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127Please respect copyright.ＰＥＮＡＮＡP5TgmNSKTY
首先查看防火墙的状态：127Please respect copyright.ＰＥＮＡＮＡDXoiallUi5
# ufw status127Please respect copyright.ＰＥＮＡＮＡaR8feYIpi8
如果防火墙开启了，要开放80端口用于certbot验证127Please respect copyright.ＰＥＮＡＮＡIuz2rua2n4
# ufw allow 80127Please respect copyright.ＰＥＮＡＮＡReFu6tSI08
# ufw allow 443
3 安装certbot: 127Please respect copyright.ＰＥＮＡＮＡT5DaMWPR6A
# apt install certbot
4. 生成证书：127Please respect copyright.ＰＥＮＡＮＡrYe3fwmNWR
# certbot certonly127Please respect copyright.ＰＥＮＡＮＡpNuKt6HNot
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。127Please respect copyright.ＰＥＮＡＮＡeLbih8ZyIO
输入email: [email protected]127Please respect copyright.ＰＥＮＡＮＡMAoojFtBfB
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/127Please respect copyright.ＰＥＮＡＮＡOnCES2Uh4o
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127Please respect copyright.ＰＥＮＡＮＡ9bDC5qf2B8
# ps -aux | grep certbot127Please respect copyright.ＰＥＮＡＮＡqoKh0lulEw
# kill 进程号（第二列的数字）
