Instead, it starts automatically with your server at boot time, and runs silently in the background. You’ll need to be the “root” user to install packages! If you are using CentOS, Fedora, or Red Hat, you can use the yum package manager to install: Install Lsyncd on CentOS, Fedora, or Red Hat Imagine if you didn’t have to manually create backups of your website on your web server every time you made a small change? That could be a real time saver! Let’s dig in. When you configure lsycnd correctly, it can automatically synchronize folders between two computers. You usually don’t have to manually run daemons every time you want to use them, as they are typically configured to start automatically when your server boots. Sounds scary, but in computer terminology, daemons are merely applications that run as a background process. Unlike rsync, which has to be run manually, lsyncd is a daemon. The utility lsyncd is somewhat similar to rsync in that it is used to synchronize two folders. Transferring only the changed parts of a file can be a huge time saver, but especially when copying files remotely like in that last example.įinally, we’ll talk about lsyncd. If only the last few bits of a file has changed, rsync solely copies the changes, rather than the whole file. One of the great things about rsync is that it intelligently copies files. v = print verbose messages to screen, (very helpful!) a = archive mode (includes several commonly used options: -rlptgoD, check the rsync man page for detailed info.) We used some special options in that last example. Once again, rsync is the tool for the job! Using SSH is fantastic from a security point of view, and it allows you to use SSH keys to avoid typing passwords.Īs one last example, let’s try copying something from your remote server “192.168.0.100” over to your local machine. One of the great things about rsync is that it performs remote transfers of data securely, through SSH. Rsync -avHl /path/of/source/folder how just as before, we specified our source first, and destination second. In this example, we’re going to use rsync to copy a directory from our local computer over to our web server “192.168.0.100”. Now that you have the basics let’s try another common task. When you run rsync, remember always to put the “source” first, and “destination” second!
