Airwave Root

Leave a reply

AirWave 8.2.10.0 CentOS7 install:

Re-Enable Root, Reset Password, and delete GRUB

Yes, you need to boot from a Live Distro, or mount the disk with another VM. Knppoix/Ubuntu/Backtrack are what I typically have on hand. If you use Ubuntu make sure you use

“Try without Installing” / Try Ubuntu and don’t install over your AMP server

– Shutdown the AirWave VM

– Add CD ROM to VM, and mount ISO to CD ROM.

– Edit VM Options, Boot Options, Force BIOS setup

              You may have Boot from EFI option with 6.7U3

– Save 

– Boot the AirWave VM

– In the vm BIOS got right to the Boot option

– Hightlight the CD-ROM option, and ++ to move it above Hard Drive

– Exit, Save Changes, Yes

– If Ubuntu use “Try Ubuntu” Option

– open terminal:

 Remove Grub Password

You probably don’t need this but here if you need to get into the boot loader:

sudo mount /dev/sda2 /mnt

sudo nano /mnt/grub/grub.conf

– delete the line that starts with password

– save file

umount /mnt

Enable Root Login

While you’re here go ahead and re-enable root login.

Mount the / drive:

sudo mount /dev/mapper/vg_system-lv_root /mnt

Change passwd file:

sudo nano /mnt/etc/passwd

change the root from nologon to /bin/bash

root:x:0:0:bin:/bin:/sbin/nologin  to  root:x:0:0:root:/root:/bin/bash

Set/Reset Root/Console Password

– set the root password / reset the ampadmin password

cd /mnt

sudo chroot /mnt

passwd ampadmin

passwd root

exit

Unmount the drive and reboot

cd /

sudo umount /mnt

Reboot Ubuntu/Linux and edit the VM setting to disconnect the CDROM and boot into AirWave. 

Airwave Upgrade for New Centos

Leave a reply

Basic Crib

the OVA file contains the new version if used to build a new instance.  A hardware AW upgrade would be similar in process, but we would have to build it from scratch (install the OS first, then use the .iso file for the AW install) on the same box after copying off the backup file.

To upgrade CentOS for Airwave the process in the Release Notes is correct:

  1. First, upgrade your live AW to 8.2.10.0.  This upgrades the databases so they can be restored later in the steps.
  2. Backup this live AW and copy off this backup file somewhere
    1. (CLI) Backup > Backup Now. 
      1. (GUI) To grab the “nightly” or “weekly” backups – if you’ve waited long enough since the upgrade to 8.2.10.0 so they can run since your upgrade – go to System > Backups
    2. Command line for SCP from AW (don’t use Solarwinds SFTP/SCP Server as it doesn’t like the encryption ciphers… OpenSSH in Linux works well) (This step is the most difficult in terms of getting the SCP server running, reachable, and the syntax correct):
      1. If I had a “awbackupfolder” folder on my Linux box on the Desktop for a user named “username”, I would reference the existing folder as relatively from my login directory: Desktop/awbackupfolder/  (the trailing “/” is optional here)
      2. The CLI SCP syntax cannot take the “~” tilde character so reference the folder in another way
      3. username@192.168.21.21:Desktop/awbackupfolder/
    3. Power off the AW server (we’ll need the new box to have the same IP because AW licenses are tied to it)
  3. Build a new AW server with the right storage, cpu, and memory requirements.  This is a good opportunity to increase hard disk size if you’ve been holding off.
    1. Building from OVA file will install the CentOS 7 version.
    2. To login to the newly deployed box, use the default: user = root and password = admin
    3. Use the same basic startup-script info as before, keeping the same IPs
    4. You will need a complex password.  Store it somewhere safe: this is your CLI and your WebUI password for “admin” login
  4. Once the box is up, from the CLI copy over the backup file via SCP.
    1. Files > Upload
      1. username@192.168.21.21:Desktop/awbackupfolder/ampbackup_date_time.tar.gz
  5. Now restore from the backup.
    1. Backup > Restore > AMP Restore, select the file.  Sometimes the numbers don’t match what you type – I think due to hidden files (.digest files).  Make sure it is the right one (it should be the only one here)
    2. VisualRF backup file is already contained in the AW Backup file, so there isn’t a need to do that restore separately.
  6. Log in to the system after it is up with the new password.  Perform basic checks that information is still flowing correctly.
  7. Delete the old virtual machine once everything is running fine.
  8. Have a cup of coffee.

When setting up Aruba Mesh with instants do not forget to turn off extended SSID.

Steps

  1. Create cluster with IAP let them sync with image and configuration (update them to lateist code)
  2. Disable the extended SSID ( in the latest version 4.x, it is enabled) in options
  3. you will find both the IAPs as mesh portals.
  4. Remove the IAP from the Switch which you want to make mesh point and provide external power.
  5. After booting, there will be a mesh link between two IAPs.
