without password
Login to Primary Server and check the IP address
Login to Secondary Server and check the IP address
From Primary Server create the SSH Key with
"ssh-keygen". Please do not provide any password to make it password
less.
Create .ssh directory in Secondary Server with below command.
# mkdir /root/.ssh/
Send the "id_rsa.pub" public key from Primary
Server to Secondary Server
# scp /root/.ssh/id_rsa.pub root@192.168.0.3:/root/.ssh
On Secondary Server create a file name
"authorized_keys" and put the content of "id_rsa.pub" on
that file
# touch /root/.ssh/authorized_keys
# cat /root/.ssh/id_rsa.pub >>
/root/.ssh/authorized_keys
Set permissions on Secondary Server
#chmod -R 700 /root/.ssh/
#chmod -R 640 /root/.ssh/authorized_keys
Now try to login from Primary Server to Secondary server
without password
# ssh 192.168.0.3
Install rsync in both server
On both server run following command to install rsync
# apt-get install rsync -y
Automate a directory to sync with
Secondary server
Let say I want to copy “/home/” directory from Primary
Server to Secondary server automatically every day at 1 AM.
Add the line below in /etc/crontab file
00 1 * * * root rsync -avzhe ssh /home/
192.168.0.3:/home/
Now restart cron Service
