addSealer: Set the corresponding node as the consensus node according to the node NodelD
addObserver: Set the corresponding node as an observation node according to the node NodelD
removeNode: Set the corresponding node as a free node according to the node NodelD getSealerList: View the list of consensus nodes in the group
getObserverList: View the list of observation nodes in the group
getNodelDList: View the NodelD of all other nodes to which the node is connected
Simple operation of calling HelloWorld contract
1. Deploy the contract (the contract has been placed in fisco/console/contracts/solidity/HelloWorld.sol)
deploy HelloWorld
Executing this command will return two values
2. Call the contract
call HelloWorld "transaction" get
call HelloWorld "contract address" set "Hi,word"
3. Quit the console quit
Commands related to expanding the capacity of new nodes
Generate node private key certificate
bash gen_node_cert.sh -c ../cert/agency -o node4Confirm that node4 establishes a connection with other nodes
tail -f node4/log/log* | grep "connected count"Node joins group
1. Get the nodeid of the node
cat node4/conf/node.nodeid2. Use the console to add node4 as an observation node to group 1
addObserver "nodeid"
Then execute getObserverList and you will find that the id appears
3. Use the console to join node4 as a consensus node in group 1
addSealer "nodeid"
Then execute getOSealerList and you will find that the id appears
Additional instructions about nodes
Convert the specified node to a free node
removeNode + "the nodeid"
Query node list
getNodeidList

$ curl -X POST --data '{"jsonrpc":"2.0","method":"getPeers","params":[1],"id":1}'
http://127.0.0.1:8545 |jq
In this command, 8545 is the rpc port number of the node.
