node.js – MongoDB – 用代码关闭：100

我一直在尝试在我的Ubuntu 16.04.2 LTS(GNU / Linux 4.4.0-22-generic x86_64)VPS上设置MongoDB,我遇到了一些问题.我作为用户在我的服务器上运行,具有root访问权限但不使用root帐户本身.

当我在admin数据库上执行db.createuser()时,我开始注意到这个问题,所以我可以添加其他用户,我收到了这个错误：
没有授权执行命令

然后我继续使用网站上提供的教程再次卸载和安装：https://docs.mongodb.com/v3.2/tutorial/install-mongodb-on-ubuntu/

现在,当我在第2阶段时,验证MongoDB是否已在Run MongoDB Community Edition部分成功启动,即我查看文件/var/log/mongodb/mongod.log中的输出,我得到以下内容：

我环顾四周,这是错误as found here,因为这与我没有/ data / db文件夹的事实有关.从该日志中我可以看到它与此行有关：

2017-04-14T14:23:09.366+0200 E STORAGE  [initandlisten] WiredTiger error (2) [1492172589:366629][9691:0x7f1755946cc0],connection: /var/lib/mongodb/WiredTiger.wt: handle-open: open: No such file or directory

这是真的,当我转到/ var / lib / mongodb并执行ls -l时,结果如下：

drwxr-xr-x 2 mongodb mongodb 4096 Apr 14 14:10 journal
-rw-r--r-- 1 mongodb mongodb    0 Apr 14 14:02 mongod.lock
-rw-r--r-- 1 mongodb mongodb    0 Apr 14 14:10 WiredTiger
-rw-r--r-- 1 mongodb mongodb   21 Apr 14 14:10 WiredTiger.lock
-rw-r--r-- 1 mongodb mongodb 1004 Apr 14 14:10 WiredTiger.turtle

但我不知道我是否应该手动创建该文件,因为其他地方没有看到这个问题.我确保mongodb用户也拥有这些文件的权限,如in the answer to this question所述,但仍然没有运气.

我真的不知道该做什么,任何帮助都会非常感激,因为这是我第五次尝试让它发挥作用！

谢谢！

解决方法

这是MongoDB中的已知错误,请查看 report

问题不在于文件一般都缺失,而是在干净关闭后重新启动时它们会丢失.您的问题与/ data / db目录无关,但与重启后丢失的WiredTiger.wt文件有关.

错误报告谈论同样的事情.

尝试：

我建议尝试在配置文件中禁用WiredTiger.
