我在osx笔记本电脑和远程ubuntu服务器上本地安装了mongodb。两者都运行着mongodb,我可以使用端口28017上的http诊断来验证这一点。我在两台计算机上运行相同的代码。在osx上一切都很好,但在Ubuntu上我无法通过NodeJS连接到数据库。我一直收到这样的错误:
Error: failed to connect to [localhost:27017]]
message: listen EADDRNOTAVAIL
stack: Error: listen EADDRNOTAVAIL
at errnoException (net.js:769:11)
at Server._listen2 (net.js:892:19)
at listen (net.js:936:10)
at Server.listen (net.js:993:9)
at asyncCallback (dns.js:67:16)
at Object.onanswer [as oncomplete] (dns.js:120:9)
我不明白的是,我可以通过mongo命令行接口在Ubuntu上进行本地连接。我还可以通过OSX计算机上的mongo命令连接到Ubuntu上的数据库。因此,MongoDB本身的安装似乎没有什么问题。
有人能想到我不能通过NodeJS连接的原因吗?我已经尝试过使用mongodb和mongoose包。两者都给了我相同的错误。
以下是我尝试过的两种方法:
var mongo = require("mongodb");
var host = "localhost";
var port = mongo.Connection.DEFAULT_PORT;
var db = new mongo.Db('node-mongo-examples', new mongo.Server(host, port, {}), {});
db.open(function(err, db){
if(err){
log.error('MongoDB connection error:', err);
}else{
log.info("OPEN MONGO CONNECTION");
}
});
和猫鼬:
var mongoose = require('mongoose');
var db = mongoose.createConnection('localhost', 'node-mongo-examples');
db.on('error', function(err){
log.error('MongoDB connection error:', err);
});
db.once('open', function () {
log.debug("OPEN MONGO CONNECTION");
});
在日志中,我没有看到任何特别的东西,也没有发生任何事情

我没有什么可试的了。有什么解决问题的建议吗?
