Explore more about Lsyncd CentOS

Lsyncd is abbreviated as “Live Syncing Daemon“.

It is a rsync and SSH-based tool. And it mainly monitors the changes to local files and directories, then syncs those changes to a specified destination.

We use this simple way to keep the local directory automatically synchronized with the servers.

 

How we install Lsyncd CentOS?

Let’s now go through the steps of how our Support Engineers install lsyncd in CentOS.

 

1. Install EPEL via yum

Initially, we install the EPEL repository using the command

yum install epel-release

 

2. Update the package

Then, we ensure that the packages are updated. So we run the below command to run an update if any packages are not updated.

yum -y update

 

3. Installing and configuring Lsyncd CentOS

Now, we install the lsyncd by running the command

yum -y install lsyncd

After installing it, we modify the configuration file from the path /etc/lsyncd.conf as below.

----
-- User configuration file for lsyncd.
--
-- Simple example for default rsync.
--
settings {
statusFile = "/tmp/lsyncd.stat",
statusInterval = 1,
}

sync {
default.rsync,
source="/var/www/html",
target="192.168.1.14:/var/www/html",
rsync={rsh ="/usr/bin/ssh -l root -i /root/.ssh/id_rsa",}
}

And then we enable and start the lsyncd through below commands:

systemctl enable lsyncd

systemctl start lsyncd

 

5. Checking the status

Finally, we check the lsyncd status Report as below.
