# Chapter 4. Upgrading Cacti

1. Backup the old Cacti database.

       shell> mysqldump cacti > mysql.cacti

2. Backup the old Cacti directory.

       shell> mv cacti cacti_old

3. Extract the distribution tarball.

       shell> tar xzvf cacti-version.tar.gz

4. Rename the new Cacti directory to match the old one.

       shell> mv cacti-version cacti

5. Edit `include/config.php` and specify the MySQL user, password and database for your Cacti configuration.

       $database_default = "cacti";
       $database_hostname = "localhost";
       $database_username = "cactiuser";
       $database_password = "cacti";

6. Copy the *.rrd files from the old cacti directory.

       shell> cp cacti_old/rra/* cacti/rra/

7. Set the appropriate permissions on Cacti's directories for graph/log generation. You should execute these commands from inside Cacti's directory to change the permissions.

       shell> chown -R cactiuser rra/ log/

   (Enter a valid username for cactiuser, this user will also be used in the next step for data gathering.)

8. Point your web browser to:

   > http://your-server/cacti/

   Follow the on-screen instructions so your database can be updated to the new version.
