ssl证书续期

ssl证书续期

小卖铺上新啦!ChatGPT账号大甩卖! 一键直达

免费证书都是3个月到期,需要手动续期,所以写了一个监控加自动续期的服务,有兴趣的可以试一试

import ssl
import socket
import requests
import schedule
import time
from datetime import datetime
import subprocess

# Telegram Bot设置
TELEGRAM_TOKEN = ''
TELEGRAM_CHAT_ID = ''

# 储存域名列表
domains = [
    'tool.wangwangit.com'
]

def send_telegram_message(message):
    url = f"https://api.telegram.org/bot{TELEGRAM_TOKEN}/sendMessage"
    data = {
        "chat_id": TELEGRAM_CHAT_ID,
        "text": message
    }
    requests.post(url, data=data)

def get_ssl_expiry_date_from_shell(hostname, port=443):
    cmd = f"echo | openssl s_client -servername {hostname} -connect \"{hostname}:{port}\" 2>/dev/null | openssl x509 -noout -dates"
    process = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    out, err = process.communicate()
    if process.returncode != 0:
        return f"Error executing command: {err.decode().strip()}"
    return out.decode().strip()

def renew_ssl(domain):
    subprocess.run(['nginx', '-s', 'stop'])
    time.sleep(10)  # 等待nginx停止
    subprocess.run(['acme.sh', '--issue', '-d', domain, '--standalone', '--force'])
    time.sleep(30)  # 等待证书申请
    subprocess.run(['nginx'])
    subprocess.run(['nginx', '-s', 'reload'])
    time.sleep(10)  # 等待nginx重启

def format_expiry_date(date_str):
    try:
        # 提取日期字符串并转换为datetime对象
        expiry_date = datetime.strptime(date_str, '%b %d %H:%M:%S %Y %Z')
        # 返回格式化的日期字符串
        return expiry_date.strftime('%Y-%m-%d %H:%M:%S')
    except ValueError:
        return date_str  # 返回原始字符串,如果格式不匹配

def check_all_domains():
    messages = []
    for domain in domains:
        ssl_dates = get_ssl_expiry_date_from_shell(domain)
        expiry_date_line = ssl_dates.split('\n')[1] if 'notAfter' in ssl_dates else ssl_dates
        expiry_date = expiry_date_line.split('=')[1] if 'notAfter' in expiry_date_line else "Unknown"
        formatted_date = format_expiry_date(expiry_date)
        if "Error" in ssl_dates or "Unknown" in expiry_date:
            message = f"{domain} SSL证书检查失败:{formatted_date},请手动检查。"
            messages.append(message)
        else:
            message = f"{domain} SSL证书状态正常,有效期至 {formatted_date}。"
            messages.append(message)

    # 将所有消息发送到Telegram
    send_telegram_message("\n".join(messages))

# 设置定时任务
schedule.every().day.at("10:00").do(check_all_domains)

# 运行定时任务
while True:
    schedule.run_pending()
    time.sleep(1)

运行情况如下:
