Is my Mongodb installation correct?

[ahmed]

Hi;
for nodebb
My Mongodb installation is in the pictures below.
Do you think my setup is correct?

root@localhost:~# sudo chown mongodb:mongodb /tmp/mongodb-27017.sock

@ahmed It looks correct, yes, but can you also post the contents of config.json? Also, which version of mongodb are you running?

You should also review this guide as it’s quite concise and very reliable

@phenomlab
I am using mongodb 7 version

What code displays Config.json?

I’m just learning mongodb

[phenomlab]

@ahmed Sorry - should have been clearer. What I meant by config.json is the config file from your NodeBB installation. From what I see, you have authentication enabled in the config, but it doesn’t work?

[phenomlab]

@ahmed before you can enable authorization, a valid admin user needs to exist in the database. Try disabling the authorization for the time being, restart MongoDB and then see if you can login.

I expect this will work, but once you are able to login, put the authorization back, restart MongoDB and then try it again.

@ahmed can you post the content of /etc/mongod.conf

@ahmed does the database service start if you remove the below

@ahmed that would have been my next suggestion in relation to permissions. Glad you got it working

[ahmed]

@phenomlab

[phenomlab]

@ahmed that’s normal if you haven’t started your nodebb instance, or competed the installation yet.

[ahmed]

@phenomlab
I reset my server and set it up again.
save as video
Can you check if it is installed properly?
especially the mongodb part

[phenomlab]

@ahmed can you provide me with a url I can reach the installation on? If you’d rather not place this here, you can use the PM to do so.

[phenomlab]

@ahmed thanks for the url. I’ll check this later.

[ahmed]

@phenomlab
Thank you for taking the time to answer my questions.

[phenomlab]

@ahmed anytime

[ahmed]

@phenomlab

What could be the reason why mongodb gives this error when trying to take a backup?
