昨天部署了位元現金開發網節點，今天做個萊特幣的開發網試試

一、LTC鏡像生成

• 1.下載基礎鏡像

docker pull buildpack-deps:jessie-curl

• 2.撰寫Dockerfile

# vim Dockerfile 

FROM buildpack-deps:jessie-curl
RUN wget -O litecoin.tar.gz https://download.litecoin.org/litecoin-0.18.1/linux/litecoin-0.18.1-x86_64-linux-gnu.tar.gz \
        && tar -xzvf litecoin.tar.gz \
        && cd litecoin-0.18.1/bin \
        && mv litecoin-cli litecoin-qt litecoin-tx litecoind litecoin-wallet /usr/local/bin \
        && apt-get update \
        && apt-get install net-tools \
        && cd / \
        && rm -Rfv *litecoin*
EXPOSE 9332 9333 19332 19335 19443  19444
WORKDIR /root/.litecoin
ENTRYPOINT ["litecoind"]

注：EXPOSE用來指定埠，使容器內的應用可以通過埠和外界互動，rpc遠程呼叫協議的埠：(9332, testnet:19332, regtest: 19443)；其他節點同步埠：(main: 9333, testnet: 19335,regtest: 19444)，

• 3.構建鏡像

docker build . -t ltc/litecoin:v0.18.1

• 4.查看鏡像

# docker images
REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
ltc/litecoin             v0.18.1             344a75a75559        20 seconds ago      245MB

注：以上為個人根據版本更新情況構建LTC鏡像，也可以使用官方的bsv鏡像:https://hub.docker.com/r/uphold/litecoin-core

二、LTC容器生成

• 1.創建ltc資料目錄

mkdir -p /opt/docker/ltc-regtest/data

• 2.啟動ltc開發網容器

docker run -itd --restart=unless-stopped -v /etc/localtime:/etc/localtime -v /etc/timezone:/etc/timezone --name ltc-regtest -v /opt/docker/ltc-regtest/data:/root/.litecoin/regtest -p 19443:19443 -p 19444:19444 ltc/litecoin:v0.18.1 -regtest=1 -server=1 -rpcuser=admin -rpcpassword=123456 -txindex=1 -paytxfee=0.00005 -rpcport=19443 -rpcallowip=0.0.0.0/0 -port=19444 -rpcbind=0.0.0.0:19443

引數解釋

默認啟動為主網，不同網路之間的區別在于創世區塊不同，如果部署測驗網，引數應為：-testnet=1，如果部署開發網，可以使用引數：-regtest=1：表示啟動的是 regtest 網路；或者-chain=regtest指定需要使用的網路，

-txindex=1： 表示對所有的交易進行索引；否則默認只對與錢包地址有關的交易索引（使 getrawtransaction rpc 可呼叫完整的事務索引）

-server=1：表示接受命令列和JSON-RPC命令

-paytxfee=0.00005：手續費率指定，此引數表示：0.00005 LTC/kB

-rpcuser=admin：JSON-RPC連接的用戶名

-rpcpassword=123456：JSON-RPC連接的密碼

-rpcport=19443：JSON-RPC連接的埠（默認default（main）: 9332, testnet:19332, regtest: 19443）

-rpcallowip=0.0.0.0/0：允許來自指定源的JSON-RPC連接，可指定單個IP或一個網段，此選項可以指定多次

-rpcbind=0.0.0.0:19443：系結到給定的地址來監聽JSON-RPC連接

-port=19444：p2p監聽連接的埠，用于區塊鏈節點間的通信（default（main）: 9333, testnet: 19335,regtest: 19444）

三、查看bsv服務是否部署成功

• 1.查看容器是否成功啟動

# docker ps
CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS              PORTS                                                                       NAMES
0a2a17a57d06        ltc/litecoin:0.18.1             "litecoind -regtest=…"   2 minutes ago       Up 2 minutes        9332-9333/tcp, 19332/tcp, 19335/tcp, 0.0.0.0:19443-19444->19443-19444/tcp   ltc-regtest

• 2.查看服務啟動日志是否正常

# tail -f debug.log

四、常用介面使用

原來也寫過BCH鏈的rpc常用介面的使用方法，可進行參考：LTC （萊特幣）常用介面使用

• 創建地址 getnewaddress

# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnewaddress", "params": ["test2"] }' -H 'content-type: text/plain;' http://127.0.0.1:19443
{"result":"QYa78xSfwmwbK7r8fqDfXuPNei3qAdkMyG","error":null,"id":"curltest"}

• 出塊 generatetoaddress

注：LTC節點101塊時產生出塊收益

# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "generatetoaddress", "params": [6,"QYa78xSfwmwbK7r8fqDfXuPNei3qAdkMyG"] }' -H 'content-type: text/plain;' http://127.0.0.1:19443
{"result":["40e2560bbb2f6734b689d3ee787a0e384670110f5f1f7649ee8908a2dc735cc3","54bc2c3a61e41beebd5557e75fc27da01431d1104e4cb3df8f8343ad6a863dab","ab0aed03ed82f2f1af05a27ee6a45a414318020822b6e7ab9d6eacc56c2ae902","23a7a63f1e7ca48d2ee6a0b51245aab0b6da702c4e7535b55cc88d9a58302da5","c51ca0837c4a172716c2a3e491df3cf4aaa50369f92b467f062515052621a945","1cc7b5cb64000934d9a4705cf0922ca2c847c3f51bfa80ad459298fbd50f1861"],"error":null,"id":"curltest"}

• 獲取最新區塊高度 getblockcount

# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockcount", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:19443
{"result":101,"error":null,"id":"curltest"}

• 顯示bch錢包中所有地址余額 listaddressgroupings

# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "listaddressgroupings", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:19443
{"result":[[["QYa78xSfwmwbK7r8fqDfXuPNei3qAdkMyG",50.00000000,"test2"]]],"error":null,"id":"curltest"}

• 發送金額至指定地址 sendtoaddress

# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "sendtoaddress", "params": ["Qg3o1dH1NhG47rYboni3ZxwLsGnSNn7eyY",11] }' -H 'content-type: text/plain;' http://127.0.0.1:19443
{"result":"d674d7bbc1bb7c7562b34f2cb66263dfbf84abe5e6bdafc1aabf7b393e671ed9","error":null,"id":"curltest"}

• 查詢未花費輸出 listunspent

# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "listunspent", "params": [1, 9999999, ["QYa78xSfwmwbK7r8fqDfXuPNei3qAdkMyG"]] }' -H 'content-type: text/plain;' http://127.0.0.1:19443
{"result":[{"txid":"c38e8746213d1946149aca1d9dc0dc33bcefd86955f2ca1533047da4a8ba9eb4","vout":0,"address":"QYa78xSfwmwbK7r8fqDfXuPNei3qAdkMyG","label":"test2","redeemScript":"0014589e7111fafe6d92225fc39273fc01a4acbc4ebb","scriptPubKey":"a91483468b6e080369225ec72c92e51a5bbfbd913be487","amount":50.00000000,"confirmations":102,"spendable":true,"solvable":true,"desc":"sh(wpkh([bb2327d0/0'/0'/0']037208c027b4e4945b01360d738572608f1ee269de3cc02f94bc886fcebdbaaa51))#q6avw075","safe":true},{"txid":"aaae37410a1f4c4cfb456606bb7fab7e42383f0d42fb5b9e1ad047cedafa5cd7","vout":0,"address":"QYa78xSfwmwbK7r8fqDfXuPNei3qAdkMyG","label":"test2","redeemScript":"0014589e7111fafe6d92225fc39273fc01a4acbc4ebb","scriptPubKey":"a91483468b6e080369225ec72c92e51a5bbfbd913be487","amount":50.00000000,"confirmations":101,"spendable":true,"solvable":true,"desc":"sh(wpkh([bb2327d0/0'/0'/0']037208c027b4e4945b01360d738572608f1ee269de3cc02f94bc886fcebdbaaa51))#q6avw075","safe":true}],"error":null,"id":"curltest"}

以上，就是今天分享的全部內容了，
