解答

什么原因导致这些错误呢?原凶就是在安装LINUX时开启了SELinux,记得关闭SELinux

解决方法:

(1)查看selinux的状态为Enforcing模式(setenforce 1设置SELinux 成为Enforcing模式,即开启SElinux)

[root@mydb]# getenforce

Enforcing

(2)setenforce 0 设置SELinux 成为permissive模式(即临时关闭SElinux)

[root@mydb]# setenforce 0

(3)查看selinux的状态为Permissive模式(setenforce 0设置SELinux 成为Permissive模式)

[root@mydb]# getenforce

Permissive

5、查看Selinux的配置文件是否修改

[root@mydb bin]# vi /etc/sysconfig/selinux

# 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 - SELinux is fully disabled.

SELINUX=disabled

# SELINUXTYPE= type of policy in use. Possible values are:

#       targeted - Only targeted network daemons are protected.

#       strict - Full SELinux protection.

SELINUXTYPE=targeted
