How to install lsyncd
What is lsyncd?
The lsyncd tool monitors specified directories (including subdirectories) for updates and modifications and then syncs those changes to a specified destination. Using the Lua programming language, it is an easy-to-install and easy-to-configure lightweight command application.
Install lsyncd
As a first step, we will ensure that the list of available packages on the server is up to date before installing anything new.
Ubuntu
apt-get -y update && apt-get upgrade -yCentOS
yum update -yOur next step will be to install lsyncd and any required packages.
Ubuntu
apt-get -y install lsyncdCentOS
yum install lsyncd -yThis is how you can restart & enable lsyncd.
systemctl start lsyncd
systemctl enable lsyncdYou can now verify your installation.
lsyncd --versionConfiguration
Now we will create a new lsyncd config file with our information stored in it. We will use this file to define the sources and destinations of the sync.
vim /etc/lsyncd/lsyncd.conf.luaAn example configuration to sync 2 local folders would look like this.
settings {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/log/lsyncd/lsyncd.status",
statusInterval = 30,
nodaemon = false
}
sync {
default.rsync,
source = "/home/quickhostuk/public_html",
target = "/backup/quickhostuk/public_html"
}An example configuration to sync local to remote folders would look like this.
settings {
logfile = "/var/log/lsyncd/lsyncd.log",
statusFile = "/var/log/lsyncd/lsyncd.status",
statusInterval = 30,
nodaemon = false
}
sync {
default.rsyncssh,
source = "/home/quickhostuk/public_html",
targetdir = "/backup/quickhostuk/public_html",
host = "192.168.1.2",
delay = 5,
rsync = { rsh="/usr/bin/ssh -l sshuser -i /home/sshuser/.ssh/id_rsa -o StrictHostKeyChecking=no"}
}Once this is complete, you are finished with the setup process and can now begin synchronizing your files from your source directory to your target directory.
