centos6.2,停止mysqld然后修改/etc/my.cnf datadir的地位,启动mysqld提示FAILED,查看日志
MYSQL数据库
代码以下:

新的datadir路径确实没问题,并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.
代码如下:
[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MYSQL数据库
彻底封闭,vi /etc/selinux/config 修改 SELINUX=disabledMYSQL数据库
代码以下:
# 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
