mongodb - replSet 的 Mongo DB 问题

Question

我正在尝试这个:

mongod --replSet mySet --dbpath /data/r1 --port 27017 --oplogSize 700

mongod --replSet mySet --dbpath /data/r2 --port 27018 --oplogSize 700

mongod --replSet mySet --dbpath /data/r3 --port 27019 --oplogSize 700

然后在新终端中:

/mongo --port 27017
MongoDB shell version: 2.0.2
connecting to: 127.0.0.1:27017/test 

> cfg = {

    _id : "mySet",
    members : [
    { _id : 0, host : "localhost:27017" },
    { _id : 1, host : "localhost:27018" },
    { _id : 2, host : "localhost:27019" } ] } 

当我运行时

rs.initiate(cfg)

我收到这个错误:

{ "errmsg" : "server is not running with --replSet", "ok" : 0 }

为什么会出现此错误？

我试过本教程 replSet但仍然没有

Answer 1

我能想到的一个原因是，在尝试启动 mongod 之前，您已经在端口 27017 上运行了一个没有 --replSet 参数的 mongod。在尝试此操作之前，请确保没有 mongod 正在运行(ps aux |grep mongod)。我还会检查日志文件，因为它可能提供了为什么它没有以副本集模式启动的线索。
