MongoDB : Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused
提问by Ernesto Rojas
My problem is similar to other inputs and suggestions on this site, but none has helped me. After installing MongoDB, has not started because the database is not running.
我的问题与本网站上的其他输入和建议类似，但没有一个对我有帮助。安装MongoDB后，一直没有启动，因为数据库没有运行。
First try to run mongo and I answered this:

回答by Adam Comerford
Are you running all of these commands in the same terminal as separate actions as your timestamps suggest? (if not, I would expect to see overlap between the failures and logs in order to diagnose properly).
您是否按照时间戳建议在同一终端中运行所有这些命令作为单独的操作？（如果没有，我希望看到故障和日志之间的重叠，以便正确诊断）。
If so, then what you are doing is as follows:
如果是这样，那么你正在做的事情如下：
- Starting a shell, attempting to connect to a non-running database (connection refused)
- Starting the database, seeing 0 connections in the logs
- Stopping the database (Ctrl-C or similar), starting a shell, fails to connect again because database has been shut down
- Starting the database, seeing 0 connections in logs
- repeat
- 启动一个 shell，试图连接到一个非运行的数据库（连接被拒绝）
- 启动数据库，在日志中看到 0 个连接
- 停止数据库（Ctrl-C 或类似），启动 shell，由于数据库已关闭而无法再次连接
- 启动数据库，在日志中看到 0 个连接
- 重复
The database needs to be running concurrently with the shell so you can connect to it. Hence you should start the mongodprocess in one terminal, leave it running, and then open a new terminal (or tab) and run the mongocommand to connect to the still running database. The other option is to run mongodas a daemon, which will allow you to run the mongocommand in the same terminal once it returns.
数据库需要与 shell 同时运行，以便您可以连接到它。因此，您应该mongod在一个终端中启动该进程，让它继续运行，然后打开一个新终端（或选项卡）并运行mongo命令以连接到仍在运行的数据库。另一种选择是作为 daemon运行mongod，这将允许您mongo在返回后在同一终端中运行该命令。
Note: you should never have a folder with 777 permissions, it is not required and is a significant security risk.
注意：您不应该拥有具有 777 权限的文件夹，它不是必需的，并且存在重大安全风险。

Just try this command.
试试这个命令。
sudo chown mongodb /tmp/mongodb-27017.sock
须藤 chown mongodb /tmp/mongodb-27017.sock
And
和
sudo service mongod restart
须藤服务 mongod 重启
回答by Raja Parivesh
Fixed!
固定的！
The reason was the dbpath variable in /etc/mongodb.conf. Previously, I was using mongodb 1.8, where the default value for dbpath was /data/db. The upstart job mongodb(which comes with mongodb-10gen package) invokes the mongod with --config /etc/mongodb.conf option.
原因是 /etc/mongodb.conf 中的 dbpath 变量。以前，我使用的是 mongodb 1.8，其中 dbpath 的默认值是 /data/db。新贵工作 mongodb（随 mongodb-10gen 包一起提供）使用 --config /etc/mongodb.conf 选项调用 mongod。
As a solution, I only had to change the owner of the /data/db directory recursively.
作为解决方案，我只需要递归地更改 /data/db 目录的所有者。
Like this: Go to"/data" location in the terminaland then type
像这样：转到终端中的“/data”位置，然后键入
sudo chown -R <username>:foldername
sudo chown -R <username>:foldername
For example:
例如：
sudo chown -R raja db/
sudo chown -R raja db/
回答by geekgarage
Hello just check if you created the /data/db path and if you did then give 755 permission with chmod.
您好，只需检查您是否创建了 /data/db 路径，如果您创建了，则使用 chmod 授予 755 权限。
