Exporting the Legacy Database - CustodesTechnologia/System Wiki
Export the Legacy Database
Determine the name of the databases to export. For the Invision software, there should just be one database.
For this, let
DB_NAME be the name of the database to export.
$ mysqldump -u ... \ --events \ --routines \ --single-transaction \ --triggers \ old_db \ -p > sample.sql
A brief explanation:
-u rootuse the username
-pprompt for the password.
--triggersmake sure to export the stored events, routines and triggers that are in the database (if any)
--single-transactioncause the dump to be a snapshot of the database when the export starts.
old_db is the name of the database being extracted.
Application of the export
To apply the export, the process is quite simple since the
sample.sql file contains all of the SQL statements to produce the effect.
On the new destination Server:
$ mysql -u ... -Dnew_db -A -p < sample.sql
Note that the
new_db is necessary if there already exists a copy of the database on the destination server.
Note that the
mysql tables that store users, and granted privileges are not in the export.
User and Privileges
How to create the user if it doesn't already exist.
mysql> CREATE USER 'jeffrey'@'localhost' IDENTIFIED BY 'password';
If the name of the database is
db1, then this is how the user is granted access to the database:
mysql> GRANT ALL ON newdb.* TO 'jeffrey'@'localhost';
Then cause the grant tables to be reloaded.
mysql> FLUSH PRIVILEGES;
