File Permissions

[decapper]

After I was forced to move hosting companies I have found that my file permission are all 644.

 

Does anyone know if this is correct. I have had to change a few files as oscommerce tells me too.

 

Should I leave them all at 644?

The majority of your files should be 644 except for anything that the webserver needs to be able to modify. In those cases they will need 777 permissions, which should be rare for security reasons.

The above is correct where you have an osCommerce install in a shared hosting environment, and will also work in most other environments too!

 

In my experience, if you ONLY have access via FTP to a server then you will inevitably have to set permissions to allow WORLD rights for files/directories that osCommerce needs write access to (i.e. 777 for directories, and 644 for files).

 

N.B.

Owner,Group,Other permissions are often expressed using decimal numbers, but you can work them out when you think of them as binary, each decimal number can be expressed as three binary bits corresponding to RWX (e.g. RWX = 111 = 7, RW- = 110 = 6, R-X = 101 = 5, R-- = 100 = 4, etc.).

 

In other cases where you DO have SuperUser access then you should be able to set the ownership of the files/directories and be more restrictive in permissions (e.g. on dedicated *nix/Linux hosting).

 

 

 

e.g. in a Linux environment

 

In the root of your osCommerce install:-

 

All files/directories have USER:GROUP set as <YOUR_FTP_USER>:<WEBSERVER_GROUP>

#:> chown -R <YOUR_FTP_USER>:<WEBSERVER_GROUP> *

 

All files have a minimum permissions of 644

chmod -R 644 *

 

All directories have minimum permissions of 755

chmod -R 755 *

 

All osCommerce Writable files have permissions of 664

chmod 664 <FILENAME>

 

All osCommerce Writable directories have permissions of 775

chmod 775 <DIRECTORY>
