I badly need help, I just want to say first that I am a newbie with web server. My boss was asking to me to upgrade our web server to the latest version UBUNTU 20.04 LTS as the old was running with 14.04 ( pretty old). I've installed the distribution and LAMP Stack on my desktop as I would like to try it first with my own computer before touching the server. I've installed Apache2, PHP7.4.3 and mySQL 8.0 however the versions running on the old server are really old PHP5 and mySQL5. I've copied all the files, var/www/ and config etc/apache2 then created an sql dump and migrated to the the new mysql database (I made sure that permissions are the same with the old server). However, after all the hours of research and migration it was to no success. Everytime I load localhost it's only giving me an error message;
Database Error: Unable to load Database Driver: mysqli
and my mysql database says:
Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A
Please, at this point I will really appreciate any advise or help that you can give me. I've been working on this migration for weeks now.
