I have downloaded the newest version of mongodb and have moved and renamed the file to mongodb to the directory usr/local/mongodb . When I try to run mongod i get the following error

`./bin/mongod --help` for help and startup options

Answer 1

sudo chown -R <your-username> /data/db

Which user runs mongod? Are you running it with your regular login?

Answer 2

与“Joe Frambach's”相同，但是更容易切割和粘贴。

sudo chown -R $(whoami) /data/db

Answer 3

systemctl kicks in because the init-script for mongod sources this file like most others:

. /etc/rc.d/init.d/functions

The block with chkconfig comments is used to define the config and pid-file:

# config: /etc/my-mongod.conf
# pidfile: /var/run/mongo/mongo.pid

But that pifile's path should match up with whatever you have in config's dbpath. So this in /etc/my-mongod.conf

dbpath = /home/mongodb/2.0.5/data

Matches with this comment in /etc/init.d/mongod

# pidfile: /home/mongodb/2.0.5/data/mongod.lock

Answer 4

得到了同样的错误，在运行管理员权限的Windows中解决了问题。

Answer 5

以下命令对我有用：

sudo chown -R `id -u` /data/db
