PHP 操作文件没有权限：Permission denied

PHP 操作文件没有权限：Permission denied    

apache2 log中总是看到这样的提示,终于想明白了,用户改为www-data解决问题.

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

• 1

#
# 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 www-data:www-data your_folder
#chmod -R 755 your_folder
