Writable directory needed...

Before you can install Habari, you first need to make the install directory writable by php, so that the installation script can write your configuration information properly. The exact process depends on the web server and the ownership of the directory.

If your web server is part of the group which owns the directory, you'll need to add group write permissions to the directory. The procedure for this is as follows:

  1. Open a terminal window, and then change to the installation directory: 
    $> cd /path/to/habari/
  2. Change the mode (permissions) of the current directory: 
    $> chmod g+w .

    $> chmod g+x .

    Note: You may need to use sudo and enter an administrator password if you do not own the directory.

If the web server is not part of the group which owns the directory, you will need to temporarily grant world write permissions to the directory: 

  1. $> chmod o+w .

    $> chmod o+x .

Be sure to remove the write permissions on the directory as soon as the installation is completed.
