Install frp as systemd service

install-frp-as-systemd-service.sh

# Update on 2024/04/13
# 1. Improved OS compatibility: try wget and then curl for downloading files.
#
# Update on 2024/01/26
# 1. Thanks to GitHub user @aka-Ani, this script now will install latest version of frp:
#    https://gist.github.com/lawrenceching/41244a182307940cc15b45e3c4997346?permalink_comment_id=4851742#gistcomment-4851742
# 2. Use .toml conf file as .ini became lagacy
#
# Update on 2023/06/19
# 1. frp no longer provide systemctl service file. This script creates frpc/fprs systemctl service file by itself
# 2. Update frp from 0.33.0 to 0.49.0
# 3. User=nobody is no longer suggested, use DynamicUser=yes instead

It works pretty well!

May want to also grab these *.service files with the latest release (0.48 atm) fatedier/frp#3048 (comment)

@NickLucche I think that is possible. Just edit the version of frp.

@NickLucche
Uplifted frp to latest 0.49.0.

And other changes are listed at the top of script.

Thanks for this! just an aside, I changed all references of .ini files to .toml files (I think ini is deprecated as of 0.52.0)

Also for what its worth, the latest version could be determined in-script with something like this at the beginning:

# set platform (latest options as of 2024/01/25), choose one of:
#   darwin_amd64
#   darwin_arm64
#   freebsd_amd64
#   linux_amd64
#   linux_arm
#   linux_arm64
#   linux_mips
#   linux_mips64le
#   linux_mipsle
#   linux_riscv64
#   windows_amd64
#   windows_arm64

platform=linux_amd64

# download url can be determined by parsing the json of the releases/latest url. 
# each asset has a browser_download_url key, and we want the value where the platform is the one chosen above
d_url=$(curl -s https://api.github.com/repos/fatedier/frp/releases/latest | grep browser_download_url | grep $platform | head -n 1 | cut -d '"' -f 4)
echo "Latest version URL: $d_url"

# perform the download. using curl instead of wget for simpler macos cross-compatibility
curl -O --output-dir /tmp $d_url

DIR=$(basename $d_url .tar.gz)

<continue rest of the script as before>

@aka-Ani thanks for you contribution!

I realised after I made the comment that the switch from wget to curl for macos compatibility makes no real sense since systemd isn't even a part of macos anyway haha. It was just part of my process writing and testing the auto-latest-version download portion of the script. So feel free to change it back, but I suppose it doesn't matter too much lol

very helpful！ thanks

I actually prefer wget over curl, as debian in my specific environment (lxc in proxmox) has wget preinstalled, but not curl.
So since this cant be used on macOS anyway, I believe wget hat greater compatibility.

I agree!

@kelke @aka-Ani
thanks for your suggestion. I updated script to try wget first and then curl.

By the way, for anyone experiencing problems with binding on ports lower than 1024 in frps.toml:
I needed to remove the line: DynamicUser=yes from the frp-server systemd-config /etc/systemd/system/frps.service, as it seems the service then does not run as root.
Removing the line does run the service as root, so keep that in mind from a security-perspective.

The best systemd services of all! I've tried another services from different tutorials but yours are most reliable
