mongo

-bash: mongo: command not found

You have to use mongosh with latest versions of mongodb
Just issue mongosh and see if you can connect(assuming you already have a mongod up & running)
Regarding errors while starting mongod it appears to be permissions issues
Also your prompt indicates you tried to start it as root
Do not start mongod as root.Bring it up as normal user and use sudo privileges wherever you need root privs like to start service,create dir etc
Also check ownership/permissions on that TMP sock file

How do I check ownership/permissions of that TMP sock file?

Now it’s like this

mongosh
Current Mongosh Log ID: 63c8617aa251ba8aa3ee901a
Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.6.2
MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017

sudo service mongod start
Redirecting to /bin/systemctl start mongod.service
Job for mongod.service failed because the control process exited with error code. See “systemctl status mongod.service” and “journalctl -xe” for details.

I’m trying to access via ssh
mongodb on centOs server 7
me on pc fedora 37 with vscode

On your Centos machine check this
ls -lrt /tmp/mongodb-27017.sock

Remove TMP file and try to start mongod again
sudo systemctl start mongod
