In addition, there are SELinux permissions, which are a whole other discussion and not within the scope of this article. You need to think about that when setting up firewall rules and permissions. Both of these can be problematic in a secure environment, so tread carefully here.Īlso, note that by default, when you use rsync remotely, you are connecting directly to the rsync service on port 873.

Another way is to run rsync as a user with the required permissions. For one, it's possible to specify the uid and gid of the rsync daemon in /etc/nf.

There are several ways you can accomplish this. Rsync needs permission to the whole directory tree, not just the destination directory. This is a good time to note that there are some things you need to think about when using rsync to push files. Rsync: recv_generator: mkdir '/usr/share/httpd/enable/enable' failed: Permission denied (13) So let’s say I wanted to add a page to the site and upload it: skipworthy ~ enable websync rsync -aruv. Note: -v almost always means verbose, sending output to the console.

You can use rsync to synchronize any remote filesystem for backups or as a quick way to create a test-to-production pipeline. I could keep a local copy to work on and also have a backup of the latest version of the site. I first started using rsync to synchronize a local version of a website I administered back in the dark ages when CI/CD was just a twinkle in her father's eye. Rsync can provide encryption to protect it in transit, compression to make it flow better, and checksums to ensure you get what you were expecting. Sometimes, however, you may want to do something a little more sophisticated, like move data across a less trusted or slower link. Copying files to and from remote systems and having an easy way to run a backup of something you're working on (or, for that matter, critical company data) are basic, useful tools in the sysadmin toolbox that I use again and again. There are also a couple of other great articles here on Enable Sysadmin on tar and SSH you should take a look at. In a previous article entitled Sysadmin tools: Using rsync to manage backup, restore, and file synchronization, I discussed cp and sftp, and looked at the basics of rsync for moving files around.
