# ethereum(Docker) ## 安裝: 這邊我們會使用`Docker`，並使用ethereum相關的container來進行\ 所以須先安裝好`Docker`\ 並且執行 再來開啟terminal 1.加入以太坊的public network ``` docker run -d --name ethereum-PublicNode \ -v $HOME/.ethereum:/root \ -p 8545:8545 -p 30303:30303 \ ethereum/client-go --fast --cache=512 ``` 執行attach ``` docker exec -ti ethereum-PublicNode geth attach ``` 2.加入以太坊的test network ``` docker run -d --name ethereum-TestNode \ -v $HOME/.ethereum:/root \ -p 8544:8544 -p 30304:30304 \ ethereum/client-go --testnet --fast --cache=512 ``` 執行attach ``` docker exec -ti ethereum-TestNode \ geth attach ipc:/root/.ethereum/testnet/geth.ipc ``` 查看LOG ``` docker logs ethereum-Testnode ``` > attach的意思是在terminal啟動一個javascript的相關以太坊API執行環境\ > 但我們這邊主要教學部分為Private chain\ 使用 ``` git clone https://github.com/vertigobr/ethereum.git cd ethereum ``` 我們可以到他的repo中點選`Dockerfile` 看到 ``` ENV GEN_NONCE="0xeddeadbabeeddead" \ NET_ID=1981 ``` 這兩個分別是創世區塊的識別ID與private network的識別ID，所以未來加入其他節點這兩個都要與其他節點的值相同才會加入，預設我們不用去改他 我們也可以用`-e`來指定執行docker時的環境變數 ``` docker run .... -e GEN_NONCE='stag0x2222ing' ``` 講解其中的一些.sh程式 ``` bootnode.sh: 執行Ethereum bootnode 啟動節點; runnode.sh: 執行Ethereum 非挖礦節點; runminer.sh: 執行Ethereum 挖礦節點; showpeers.sh: 顯示所有連線到此節點的節點 killall.sh: 將會執行"docker stop" 與 "docker rm" ; wipeall.sh: 將會執行"docker stop" 與 "docker rm" 並且清空 volume folders. ``` 進入到資料夾後使用 ### 1.啟動起始節點 ``` ./bootnode.sh ``` 使用`docker logs ethereum-bootnode`查看log 查看剛才的boot節點 ``` ./getbootnodeurl.sh ``` 查看log ``` docker logs ethereum-bootnode ``` ### 2.再來啟動另一個非mining的節點 ``` ./runnode.sh node1 ``` 查看logs ``` docker logs ethereum-node1 ``` 這時發現這個node沒找到任何其他節點，只出現以下，像bootnode不停查詢是否有其他節點，所以他覺得滿孤單 ``` dial tcp 172.17.0.2:30301 與 seed node ``` ### 3.新增第二個非mining的節點 ``` ./runnode.sh node2 ``` 這時我們回去察看node1的log，可看到類似如下 ``` Peer e4a6e56cf9096420 [eth/63]: peer connected [Geth/v1.4.11-stable/linux/go1.5.1/node2] ``` 這時2與1兩節點就發現彼此了 ### 4.查看節點所連結的節點 (bootnode)不包含在內 ``` ./showpeers.sh ethereum-node1 ``` ### 5.啟動一個mining節點(挖礦節點) ``` ./runminer.sh miner1 ``` 查看logs ``` docker logs ethereum-miner1 ``` 挖礦前他會花一些時間準備，所以一開始只會看到如下 ``` I0208 08:18:46.744549 ethash.go:291] Generating DAG: 33% I0208 08:18:53.107984 ethash.go:291] Generating DAG: 34% ``` 等到他跑到100%，準備完成後他會開始挖礦，可看如下logs ``` I0208 08:26:48.411384 miner/worker.go:435] 🔨 🔗 Mined 5 blocks back: block #3 I0208 08:26:48.411470 core/database_util.go:353] stored block receipts [989a7a59…] ``` 這時可再次查看剛才node1的logs `docker logs ethereum-node1` ``` I0208 08:27:35.038805 core/database_util.go:303] stored block body [2f9292d4…] I0208 08:27:35.039183 core/database_util.go:288] stored header #22 [2f9292d4…] I0208 08:27:35.040653 core/blockchain.go:931] [1486542455040638728] inserted block #22 (0 TXs 0 G 0 UNCs) (2f9292d4...).
