Re: How to change mysql default database directory
Absolutely, check for the variable datadir on the config file (my.ini on windows and my.cnf on *nix).

Re: How to change mysql default database directory
Hi, For Linux:*How to change the mysql database location* 1. Create the directory that will be the new datadir. ( example: /home/db ) 2. Change ownership of new folder to the mysql user and group: sudo chown -R mysql:mysql /home/db 3. Stop the MySQL database server: sudo /etc/init.d/mysql stop 4. Now you need to edit the /etc/mysql/my.cnf file 1. sudo nano /etc/mysql/my.cnf 2. look for “datadir = /var/lib/mysql” and change it to datadir = /home/db 5. copy the files from the old datadir to the new location. However, make sure that the files named ib_arch_log_00, ib_logfile0 etc. are not copied to the newer location. 6. Make sure that the files and directories are owned by mysql user. If not: sudo chown -R mysql:mysql /home/db/* 7. Restart the MySQL database server: sudo /etc/init.d/mysql start Hope you find this helpful.

Re: How to change mysql default database directory
As Carlos said, mention your required path in the my.ini file and restart the MySQL or move your current datadir to your required path and restart MySQL by mentioning the variable as below in the configuration file. Datadir=path In MySQLD section of your cnf file.

Re: How to change mysql default database directory
As Suresh and others said, you have to stop the dbms, move to content of the dir and restart the dbms. Also, if you have a fresh install, innodb tables will be saved on a datafile inside the same data dir, but if is not a fresh install you may have innodb variables (ie. innodb_data_home_dir) in the config file, and you may need to change those too.

Re: How to change mysql default database directory
Carlos - Follow the below steps 1) stop the mysqld service 2) copy the current datadir to your required location ex : D:\\datadirpath 3) Edit the my.ini by placing the option in mysqld section as datadir=D:\\datadirpath 4) save the my.ini 5) start the mysqld service It will use your new datadir and the newly created and old databases use the same datadir Thanks Suresh Kuna MySQL DBA On Fri, Jan 29, 2010 at 9:22 AM, Carlos Proal carlos.pr...@gmail.comwrote: As Suresh and others said, you have to stop the dbms, move to content of the dir and restart the dbms.
