使用Docker安裝EOS
2020-06-16 16:44:26
前言
接上一篇通過eosio_build.sh指令碼安裝EOS，其實EOS官方更推薦我們使用Docker來安裝（EOS官方已經把編譯好的映象檔案上傳到Docker公共倉庫中），簡單快速，且不用趟編譯過程中的各種依賴坑，所以在此牆裂推薦一下。
一、安裝Docker
參見我的另一篇文章：在Ubuntu下安裝Docker https://www.linuxidc.com/Linux/2018-09/154498.htm
二、安裝EOS
通過Docker安裝EOS，安裝過程非常簡單，只需要從官方拉取一個image即可，安裝時間在10分鐘不等。
1、拉取EOS官方Docker image
$ docker pull eosio/eos-dev
Using default tag: latest
latest: Pulling from eosio/eos-dev
a48c500ed24e: Pulling fs layer
1e1de00ff7e1: Pulling fs layer

Status: Downloaded newer image for eosio/eos-dev:latest
2、啟動EOSIO節點
$ sudo docker run --rm --name eosio -d -p 8888:8888 -p 9876:9876 -v /tmp/work:/work -v /tmp/eosio/data:/mnt/dev/data -v /tmp/eosio/config:/mnt/dev/config eosio/eos-dev /bin/bash -c "nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::wallet_plugin --plugin eosio::producer_plugin --plugin eosio::history_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --config-dir /mnt/dev/config --http-server-address=0.0.0.0:8888 --access-control-allow-origin=* --contracts-console"
啟動正常情況下，返回一個容器ID：
2e1a3574dd2908645843152e5d561af53f3ffa777a99d6ecdd152f5a91230f6f
三、驗證節點通訊
1、檢查節點是否已經正常工作：
$ sudo docker logs --tail 10 eosio
正常情況下輸出的內容應該類似於這樣：

2、在瀏覽器中檢視節點資訊：
在瀏覽器位址列存取 http://localhost:8888/v1/chain/get_info，檢查RPC介面是否正常工作，正常情況下會顯示：
{
"server_version": "5875549c",
"chain_id": "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",
"head_block_num": 2233,
"last_irreversible_block_num": 2232,
"last_irreversible_block_id": "000008b872290cc75b8cb68b836a82ff87a1cc39b75f88341765f68bc925a623",
"head_block_id": "000008b9c9c9c11ee3e4c95613c971861788f7e80a82e20bcad0c2ef622aa7be",
"head_block_time": "2018-07-05T04:20:43.000",
"head_block_producer": "eosio",
"virtual_block_cpu_limit": 1861596,
"virtual_block_net_limit": 9777935,
"block_cpu_limit": 199900,
"block_net_limit": 1048576
}
以上資訊我們還可以通過cleos get info命令檢視到。
至此，我們就在Docker容器中成功地執行了一個EOS節點區塊鏈！
四、用戶端設定
1、在docker下使用cleos用戶端，我們需要以Docker的命令方式來執行，且需要帶命令的完整路徑
，如/opt/eosio/bin/cleos，為了後續操作方便，我們給cleos命令設定一下別名：
alias cleos='docker exec eosio /opt/eosio/bin/cleos --wallet-url http://localhost:8888'
我們試著在終端測試一下是否生效：
$ cleos --help
看到命令的相關引數資訊就說明已經可以執行生效了。
2、關閉節點執行
$ docker stop eosio
之前使用eosio_build.sh指令碼的安裝方式時，只能粗暴的按Ctrl+C中斷節點，有了Docker後，就能優雅地關閉節點了。
