# 脚本名称: create_new_domain_cert.sh
|
||
# 功能: 为新域名自动创建 Let's Encrypt SSL 证书
|
||
# 作者: Assistant
|
||
# 日期: 2026-03-22
|
||
# 用法:
|
||
# sudo ./create_new_domain_cert.sh
|
||
#
|
||
# 交互式输入：
|
||
# - 域名 (例如: example.com)
|
||
# - 后端服务端口 (例如: 3000)
|
||
# - 证书存放目录 (例如: /etc/ssl/certs/example.com)
|
||
#
|
||
# 前提条件:
|
||
# - 需要 root 权限运行
|
||
# - 需要安装 nginx
|
||
# - 需要开放 80 和 443 端口
|
||
#
|
||
# sudo chmod +x create_new_domain_cert.sh
