Currently I am working on Fedora 21. I want to install Percona server but it seems it does not support for community version. Is there any workaround for this??
You'll be fine to download the RPMs from Percona.com
Untar the archive and perform the install using YUM so that Fedora can satisfy any dependencies;
bash-4.3# cat /etc/issue
Fedora release 21 (Twenty One)
Kernel \r on an \m (\l)
bash-4.3# yum install -y Percona-Server-server-57-5.7.11-4.1.el6.x86_64.rpm Percona-Server-client-57-5.7.11-4.1.el6.x86_64.rpm Percona-Server-shared-57-5.7.11-4.1.el6.x86_64.rpm
bash-4.3# rpm -qa | grep -i percona
Percona-Server-shared-57-5.7.11-4.1.el6.x86_64
Percona-Server-client-57-5.7.11-4.1.el6.x86_64
Percona-Server-server-57-5.7.11-4.1.el6.x86_64
