Mongod server not starting

Mohak_Goel · 2024-11-05T04:55:53.371Z

I successfully built MongoDB version 8 from source, but I’m encountering an error when trying to start the server. Here’s the error message:

Error:

If anyone has suggestions on resolving this issue, I’d greatly appreciate it.

What does your conf file say?

Mohak_Goel · 2024-11-06T05:27:30.640Z

Hi Mr. Jack,

Below is my config file content

MongoDB configuration file

Where and how to store data

storage:
dbPath: /data/db # Adjust this if your dbPath is different

Network interfaces

net:
bindIp: 127.0.0.1 # IP address to bind to
port: 27017 # Default MongoDB port

Process management

systemLog:
destination: file
path: /var/log/mongodb/mongod.log # Change path as needed
logAppend: true

Optional: security options

security:
authorization: enabled # Enable authorization if required

Mohak_Goel:

/data/db

Does this path actually exist?

In addition to

Does this path actually exist?

What does the log says?

Hello,
We are able to start the MongoDB server V8, V7 on Icelake (x86-64) machine. We are facing the issue that is mentioned above is with Graviton3(ARM) machine.
So we would like to know if the support for MongoDB in ARM for V8,V7 is still in progress or is there any work in progress in this aspect.

Hi Mr. Jack & Mr. Steeve,

Yes /data/db path exists and inside logs it is showing error only

inside logs it is showing error only

What is the error? Please share the content of the log.

Nice. By reading the error message in the log we can see that the error is:

Mohak_Goel:

Error creating journal directory
…
{“directory”:“/data/db/journal”
…
Permission denied

One of the most useful skill in programming and system admin is to be able to read.

@Mohak_Goel, I hope my replied reached you and that you were able to fix your file permission issues.

Please followup.

@Mohak_Goel, I have looked at your previous threads and it looks like you have the tendency to let them die off despite having answers from other users. It would be nice if you could change this behaviour.

Mohak_Goel · 2024-11-20T05:34:54.454Z

Hi @steevej,
Thank you for your support! The mongod server is now working fine.
