Question

我想使用systemd自动启动我的脚本，该脚本执行git checkout，git pull（我确定不会发生冲突），然后运行python程序。我创建了显示任务的示例。但是它会定期崩溃。设置“ TimeoutStartSec = infinity”是否正确？也许我必须以其他方式来做到这一点？

TEST_DAEMON.py

#!/usr/bin/python3.7
while True:
    pass

TEST_DAEMON.sh

#!/bin/sh
cd /home/user/TEST_DAEMON/
git checkout master
git pull
/home/user/TEST_DAEMON/TEST_DAEMON.py

TEST_DAEMON.service

[Unit]
Description=TEST_DAEMON SERVICE

[Install]
WantedBy=multi-user.target

[Service]
Type=forking
User=user
PIDFile=/var/run/test_daemon.pid
WorkingDirectory=/home/user/TEST_DAEMON
ExecStart=/home/user/TEST_DAEMON/TEST_DAEMON.py
Restart=always

==================================

sudo systemctl status TEST_DAEMON.service
