Here's the details on installing Urbackup on the ZFS file system on the stable CentOS 7.
- Install CentOS 7. I'll be using the Minimal install.
- Once you have the .iso, write it to a CD or USB drive. I recommend using Rufus if you're on Windows to write it to USB.
- Go ahead and boot to it.
- Most of the defaults on the Installation Summary page should be good. However you will want to:
- Confirm the time zone is correct.
- Click the disk you want to install to.
- Enable the network and set a hostname.
- On the next page, set a root password and make a user account.
- Check the box to make the user administrator.
- After it's finished installing, reboot and log in as the user you created.
- (Side note, you may want to ssh into your machine now to make copy and pasting commands easier.)
- First thing you'll want to do is get your system up to date with
sudo yum update - Install some other programs with
sudo yum install vim wget - Install ZFS using the guide here. I'll list the commands below as well.
- Download the package:
sudo yum localinstall http://download.zfsonlinux.org/epel/zfs-release$(rpm -E %dist).noarch.rpm - Add zfsonlinux's gpg key with
gpg --quiet --with-fingerprint /etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux - Modify the repo file with
sudo vim /etc/yum.repos.d/zfs.reposo that zfs-kmod is the only repository enabled. The guide mentioned above might make it more clear. - Install ZFS with
sudo yum install zfs - Enable the ZFS kernel module with
sudo modprobe zfs - Now we can create a pool of disks.
- Check which disks are available with
lsblk. The disk with your OS on it will probably be sda, with the other disks being sdb, sdc, or the like. - I just have one disk right now, so I'm going to create a pool named ocean with the command
sudo zpool create ocean sdb -f- The
-fflag is to force an overwrite of data. It is very important to double-check that sdb is referring to the actual disk you want to erase.
- The
- I am also going to enable compression with
sudo zfs set compression=lz4 ocean - By default, your pool will now be mounted at /ocean.
- Now we can install Urbackup.
- Set up uroni's repo.
- Change directories into the repo listings with
cd /etc/yum.repos.d/ - Download the repo config file with
sudo wget http://download.opensuse.org/repositories/home:uroni/CentOS_7/home:uroni.repo
- Change directories into the repo listings with
- Install Urbackup with
sudo yum install urbackup-server - Start Urbackup with
sudo systemctl start urbackup-server - Enable it to start on boot with
sudo systemctl enable urbackup-server - Make a subdirectory for Urbackup to store its files in with
sudo mkdir /ocean/urbackup - Give ownership to the urbackup user with
sudo chown urbackup:urbackup /ocean/urbackup - Now we can configure Urbackup.
- Go to the web config page at http://hostname:55414.
- Under Settings, you'll want to change the backup storage path to /ocean/urbackup.
That completes the server setup! You'll want to install the clients on each of the machines now.
