If you are on Fedora or Red Hat Box
$ setenforce 0 #disbles selinux temporarily
$ yum install mysql
If you have a rpm then
$ rpm -i /mysqlSRC_RPM_Folder/MySQL*
You can download rpm’s from http://www.mysql.org
$ restorecon -R /var/lib/mysql/ #restore selinux labels
$ setenforce 1 #enable selinux again
Now, I successfully installed MySQL. Now I wanted to change the location of where the actual data would be stored, I tried configuring the my.cnf file and using symlinks. I found using the symlinks to be easier and more compatible.
My data directory is /home/mysql.
The following is what I did to change the data directory after using RPM to install.
1. stop mysql server
2. mkdir /home/mysql
3. mv /var/lib/mysql/* /home/mysql/
4. rmdir /var/lib/mysql
5. ln -s /home/mysql /var/lib/mysql
Instead of using symlinks,we can just modify the my.cnf file (/etc/my.cnf) by including “datadir = /home/mysql”
6. chown -R mysql:mysql /home/mysql
7. start mysql server again
