Question

我试图启动计算机的mongodb服务但它无法启动。我花了一个多小时试图调试它，在那段时间我尝试了很多解决方案。尝试所有这些可能搞砸了我的mongo安装，但我尝试重新安装mongo以获得一个新的开始。那也行不通。我现在有以下错误，在谷歌上找不到任何关于如何修复它的内容。

我正在运行Ubuntu 16.04。

Answer 1

这是日志的有说服力的部分：

/var/lib/mongodb/journal/WiredTigerPreplog.0000000002: file-remove: unlink: Permission denied

所以看看ls -la /var/lib/mongodb/journal，看看这些文件的权限是什么。我敢打赌那些（可能是其他人）没有被正确的用户正确拥有，在Ubuntu上通常是mongodb。

假设您在那里遇到了所有权问题，您可以运行chown -R mongodb:mongodb /var/lib/mongodb。

如果这不起作用，作为最后的手段，您可以随时通过运行rm -rf /var/lib/mongodb/*来清除数据目录（假设您不需要数据！）。

Mongo不会开始。得到神秘的断言：28595：13：权限被拒绝错误
