# Installation
|
|
|
|
## Minimal HW/VM Requirements
|
|
- 4GB RAM
|
|
- 33GB Disk
|
|
|
|
## Network Installation
|
|
|
|
The machine you want to install needs to be [registered in `sysdb`](../admin-guide/deployment/sample). If you don't have the bob command installed locally you can login to __lxsup.psi.ch__ to use it. Remember that you need a valid Kerberos ticket before modifying a sysdb entry via `bob`.
|
|
More details regaring `bob` can be found [here](https://git.psi.ch/linux-infra/bob).
|
|
|
|
Optional you can set `netboot` and RHEL 8 installer but that can also be selected manually in be boot menu:
|
|
|
|
```
|
|
bob node netboot $FQDN
|
|
bob node set-attr $FQDN ipxe_installer=rhel8install
|
|
```
|
|
|
|
|
|
|
|
### Installation with UEFI
|
|
Start the machine and select network boot (if not already the default), then you get following menu:
|
|
|
|
|
|
There select "Install Red Hat Enterprise Linux 8.7"
|
|
|
|
|
|
|
|
__NOTE:__ After the installation the boot order will be changed to localboot again! So if you reinstall make sure that you re-set the bootorder via the efi menu or the commandline: https://linux.die.net/man/8/efibootmgr
|
|
```
|
|
[root@lx-test-02 ~]# efibootmgr
|
|
BootCurrent: 0004
|
|
BootOrder: 0004,0002,0000,0001,0003
|
|
Boot0000* EFI Virtual disk (0.0)
|
|
Boot0001* EFI VMware Virtual SATA CDROM Drive (0.0)
|
|
Boot0002* EFI Network
|
|
Boot0003* EFI Internal Shell (Unsupported option)
|
|
Boot0004* Red Hat Enterprise Linux
|
|
|
|
[root@lx-test-02 ~]# efibootmgr --bootorder 2,4,0,1,3
|
|
```
|
|
(there is no need to have the leading 000 )
|
|
|
|
### Installation with Legacy BIOS
|
|
Start the machine and select network boot (if not already the default), then you get following menu, where the default depends on the `sysdb` configuration, but you may override it manualy:
