MongoDB忽略配置文件中的dbPath

Question

I'm setting up a fresh centOS 7 install following these instructions.
https://docs.mongodb.com/v3.0/tutorial/install-mongodb-on-red-hat/

Using systemctl start mongod I get a error saying /data/dbs does not exist (which it doesn't). If I run
sudo mongod -f /etc/mongod.conf Everything seems to work. I don't really want to edit the init script if I can avoid it, but is there any way to fix this?

Answer 1

If you are installing using yum in CentOS7 by using the repository file described in Configure MongoDB v3.0 yum , the MongoDB instance stores its data files in /var/lib/mongo and its log files in /var/log/mongodb by default , and runs using the mongod user account.

the default config should contain a section similar to:

storage:
    dbPath: /var/lib/mongo
    journal:
        enabled: true

Make sure whether there's no modification made to the content of your /etc/mongod.conf .

Answer 2

So the solution has ended up just being a new service which calls mongod with the parameters I want. I've disabled the default mongod service systemctl disable mongod Added my service file to /etc/systemd/system and enabled it systemctl enable my-mongod It works well enough and shouldn't be broken by updates as they come down. The only thing that threw me for a bit is that the service had to be of type forking for it to work.
