I have a problem with the abilitation of encryptio

[stupeppe (Giuseppe Primerano)]

Hi, I’m a Universitary student and for my thesis i go to study the encryption in MongoDB. According with the tutorial present in the manual. I create the local key but at the moment to start MongoDB, the service don’t start. I tried to update the mongod.conf but the service never start.

After the reboot of my computer the service start, but the encryption isn’t enable.

I’m using the following components:

• MongoDB Enterprise v 5.0.5
• Ubuntu 20.04 Focal Fossa.

This is the error:

This is my configuration file before modification

# mongod.conf

# for documentation of all options, see:

# Where and how to store data.

Hi @stupeppe,

Check if there are the correct permission for
/var/lib/mongodb
/var/log/mongodb/mongod.log
And for
mongodb-27017.sock
Usually the mongodb-27017.sock is in tmp, so:
/tmp/mongodb-27017.sock

Welcome to the MongoDB Community Forums @stupeppe !

@stupeppe

/var/log/mongodb/mongod.log

If the MongoDB service doesn’t start up as expected, the first place I’d check is the log file. The last lines in the log file should indicate a reason the instance was unable to start.

Regards,
Stennie
