How to sync data between 2 servers automatically ?

Have you ever wanted to know how to easily synchronize the data between
multiple servers automatically?

In this article I’ll explain how to setup 2 Linux servers to automatically
synchronize data between a specific directory on each server. To do this
we will use rsync, ssh key authentication, and a cron job.

Let’s call the 2 servers ‘SOURCESERVER’ and ‘DESTSERVER’ for
SOURCESERVER = Source server (the server we’re connecting from to upload
the data)
DESTSERVER = Destination server (the server we’re connecting to receive
the data)


Part 1 - Setting up SSH key authentication

First, we need to make sure the DESTSERVER has the ability to use key
authentication enabled. Find your sshd configuration file (usually
‘/etc/ssh/sshd_config’) and enable the following options if they are not
already set.

RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys

If you edit the file be sure to restart sshd afterwards.

# /etc/init.d/sshd restart

Next, on the SOURCESERVER we will create the public / private key pair to
be used for authentication with the following command.

# ssh-keygen -t rsa

*Note: Do not enter a passphrase for this, just hit enter when prompted.

This should create 2 files, a public key file and a private key file.
The public key file (usually [homedir]/.ssh/id_rsa.pub) we will upload to
the DESTSERVER.
The private key file (usually [homedir]/.ssh/id_rsa) we will keep on the
SOURCESERVER.
*Be sure to keep this private key safe. With it anyone will be able to
connect to the DESTSERVER that contains the public key.

Now we will plant the public key we created on to the DESTSERVER.
Choose the user account which you will use to connect to on DESTSERVER,
we’ll call this user ‘destuser’ for now.
In that account’s home directory, create a ‘.ssh’ subdirectory, and in
that directory create a new text file called ‘authorized_keys’. If it
already exists, great, use the existing file.
Open the ‘authorized_keys’ file and paste in the contents of the public
key you created in the previous step (id_rsa.pub). It should look
something like the following

ssh-rsa  sourceuser@SOURCESERVER

Save the file and change the permissions to 600 for the file and 700 for
the ‘.ssh’ directory.

Now to test that the keys are working.
From the SOURCESERVER try logging in as normal using ssh to the DESTSERVER.

# ssh destuser@DESTSERVER

If all is working you should not be prompted for a password but instead
connected directly to a shell on the DESTSERVER.


Part 2 - Creating the rsync script

Now for the rsync script.
I use a simple script such as the following

——————————————-

#!/bin/bash

SOURCEPATH=’/source/directory’
DESTPATH=’/destination’
DESTHOST=’123.123.123.123′
DESTUSER=’destuser’
LOGFILE=’rsync.log’

echo $’\n\n’ >> $LOGFILE

rsync -avz -u --progress --delete $SOURCEPATH
$DESTUSER@$DESTHOST:$DESTPATH 2>&1 >> $LOGFILE
echo “Completed at: `/bin/date`” >> $LOGFILE

——————————————-

Copy this file into the home directory of the sourceuser on the SOURCESERVER
and modify the first 4 variables in the file.
SOURCEPATH (Source path to be synced)
DESTPATH (Destination path to be synced)
DESTHOST (Destination IP address or host name)
DESTUSER (User on the destination server)
Save it as something like ‘rsync.sh’
Set the permissions on the file to 700.
# chmod 700 rsync.sh

Now you should be able to run the script, have it connect to the
DESTSERVER, and transfer the files all without your interaction.
The script will send all output to the ‘rsync.log’ file specified in the
script.


Part 3 - Setting up the cron job

Assuming everything has worked so far all that’s left is to setup a cron
job to run the script automatically at a predefined interval.

As the same sourceuser use the ‘crontab’ command to create a new cron job.

# crontab -e

This will open an editor where you can schedule the job.
Enter the following to have the script run once every hour

——————————————-
# Run my rsync script once every hour
0 * * * * /path/to/rsync.sh
——————————————-

Your 2 servers should now be syncing the chosen directory once every hour.
Hope this helped, let me know if you have any questions.
