背景
云平台https的域名服务器如果超过上百条,如果都分布在不同的服务器或者负载均衡上,如果即将过期, 做完替换SSL证书动作后,如何批量检查域名的SSL证书是否替换网站,可通过如下脚本实现。

Python脚本
保存domain-ssl-check.py文件内容如下:
#!/usr/bin/env python3 import ssl, socket import requests from dateutil import parser import pytz requests.packages.urllib3.disable_warnings() try: _create_unverified_https_context = ssl._create_unverified_context except AttributeError: # Legacy Python that doesn't verify HTTPS certificates by default pass else: # Handle target environment that doesn't support HTTPS verification ssl._create_default_https_context = _create_unverified_https_context def get_domain_content(domain): requests.packages.urllib3.disable_warnings() url = 'https://' + domain response = requests.get(url, verify=False).headers print(response) def get_my_domain(mydomain): try: socket.setdefaulttimeout(5) my_addr = socket.getaddrinfo(mydomain, None) c = ssl.create_default_context() s = c.wrap_socket(socket.socket(), server_hostname=mydomain) s.connect((mydomain, 443)) my_cert = s.getpeercert() get_my_cert_dated(mydomain, my_cert, my_addr) except ssl.CertificateError and socket.gaierror as e: pass def get_my_cert_dated(domain, certs, my_addr): cert_beginning_time = parser.parse(certs['notBefore']).astimezone(pytz.utc) cert_end_time = parser.parse(certs['notAfter']).astimezone(pytz.utc) print('域名:(%s) 证书失效时间: %s' % (domain, cert_end_time)) def read_domain_files(): with open('./domain.txt', 'r', encoding="utf-8") as file: for domain in file: try: get_my_domain(domain.strip()) except Exception as e: print('域名: (%s)-%s' %(domain.strip(), e)) if __name__ == "__main__": read_domain_files()
使用方法
准备domain.txt一个域名一行,可从DNS导出记录
cat > domain.txt << EOF linuxeye.com www.linuxeye.com oneinstack.com www.linuxeye.com EOF
执行:
python3 domain-ssl-check.py
