ethereum - How to synchronize the Raspberry PI with the private blockchain?

Question

I wanna create the private ethereum chain by geth, and I've started the node successfully and created the accounts on both raspberry.

and when I wanna synchronize both of it by admin.addPeer("enode..."), there seems to be nothing wrong.

but when I checked the network by admin.peers, it shows there's no peers in this network.

I assured that the networkid and the genesis are the same, and I start each geth node by the following command:

pi1$ geth --rpc --rpcport 8545 --datadir  "/home/pi/ChainSkills/node2"  --port 30002 --rpcapi "db,eth,net,web3" --rpccorsdomain "*" --networkid 8787 --nodiscover console

pi2$ geth --rpc --rpcport 8545 --datadir  "/home/pi/ChainSkills/node3"  --port 30003 --rpcapi "db,eth,net,web3" --rpccorsdomain "*" --networkid 8787 --nodiscover console

is there anything wrong?
