Create a systemd service script at /etc/systemd/system/xiexievpn.service, with the following content:
                [Unit]
                Description=xiexievpn Service
                After=network.target
                
                [Service]
                Type=simple
                ExecStart=/usr/local/bin/xray //这里/usr/local/bin/替换成你的实际解压路径
                Restart=on-failure
                LimitNOFILE=65535
                
                [Install]
                WantedBy=multi-user.target
                

Run the command:
echo -e '\nexport http_proxy="http://127.0.0.1:1080"\nexport https_proxy="http://127.0.0.1:1080"\nexport all_proxy="socks5://127.0.0.1:10808"' >> ~/.bashrc && source ~/.bashrc; systemctl daemon-reload; systemctl start xiexievpn
(Optional) systemctl enable xiexievpn

Set the system proxy:
GNOME Desktop:
Open “Settings” → “Network”, find “Network Proxy” or “Proxy” option. Choose “Manual” and set HTTP Proxy to 127.0.0.1, port 1080, or set “Socks Host” to 127.0.0.1:10808 if needed. If you want to exclude local addresses, add localhost, 127.0.0.1, ::1 into “Ignore Hosts”.

KDE Desktop:
In KDE, go to “System Settings” → “Network Settings” → “Proxy”. Then choose “Manual” and fill in 127.0.0.1:1080 / 127.0.0.1:10808.

Other Desktop Environments:
For XFCE, MATE, Cinnamon, etc., you can also find a similar “Network Proxy” or “System Proxy” setting to fill in the same information.
