Chapter 4. Upgrading Cacti

1. Backup the old Cacti database.

shell

>

mysqldump  l   add drop table cacti

>

mysql.cacti

Note: You will probably have to specify the  u and  p flags for the MySQL username and password. This user

must have permission to read from Cacti's database or you will end up with an empty backup.

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. Copy any custom scripts from the old Cacti directory.

shell

>

cp cacti_old/scripts/* cacti/scripts/

8. Set the appropriate permissions on Cacti's directories for graph/log generation. You should execute these com 

mands 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.)

9. Point your web browser to:

http://your server/cacti/

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