节点 ECONNRESET 隧道-ssh 和猫鼬

Question

当我启动 Express 时，它会在大约 5 分钟后崩溃。

使用此依赖项。

• 快递4.17.1
• 猫鼬 5.9.7
• 隧道-ssh 4.1.4

等待大约 5 分钟后，出现这样的错误。

[nodemon] starting `node bin/www`

      throw er; // Unhandled 'error' event
      ^

数据库连接。

module.exports.A = async () => {
  this.ssh = await tunnel({
    keepAlive: true,
    host: HOST,
    username: USERNAME,
    privateKey: fs.readFileSync(KEY),
    dstHost: DST_Host,
    dstPort: DST_Port
  })

  mongoose.connect(URL, {
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useCreateIndex: true
  })
}

module.exports.B = async () => {
  this.ssh.close()
}

SSH 配置。

Host *
  ClientAliveInterval 8
  ServerAliveInterval 60
  TCPKeepAlive yes

已解决

  mongoose.connect(URL, {
    useNewUrlParser: true,
    useUnifiedTopology: true,
    useCreateIndex: true,
    serverSelectionTimeoutMS: 30000, // Use this.
    socketTimeoutMS: 30000 // Use this.
  })
