64bit的Mongodb 3.4 Ubuntu 16.04 mongodb-27017.sock错误

Question

有几个帖子与Mongodb 3.2有关，但是当我尝试安装3.4时，启动不会发生。相反，日志文件中会出现一个不寻常的错误（显示在列表的最后）。 这可能是因为安装了旧版本？ 我做了一个apt-get删除和清除。 有人可以提出为什么会出现错误吗？

我也跟着下面的步骤，所概述here，

$ sudo apt-get remove mongodb* 
$ sudo apt-get purge mongodb* 
$ sudo rm -rf /usr/lib/mongodb 
$ sudo rm -rf /usr/log/mongodb 
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6 
$ echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list 
$ sudo apt-get update 
$ sudo apt-get install -y mongodb-org 
.. 
.. 
E: There were unauthenticated packages and -y was used without --allow-unauthenticated 

$ sudo apt-get install mongodb-org # removed -y to get it going 
.. 
.. 


Setting up mongodb-org (3.4.2) ... 
$ sudo chown -R mongodb:mongodb /var/log/mongodb 
$ sudo chown -R mongodb:mongodb /var/lib/mongodb # modified ownership in view of what is stated on the mongodb installation note 

$ # created the following file 
$ cat /etc/systemd/system/mongod.service

Answer 1

@mcgraddy，谢谢，这确实有帮助。创建目录并复制服务文件是答案。

$ sudo cp /etc/systemd/system/mongod.service /etc/systemd/system/mongodb.service 

$ sudo mkdir -p /data/db 
$ sudo chown -R $USER:$USER /data 

我必须更改/ data的所有权。 启动服务和查看状态显示一切运行如预期：

$ sudo service mongod start 
$ sudo systemctl status mongodb

Answer 2

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

这意味着mongod的过程是由root启动user.So你可以删除sock文件或运行此命令来解决这个问题问题：

sudo chown `whoami` /tmp/mongodb-*.sock 

确保端口分配应该是可访问，而不是阻止你的防火墙，然后就重启星期一上帝的过程。

控制台输出中的等待连接消息指示 mongod.exe进程正在成功运行。

您可以检出​​。

希望这会有所帮助。
