https 自动续签

我的系统是 Alibaba Cloud Linux 3​​ 
sudo dnf install epel-release --allowerasing -y

下图显示表示安装成功!

把certbot变成全局命令

sudo ln -s /usr/bin/certbot /usr/local/bin/certbot
# 测试是否安装成功
certbot --version

运行certbot

# 但在运行 sudo certbot --nginx 时提示 ​​nginx 插件未安装​​
sudo yum install certbot-nginx
sudo certbot --nginx

nginx 配置

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;


include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
