For Nodes #2-8 here's what I recommend. Ignore the posts after reboot.
Open a new putty window then run these commands without parentheses. Replace XXX.XXX.X.XX with your manager's IP. For example my Manager IP is 192.168.1.75 and Nodes 2-8 are 76-82. Only run the second command (nohup....) once or the node will constantly reset in the manager. This will allow you to close the session without losing connection to the node in Manager. Happy mining!
"cd $GOPATH/bin"
"nohup ./node -connect-manager -manager-address XXX.XXX.X.XX:5998 -manager-web XXX.XXX.X.XX:8000 > /dev/null 2>&1 & echo $! > node.pid"
nohup ./node -connect-manager -manager-address MANAGER_IP:5998 -manager-web MANAGER_IP:8000 -discovery-address discovery.skycoin.net:5999-034b1cd4ebad163e457fb805b3ba43779958bba49f2c5e1e8b062482904bacdb68 -address :5000 -web-port :6001 > /dev/null 2>&1 &
That is the new discovery address.
