centos6.2,停止mysqld然后修改/etc/my.cnf datadir的位置,启动mysqld提示FAILED,查看日志

新的datadir路径确实没问题,而且目录和目录下所有文件都是777权限,上层目录也有rx权限,只不过datadir和下属文件owner都是root(因为我用虚拟机挂载的windows的文件系统)。后来想到应该是selinux搞的鬼,设置为permissive模式之后正常启动mysqld。
[root@data selinux]# getenforce

Enforcing

[root@data selinux]# setenforce 0

[root@data selinux]# getenforce

Permissive

setenforce 1 设置SELinux 成为enforcing模式
setenforce 0 设置SELinux 成为permissive模式

彻底关闭,vi /etc/selinux/config 修改 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
