centos6.2，停滯mysqld然後修正/etc/my.cnf datadir的地位，啟動mysqld提醒FAILED，檢查日記

新的datadir途徑確切沒成績，並且目次和目次下一切文件都是777權限，下層目次也有rx權限，只不外datadir和部屬文件owner都是root（由於我用虛擬機掛載的windows的文件體系）。後來想到應當是selinux弄的鬼，設置為permissive形式以後正常啟動mysqld。
[root@data selinux]# getenforce
Enforcing
[root@data selinux]# setenforce 0
[root@data selinux]# getenforce
Permissive
setenforce 1 設置SELinux 成為enforcing形式
setenforce 0 設置SELinux 成為permissive形式
完全封閉，vi /etc/selinux/config 修正 SELINUX=disabled
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
