Chown在我的Web服务器上不起作用

Question

I get an issue using sudo chown -R www-data:www-data /var/www on my web server (ubuntu 14.04).

My NodeJS application is using the fs module and when I want to edit a json file it works only if I do a sudo chmod 0777 myfile , with the chown it doesn't work...

Any ideas?

Answer 1

The chown command made the user www-data the owner of the files in /var/www , which means that to get full (r/w) access to those files you either have to run your Node app as that user as well ( sudo -u www-data 'pm2 start ...' ), you have to adjust the permissions on the file(s) so that your regular user id can write them (like you found out after chmodding them to 0777), or you have to chown the files to your regular user id (but there's probably a reason why you chowned them to www-data in the first place).

I would opt for the first solution (using su ).
