I run Graylog on Hyper V, but there is no network connection, there is message about “failed to connect to lvmetad”
If you use OVA, this VM by default support obtaining IP address from DHCP.
So first check your network interface loging into ubuntu using username: ubuntu and password: ubuntu.
After that check your interface name and ip adress using command: sudo ip addr show
If you don’t have DHCP in your network, you have to configure IP address manualy using netplat like this:
sudo vim /etc/netplan/01-netcfg.yaml
network:
version: 2
renderer: networkd
ethernets:
ens160:
addresses:
- 10.0.0.10/24
gateway4: 10.0.0.1
nameservers:
addresses: [10.0.0.1]
Change line ens160: to your real interface name (output of command: sudo ip addr show)
sudo netplat apply
Graylog show default web interface password for admin user only first time on console (it’s generated). So if you restart your VM second time, you can’t see it. If so you have 2 options:
- Either generate your own password and setup it to parameter
root_password_sha2
sudo vim /etc/graylog/server/server.conf
https://docs.graylog.org/en/3.1/pages/configuration/server.conf.html#general - Or remove generated password on parameter
root_password_sha2so line like will look like this:root_password_sha2 =. After that create file /var/lib/graylog-server using command:sudo touch /var/lib/graylog-server/firstbootand reboot. After reboot you should see new password on console before login.
sudo vim /etc/graylog/server/server.conf
sudo touch /var/lib/graylog-server/firstboot
sudo reboot
Can you tell me how to save the file after editing, i edited the file in ova but how do i exit and save. In terminal.
To save file in vim editor, simply press: Esc and type :wq and press Enter
and what shortcut for editing
Please use this indentation… so either add space to desired lines, or replace with next block
network:
version: 2
renderer: networkd
ethernets:
enp0s10f0:
addresses:
- 192.168.40.62/24
gateway4: 192.168.40.1
nameservers:
addresses: [192.168.40.1]
