Is my Mongodb installation correct?

ahmed · 23 Mar 2024, 16:52

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

@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

https://www.fosstechnix.com/how-to-install-mongodb-on-ubuntu-22-04-lts/

ahmed · 23 Mar 2024, 17:13

@phenomlab
I am using mongodb 7 version

What code displays Config.json?

I’m just learning mongodb

phenomlab · wrote on 23 Mar 2024, 17:13

@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 · 23 Mar 2024, 18:57

@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.

For more information, see

https://www.mongodb.com/docs/manual/tutorial/configure-scram-client-authentication/#create-the-user-administrator

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

ahmed · 24 Mar 2024, 03:36

@phenomlab

phenomlab · 24 Mar 2024, 13:40

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

ahmed · 24 Mar 2024, 13:43

@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 · wrote on 24 Mar 2024, 13:43

@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 · 24 Mar 2024, 14:42

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

ahmed · 24 Mar 2024, 14:42

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

phenomlab · 24 Mar 2024, 15:53

@ahmed anytime

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