Overview:

If the database map is corrupt for a cPanel user, you can use the /usr/local/cpanel/scripts/rebuild_dbmap script to rebuild that user’s database map.

How to call the rebuild_dbmap script

Run the rebuild_dbmap script with the following flags:

• --noop — Display the results of a test run of the function, but do not perform any changes.

  ./rebuild_dbmap example --noop
  Operating in no-op mode; no changes will be made to your system.
  
  Reading access rights for the cPanel user "example" from live data:
  MariaDB/MySQL ... PostgreSQL ... Done.
  
  Without the "--noop" flag, this script would generate and install
  the following database map data:
  
  ---
  MYSQL:
  example_database:
  - example_test
  example_test:
  - example_test
  example_test123xxxxxxxxxxxxmxmxmxmxmxmxmxmxmxmxmxmxmxmxmxmxmxmx: []
  
  example_test2:
  - example_test4
  example_wp: []
  
  PGSQL:
  example_test: []
  

• --help — Return help information.

• dbuser — The cPanel user for whom to rebuild map information.

  user1
  

For example, to rebuild the database map information for the user1 cPanel user, run the following command:

/usr/local/cpanel/scripts/rebuild_dbmap user1

If the script succeeds, you will receive confirmation from the command line that resembles the following example:

./rebuild_dbmap example
Reading access rights for the cPanel user "example" from live data:
 MariaDB/MySQL ... PostgreSQL ... Done.
Old DB map file backed up at:
    /var/cpanel/databases/example_backup_2015-07-14_17:17:49_31314.json
Old DB map file removed.
Saving: MariaDB/MySQL ... PostgreSQL ... Done!
Rebuild complete.
