Following the previous article, my family has set up a global agent for V2ray. If it continues to run for too long, the memory will probably be too much, so I found a small script on the Internet and restarted it regularly.

# System requirements

This script must support systemd in the system. I use Ubuntu with systemd.

# tutorial

First, use the command script / usr/local/ restart to create a script file, and enter:

#!/bin/sh
systemctl restart v2ray

Create another service using the command nano /etc/systemd/system/restart.service，and enter：

[Unit]
Description=Restart V2Ray
[Service]
Type=simple
ExecStart=/bin/sh /usr/local/restart

Then create a timer, use the command timer / etc/systemd/system/ restart.timer, and enter:

[Unit]
Description=Retart
[Timer]
OnBootSec=24h
# how many hours to execute after the first startup
OnUnitActiveSec=24h
# how many hours will it be executed?
Unit=restart.service
[Install]
WantedBy=multi-user.target

The last step is to execute the following command to activate the timer:

systemctl start restart.timer && systemctl enable restart.timer
