Methods for filtering out certain databases during full mysql backup, mysql backup Filtering

Mysql uses the -- all-database parameter for full backup.

For example:

# Mysqldump-u root-h localhost-p -- all-database>/root/all. SQL

When importing data, you can log on to the mysql database and use source/root/all. SQL to import the data.

Problem:

To filter out some databases when mysqldump backs up the database.

In this case, -- all-database cannot be used for mysqldump backup, but -- database is used.

When backing up a database:Filter out the information_schema, mysql, test, and jkhw_db databases.
