问题
This is the first time i am working with wordpress and i am a bit confused about this requirement.A weird requirement by the plugin indeed Its asking me to :
Files and directories could not be automatically created to complete the installation. Please enter FTP details below to complete the setup. Also try chmod 777 /var/www/my-project/wp-content
Well i am not sure that its safe to give permission 777 to my wp-content folder. It is really required?
回答1:
Dont worry !!!! It is not asking permanently.You have to give this permission for the installation time only as it have to write things in your wp-content.After installation it will tell you to make it back to the default 755.Probably the massege will appear like this in your case.
/var/www/my-project/wp-content is write-able. When finished installing the plugin, change the permissions back to the default: chmod 755 /var/www/my-project/wp-content. Permissions are currently 777
So start installing. and be happy :-)

I idea is that you set 777 permission on the wp-content dir while you do the install and then revert the permissions.
