Backup MySQL users

Question

How do I backup MySQL users and their privileges?

Anything like mysqldump?

I am looking for something like:

mysqldump -d -u root -p MyTable > Schema.sql 

Answer 1

mysql -BNe "select concat('\'',user,'\'@\'',host,'\'') from mysql.user where user != 'root'" | \ while read uh; do mysql -BNe "show grants for $uh" | sed 's/$/;/; s/\\\\/\\/g'; done > grants.sql 

Answer 2

You can backup mysql database using

mysqldump -u root -p mysql > mysql.sql 

and restore mysql database by executing

 mysql -uroot -p mysql < mysql.sql 

Dont forget to

FLUSH PRIVILEGES

after restoring dump.

Hope it helps...
