Scuttle is a free open source software for creating social bookmarking sites like del.icio.us. You can create a social bookmarking site in minutes using scuttle for your personal or for community use. Scuttle code is available from sourceforge.net.
Scuttle supports most of the del.icio.us API, so you can modify the del.icio.us tools to work with scuttle.
Import your existing bookmarks from browsers or from del.icio.us.
Scuttle is Ajaxified. It generates RSS feeds.
Download the files from sourceforge.net project page and upload it to your server where you want to install scuttle.
Rename the config.inc.php.example file to config.inc.php and fill the database information. Enter host as localhost (most of the cases), no need to change port, username and password and upload it to your server. You would also want to change the name of the site, go down in config.inc.php file you will find sitename tag (line 88) there enter your sitename by replacing scuttle.
Create a database in the server and load the tables.sql file, this can be done through phpmyadmin.
Once database is setup point your borwser to your site, now it should show you the scuttle bookmark site.
Register now as a user and start using it to store your bookmarks. Scuttle doesn’t creat any admin users because there is nothing much for admin to do in the site. If you prefer not to allow users to register in your site, you can delete the register.php page. If you ever wanted to add users you can add them to the database. I will explain that below.
How to add users from phpMyAdmin:
Enter phpmyadmin and select your scuttle database. Select sc_users table from the database, click on insert tab in phpmyadmin
now enter user details like uId (userid), username and password. Password should be md5 hashed for security. See the below snapshots on how to do md5 hashing.
After md5 hashing passwords look like this
Thats all, now your social bookmarking site is ready, enjoy
