使用docker运行status节点

配置要求

• 内存>=1GB
• CPU>=1核
• 硬盘空间
  如果开启-mailserver选项，文档中描述的是一个月大约消耗600MB的空间；如果不开启-mailserver选项则无此消耗，节点将仅用作Whisper消息服务器
• 操作系统
  只要可以运行docker理论上应该都可以，注：此文以linux系统为例

关于如何安装docker，此处略过，具体步骤可参见docker官网

运行节点

1. 创建http-enabled.json文件
   echo '{ "HTTPEnabled": true, "HTTPHost": "0.0.0.0", "APIModules": "admin,debug" }' > http-enabled.json
2. 拉取并启动status节点docker镜像

    docker run \
    -p 8545:8545 \
    -p 30303:30303 \
    -v $(pwd)/http-enabled.json:/config/config.json \
    statusteam/status-go \
    -register \
    -mailserver \
    -log DEBUG \
    -c /config/config.json

校验节点是否运行正常

执行如下命令：

curl -X POST \
    -H "Content-Type: application/json" \
    -d '{"jsonrpc":"2.0","method":"admin_peers","params":[],"id":1}' \
    localhost:8545

，正常的话你将看到类似如下响应：

{"jsonrpc":"2.0","id":1,"result":[{"enode":"enode://a80eb084f6bf3f98bf6a492fd6ba3db636986b17643695f67f543115d93d69920fb72e349e0c617a01544764f09375bb85f452b9c750a892d01d0e627d9c251e@47.89.16.125:30305?discport=0","id":"36f613e54cb8412a1830fffd5c0b4099b1b9c107d6ab7104a27367b29fd5178b","name":"Statusd/vdeploy-staging/linux-amd64/go1.10.8","caps":["shh/6"],"network":{"localAddress":"172.17.0.2:56732","remoteAddress":"47.89.16.125:30305","inbound":false,"trusted":false,"static":true},"protocols":{"shh":"unknown"}},{"enode":"enode://960777f01b7dcda7c58319e3aded317a127f686631b1702a7168ad408b8f8b7616272d805ddfab7a5a6bc4bd07ae92c03e23b4b8cd4bf858d0f74d563ec76c9f@47.52.58.213:30305","id":"781b904d6468f2c996ed15d4a16a7b7d248e995b03e6b98bdd4fb62a444ec8a0","name":"Statusd/vdeploy-staging/linux-amd64/go1.10.8","caps":["shh/6"],"network":{"localAddress":"172.17.0.2:41148","remoteAddress":"47.52.58.213:30305","inbound":false,"trusted":false,"static":true},"protocols":{"shh":"unknown"}},{"enode":"enode://7c80e37f324bbc767d890e6381854ef9985d33940285413311e8b5927bf47702afa40cd5d34be9aa6183ac467009b9545e24b0d0bc54ef2b773547bb8c274192@47.91.155.62:30305?discport=0","id":"84d828cecc6d7fa6e4f831501e528f8593999d9972d4e5b46a22defb5fe554b2","name":"Statusd/vdeploy-staging/linux-amd64/go1.10.8","caps":["shh/6"],"network":{"localAddress":"172.17.0.2:39454","remoteAddress":"47.91.155.62:30305","inbound":false,"trusted":false,"static":true},"protocols":{"shh":"unknown"}}]}

-mailserver选项

打开-mailserver开关默认会加载如下配置：

{
    "WhisperConfig": {
        "Enabled": true,
        "EnableNTPSync": true,
        "EnableMailServer": true,
        "MailServerPassword": "status-offline-inbox"
    }
}

其中的MailServerPassword正如其命名，是邮件服务器的密码，在后面会用到。

status手机端app添加自定义邮件服务器

以ios版本为例，邮件服务器的设置菜单路径：
个人资料-->高级-->邮件服务器，点击右上角的加号+进行添加，名称自己随便定，其中邮件服务器地址格式模板为：enode://{enode-id}:{password}@{ip-address}:{port}，这个地址在节点启动的时候会在日志中输出，例如其日志内容类似如下：

INFO [02-15|09:20:35.006] UDP listener up                          net=enode://d848d1f3c12b07419860d7f9409c601c334ae6d9283f6395e050dc3a7a00e7e12d06d4fc54d1d47a407a92723cdab5d963959908a4922ff6e9f30118bc79b2a0@[::]:30303

日志内容太多，可搜索关键字UDP listener up。
假设节点机器的ip为47.244.23.30，则对应的实际邮件地址我们应该填写为：enode://d848d1f3c12b07419860d7f9409c601c334ae6d9283f6395e050dc3a7a00e7e12d06d4fc54d1d47a407a92723cdab5d963959908a4922ff6e9f30118bc79b2a0:status-offline-inbox@47.244.23.30:30303
注意：在选择使用自定义的邮件服务器后，app可能会要求你重新输入密码登录

使用自建节点的好处

• 连接更稳定；app默认提供的列表节点可能在国外，我这边的使用情况是经常提示Error connect to mail server...
• 接收消息速度加快
• 去中心化
