Macos 无法连接到mongodb错误号：61连接被拒绝

我最近用安装了mongodb-2.6.0。 成功安装后，我尝试使用

mongo

命令进行连接。我收到以下不允许我连接的错误：

Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused

Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146

exception: connect failed

要解决您的问题，您需要遵循brew在使用“brew安装mongodb”后提供给您的说明

要在登录时启动mongodb，请执行以下操作：

ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

然后立即加载mongodb：

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist

或者，如果您不想/不需要launchctl，您可以运行：

mongod --config /usr/local/etc/mongod.conf

您可以只运行最后一个命令，但它对我不起作用，我需要运行第二个命令。为了将来救我。我也只是执行了第一个命令。希望有帮助

---

EDITHrishi使用

brew服务mongodb start

的方法对我很好。我认为他们应该在mongo文档中包含这一点。

当mongodb服务没有在mac上运行时，可能会发生这种情况。首先，我试着

brew services start mongodb

它成功了

brew服务

已被弃用，我查看了一下，发现这些答案现在回答了问题：

在另一个选项卡中，您可以使用

蒙哥德

然后返回上一选项卡并重试。如果您在设置mongoshell时遇到问题，请查看mongoshell上的以下链接： 或安装mongodb时的以下链接：

---

我犯了同样的错误，但根本原因不同。我想我会在这里发布解决方案，以防其他人遇到这个问题。我在运行

mongorestore-d foo dump/foo/

时，Mac电脑不正确地关闭后，出现了这个错误

tl；dr：我通过删除损坏的

foo.ns

文件以及

foo.0

，

foo.1

，。。。从我的数据文件夹

/usr/local/var/mongodb/

。然后，我使用

brew服务重新启动mongodb

重新启动mongo服务器，恢复正常

详细信息：即使尝试通过brew或launchctl启动或重新启动mongodb服务，我仍不断收到错误。最后我跑了

mongod--dbpath/usr/local/var/mongodb

并看到服务没有实际启动，启动顺序包含以下错误：

[initandlisten]坏的.ns文件：/usr/local/var/mongodb/foo.ns
[initandlisten]用户断言：10079:bad.ns文件长度，无法打开数据库

---

我去掉了坏的

.ns

文件和其余的数据文件，下次启动服务时，我就可以继续了。

从命令行调用

mongod

时，我也遇到了同样的问题

---

我通过调用sudo mongod解决了这个问题，我遇到了完全相同的问题，这里有一个清晰的逐步过程来避免这个错误

步骤1安装（如果您已经安装了MongoDB，请不要执行此步骤）：

步骤2-运行Mongo守护程序：

mkdir -p /data/db
sudo mongod

步骤3-运行Mongo Shell界面：

mongo

在这个序列中，我能够毫无错误地运行

mongo

命令。我还详细介绍了错误跟踪及其解决方案

我的猜测是，您在尝试通过“mongo”命令访问测试时没有运行的数据库

首先在终端中运行此命令：

然后打开另一个终端窗口并运行：

蒙戈

现在一切都应该正常了

---

对于osx上的我来说，我必须杀死旧的运行实例，然后重新启动

$>ps -aef | grep mongo
502  8047     1   0 11:52AM ??         0:00.23 /usr/local/opt/mongodb/bin/mongod --config /usr/local/etc/mongod.conf 

$>sudo kill 8047

$>sudo mongod

---

我的类似错误通过在尝试运行mongod时删除“sudo rm/data/db/mongod.lock”文件得到解决。

---

现在你可以运行mongod，然后运行mongo。

如果你已经安装了MongoDB，那么首先尝试以sudo用户的身份运行mongod，因为我没有以超级用户的身份运行mongod

我已经在底部粘贴了两个命令（mongod和sudo mongod）的o/p，您也可以检查，但是

先试试这个

sudo mongod

mongod

不是这个

sudo mongod

mongod

通过依次运行以下命令，我已经在MAC OS X Sierra 10.12.6上安装了MongoDB

brew update
brew install mongodb --devel
brew services start mongodb

然后创建了一个目录，mongod进程将向其中写入数据，这是可选的，因为mongod进程默认接受该目录，请参阅

最后启动了mongod流程，如下所示

sudo mongod

在我的终端上输出mongod（失败）和sudo mongod（成功）命令

就是这样。

我用自制软件升级到mongo 3.6后出现了这个错误

日志

/usr/local/var/log/mongodb/mongo.log

包含消息

正在关闭，代码为62

。此错误代码表示现有数据库太旧，无法使用当前版本的mongo运行

我在另一个项目中找到了两种解决方案：

• 删除数据库文件夹（

  /usr/local/var/mongodb

  ）
• 或者按照

我选择升级。在我的例子中，这意味着我必须降级到3.4，在mongo控制台中运行命令，然后再次升级。Mongo要求您一次升级一个主要版本，因此，根据您所处的位置，可能还有其他步骤。这些文档将指导您

---

brew开关

和

brew服务重新启动

命令使版本之间的切换相对轻松。

我也遇到了同样的问题，在查看日志文件时，我看到了以下内容：

{2019-03-09T11:57:32.136-0500 I STORAGE  [initandlisten] 
exception in initAndListen: NonExistentPath: 
Data directory /usr/local/var/mongodb not found., terminating}

因此，我创建了目录

/usr/local/var/mongodb

---

发出brew services restart mongodb命令后，我可以打开mongo控制台。

对于在mac更新到OS Catalina后在此寻找答案的任何人

跑

您确定mongo

brew services start mongodb-community
