I´m trying to migrate a mysql database from an old drive which had fedora9 (which did not boot anymore) to an ubuntu 16.04 server.
I copied the /var/lib/mysql folder from the old system to /testdb/mysql in the new system.
I change the owner to mysql:mysql to the new folder and update datadir of my.conf to this new folder, but the mysql server does not boot anymore. I get the following error:

I tried to change all permissions, even 777 to all files (only to try it), but always have the same result.
How can I recover the databases?
I finally found the way to recover the tables, and it is not changing the datadir from my.conf (it didn´t work, even copying the content of the default database that works fine), I copied the folder I want to recover to the default datadir, overwriting all files except mysql.sock and mysql folder.
Then I started the mysql server and it works, but some tables shall to be repaired with
mysqlcheck --repair --all-databases -u root -p
Now everything works fine

I have googled a lot about this issue though there are some solution available however I tried all of them and seems that my issue is slightly different.

llja is right. I made the same mistake. To start mysqld, simply type
mysqld

I've tried chmod 777 and chown mysql:mysql to the mounted folder (/var/www/html/DB/) but the result is same. After using chown, I can even see that the owner is now mysql. So why MySQL is failing to access the folder?
I've seen similar question here but most of the accepted answers are reinstalling MySQL. That's not a solution to me. It's simply bypassing the problem. Any better answer?
Can you check that you have set all your config file where you have to change directory path in my.cnf
Also make sure you have change the profile for mysqld that mean you have to update AppArmor config file so it will get the new directory.
Check this link https://blogs.oracle.com/jsmyth/entry/apparmor_and_mysql
I hope this will work!!
I installed MySQL through a package located in MySQL site.
I changed this directory:
/usr/local/mysql-5.5.28-osx10.5-x86/data
For _mysql
However, when I try to do mysqld start, I get the following errors and warnings:

Any tips on what can be happening?
The easiest thing to do is to install the System Preferences plugin that you get with the download and start/stop MySQL using that. You can set it there to start automatically when the system restarts.
I have installed mysql on windows 7 environment.
When I attempt to start the server from command line
as: mysqld --user=root
I get following message:

Try this:
Run Windows CMD Prompt as an Administrator and execute your MySql command.
