Export and import big data mysql with mysqldump

To export big data on mysql use this command:

# mysqldump -u [username] -p [databasename] | gzip > [filename.sql.gz]

To import big data on mysql
First you must extract compress file  [filename.sql.gz] to [filename.sql]

#mysql -u  [username] -p
mysql> use [databasename];
mysql> source path/to/[filename.sql];

 If your data is too big, the import process can be used long time, wait until finished. If not you must try from Import process.

Thx.
