Ubuntu 启动时无法运行 Python 脚本

我试图在 Ubuntu 启动时运行 Python 项目中的两个脚本，但一直出现问题。我有一个如下所示的 Python 项目：

  • pycharm
    • 韦恩
    • 日期.txt
    • 全局函数.py
    • 網絡.txt
    • 互联网日期.txt
    • 互联网时间日志.txt
    • 网络跟踪器
    • 停电.txt
    • 断电跟踪器.py
    • 时间记录.txt

项目路径为/home/connor/Documents/Pycharm，IDE为Python 3.8.10的虚拟环境

我尝试运行的两个文件是 internettracker.py 和 poweroutagetracker.py。这两个代码如下：

网络跟踪器

import requests
import time
import globalfunctions as gf

url = "http://www.kite.com"
timeout = 5


def ping_internet():
    try:
        request = requests.get(url, timeout=timeout)
        return True
    except (requests.ConnectionError, requests.Timeout) as exception:
        return False


gf.log_today(additional="internet")

while True:

    internet_connected = ping_internet()

    if internet_connected:
        datestring, timenumber = gf.get_log(additional="internet")
        curtime, today = gf.get_today()

        if abs(curtime - timenumber) > 35:
            gf.report_data("internet.txt", "Internet outage from [" + datestring + "] to [" + str(today) + "]")
            print("Internet Outage Detected")

        gf.log_today(additional="internet")
        time.sleep(30)
    else:
        time.sleep(15)

断电跟踪器.py

import time
from datetime import datetime
import globalfunctions as gf

while True:
    datestring, timenumber = gf.get_log()
    curtime, today = gf.get_today()

    if abs(curtime - timenumber) > 5:
        gf.report_data("poweroutages.txt", "Power outage from [" + datestring + "] to [" + str(today) + "]")
        print("Power Outage Detected")


    time.sleep(5)
    gf.log_today()

带有函数的支持文件 globalfunctions.py

import time
from datetime import datetime

def get_today():
    return time.time(), datetime.today()

def log_today(additional=""):
    curtime, today = get_today()

    datefile = open(additional+"date.txt", "w")
    datefile.write(str(today))
    datefile.close()

    timefile = open(additional+"timelog.txt", "w")
    timefile.write(str(curtime))
    timefile.close()

def get_log(additional=""):
    datefile = open(additional+"date.txt", "r")
    datestring = datefile.readline()

    timefile = open(additional+"timelog.txt", "r")
    timenumber = float(timefile.readline())

    return datestring, timenumber

def report_data(filename, text):
    curtime, today = get_today()
    outfile = open(filename, "a+")
    outfile.write(str(today) + " | " + text + "\n")
    outfile.close()

我尝试按照以下说明进行操作此主题但它似乎不起作用。我创建了一个 .service，内容如下：

[Unit]
Description=Python Internet Watcher

[Service]
Type=simple
WorkingDirectory=/home/connor/Documents/Pycharm
ExecStart=./internettracker.py


[Install]
WantedBy=multi-user.target

该文件已被移至 /lib/systemd/system/ ，到目前为止，我没有看到启动时运行任何内容。

我找到了解决问题的方法。我发现您可以为项目激活虚拟环境，然后在虚拟环境中启动程序。

在项目中，可以通过 [project_path]/venv/bin/python 激活 venv

以下是解决方案的变更：

[Unit]
Description=Python Internet Watcher
After=network-online.target

[Service]
WorkingDirectory=/home/connor/Documents/Pycharm
ExecStart=/home/connor/Documents/Pycharm/venv/bin/python internettracker.py start
Restart=always
RestartSec=15s
KillMode=process
TimeoutSec=infinity
User=connor
Group=connor

[Install]
WantedBy=multi-user.target

命令行 python
