Init script?

Init script?

[DuraMorte]

That must be a leftover from my futile attempts to get a script working before... I'm investigating. Thanks!

[DuraMorte]

So, in total, there will be Mango files in three places:

1. the database files, located at ~/mango
2. the binary, located in /usr/local/bin/
3. the config file, located at ~/.config/mango

I got that all straightened out, and sure enough, #19 went away as well. I don't know how I managed to misplace the files like that, but I appreciate you noticing my error. :)

[DuraMorte]

Disregard. Found it. :)

This repository does not include a startup script. Where did you find it?

If mine is acceptable, I'd be happy to contribute it.

Sure! Contributions are always welcome. Feel free to submit a pull request if you want :D

[DuraMorte]

I forgot; I tried to write my own a while back, but I couldn't get it to work, and then forgot about it. If I can get it working, I'll send it to you.

I see. I think it might be helpful for other users as well. I will work on this and write one, but feel free to contribute if you can get yours working.

I am reopening this issue.

I updated the Wiki and included a sample systemd script there. Cheers.

[DuraMorte]

I tried to implement the script on Ubuntu Server, and it doesn't work.
Below is the error message I'm getting:

● mango.service - Mango manga server service.

Any ideas on what could be causing this?

[hkalexling]

Process: 9004 ExecStart=/bin/bash /usr/bin/mango (code=exited, status=126)

Here you are telling systemd to run the mango binary file using bash. /bin/bash can only run bash scripts and not binary files, and that's why you got the error. Try replacing it with

ExecStart=/usr/bin/mango

which runs the binary directly.

[DuraMorte]

Reworked some things, now I'm getting a new error.

journalctl -xe shows this:

Any ideas? I hate to bombard you with this, but it would be super helpful if I didn't have to worry about starting the server manually every time I reboot the VM.

[hkalexling]

Don't worry; I am always happy to help!

This looks like a permission issue. Can you check that the file /usr/local/bin/mango is executable? You might need to run chmod +x /usr/local/bin/mango.

It would be helpful if you could run ls -l /usr/local/bin/mango and paste the output here.

[DuraMorte]

"user"@ubuserv:/usr/local/bin/mango$ ls -l /usr/local/bin/mango
total 19900
-rwxrwxrwx 1 "user" "user" 19438840 Mar 20 18:10 mango
-rwxrwxrwx 1 "user" root 884736 Mar 20 14:48 mango.db
-rwxrwxrwx 1 "user" root 45056 Mar 15 22:16 queue.db

I can, generally, identify permissions issues by running a chmod 777 * then testing. Unfortunately, this time it isn't quite doing the job. :(

[DuraMorte]

Works when I run as root. Trying to get away from doing everything as root. Is Mango necessary to run as root?

[hkalexling]

Did you move the entire folder that was supposed to be at ~/mango to /usr/local/bin? You should put only the binary file there. That is, /usr/local/bin/mango should be a single binary file, but from the ls output above it looks like it's a folder on your system.

I guess #19 is also related to this. The two files mango.db and queue.db are the sqlite database files. Moving them there might have confused Mango.

Please try to:

1. Move the mango folder back to where it was
2. Move only the mango binary file inside the mango folder to /usr/local/bin

Is Mango necessary to run as root?

No, and you are not supposed to. That's why in the Wiki I suggest running the service using systemctl --user instead of sudo systemctl.

[hkalexling]

Yup, you are right. Glad to know that it's working now!
