This website has been one of my first explorations into doing any sort of web programming, and as result, has taught me a lot about different computing concepts from networking to encryption to system processes. At the start, I was running this service pretty simply over
https. Since the content is largely static and doesn't really include any sensitive information, adding support for TLS to accommodate
https wasn't a high priority.
The site uses the Rocket web server, which basically requires typing in
$ cargo run --release into the
site directory, which will use the specified compilation profile to bind to the given port. For http-only, this is usually Port 80; for https, Port 443. However, Rocket doesn't automatically run in the background, so if you want to exit your SSH session.
I tested this first using a Odroid-N2+1 that I use as test machine in my homelab. However, as mentioned on my site's About page, I host this site using a Digital Ocean droplet, which has a different directory structure from the Armbian user profile that I'm using on the N2+, where the standard user files are located a
/home/user. Instead, the Droplet has files (by default) at
/root. Keep this in mind when switching configuration paths between the test and "production" (everything's relative, right?) environments.
# A file with this information goes at /etc/systemd/system/site.service [Unit] Description=Website (cmoran.xyz) After=network.target StartLimitIntervalSec=1 [Service] Type=simple Restart=always RestartSec=1 User=root WorkingDirectory=/root/site # ExecStart requires an absolute path ExecStart=/root/site/target/release/site [Install] WantedBy=multi-user.target
From there, we can
# Reload the systemd service configuration files $ sudo systemctl daemon-reload $ sudo systemctl enable site.service $ sudo systemctl restart site.service
During this process, I like to keep an eye on what's actually happening in the system. The easiest way to do this is through
journalctl using the command
# Move to end (-e) of the file and follow (-f) $ journalctl -e -f
but most of the important information will also appear if you use the command
# Follow (-f) the tail end of the syslog $ sudo tail -f /var/log/syslog
The N2+ a great little machine, but if you're in North America and considering a purchase, I'd suggest using Ameridroid instead of Hardkernel. I at one point purchased an Odroid-C4 directly from Hardkernel which quickly developed some hardware issues. Getting an RMA notice from Hardkernel didn't take too long, but the shipping cost to/from the United States to their factory would have been over twice the cost of buying a new board. On the other hand, I haven't any issues with Ameridroid-purchased boards, but their customer support for things like making small order modifications has been really great, and I've been a pretty happy customer for a number of SBC-related part orders. ↩
