Question

我已经在Docker Container中设置了mongoDB Replicaset（3-repicas）。我可以从主机访问复制集，但无法从远程客户端访问mongoDB Replicaset。

参考：https://www.sohamkamani.com/blog/2016/06/30/docker-mongo-replica-set/

用于创建mongoDB副本集的脚本：

$ docker run -it -v <host mount path>:/data/db -p 30000:30000 --name mongo0 --net my-mongo-cluster -d mongo --replSet my-mongo-set --port 30000
$ docker run -it -v <host mount path>:/data/db -p 30001:30001 --name mongo1 --net my-mongo-cluster -d mongo --replSet my-mongo-set --port 30001
$ docker run -it -v <host mount path>:/data/db -p 30002:30002 --name mongo2 --net my-mongo-cluster -d mongo --replSet my-mongo-set --port 30002

$docker exec -it mongo1 mongo

以上命令成功。

我尝试从docker容器外部的同一主机访问mongo Replicaset：

> rs.initiate({_id: "my-mongo-set", version: 1, members: [
  { _id: 0, host : "mongo0:30000" },
  { _id: 1, host : "mongo1:30001" },
  { _id: 2, host : "mongo2:30002" }
]});

即使这样可行：

$ mongo mongodb://<PUBLIC_IP>:30000,<PUBLIC_IP>:30001,<PUBLIC_IP>:30002/?replicaSet=my-mongo-set
my-mongo-set:PRIMARY>

我的/ etc / hosts文件：

$ mongo mongodb://localhost:30000,localhost:30001,localhost:30002/?replicaSet=my-mongo-set
my-mongo-set:PRIMARY>

什么不起作用：从远程客户端（shell和MongoDB Compass）：

$ cat /etc/hosts
127.0.0.1 localhost mongo0 mongo1 mongo2
<PUBLIC_IP> <domain> mongo0 mongo1 mongo2

如何解决此问题？

Answer 1

这是因为从3.6版开始，mongod仅侦听localhost -address，直到您另行通知为止。检查here!或Google“ mongod bindIp”。
