Is my Mongodb installation correct?

[ahmed]

@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.

For more information, see

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

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

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

[phenomlab]

@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

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

@ahmed the database needs to be running to use MongoDump.

[ahmed]

@phenomlab

Nodebb.org documentation states that Mongodb must be stopped before backup
nodebb.org documentation should be updated
I think I saw it wrong

I will try as you say
