Https

配置流程

本方法配置 https 用的是 Let’s Encrypt ，系统为 centOS

1. 防火墙打开 80 和 443 端口

firewall-cmd --permanent --add-port=80/tcp
firewall-cmd --permanent --add-port=443/tcp
firewall-cmd --reload

2. 安装 certbot 工具

yum install -y epel-release
yum install -y certbot

3. 申请证书

申请成功后，证书会保存在 /etc/letsencrypt/live/j710328466.github.io/ 下面：

certbot certonly --webroot -w [Web站点目录] -d [站点域名] -m [联系人email地址] --agree-tos

e.g: certbot certonly --webroot -w /usr/local/nginx/html -d j710328466.github.io -m jzx710328466@gmail.com --agree-tos

4. 创建自动更新证书脚本

因为 Let's Encrypt 的证书有效时长是 90 天，如果想要省去手动去更新脚本的操作，那这个时候就需要给个脚本来实现自动化

//更新证书
certbot renew --dry-run
 
//如果不需要返回的信息，可以用静默方式
certbot renew --quiet

// 编辑开始写入自动化脚本
crontab -e

// 把这段写入脚本的最后一行，意思是每月的一号 5点会自动更新签名并且重新启动nginx
00 05 01 * * /usr/bin/certbot renew --quiet && /bin/systemctl restart nginx

5. 配置 nginx

修改默认的 server

server {
  listen       80;
  server_name  j710328466.github.io;
  rewrite ^ https://$server_name$request_uri? permanent;
}

修改 https 的 server

# HTTPS server
#
server {
    listen       443 ssl;
    server_name  j710328466.github.io;

    ssl_certificate      /etc/letsencrypt/live/j710328466.github.io/fullchain.pem;
    ssl_certificate_key  /etc/letsencrypt/live/j710328466.github.io/privkey.pem;

    ssl_session_cache    shared:SSL:1m;
    ssl_session_timeout  5m;

    ssl_dhparam /etc/ssl/private/dhparam.pem;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
