Sudo systemctl start mongod not working

peter_parker · 2022-03-27T16:47:19.422Z

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.

Ramachandra_Tummala · 2022-05-02T12:55:49.759Z

steevej i think you meant incompatible

stark_jatt · 2022-05-02T13:49:22.386Z

I don’t understand what want to say
Please answer me in docs type

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
Check this link

MongoDB Community 5.0.12 Illegal instruction (core dumped) ubuntu 20.04.5 LTS Ops and Admin

Hi there, I’m trying to get MongoDB 5.0.12 running on ubuntu 20.04.5 LTS, but whenever I try to start the mongod service through systemctl, I get the below output. user@ubuntu:~$ sudo systemctl start mongod user@ubuntu:~$ sudo systemctl status mongod ● mongod.service - MongoDB Database Server Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled) Active: failed (Result: core-dump) since Wed 2022-12-14 10:43:06 UTC; 4s ago Docs: https://docs.mongo…

Remove the mongodb-27017.sock file:

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

Then start mongod service again:

sudo systemctl start mongod
