”because search permissions are missing on a component of the path“

使用 httpd 访问时，如果遇到标题描述的问题：

请关闭 SElinux 试下:

# setenforce 0

关于 SElinux 简记:
1. SElinux 有三种策略:

# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.

2. 查看
# getenforce
# sestatus


3. 策略转变
=======在线修改=======
a. enforcing --> permissive
# setenforce 0

b. permissive --> enforcing
# setenforce 1
=====================

=======重启修改=======
c. enforcing/permissive --> disabled
# sed -i s#SELINUX=.*#SELINUX=disabled#g /etc/selinux/config
# reboot

d. disabled/permissive --> enforcing
sed s#SELINUX=.*#SELINUX=enforcing#g /etc/selinux/config
# reboot

e. disabled/enforcing --> permissive
sed s#SELINUX=.*#SELINUX=permissive#g /etc/selinux/config
# reboot
=====================

4. 文件 label 查看
# ls -Z
