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76Please respect copyright.ＰＥＮＡＮＡXbLJORWBGa
首先查看防火墙的状态：76Please respect copyright.ＰＥＮＡＮＡh30lWgtPqg
# ufw status76Please respect copyright.ＰＥＮＡＮＡ2PSOowSlLP
如果防火墙开启了，要开放80端口用于certbot验证76Please respect copyright.ＰＥＮＡＮＡW0IFzuNKML
# ufw allow 8076Please respect copyright.ＰＥＮＡＮＡB98mVwQRXy
# ufw allow 443
3 安装certbot: 76Please respect copyright.ＰＥＮＡＮＡNDq3kpnv2K
# apt install certbot
4. 生成证书：76Please respect copyright.ＰＥＮＡＮＡaptTIMCGrO
# certbot certonly76Please respect copyright.ＰＥＮＡＮＡ6FKOH5Ud4W
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。76Please respect copyright.ＰＥＮＡＮＡmi66DuknCF
输入email: [email protected]76Please respect copyright.ＰＥＮＡＮＡrVs50I2ksf
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/76Please respect copyright.ＰＥＮＡＮＡ5t3JaVdClQ
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76Please respect copyright.ＰＥＮＡＮＡvCzaPtWFW0
# ps -aux | grep certbot76Please respect copyright.ＰＥＮＡＮＡqdaki1xmbl
# kill 进程号（第二列的数字）
