best way to resolved?

I was able to install the mysql php extension and I now have my connection to the database again. However I have a new set of errors. I’ve installed each extension below by doing: apt install php-mbstring, apt install php-xml, apt install php-dom, but still no joy, instead it created a php7.4 folder and put the extensions in there but I’m running 7.3 so I’m not sure why that happened.

OMG!!! I didn’t specify 7.3 when I installed the extensions. Once I did that my validate checks out.
