Can'；t使用mongod&；启动MongoDB服务；蒙戈

您好，我的MongoDB有问题，它工作正常，在我重新启动服务器并取消一些东西后，出现了这个问题

当我运行命令时

$ mongo

它的反应是

MongoDB shell version: 3.2.13
connecting to: test
2017-05-29T01:11:42.948+0000 W NETWORK  [thread1] Failed to connect to     127.0.0.1:27017, in(checking socket for error after poll), reason: errno:111 Connection refused
2017-05-29T01:11:42.948+0000 E QUERY    [thread1] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed :
connect@src/mongo/shell/mongo.js:229:14

exception: connect failed

我也运行了这个命令

$ mongod

它给了我这个错误信息

***aborting after fassert() failure

然后我试着

sudo service mongod start
sudo service mongod status

它给了我这个失败的错误

我尝试删除套接字文件并尝试一下，但没有成功。

提前谢谢你！：）

我不确定这是不是正确答案。然而，在我看来

2017-05-29T01:17:58.469+0000 E网络[initandlisten]无法取消套接字文件的链接/tmp/mongodb-27017.sock错误号：1不允许操作

这是主要问题。也许你可以再核实一下谁拥有这个？还有许可证吗

在我的mongo中看起来是这样的：

希望它能对我有所帮助，因为我没有创建用户mongodb，所以root是所有者。这就是问题所在吗？请尝试描述解决方案，而不仅仅是使用代码。此外，日志表明Unix域套接字文件

/tmp/mongodb-27017.sock

，而不是锁文件存在问题。

rm /var/lib/mongodb/mongod.lock
systemctl restart mongod
systemctl status mongod
