https(全称:Hyper Text Transfer Protocol over Secure Socket Layer),是以安全为目标的 http 通道,简单讲是 http 的安全版。即 http 下加入 SSL 层,https 的安全基础是 SSL,因此加密的详细内容就需要 SSL。
LAMP 新增对 Let’s Encrypt 的支持,自动签发免费的证书,并添加自动任务到 crond,定期运行自动更新证书。
安装完 LAMP 后,lamp 命令就可以使用了,用法如下。

Usage: lamp [ add | del | list ]
add     Create new Apache Virtual Host
del     Delete Apache Virtual Host
list    List all of Apache Virtual Host

下面为使用 lamp 命令增加 SSL 证书支持的详细使用教程。


注意:在新增虚拟主机之前,请务必确保域名已经解析到该服务器(VPS)的 IP 上,否则 Let’s Encrypt 验证无法通过。

Cleaning up challenges
 - Congratulations! Your certificate and chain have been saved at:
   Your key file has been saved at:
   Your cert will expire on 2018-02-02. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot
   again. To non-interactively renew *all* of your certificates, run
   "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:
