-
-Before starting the installation and deployment of O-RAN INF, you need to download the ISO image or build from source as described in developer-guide.
-
-
-Hardware Requirements
----------------------
-
-Following minimum hardware requirements must be met for installation of O-RAN INF image:
-
-+--------------------+----------------------------------------------------+
-| **HW Aspect** | **Requirement** |
-| | |
-+--------------------+----------------------------------------------------+
-| **# of servers** | 1 |
-+--------------------+----------------------------------------------------+
-| **CPU** | 2 |
-| | |
-+--------------------+----------------------------------------------------+
-| **RAM** | 4G |
-| | |
-+--------------------+----------------------------------------------------+
-| **Disk** | 20G |

-Software Installation and Deployment
-------------------------------------
-
-1. Installation from the O-RAN INF ISO image
-````````````````````````````````````````````
-
-- Please see the README.md file for how to build the image.
-- The Image is a live ISO image with CLI installer: oran-image-inf-host-intel-x86-64.iso
-
-1.1 Burn the image to the USB device
-''''''''''''''''''''''''''''''''''''
-
-- Assume the the usb device is /dev/sdX here
-
-::
-
- $ sudo dd if=/path/to/oran-image-inf-host-intel-x86-64.iso of=/dev/sdX bs=1M
-
-1.2 Insert the USB device in the target to be booted.
-'''''''''''''''''''''''''''''''''''''''''''''''''''''
-
-1.3 Reboot the target from the USB device.
-''''''''''''''''''''''''''''''''''''''''''
-
-1.4 Select "Graphics console install" or "Serial console install" and press ENTER
-'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
-
-1.5 Select the hard disk and press ENTER
-''''''''''''''''''''''''''''''''''''''''
-
-Notes: In this installer, you can only select which hard disk to install, the whole disk will be used and partitioned automatically.
-
-- e.g. insert "sda" and press ENTER
-
-1.6 Remove the USB device and press ENTER to reboot
-'''''''''''''''''''''''''''''''''''''''''''''''''''
-
-2. Configuration for better real time performance
-`````````````````````````````````````````````````
-
-Notes: Some of the tuning options are machine specific or depend on use cases,
-like the hugepages, isolcpus, rcu_nocbs, kthread_cpus, irqaffinity, nohz_full and
-so on, please do not just copy and past.
-
-- Edit the grub.cfg with the following example tuning options
-
-::
-
- # Notes: the grub.cfg file path is different for legacy and UEFI mode
- # For legacy mode: /boot/grub/grub.cfg
- # For UEFI mode: /boot/EFI/BOOT/grub.cfg
-
- grub_cfg="/boot/grub/grub.cfg"
- #grub_cfg="/boot/EFI/BOOT/grub.cfg"
-
- # In this example, 1-16 cores are isolated for real time processes
- root@intel-x86-64:~# rt_tuning="crashkernel=auto biosdevname=0 iommu=pt usbcore.autosuspend=-1 nmi_watchdog=0 softlockup_panic=0 intel_iommu=on cgroup_enable=memory skew_tick=1 hugepagesz=1G hugepages=4 default_hugepagesz=1G isolcpus=1-16 rcu_nocbs=1-16 kthread_cpus=0 irqaffinity=0 nohz=on nohz_full=1-16 intel_idle.max_cstate=0 processor.max_cstate=1 intel_pstate=disable nosoftlockup idle=poll mce=ignore_ce"
-
- # optional to add the console setting
- root@intel-x86-64:~# console="console=ttyS0,115200"
-
- root@intel-x86-64:~# sed -i "/linux / s/$/ $console $rt_tuning/" $grub_cfg
-
-
-- Reboot the target
-
-::
-
- root@intel-x86-64:~# reboot
-
-3. Kubernetes cluster and plugins deployment instructions (All-in-one)
-``````````````````````````````````````````````````````````````````````
-This instruction will show you how to deploy kubernetes cluster and plugins in an all-in-one example scenario after the above installation.
-
-3.1 Change the hostname (Optional)
-''''''''''''''''''''''''''''''''''
-
-::
-
- # Assuming the hostname is oran-aio, ip address is <aio_host_ip>
- # please DO NOT copy and paste, use your actaul hostname and ip address
- root@intel-x86-64:~# echo oran-aio > /etc/hostname
- root@intel-x86-64:~# export AIO_HOST_IP="<aio_host_ip>"
- root@intel-x86-64:~# echo "$AIO_HOST_IP oran-aio" >> /etc/hosts
-
-3.2 Disable swap for Kubernetes
-'''''''''''''''''''''''''''''''
-
-::
-
- root@intel-x86-64:~# sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
- root@intel-x86-64:~# systemctl mask dev-sda4.swap
-
-3.3 Set the proxy for docker (Optional)
-'''''''''''''''''''''''''''''''''''''''
-
-- If you are under a firewall, you may need to set the proxy for docker to pull images
-
-::
-
- root@intel-x86-64:~# HTTP_PROXY="http://<your_proxy_server_ip>:<port>"
- root@intel-x86-64:~# mkdir /etc/systemd/system/docker.service.d/
- root@intel-x86-64:~# cat << EOF > /etc/systemd/system/docker.service.d/http-proxy.conf
- [Service]
- Environment="HTTP_PROXY=$HTTP_PROXY" "NO_PROXY=localhost,127.0.0.1,localaddress,.localdomain.com,$AIO_HOST_IP,10.244.0.0/16"
- EOF
-
-3.4 Reboot the target
