CentoS 8 安装
安装 Enable EPEL
官网地址：https://certbot.eff.org/
# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
# ARCH=$( /bin/arch )
# subscription-manager repos --enable "codeready-builder-for-rhel-8-${ARCH}-rpms"
# dnf config-manager --set-enabled PowerTools
安装 Certbot
dnf install certbot python3-certbot-nginx
运行 Certbot，并且自动配置证书
certbot --nginx
运行后效果如下图所示：
只需要获取证书，然后自己安装
certbot certonly --nginx
自动续签
这个证书只有三个月有效期，所有要自动续签，自动续签也很简单，添加定时任务即可
echo "0 0,12 * * * root python3 -c 'import random; import time; time.sleep(random.random() * 3600)' && certbot renew -q" | sudo tee -a /etc/crontab > /dev/null
CentoS 7 安装
安装 Enable EPEL
# 启用软件源
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum-config-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" --enable "rhel-ha-for-rhel-*-server-rpms"
# 安装 Certbot for Nginx
yum install certbot python2-certbot-nginx
运行 Certbot，并且自动配置证书，到这里就 GG 了，哈哈哈
certbot --nginx
因为年代久远的问题，Python 包很多不可用了，最好是卸载后重新安装最新的，不介绍
备用办法：采用脚本安装
-
获取安装脚本
wget https://dl.eff.org/certbot-auto -
赋予可执行权限
sudo chmod a+x ./certbot-auto -
运行脚本
./certbot-auto
运行后如下所示： 会自动将 http 重定向到 HTTPS ，如果不想，自己取消即可

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/dev-test.shuxiaoyuan.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/dev-test.shuxiaoyuan.com/privkey.pem
Your cert will expire on 2020-10-19. To obtain a new or tweaked
version of this certificate in the future, simply run certbot-auto
again with the "certonly" option. To non-interactively renew *all*
of your certificates, run "certbot-auto 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.
