centos6.6 failed to start after compiling the installation mysql5.6: Starting MySQL ... error! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).

Today, when compiling and installing mysql5.6, starting MySQL appears. error! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid). It was heartbreaking at the time, before installing it well, searching for help methods on the Internet, But there is no like me, some say I did not give mysqld permission, but I gave him permission, tried a bunch of methods, finally discouraged, ready to remove MySQL reinstall, on my execution: Yum remove MySQL mysql-server mysql-libs Compat-mysql time, the progress line has been gone again, jerked to see these:
