[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

[phenomlab]

@ahmed I never stop the database when backing up. Never did it with mysql either. I’m not saying it’s right but it’s always worked for me and the backup schedules I’ve created for others who have used that to perform recovery.

[ahmed]

@phenomlab

I’m trying to take a backup while Mongodb is running, but this time it gives an authentication error.

[phenomlab]

@ahmed are you backing up remotely?

Try this - obviously, substitute where necessary to match your environment

mongodump -u root --password 'secret' --authenticationDatabase admin
