centos下更改目录权限后仍不可写怎么办

问题描述：

在 CentOS 上搭建环境时，无论如何修改用户权限为 777 或者 755 、变更文件所属用户， Laravel 框架总是报错 "The stream or file "/var/www/laravel56/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied"。

解决方法：

关闭selinux即可。

编辑 /etc/selinux/config 文件，将 SELINUX 项修改为：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 - Only targeted network daemons are protected. 
# strict - Full SELinux protection. 
SELINUXTYPE=targeted
