Moving the MySQL's datadir directory

spirit — Thu, 03 Jul 2008 11:13:28 +0000

Steps:
   1. Stop your mysql server before starting this operation
   2. Create the directories that will be new datadir
   3. chown the directory to the mysql:mysql user
   4. copy the files from the old datadir to the new location (cp -p : preserves ownership). However, make sure that the files
       named ib_arch_log_0000000000, ib_logfile0 etc. are not copied to the newer location
   5. Make sure that the files and directories are owned by mysql user
   6. Make changes in the my.cnf to point the new datadir (datadir = /my/new/dir/)
   7. Restart the MySQL database
   8. Create a new database and verify that the files for this database are getting created in the new datadir (create database test)
   9. After the server is running for a few days properly, get rid of the old data.
