Sudonix

Mongodb or Redis

General
  • Madchatthewundefined

    I was wondering which database you are using for nodebb. Are you using MongoDB or Redis? My guess is that you are using MongoDB. And why did you choose the one you did?

    I would also like to hear what others did as well.

    @Madchatthew Sudonix actually uses MongoDB and Redis together. Redis is used for the session states, whilst MongoDB is the main database where post information et al is stored. MongoDB is the preferred database engine, although there is support for Postgres.

    It’s also worth noting that Sudonix runs as a 3 node cluster as shown here

    @phenomlab That is awesome! So Redis can be installed on Arch. One of the issues I am having is getting Mongodb installed on Arch. I guess there is some licensing issue so it was taken off of the AUR. So I have been digging around the internet about how to get it installed, and even going as far as compiling it from source myself. I am not sure that is a viable option. The steps aren’t the easiest to to go through either. I love learning and will keep trying. One of the things about this project with Arch, is that just when I think I am understanding something, there is something else that I need to learn. It has been a great experience so far, challenging, but great.

    @Madchatthew MongoDB has been removed from the official repositories due to its re-licensing issues. See

    @phenomlab Yeah that is what I saw as well. I am wondering if these instructions would work?

    https://www.geeksforgeeks.org/how-to-install-mongodb-on-arch-based-linux-distributionsmanjaro/#

    I will try them and see tonight. I have my doubts, but it is pulling the mongodb-bin from the AUR so maybe. When I try pacman -S mongodb-bin it says that it can’t find it, so maybe these other instructions will work. I know they are for Manjaro but that is based off of Arch so possibly?

    @Madchatthew I see absolutely no reason as to why not. Looks like a well written guide - and I trust this site.

    @phenomlab Nice! I will try it tonight and let you know how it goes.

    So I tried several times to get Mongodb running on Arch but to no avail. I was able to install redis and get a nodebb instance setup and even proxied through nginx. And as expected, Nodebb is just superfast. I like how you don’t have to mess with making sure the proper php extensions are installed and make sure that path is entered in and all that jazz. It is nice to install it and it just works.

    I will have to keep attempting to install mongodb on Arch. Then I can use them both for Nodebb.

    @Madchatthew did you get any specific error message when trying to compile?

    I used these instructions to install mongodb
    https://www.geeksforgeeks.org/how-to-install-mongodb-on-arch-based-linux-distributionsmanjaro/

    This is what I see when I use ‘sudo systemctl status mongodb’ after starting the mongodb service

    I rebooted the server and the results were the same after rebooting the server.

    Here is the status in text form to make for easier searching.

    Process: 704 ExecStart=/usr/bin/mongod --config /etc/mongodb.conf (code=dumped, signal=ILL)

    I think the signal=ILL in the highlighted text means that it isn’t compatible with the OS after doing some searching.

    @phenomlab Yeah I found this one too that says the same thing. When I do the command to see if avx is on there, it doesn’t show anything. Also, my computer is 10 years old.

    I was able to figure it out with the help of this stackoverflow post linked below. Following these instructions I was able to get mongodb running and avx showed up in the cpu info. So I have this setup in virtualbox so on a hosted server, hopefully this wouldn’t be an issue, but if anyone else runs across this, hopefully it helps.

    To summarize the instructions:

Open a Command Prompt in Windows Host as Administrator.

Find the Command Prompt icon and right-click. Choose Run As Administrator.
Disable Hypervisor lunch

bcdedit /set hypervisorlaunchtype off

Disable Microsoft Hyper-V

DISM /Online /Disable-Feature:Microsoft-Hyper-V

Shutdown quick shutdown -s -t 2

Wait a few seconds before turn it on.

    Now the text task will be to migrate data from Redis to Mongodb and setup the multithread that @phenomlab has setup for this site.

  • Madchatthewundefined

    @phenomlab how do you have it setup to have this sight start up automatically if the server gets rebooted? I attempted to follow nodebb’s instructions but can’t seem to get the systemd nodebb.service instructions to work. I have also tried a few others that I googled for and it just doesn’t seem to want to run as a service.

    @Madchatthew connection refused typically means that port is being used elsewhere.

    What’s the output of

    ./nodebb log

    @veronikya said in mongodb replica set:

    The host’s local dns resolution is not configured. The problem of the host’s hosts being unable to be resolved in docker has been solved. Surprisingly
    Solution:
    Edit the /etc/resovel.conf file
    Add 127.0.0.53

    One immediate issue I can think of here is that editing resolv.conf directly is no longer supported and not recommended (because the changes do not survive a reboot) - unless you install the resolvconf package?

    @DownPW This isn’t something I have readily available, and because I’m not entirely familiar with the database structure of NodeBB, it’s something that would require research and development in terms of script.

    I think it’d be quicker to ask this in the NodeBB forums.
