Original cacti host IP:222.65.193.176 standby cacti host IP:222.65.194.8

1. Back up the mysql and rrd data on the original cacti monitoring host

Backup database: mysqldump-p cacti > cacti.sql

Cacti, prompt to enter the cacti login password, enter, and the backed up data is under / root

2, backup rra files, du Niang said that backup rra files need to be backed up with rrdtool dump commands, I use tar packaging here.

# tar-cvf rra.tar / var/www/html/rra backed up 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 backup cacti

5. Restore rrd files

# tar xvf rra.tar unzipped files are available in / root (this is my current working directory)

# mv-f var/www/html/rra / root/var/www/html/rra

6. Restore database data: delete the cacti database in mysql first

# mysql-p enter the default mysql password

Mysql > drop database cacti delete cacti database

Mysql > create database cacti create a new cacti database

Mysql > ctrl+c

# mysql-p cacti
