PHP 操作文件没有权限:Permission denied

问题

在本地使用PHP脚本操作文件可以成功,等放到服务器上就不行。
查看apache日志:

#cd /var/log/httpd
#tac error_log

显示:

cannot create directory '_TEST1': Permission denied

解决

1.查看apache配置的用户和用户组

#vi /etc/httpd/conf/httpd.conf
#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User  apache
Group apache

可以看到User和Group 都是 apache。

2.修改你要操作的文件夹用户和权限,将用户就改为和apache配置一样,将权限修改为755:

#chown -R apache:apache your_folder
#chmod -R 755 your_folder

3.按理说到这步应该问题就解决了,可是这天使用的是刚装的新系统,SELINUX 忘记关了,害我调试了一个下午,坑爹啊!!!

关闭SELINUX:

#vi /etc/selinux/config
#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
#setenforce 0 #使配置立即生效
