我的服务器运行在Nginx Ubuntu 16.04 LTS上。 我想安装mongoDB使用node.js然后我按照这个教程，但是当我写状态命令我有这个。
● mongodb.service - High-performance, schema-free document-oriented database Loaded: loaded (/etc/systemd/system/mongodb.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Tue 2016-07-26 20:21:15 CEST; 7s ago Process: 4527 ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf (code=exited, status=14) Main PID: 4527 (code=exited, status=14) Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: Started High-performance, schema-free document-oriented d Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: mongodb.service: Main process exited, code=exited, status Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: mongodb.service: Unit entered failed state. Jul 26 20:21:15 ns3039456.ip-94-23-252.eu systemd[1]: mongodb.service: Failed with result 'exit-code'. 你有任何解决scheme来解决我的问题？ 如果你有一个解决scheme，需要完全删除MongoDB没关系。 我没有在我的数据库中，因为这是我的第一个安装。
我试过这个命令来删除mongodb：
sudo apt-get remove mongodb* --purge
但是我有这个错误
E: Unable to locate package mongodb.service E: Couldn't find any package by glob 'mongodb.service' E: Couldn't find any package by regex 'mongodb.service'
但我喜欢教程说。 我在/etc/systemd/system创build了mongo.service文件
编辑：
用mongod命令我有这个：

错误是不言自明的，你的系统上缺less/etc/mongodb.conf文件，所以你需要创build一个。 这个简单的configuration将允许你启动mongod
systemLog: verbosity: 1 quiet: true traceAllExceptions: false path: "/opt/mongo/log/local.log" logAppend: true destination: file storage: dbPath: "/opt/mongo/db" journal: enabled: true processManagement: fork: true net: port: 27017 security: authorization: disabled
只需为日志/存储设置合适的path，并确保mongod能够在那里写入。
