Solution to the error "unable to move uploaded files to" in WordPress _ PHP-php Tutorial

This article mainly introduces how WordPress cannot move uploaded files to an error. the environment in this article is based on the Linux system and Nginx server, if you want to upload images to a blog today, you can refer to the following message: "You cannot move the uploaded file to/home/wwwroot/wp-content/uploads/2013 /", depressed, I think it is a permission issue. I changed all my files to 777 permissions, but I still cannot write them, and images cannot be uploaded.
Simply, I checked the permissions of the root directory folder of my website, and the permissions are www and www, while ps aux | grep nginx displays the nginx subroutine running as nobody, ps aux | grep php-fpm, also displays nobody. At the same time, I found that the permissions for other files and folders on my website are root and root. This may be because I copied the file directly as the root user last time. Therefore, the root file cannot be modified as the nobody user.
The method is as follows:
Step 1:
First, the running identities of nginx and php-fpm subprograms are changed to www, and the user group is also changed to www.
Modify the nginx. conf file and change user nobody to user www;
Run the following command:

Service nginx restart // restart nginx

Modify the php-fpm.conf

  user = nobody  group = nobody

Changed:

  user = www  group =www

Run the command: service php-fpm reload // restart php-fpm
Step 2:
Modify all folders and files to www, www

#chown -R www:www /wwwroot

Upload the image again, prompting you that the upload is successful and the problem is fixed.
There are also some other methods on the Internet, such as changing the image to the English name or the folder to 777. In fact, in many cases, the permission is 777, but it still cannot be uploaded. you can consider whether it is the file owner.
