Mongodb or Redis

phenomlab

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

https://wiki.archlinux.org/title/MongoDB

Madchatthew

@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?

phenomlab

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

Madchatthew

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

Madchatthew

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.

phenomlab

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

Perhaps try this

https://ivansaul.gitbook.io/blog/how-to-install-mongodb-on-arch-linux

Madchatthew

@phenomlab I am going to install it again here and I will post the error that I received.

Madchatthew

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.

Madchatthew

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

@Madchatthew not sure about the incompatibility, but did find this

https://www.mongodb.com/community/forums/t/setting-up-mongodb-v5-0-on-ubuntu-20-core-dump-status-4-ill/120705

Madchatthew

@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.

https://superuser.com/questions/1814515/mongodb-error-failed-with-result-core-dump

Madchatthew

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.

Madchatthew

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

Madchatthew

@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.

phenomlab

@Madchatthew can you post the configuration you have for the service?

Madchatthew

@phenomlab

This is the Nginx conf file

upstream io_nodes {

        }

        location / {
                proxy_pass http://io_nodes;
        }
}

This is the current nodebb.service file

I started with this code and the above code is from a google search. This code below, I did also try it with the correct path for node.

The “/usr/bin/env node” is where node is located that I found from using a command.
I also get a 502 Bad Gateway when I start either ./nodebb start or node loader.js.

When I do “sudo systemctl status nodebb” after using “sudo systemctl start nodebb”, I get the following.

Sorry this post is so long and thank you for your help.

Update: I just ran the status for nginx and received the below. So the 192.168.1.10 is my windows PC and the connection was refused. Would I need to add the port to ufw in order for this to work, or is this a different issue.

Update: adding those ports to ufw did not fix it.

phenomlab

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

What’s the output of

./nodebb log

Madchatthew

@phenomlab

[nodebb@morecowbell public_html]$ ./nodebb log

Hit Ctrl-C to exit


tail: cannot open './logs/output.log' for reading: No such file or directory

phenomlab

@Madchatthew hmm. That doesn’t look like it’s properly installed, or you have a permissions issue. What user are launching NodeBB as?

Can you try

./nodebb dev

Madchatthew

@phenomlab said in Mongodb or Redis:

I will give this a try this evening. At work now.
