Install and upgrade issues on virtual machines

Occasionally, you might encounter issues during installation and upgrade of YugabyteDB Anywhere on a virtual machine. Most of these issues are related to connections.

If you experience difficulties while troubleshooting, contact Yugabyte Support.

Docker Engine connection to host issues

If your YugabyteDB Anywhere host has a firewall managed by firewalld enabled, then Docker Engine might not be able to connect to the host. To resolve the issue, you can open the ports using firewall exceptions by using the following commands:

sudo firewall-cmd --zone=trusted --add-interface=docker0
sudo firewall-cmd --zone=public --add-port=80/tcp
sudo firewall-cmd --zone=public --add-port=443/tcp
sudo firewall-cmd --zone=public --add-port=8800/tcp
sudo firewall-cmd --zone=public --add-port=5432/tcp
sudo firewall-cmd --zone=public --add-port=9000/tcp
sudo firewall-cmd --zone=public --add-port=9090/tcp
sudo firewall-cmd --zone=public --add-port=32769/tcp
sudo firewall-cmd --zone=public --add-port=32770/tcp
sudo firewall-cmd --zone=public --add-port=9880/tcp
sudo firewall-cmd --zone=public --add-port=9874-9879/tcp

Node access issues

The node access might not be available due to IP addresses that cannot be resolved. To remedy the situation, you can create mount paths on the nodes with private IP addresses 10.1.13.150, 10.1.13.151, and 10.1.13.152 by executing the following command:

for IP in 10.1.12.103 10.1.12.104 10.1.12.105;
do
  ssh $IP mkdir -p /mnt/data0;
done

Node connection issues

If a firewall is enabled for nodes, it might interfere with node connections. To resolve the issue, you can add firewall exceptions on the nodes with private IP addresses 10.1.13.150, 10.1.13.151, and 10.1.13.152 by executing the following command:

for IP in 10.1.12.103 10.1.12.104 10.1.12.105;
do
  ssh $IP firewall-cmd --zone=public --add-port=7000/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=7100/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=9000/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=9100/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=11000/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=12000/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=9300/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=9042/tcp;
  ssh $IP firewall-cmd --zone=public --add-port=6379/tcp;
done
