无法通过mongodb.conf更改mongodb中的dbpath [英] Unable to change the dbpath in mongodb through mongodb.conf

问题描述

我收到以下消息
initAndListen std :: exception:boost :: filesystem :: exists中的异常:权限被拒绝:"/vol/mongodb"，终止

I am getting the following message
exception in initAndListen std::exception: boost::filesystem::exists: Permission denied: "/vol/mongodb", terminating

/var/log/mongodb/mongodb.log

in /var/log/mongodb/mongodb.log

ls -al/vol/mongodb给出-
drwxrwxrwx 2 mongodb mongodb 4096 2011-08-07 12:10 ./

ls -al /vol/mongodb gives -
drwxrwxrwx 2 mongodb mongodb 4096 2011-08-07 12:10 ./

当我更改dbpath时，将其恢复为默认值，即/var/lib/mongodb-它可以正常工作.

When I change the dbpath, back to the default, which is /var/lib/mongodb - it works fine.

我该如何解决?

推荐答案

最初我遇到相同的问题，发现这是由mongodb用户对父级目录没有适当权限引起的.

I had the same problem initially and found it was caused by the mongodb user not having appropriate permissions on the parent directory.

我建议检查/vol以确保mongodb用户至少可以从该目录读取文件.可能还需要执行权限，我怀疑此权限将保留在每个后续的父目录中，直到根目录为止.

I'd recommend checking /vol to ensure that the mongodb user can at least read files from that directory. May also need execute permissions too, and I suspect this will hold for each subsequent parent directory up to root.
