Learn how to – How To Install Xen Orchestra on Ubuntu / Debian

Learn how to – How To Install Xen Orchestra on Ubuntu / Debian.

Xen Orchestra (XO) is a web interface tool for Xen and XCP-ng Administrators to visualize and administer the complete Virtualization stack. The Xen Orchestra doesn’t require an agent installed on the Desktop machine for it work. All operations are performed from a web interface.

On the VM that hosts Xen Orchestra below are the minimal hardware requirements:

  • 2 vCPUs
  • 2GiB of RAM
  • 20GiB of free SR space (2GiB on thin pro SR)

The installation can be done on an instance running in XCP-ng or any other virtualization environment provided connectivity to Xen/XCP-ng servers is available.

To use a ready appliance refer to Deploying Xen Orchestra Appliance on Xen/XCP-ng from CLI

Step 1: Update System

Let’s start the installation by updating all the system packages:

sudo apt update

Also consider performing an upgrade:

sudo apt upgrade -y

With the upgrade done you can reboot now or at later stage.

Step 2: Install Node.js on Ubuntu | Debian

The next step is the installation of Node.js on Ubuntu / Debian Linux system:

curl -sL https://deb.nodesource.com/setup_16.x | sudo bash -

Once the repository is added proceed to install Node.js:

sudo apt install -y nodejs

To install the Yarn package manager, run:

curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | gpg --dearmor | sudo tee /usr/share/keyrings/yarnkey.gpg >/dev/null
echo "deb [signed-by=/usr/share/keyrings/yarnkey.gpg] https://dl.yarnpkg.com/debian stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update && sudo apt-get install yarn -y

Confirm installation of Node.js and Yarn

$ node -v
v16.20.0

$ yarn -v
1.22.19

Step 3: Install XO packages on Ubuntu 20.04|Debian 10

Install Python:

#For Python 3
sudo apt install python3-minimal

#For Python 2
sudo apt install python2-minimal

Install XO packages on Ubuntu 20.04|Debian 10 by running the commands below:

sudo apt update
sudo apt install build-essential redis-server libpng-dev git libvhdi-utils lvm2 cifs-utils

Confirm package installations:

The following NEW packages will be installed:
  binutils binutils-common binutils-x86-64-linux-gnu build-essential cifs-utils cpp cpp-9 dpkg-dev fakeroot g++ g++-9 gcc gcc-9 gcc-9-base
  libalgorithm-diff-perl libalgorithm-diff-xs-perl libalgorithm-merge-perl libasan5 libatomic1 libbfio1 libbinutils libc-dev-bin libc6-dev libcc1-0 libcrypt-dev

Step 4: Fetch Xen Orchestra Code and Build it

Next is to clone Xen Orchestra code from github:

git clone -b master https://github.com/vatesfr/xen-orchestra

Now that you have the code, you can enter the xen-orchestra directory

cd xen-orchestra

The start building of Xen Orchestra and install other dependency packages on Ubuntu / Debian system.

$ yarn
yarn install v1.22.19
[1/5] Validating package.json...
[2/5] Resolving packages...
[3/5] Fetching packages...
[4/5] Linking dependencies...
[5/5] Building fresh packages...

$ yarn build
yarn run v1.22.19
$ turbo run build --scope xo-server --scope xo-server-'*' --scope xo-web
• Packages in scope: xo-server, xo-server-audit, xo-server-auth-github, xo-server-auth-google, xo-server-auth-ldap, xo-server-auth-oidc, xo-server-auth-saml, xo-server-backup-reports, xo-server-load-balancer, xo-server-netbox, xo-server-perf-alert, xo-server-sdn-controller, xo-server-test, xo-server-test-plugin, xo-server-transport-email, xo-server-transport-icinga2, xo-server-transport-nagios, xo-server-transport-slack, xo-server-transport-xmpp, xo-server-usage-report, xo-server-web-hooks, xo-web
• Running build in 22 packages
• Remote caching disabled

 Tasks:    26 successful, 26 total
Cached:    0 cached, 26 total
  Time:    2m28.707s

Done in 149.37s.

Now you have to create a config file for xo-server:

cd packages/xo-server
sudo mkdir /etc/xo-server
sudo cp sample.config.toml /etc/xo-server/config.toml

In this config file, you can change default ports (80 and 443) for xo-server. If you are running the server as a non-root user, you will need to set the port to 1024 or higher.

You can try to start xo-server to see if it works. You should have something like this:

$ sudo yarn start
yarn run v1.22.19

 

You can now open your browser and visit xo-server IP address, and it works!

Configuring forever service

Use forever-service to install XO as a system service:

$ sudo yarn global add forever
yarn global v1.22.19
[1/4] Resolving packages...
[2/4] Fetching packages...
[3/4] Linking dependencies...
[4/4] Building fresh packages...

success Installed "forever@4.0.3" with binaries:
      - forever
Done in 6.06s.

$ sudo yarn global add forever-service
yarn global v1.22.19
[1/4] Resolving packages...
[2/4] Fetching packages...
[3/4] Linking dependencies...
[4/4] Building fresh packages...

success Installed "forever-service@0.5.11" with binaries:
      - forever-service
      - get-forever-config
Done in 4.28s.

$ cd ~/xen-orchestra/packages/xo-server/
$ sudo forever-service install orchestra -r root -s dist/cli.mjs
forever-service version 0.5.11

Commands to interact with service orchestra
Start   - "sudo service orchestra start"

Status  - "sudo service orchestra status"
Restart - "sudo service orchestra restart"

Let’s start the service:

sudo systemctl start orchestra

Also enable the service to start automatically after system boot.

$ sudo systemctl enable orchestra
orchestra.service is not a native service, redirecting to systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable orchestra

Confirm the service is running:

$ sudo ss -tunelp | grep *:80
tcp    LISTEN  0       511                        *:80                  *:*      users:(("node",pid=269785,fd=18)) ino:1883628 sk:9 v6only:0 <->

If you ever need to delete the service, run the command forever-service delete orchestra

Additionally install xo-cli tool.

$ sudo npm install --global xo-cli
