How to solve a Linux permission issue for opencart

问题

I had used subversion to revert my PHP Opencart project, but I got a permission issue (sample shown below:

Warning: imagejpeg(): Unable to open '/var/www/html/opencart/image/cache/data/pavblog/img-blog-620x300w.jpg' for writing: Permission denied in /var/www/html/opencart/system/library/image.php on line 45

Warning: imagejpeg(): Unable to open '/var/www/html/opencart/image/cache/data/pavblog/img-blog-250x250w.jpg' for writing: Permission denied in /var/www/html/opencart/system/library/image.php on line 45

Warning: imagejpeg(): Unable to open...

I executed the below commands to add permissions to these folders, but I'm still getting the warning messages on my site.

sudo chmod 777 /var/www/html/opencart
cd /var/www/html/opencart 
sudo chmod 777 image/ 
sudo chmod 777 image/cache/ 
sudo chmod 777 image/data/ 
sudo chmod 777 system/cache/ 
sudo chmod 777 system/logs/ 
sudo chmod 777 download/ 
sudo chmod 777 config.php
sudo chmod 777 admin/config.php

How can I fix this?

回答1:

You need to apply permissions recursively. Try

sudo chmod -R 777 image/cache/

回答2:

To fix your permissions, you'll need to take two different steps:

Grant permission to the proper entity. Since you're in /var/www/html, my guess is that the correct user is "apache".

# Grants permissions to apache
sudo chown apache:apache -R /var/www/html/opencart

# If that doesn't work, perhaps try www-data
sudo chown www-data:www-data -R /var/www/html/opencart

Set the permissions of files and folders properly (it can be dangerous for files to have execute permission)

# Sets directory permissions to 755 (rwxr-xr-x)
sudo find /var/www/html/opencart -type d -exec chmod 755 {} \;

# Sets file permissions to 644 (rw-r--r--)
sudo find /var/www/html/opencart -type f -exec chmod 644 {} \;
