明慈淨行記 - 第31章《Coding Art》第5篇 Ubuntu Linux 22 使用certbot生成ssl证书

1. 将需要生成SSL证书的域名解析到它對應的IP地址

2. 检查防火墙的设置331Please respect copyright.ＰＥＮＡＮＡ5Fxk0Y4uL7
首先查看防火墙的状态：331Please respect copyright.ＰＥＮＡＮＡu4ogdztMkh
# ufw status331Please respect copyright.ＰＥＮＡＮＡjDb0YJyWs3
如果防火墙开启了，要开放80端口用于certbot验证331Please respect copyright.ＰＥＮＡＮＡax2WlEUgyq
# ufw allow 80331Please respect copyright.ＰＥＮＡＮＡ3OaOzFQxWd
# ufw allow 443

3 安装certbot: 331Please respect copyright.ＰＥＮＡＮＡUktyfiMgyn
# apt install certbot

4. 生成证书：331Please respect copyright.ＰＥＮＡＮＡDg0Z8kRO3k
# certbot certonly331Please respect copyright.ＰＥＮＡＮＡksR0CesLJZ
选择authenticate时，如果服务上有apache或其它网站服务器在80端口运行，选择2使用已有的网站服务器验证；否则选1让certbot创建一个临时的网站来验证。331Please respect copyright.ＰＥＮＡＮＡ0zgkpJbE5C
输入email: [email protected]331Please respect copyright.ＰＥＮＡＮＡK5q5b4PDcG
域名：idealand.xyz

5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/331Please respect copyright.ＰＥＮＡＮＡex0ESgYNS6
fullchain.pem为公钥，privkey.pem为私钥

6. 如果运行certbot的过程中断线，再次运行前需要结束之前的进程331Please respect copyright.ＰＥＮＡＮＡkwQkGC5292
# ps -aux | grep certbot331Please respect copyright.ＰＥＮＡＮＡnc5oWeWkvx
# kill 进程号（第二列的数字）
