Cause

• In order to use the Magento Connect Manager for installing, or upgrading, Magento software, you must has write permission s on all Magento files, including the main installation folder, or root folder.

"Recursively means entering each folder your find below the root folder and changing the permissions on all the files and Folders it contains and so on the file system hierarchy to the bottom of the directory tree.

File Permissions

• Under the Unix operating system, file permissions is divided into three groups: "User," "group" and "other." Within each group, individual file permissions is represented by the letters R, W and X--for "read," "Write" and "Execu TE "--or by the numbers 4, 2 and 1, in binary. The command "chmod 777 {filename}" Changes the permissions on {filename} to read, write and execute for everyone.

Adding Write Permissions

• You can change the file permissions via a file Transfer Protocol (FTP) or Secure Shell (SSH) client. FTP is a software protocol for exchanging information between computers over a network, while SSH was a shell program for E xecuting commands on a remote computer. To change file permissions via a SSH client, log in to your SSH account and type the following Unix commands:
  Cd
  Find. -type d-exec chmod 777 {} \;
  chmod 666 Downloader/config.ini

However, once you ' ve completed the installation or upgrade, you need to remove the Write permissions from the files and fo Lders once again. To does this via SSH, type the following commands:
