I often useCactiTo prevent data loss, we need to perform Cacti data at any time.BackupAnd migration!

I. Workflow

Copy the cactid directory tarball to the new monitoring server in the dual-line data center for decompression;

Copy the mysql database dump or tarball to the new monitoring server in the dual-Data Center for decompression;

 
 

  
  
#mysqldump -p cacti >cacti.sql  
  
  
 
 
 

Re-grant cactiuser all permissions for the database cacti;

 
 

  
  
grant all . cacti.* to cactiuser@localhost identified by 'cactipassword';

When cacti is enabled, you can log on and control it normally. Check graph management and open all the diagrams without displaying them. Then, enable debug mode:

 
 

  
  
*Turn . Graph Debug Mode.
