Move MySQL database location

MySQL DB might using some location as data repository where hard-disk space is limited. This will warrant moving the data from that location to some other location which can provide more room to accomodate the increasing data. Following steps can move this data to the new location:


du -h : will show the memory parition of the current folder

--------------------


-->> Set the password for mysqlmanager (required if password is not set already).
mysqlmanager --passwd >> /etc/mysqlmanager.passwd

--> log into mysql manager
mysql -uroot -psh*pp@r --socket=/tmp/mysqlmanager.sock

-->> kill all instances of mysql
ps afx | grep mysql //get process ids
kill -9 4465 4473 4474 // kill those processes

-->> create the directory where you want to transfer the files
mkdir /mnt/mysql/marketingportal

-->> Give mysql the ownership of the directory and its contents (presently they are owned ny root)
chown -R mysql.mysql /mnt/mysql/ //mysql.mysql : group:user

--> Open the folder where the current data is
cd mysql-marketingportal/

--> Copy this data to the new folder
cp -R * /mnt/mysql/marketingportal/

-->> Give mysql the ownership of the new directory and its contents (presently they are owned ny root)
chown -R mysql.mysql /mnt/mysql/ //mysql.mysql : group:user

-->> Change the name of the old directory (optional - this is done to make sure that it isn't beign used any longer)
mv mysql-marketingportal/ mysql-marketingportal-old/

-->> edit the my.cnf file
change the value of datadir

-->> Start the mysqlmanager
nohup mysqlmanager --user=mysql > mysqlmanager.out &
