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86Please respect copyright.ＰＥＮＡＮＡSZUXvr3XGR
首先查看防火墙的状态：86Please respect copyright.ＰＥＮＡＮＡoBBm9bO9ux
# ufw status86Please respect copyright.ＰＥＮＡＮＡzezkW42Rc3
如果防火墙开启了，要开放80端口用于certbot验证86Please respect copyright.ＰＥＮＡＮＡvkRChZQKqU
# ufw allow 8086Please respect copyright.ＰＥＮＡＮＡCKkgherwuZ
# ufw allow 443
3 安装certbot: 86Please respect copyright.ＰＥＮＡＮＡNgOPgqFpJK
# apt install certbot
4. 生成证书：86Please respect copyright.ＰＥＮＡＮＡPJUX29DtPK
# certbot certonly86Please respect copyright.ＰＥＮＡＮＡfR0oY9B6An
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。86Please respect copyright.ＰＥＮＡＮＡKr6LKqx8jY
输入email: [email protected]86Please respect copyright.ＰＥＮＡＮＡMHzXBmigKO
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/86Please respect copyright.ＰＥＮＡＮＡ64DBjnfMAl
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86Please respect copyright.ＰＥＮＡＮＡ0LMyBtrG0K
# ps -aux | grep certbot86Please respect copyright.ＰＥＮＡＮＡMdDiqIN4P0
# kill 进程号（第二列的数字）
