製作私有鏈

運營私有網絡

到目前為止，atlas 既有 POC 版本，也有 POS 版本。下面分別介紹如何在兩個不同的版本上搭建四個節點的私網。

##先決條件

私鑰和地址
構建圖集需要 git、Go（1.14 或更高版本）和 C 編譯器。您可以使用您喜歡的包管理器安裝它們。
克隆存儲庫

git clone https://github.com/mapprotocol/atlas.git
cd atlas

構建四個節點

我們可以在一台主機上啟動四個不同端口的節點，也可以在多台主機上啟動四個節點。下面將使用在一台主機上啟動四個不同端口的node方法來進行演示。

-構建POC版本圖集：

git checkout v0.2
make atlas

構建POS版本atlas：

git checkout v1.0.0 or git checkout <latest tag>
make atlas

創建四個驗證者賬戶

私鑰和地址
Atlas 允許開發者在 atlas 區塊鏈上使用以太坊的賬戶。如果沒有帳戶，使用命令會有所幫助。```shell $ ./atlas --datadir ./node-1 account new $ ./atlas --datadir ./node-2 account new $ ./atlas --datadir ./node-3 account new $ ./atlas --datadir ./node-4 account new

輸出

您可以與任何人分享您的公共地址。其他人需要它與您互動。
您絕不能與任何人共享密鑰！鑰匙控制著您的資金使用權！
您必須備份您的密鑰文件！沒有密鑰，就無法訪問帳戶資金！
你必須記住你的密碼！沒有密碼，就無法解密密鑰！


## 生成一個 genesis.json
**注意版本之間是有區別的，POC版本不需要設置validator。
僅適用於 POS 版本。 必須設置驗證器，因為只有他們才可以挖礦。**

獲取驗證器配置 json 並生成一個 genesis.json
- [生成 genesis.json ](./how-to-make-genesis.md#generating-a-genesis.json-file)

我們現在使用上一步生成的四個帳戶的路徑生成 genesis.json 文件。
將我們創建賬戶時輸出的信息填入對應的鍵值中。
`AdminAddress`鍵對應的值可以是我們上面創建的四個賬戶中的任意一個，也可以是其他賬戶。

就像下面這樣：

```json

啟動四個驗證節點

下面的命令使用之前創建的四個賬戶啟動對應的四個節點。

./atlas --datadir ./node-1 --networkid 110112 --port 20201 --mine --miner.validator 0xF930B74D2b1b703B879ab54E225ECc18Ab28e61C --unlock 0xF930B74D2b1b703B879ab54E225ECc18Ab28e61C console

在命令行中輸入以上命令並回車，會看到如下提示：

這個時候我們需要輸入賬號對應的密碼回車，恭喜，您已經成功啟動了一個節點。然後我們以相同的方式啟動剩餘的節點。

如果你想啟動一個 RPC 節點你可以使用下面的方式。

./atlas --datadir ./node-rpc init ./genesis.json

./atlas --datadir ./node-rpc --networkid 110112 --port 20205 --http --http.addr "0.0.0.0" --http.port 7445 --http.api eth,web3,net,debug,txpool,header,istanbul --http.corsdomain "*" console

連接四個節點

標誌的操作。

bootnode 可操作且外部可訪問（嘗試 telnet <ip> <port> 以確保它確實可以訪問），啟動每個後續的 atlas 節點通過“--bootnodes”標誌指向用於對等發現的引導節點。它會可能還需要將您的專用網絡的數據目錄分開，所以還要指定一個自定義的 --datadir 標誌。

$ atlas --datadir=path/to/custom/data/folder --bootnodes=<bootnode-url>

the Operation on a console.

查詢自己的node-url：

admin.nodeInfo.enode
"enode://6a469a852c7ee7f656e33a7858db5c480d6253ad760771a779985c305d66de78109bae579adf3f32fbd770e44145d5728176bcddda56d8a8c92709f827d94842@127.0.0.1
:20201"

連接驗證節點，例如：

admin.addPeer("enode://8f8bb96b01be9f76a93b2b54bcaff35b48ace58f0b0f3c85a139048072ff030bcad022a442e49181885f1f0338a5efd2f4807d21d2f88973e18426dee3d8e0b7@127.0.0.1:20201")
admin.addPeer("enode://a4642d6eb2f1c69ee861f4146636df028a7eb328e233f620cc6838db474e94327bdcdc810d2f9c2fa30694764e71b4c7b5828f6e8df7a3f71f3eb781bb017a4e@127.0.0.1:20202")

查看節點狀態

您將開始看到一些輸出。幾分鐘後，您應該會看到如下所示的線條。這意味著您的節點已連接其他節點並開始生產塊。
