[[SocketException错误，代码：48，当允许MongoDB进行远程连接时]

Question

我有一个运行Ubuntu的AWS ligthsail服务器。我刚刚安装了MongoDB，它在本地运行良好。现在，我想使用端口27017将其打开到远程位置。我已经将该端口添加到AWS控制台上的Networking列表中，并将我的公共IP添加到了配置文件中。

这是我运行mongo的命令：

sudo mongod --fork --config /etc/mongod.conf

这是我遇到的错误：

2020-04-07T11:40:24.424+0000 I CONTROL  [initandlisten] allocator: tcmalloc
2020-04-07T11:40:24.424+0000 I CONTROL  [initandlisten] modules: none
2020-04-07T11:40:24.424+0000 I CONTROL  [initandlisten] build environment:

2020-04-07T11:40:24.424+0000 I CONTROL  [initandlisten] options: { config:     "/etc/mongod.conf", net: { bindIp: "0.0.0.0,my-remote-ip", port: 27017 }, processManagement: {     fork: true, timeZoneInfo: "/usr/share/zoneinfo" }, storage: { dbPath: "the-path-to-the-db", journal: { enabled: true } }, systemLog: { destination: "file", logAppend: true, path: "/var/log/mongodb/mongod.log" } }
2020-04-07T11:40:24.424+0000 E STORAGE  [initandlisten] Failed to set up listener:     SocketException: Cannot assign requested address

2020-04-07T11:40:24.425+0000 I CONTROL  [initandlisten] shutting down with code:48

这是mongod的配置：

storage:
  dbPath: the-path-to-the-db
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0,<my-public-ip>


# how the process runs
processManagement:
  timeZoneInfo: /usr/share/zoneinfo

而且，我已经检查了正在运行的进程。 MongoDB未运行。我确定我也在SO和Google上搜索，但找不到任何东西。有人可以带领我解决这个问题吗？谢谢！

Answer 1

确定。我加了

security:
  authorization: "enabled"

到配置文件，然后使用以下命令配置ipteables

 sudo iptables -A INPUT -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPT
 sudo iptables -A OUTPUT  -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPT

显然在AWS UI上打开端口还不够。
