Hello,

I installed mongodb according to https://www.mongodb.com/docs/manual/tutorial/install-mongodb-on-ubuntu/ on ubuntu 20.04. I adhered the guide and did not change any configuration files or anything else. Now, when I run “sudo systemctl start mongod” the terminal just executes the command but no output is produced. Running “sudo systemctl status mongod” gives:

mongod.service - MongoDB Database Server
     Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Sun 2022-03-27 15:18:13 CEST; 19s ago
       Docs: https://docs.mongodb.org/manual
    Process: 54971 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=exited, status=14)
   Main PID: 54971 (code=exited, status=14)

Can somebody tell me what I have done wrong? Many thanks!

@peter_parker We may not be able to tell you what’s wrong but the system logs should be able to tell you!

cd /var/log and check the syslog and any mongo* logs.

Thanks for your answer, it turns out that I had to change the write permission to the /var/lib/mongodb folder

It terminated with SIGILL it means your CPU is INcompatible with the version of mongod you are trying to use.

Search the forum with signal=ILL for potential solution.

Thanks @Ramachandra_Tummala for the correction.

The CPU in your laptop is probably an i5-520M.
That CPU does not support the AVX instruction.
Therefore, it will not run the latest versions of MongoDB.

ILL means illegal instruction
I think your cpu architecture not supporting the mongodb you are installing

Remove the mongodb-27017.sock file:

sudo rm -rf /tmp/mongodb-27017.sock

Then start mongod service again:

sudo systemctl start mongod
