Cacti Backup and Migration

Original cacti host ip:222.65.193.176 standby cacti host ip:222.65.194.8

1. Backup the MySQL and RRD data on the original cacti monitor host

Backup database: Mysqldump-p cacti >cacti.sql

Cacti, prompt input cacti login password, enter, backup good data under/root

2, Backup Rra file, Degree Niang said backup Rra file needs to be backed up with RRDtool dump command, I am here to use tar packaging.

#tar-CVF Rra.tar/var/www/html/rra Backup good data under/root

3. Copy the Cacti.sql and Rra.tar files to the new cacti server.

#scp Cacti.sql 222.65.193.8:/root

#scp Rra.tar 222.65.193.8:/var/www/html

4. Enter the standby cacti

5. Restore the RRD file

#tar xvf Rra.tar extracted files in/root (this is my current working directory)

#mv-F Var/www/html/rra/root/var/www/html/rra

6. Recover database data: First delete the cacti database in MySQL

#mysql-P Enter the default MySQL password

Mysql>drop database cacti Delete cacti databases

Mysql>create database cacti Create a new cacti

Mysql>ctrl+c

#mysql-P cacti <cacti.sql prompt input cacti login password, enter, restore database

7. Restart the mysqld and httpd services and force image generation

# Service Mysqld Restart
# Service httpd Restart
#/usr/bin/php/var/www/html/poller.php--force

8, open the website sometimes prompts the database error, click: Check can open cacti. Note that the password to login here is the original cacti password.

PS above method cannot restore the weather map, wait for Swaiiow to study again.
