Mongodb 无法在 Ubuntu 15.04 中启动

Mongodb not able to start in Ubuntu 15.04

提问by M.J

I have installed MongoDB 3.0.6 in Ubuntu 15.04 using the following commands.

我已经使用以下命令在 Ubuntu 15.04 中安装了 MongoDB 3.0.6。

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/3.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
sudo apt-get update
sudo apt-get install -y mongodb-org

In the end in the installation process I got this:

最后在安装过程中我得到了这个：

Job for mongod.service failed. See "systemctl status mongod.service" and "journalctl -xe" for details.
invoke-rc.d: initscript mongod, action "start" failed.
dpkg: error processing package mongodb-org-server (--configure):

After that when I start the server using the below command I get an error and the server is not started.

之后，当我使用以下命令启动服务器时，出现错误并且服务器未启动。

sudo service mongod start

And the error is

错误是

Job for mongod.service failed. See "systemctl status mongod.service" and "journalctl -xe" for details.

Now when I run:

现在当我运行时：

sudo systemctl status mongod.service

I get the following:

我得到以下信息：

有人请帮忙，我是 Ubuntu 和 MongoDB 的新手，我不明白是什么问题。

There is a log file: /var/log/mongodb/mongod.log

有一个日志文件：/var/log/mongodb/mongod.log

In the log I've found the following:

在日志中，我发现了以下内容：

Failed to unlink socket file /tmp/mongodb-27017.sock errno: Operation not permitted

Most probably this was from previous MongoDB version. I deleted the file (rm -rf /tmp/mongodb-27017.sock) and finished the installation:

这很可能来自以前的 MongoDB 版本。我删除了文件（rm -rf /tmp/mongodb-27017.sock）并完成了安装：

apt-get install mongodb-org

Now it works. :-)

现在它起作用了。:-)

Recently i ended up with same issue and i tried all the possible solutions explained up here. But it didn't worked out for me. I was getting the below error.

最近我遇到了同样的问题，我尝试了这里解释的所有可能的解决方案。但这对我没有用。我收到以下错误。

# sudo service mongod restart
Restarting mongod (via systemctl): Job for mongod.service failed because the control process exited with error code. See "systemctl status mongod.service" and "journalctl -xe" for details. [FAILED]

Eventually i figured out the solution which worked for me. I went to /run/mongodbfolder and deleted the file called mongod.pid. Then tried to restart the mongo using # sudo service mongod restartand it's worked!

最终我想出了对我有用的解决方案。我去了/run/mongodb文件夹并删除了名为mongod.pid. 然后尝试使用重新启动mongo# sudo service mongod restart并且它起作用了！

My log said:

我的日志说：

[initandlisten] Found an invalid index { v: 2, key: { version: 1 }, name:   "incompatible_with_version_32", ns: "admin.system.version"

so:

所以：

 $cd /var/lib
 $sudo rm -rf ./mongodb
 $sudo mkdir mongodb
 $sudo chown -R mongodb.mongodb mongodb/
 $sudo service mongod restart

and then all worked fine.

然后一切正常。

• Make sure that the /data/dbdirectory exists

• Make sure your user have write privileges in that directory:

  $ sudo chown id -u/data/db

• Execute mongod

• 确保/data/db目录存在

• 确保您的用户在该目录中具有写入权限：

  $ sudo chown id -u/data/db

• 执行 mongod

If you still have problems and if the file /data/db/mongod.lockexists, remove it and execute mongod --repair.

如果仍然有问题并且文件/data/db/mongod.lock存在，请将其删除并执行mongod --repair.

The first thing you should check is a mongodb log file located at /var/log/mongodb/mongod.log

您应该检查的第一件事是位于 /var/log/mongodb/mongod.log 的 mongodb 日志文件

Look for the line with status Econtaining words like 'failed', 'fatal', etc.

查找状态E包含“失败”、“致命”等词的行。

I was having the same issue, after searching I got the answer that, when I executed

我遇到了同样的问题，搜索后我得到了答案，当我执行

sudo service mongod restart

I changed the permissions from user mongodb to root of the database folder, so the service was not able to read the data. So to solve I just reverted the permissions back to the user mongodb

我将用户 mongodb 的权限更改为数据库文件夹的根目录，因此该服务无法读取数据。所以为了解决我只是将权限恢复给用户 mongodb

sudo chown -R mongodb:mongodb /path-to-db-folder
sudo service mongod restart
