#!/bin/bash
# Update on 2024/05/29
# 1. use wget to fetch latest frp version when curl was not installed
# 2. Remind users that frp will be run in non-root user
# 3. Add CI
#
# 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

systemctl status frpc
systemctl status frps

echo '
frps and frpc are installed.
Modify /etc/frp/frpc.toml or /etc/frp/frps.toml
And then run

    systemctl enable frps
    systemctl start frps

or 

    systemctl enable frpc
    systemctl start frpc

to launch the services

Remove "DynamicUser=yes" in .toml files if you want frp run in root (which is not suggested for security reason).

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

Great script! Btw, you still need to install curl for the command at the beginning, otherwise it wouldn't install frp at all - thought you should know :)

I keep getting frps.service: Failed at step EXEC spawning /usr/bin/frps: Permission denied in my service logs. Running it outside of systemd, using sudo works just fine. Anybody have a clue?

I tried setting permissions, changing owners, etc.

Did you bind on a port <1024? If so, only root/sudo can do that

@pnxl haha truuue, good catch
