I don't know if you need to get rid of the domain folder, but you do need to set up the reverse proxy.
Lost all my data ? Help please
-
Is someone here can explain me where to find if I have a backup.. How can I just lose all my data without a reason ?? Please someone explain me what's could have happened to my website ? I lose a nine months of hard work !!!
What's command I have to execute to try restoring my datas ?
-
@bitspook I don't want to throw out blind judgement here... Since I never used Digital Ocean. I've always used my own full scale dedicated. But does someone experience issue's with MongoDB and Digital Ocean? And like many people over NodeBB said, keep making backups.
Edit: I'm also wondering on what scale database wipes occur. They seem to be pretty rare. -
@Kowlin not that it couldnt be Digital Ocean; just that the correlation is anecdotal as of yet.
-
@bitspook Who knows, maby its a blind curse
. Anyways is someone running more Node.JS apps or Redis databases on there servers? Did those get wiped at one point or another? -
If you had Redis persisting to disk, it would be at
/var/lib/redis.It sounds like someone (or some script, rather) is going around trying to connect to port 6379, and if successful, flushing the database.
Better use AUTH and have good backups!!

@kacemlight This seems to be the case. I am able to connect to the redis server at nodejsworld.com:
$ redis-cli -h nodejsworld.com nodejsworld.com:6379> keys * 1) "sess:0d5qvchIPxvQ-lsGNTJkWL7s1SQBrd8v" 2) "ip:recent" 3) "schemaDate"Please take a look at this topic: http://redis.io/topics/security.
I realise this is a very rough time for you, @kacemlight, as you've lost your site data. I have every confidence that you will be more careful in the future and utilise backups in addition to setting up authentication for your database.
-
@julian Always a posibility too be honest. I'll have some fun opening my Redis port tonight to my server. Not like I have critical data on there anyways.
-
@Kowlin I've found the easiest way is to just use
ufw. If you only connect from one PC, then disallow requests from all IPs except your own, and set the default behaviour toDENY. -
Well am I the only one a bit troubled about the fact that the default Redis security is so easy to avoid. I opened my Redis port from my router and connected to it without any single problem...

Did you take a backup of any sort?
-
@julian @Kowlin Redis is that bad? Did not know that. Planned on migrating to Mongodb before production anyway

Is someone now why this happen ?!! Is it can be related to the hosting provider Digitalocean ?
That would not make any logical sense. DO is only your IaaS platform and does not touch the system itself. You would not suspect a hardware vendor in a physical deployment of deleting your database.

IIRC the default Redis config is "bind to 0.0.0.0", which means open to everyone. Might be the same with Mongo.
However, Ubuntu locks these configs down by binding to localhost only, so installing via
apt-getis usually better than installing by downloading and compiling on your own. -

That is expected. That means that the firewall is open on your OS (is the firewall running?) and Redis does this because it is designed to be in a cluster and would need the port open to talk to itself or to a Sentinel.

maliciously?
-
@bitspook Probably.
Looks like antirez added a large warning block about it here, and it may be uncommented by default now...
https://github.com/antirez/redis/blob/unstable/redis.conf#L40-L61 -
Just bind redis to localhost. Then it's won't be accessible from the outside world.
By default redis listens to all interfaces which means all external ips (unless you have some firewall in place)./etc/redis/redis.conf:add
bind 127.0.0.1Edit: Damn @julian you beat me.
-
@julian If this doesn't happen can we atleast add a warning to the NodeBB documentation for this?
-
Please if we supposed the backup was actived by default, how can I find the dump.rdb ? or maybe how can I check if it's activated ? I just want to be sure that there is no hope to get back my website. That's mean I lost nine months of work and now I will give up and stop hosting it...
