Installing orcharhino Server

This guide describes how to install orcharhino Server in a connected environment. You can install orcharhino Server on Alma Linux 8, Oracle Linux 8, Red Hat Enterprise Linux 8, and Rocky Linux 8.

  • If you want to install orcharhino Server within your VMware vSphere environment, you can use the orcharhino OVA image to run orcharhino on Alma Linux 8. This uses an open virtual appliance image (OVA) to create the orcharhino host in your VMware vSphere and automatically start the installation process.

  • If you want to provision a host to install orcharhino Server on, ATIX AG provides Kickstart files for Alma Linux 8, Oracle Linux 8, and Rocky Linux 8. This works in virtually any scenario including bare-metal installations.

  • If you already have an existing host for orcharhino Server, start a manual installation.

orcharhino is available through a subscription model. Please contact us about getting access.

Start your orcharhino Server installation process by carefully reading all prerequisites and requirements. If you want to deploy hosts into networks other than the one your orcharhino Server is in, you also need an orcharhino Proxy installed in each target network.

Prerequisites and System Requirements

ATIX AG recommends installing orcharhino Server on a virtual server. This allows you to create snapshot for backups among other advantages. Optionally, you can install orcharhino Server on a bare-metal system.

Before you install orcharhino Server, ensure that your environment meets the following requirements:

  • A host as outlined in the system requirements.

  • A network infrastructure as outlined in the network requirements.

  • An orcharhino Subscription Key used to register your orcharhino Server with ATIX AG.

    If you have an orcharhino subscription, you will receive your orcharhino Subscription Key and the required download links in your initial welcome email. If you have not received your welcome email, please contact us.

  • A browser on a secondary device that is able to resolve a route to your orcharhino Server.

  • A working internet connection, either directly or by using an HTTP/HTTPS proxy.

ATIX AG does not support using third party repositories on your orcharhino Server or orcharhino Proxies. Resolving package conflicts or other issues due to third party or custom repositories is not part of your orcharhino support subscription. Please contact us if you have any questions.

System Requirements

The system must meet the following requirements, regardless of whether it is a virtual machine or a bare-metal server:

~ 40 GiB for each Enterprise Linux distribution

~ 80 GiB for each Debian or Ubuntu distribution

~ 500 GiB (or as appropriate) if you plan to maintain additional repositories or keep multiple versions of packages

orcharhino Server requires two hard drives; one is used for the root partition and the other one for the data repositories. This separation is essential for the creation of snapshots and backups. The Kickstart files provided by ATIX AG do not work with a single drive system.

The main directories on /var are:

  • /var/cache/pulp/

  • /var/lib/pulp/

  • /var/lib/pgsql/

While it is technically possible to use different partitions for those directories, ATIX AG does not recommend doing so as it will negatively affect the overall performance of your orcharhino.

Using symbolic links is not an option as they break orcharhino-installer and corrupt the SELinux context if introduced at a later stage.

Ensure that you allocate sufficient hard drive resources at the beginning. Running out of space for your data repositories during regular orcharhino usage leads to significant pain.

To create backups using orcharhino-maintain, which rely on LVM snapshots, ensure your LVM volume group where vg-data resides has more than 2 GiB free disk space available. The free disk space is used during the creation of the snapshot to store all changes that are made to the database.

OS Requirements

You can install orcharhino Server on Alma Linux 8, Oracle Linux 8, Red Hat Enterprise Linux 8, and Rocky Linux 8. Your orcharhino Subscription Key is specific to your chosen platform. After your orcharhino Server is registered with ATIX AG, it receives packages for orcharhino Server and for your respective platform directly from ATIX AG. ATIX AG updates the platform packages regularly.

The installation of orcharhino Server on Oracle Linux is only supported on the latest released Oracle Linux 8 minor version (8.Y). You can find the latest Oracle Linux 8.Y release on yum.oracle.com.

If you perform a manual orcharhino Server installation, you have to download the install_orcharhino.sh script and run it. For more information, see Installing orcharhino Server Using the install_orcharhino.sh Script.

Ensure that you have the necessary Oracle Linux or Red Hat Enterprise Linux subscription if you want to install orcharhino Server on Oracle Linux or Red Hat Enterprise Linux. Your orcharhino subscription does not include any Oracle Linux or Red Hat Enterprise Linux subscriptions. Please contact us if you need help obtaining the relevant subscriptions or have questions on how to use your existing subscriptions.

Network Requirements

orcharhino works best when it is allowed to manage the networks it deploys hosts to, which means that it acts as DHCP, DNS, and TFTP server for those networks. Allowing orcharhino to manage networks in this way is optional but should be considered when planning an orcharhino installation. Running two DHCP services in the same network causes networking issues. Please contact us if you have any questions.

In order for orcharhino to manage hosts in one or more networks, it needs to be able to communicate with those hosts, possibly using an orcharhino Proxy. As a result, you need to open a set of ports to operate orcharhino on your network if you intend to use the corresponding service. There are generally three system types that need to connect to each other: orcharhino Server, orcharhino Proxies, and managed hosts.

Ports and Firewalls Requirements

For the components of orcharhino architecture to communicate, ensure that the required network ports are open and free on the base operating system. You must also ensure that the required network ports are open on any network-based firewalls.

Use this information to configure any network-based firewalls. Note that some cloud solutions must be specifically configured to allow communications between machines because they isolate machines similarly to network-based firewalls. If you use an application-based firewall, ensure that the application-based firewall permits all applications that are listed in the tables and known to your firewall. If possible, disable the application checking and allow open port communication based on the protocol.

Integrated orcharhino Proxy

orcharhino Server has an integrated orcharhino Proxy and any host that is directly connected to orcharhino Server is a Client of orcharhino in the context of this section. This includes the base operating system on which orcharhino Proxy is running.

Clients of orcharhino Proxy

Hosts which are clients of orcharhino Proxies, other than orcharhino’s integrated orcharhino Proxy, do not need access to orcharhino Server.

Required ports can change based on your configuration.

The following tables indicate the destination port and the direction of network traffic:

orcharhino Proxy functionality

Any managed host that is directly connected to orcharhino Server is a client in this context because it is a client of the integrated orcharhino Proxy. This includes the base operating system on which a orcharhino Proxy is running.

A DHCP orcharhino Proxy performs ICMP ping or TCP echo connection attempts to hosts in subnets with DHCP IPAM set to find out if an IP address considered for use is free. This behavior can be turned off using orcharhino-installer --foreman-proxy-dhcp-ping-free-ip=false.

  14. Click ACTIONS > Power > Power On to start your new VM. This automatically starts the orcharhino installation in the console you opened in step 13.

    After your orcharhino appliance is successfully registered with ATIX AG, a link to the orcharhino Installer GUI is displayed in the console from step 13.

  15. Enter the link in your browser and continue with the orcharhino Installer GUI.

Kickstart Installation Steps

You can use the Kickstart files provided by ATIX AG to install Alma Linux 8, Oracle Linux 8, or Rocky Linux 8 on the host orcharhino will run on.

Procedure

  1. Either virtually mount your installation media or place its physical equivalent in the DVD tray for a bare-metal installation.

  2. Boot your system from the installation media. Immediately halt the boot process by pressing the tab key and append the following boot option:

    ks=http://example.com/path/to/kickstart_file.ks

  3. Press enter to start the automatic Kickstart installation. The installation process prompts you to press enter from time to time.

  4. After the Kickstart installation has successfully completed, run the install_orcharhino.sh script.

Installing orcharhino Server Using the install_orcharhino.sh Script

You can use install_orcharhino.sh to start the installation process. The script registers your orcharhino Server with ATIX AG and starts the orcharhino Installer GUI.

The Kickstart installation places the install_orcharhino.sh script in the /root/ directory on your orcharhino Server. Alternatively, download the script directly from ATIX AG.

If you have an orcharhino subscription, you will receive your orcharhino Subscription Key and the required download links in your initial welcome email. If you have not received your welcome email, please contact us.

The install_orcharhino.sh script supports multiple options and requires your orcharhino Subscription Key. Run ./install_orcharhino.sh --help for a full list of options and usage instructions.

Procedure

  1. Start the installation process:

    # /root/install_orcharhino.sh --name="orcharhino.example.com" My_orcharhino_Subscription_Key

    ATIX AG recommends using the --name option to provide your orcharhino Server with a FQDN at this point.

  2. Confirm your settings to register with ATIX AG as follows:

    install_orcharhino.sh: You are about to register to OCC using the following settings:
install_orcharhino.sh:   orcharhino Subscription Key: 'My_orcharhino_Subscription_Key'
install_orcharhino.sh:   orcharhino FQDN: 'orcharhino.example.com'
install_orcharhino.sh:   orcharhino IP address: 'My_orcharhino_Server_IP_Address'
install_orcharhino.sh: Proceed with these settings? [Yes/No]

    If you enter anything other than Yes, yes, Y, or y, the script exits without taking any further actions. You can always rerun the script with modified options. You can override the My_orcharhino_Server_IP_Address setting using the -i/--ip-addr=ADDR option. You can skip the above confirmation prompt using the -y/--yes option.

  3. Access the link to continue with the orcharhino Installer GUI:

    http://My_orcharhino_Server_IP_Address:8015/?token=4f27b9328cc0ead7d499c93f34ec9bda5d26e7b50c4420dc0a80dcc04adcf9dd

    The installation process takes time depending on your environment.

Unattended orcharhino Installation

You can install orcharhino Server without user interaction using --skip-gui. This requires a valid /etc/orcharhino-installer/answers.yaml file. This method is an advanced installation method.

Using Custom Certificates

  1. Set use_custom_certs to true in /etc/orcharhino-installer/answers.yaml.

  2. Place your custom_certs.ca, custom_certs.crt, and custom_certs.key into /etc/orcharhino-installer/.

orcharhino Installer GUI

Continue with the orcharhino Installer GUI to finish your orcharhino Server installation process.

Procedure

  1. On the Initial Configuration screen:

    Setting initial configuration in orcharhino Installer GUI

    • Click Choose file and upload (1) to upload an answers.yaml file to prefill the orcharhino Installer GUI.

    • Enter the initial Organization and Location context (2) for your orcharhino. You can add additional organizations and locations later.

      One way to distinguish between orcharhino administrators and regular users is to place your orcharhino Server and any attached orcharhino Proxies into a separate location and/or organization context.

      Alternatively, you can achieve a fine grained permissions concept using roles and filters.

      Creating an Organization or Location that contains white space or non ASCII characters has been known to cause bugs. Please choose a single word that does not include umlauts or special characters.

    • Select a Tuning profile (3) using the slider. The tuning profile ensures that your orcharhino makes best use of its available resources of your orcharhino host. The prefilled value is based on the resources of the host. For more information, see Tuning orcharhino.

    • Click Next (4) to continue.

  2. On the Basic Configuration screen:

    Setting basic configuration in orcharhino Installer GUI

    • Enter a valid email address that can be used to reach the orcharhino administrator into the Admin email field (1).

    • Enter the password for your orcharhino admin account (2).

    • Optional: You can use custom certificates on orcharhino.

      • Click Choose file to upload a custom CA certificate (.ca) file (3).

      • Click Choose file to upload a custom certificate (.crt) file (4).

      • Click Choose file to upload a custom key (.key) file (5).

    • Optional: Select Use advanced options (6) to provide advanced installer options. For example, you can use this to define an external database with orcharhino. ATIX AG considers this is an advanced feature. If you are unsure, leave the field empty or contact us.

    • Click Next (7) to continue.

  3. On the HTTP Proxy Configuration screen:

    Setting HTTP proxy configuration in orcharhino Installer GUI

    • If your organization uses an HTTP proxy, select Use HTTP Proxy (1). Enter your HTTP/HTTPS proxy configuration data in the fields provided (2-6).

      Ensure that your HTTPS proxy does not modify the used certificates.

    • Click Next (7) to continue.

  4. On the Networking Capabilities screen:

    Selecting network capabilities in orcharhino Installer GUI

    ATIX AG recommends allowing orcharhino to manage DHCP, DNS, and TFTP on the subnet it manages hosts. Follow all of the steps below for this setup. However, if there is a good reason, then deselect the corresponding services (1), (6), and/or (11) and disregard steps (2a), (2b), and/or (2c).

    • Configure orcharhino’s DHCP capability (1).

      1. For the DHCP interface field (2), select the interface to the network orcharhino deploys hosts to. ATIX AG refers to this network as the internal network hence forth.

        The orcharhino Installer GUI prefills the input fields (3), (4), and (5) with plausible values based on your DHCP interface selection. Ensure to double check these auto-generated values before you continue.

      2. In the DHCP gateway IP field (3), enter the gateway IP address that managed hosts use on the internal network. The auto-generated value is the default gateway on the selected interface.

      3. In the DHCP nameservers field (4), enter the IP address that managed hosts use to resolve DNS queries. If Manage DNS (6) is selected, this is the IP address of the orcharhino host on the internal interface.

      4. For the DHCP range field (5), enter the range of IP addresses that is available for managed hosts on the internal network. The installer calculates the largest free range within the IP network by excluding its own address and those of the gateway and name server. It does not verify if any other hosts already exist within this range.

    • Configure orcharhino’s DNS capability (6).

      1. For the DNS interface field (7), select the interface to the internal network which you used for the DHCP interface field (2).

        The orcharhino Installer GUI prefills the input fields (8) and (9) with plausible values based on your DNS interface selection and the systems resolv.conf file. Ensure to double check these auto-generated values before you continue.

      2. In the DNS forwarders field (8), enter the IP address of your DNS server. The installer pre-fills this field with a DNS server from the system’s resolv.conf file.

      3. In the DNS reverse field (9), enter the net ID part of the IP address of the internal network in decimal notation, with the byte groups in reverse order, followed by .in-addr-arpa. For example, a network address of 192.168.0.0/24 would turn into 0.168.192.in-addr-arpa; pre-filled with the appropriate value for the chosen interface.

      4. In the DNS TTL (Time to Live) in sec field (10), enter a value in seconds.

    • Click Manage TFTP (11) to allow orcharhino Server to manage TFTP within its network.
