Thank you for all your help,I installed opcua node successful.

The reason I can't success to install node is lack of dns server.

I use a DHCP server,but set static ip addess in interfaces,and the content of file /etc/resolv.conf is blank.

I add nameserver in that file,and successed to install all nodes.
