I'm trying to learn more about Percona. Installing Debian 7 with Percona 5.6 in VMWare, i realize I can't restart percona. Code: service mysql reload Works. But everytime I do Code: service mysql restart Percona failed to restart. I had to reboot to make percona up again. The weird thing is... when I check percona status Code: service mysql status Percona is down. But when I see... Code: lsof -i -P There is mysql runing as mysqd. Another problem, percona failed to up if I put .cnf from Percona Tools wizard. Even rebooting cannot make percona up. So... any suggestion?
