For a database named "lbry", try this:

mysqldump -u root -p lbry > dump-lbry.sql

Create a database of the same name ("lbry" in this example) on the computer to which you wish to copy the database contents

Then import it:

mysql -u root -p lbry < dump-lbry.sql

You can do by this process step-by-step using MySQL WorkBench.

1. Install MySQL Workbench


2. Connect to existing Database


3. Go to Navigator -> Management -> Data Export.
   (this will dump queries of tables one by one in a separate folder, Workbench uses the same folder to import)


4. Create Database on target PC.


5. Connect to Target Database (would consist of 0 tables in DB)


6. Go to Navigator -> Management -> Data Import/Restore.
   (this will use the dump folder and create tables in your target Database).

Hope this helps.

The only SAFE way to copy databases from one machine to another is to first quiesce the database (make sure no clients are modifying it), then use the mysqldump command to create a text representation of your schema and the contents of your tables. Then copy that text file over to the other machine and read it in by specifying it as the input to the mysql command.

Attempting to copy the actual mysql data directories over is asking for trouble, since they are dependent on the architecture of the machine that mysql is running on and likely on the version of mysql and whatever storage engine is in use.
