如何配置 http -> https(免费证书)
下载安装 Certbot
具体步骤 https://certbot.eff.org/lets-encrypt/ubuntutrusty-nginx.html
配置nginx
先配置一个nginx(你得有服务器得有域名吧~) 注意替换(yourdomain.com)为自己的域名
vi /etc/nginx/conf.d/yourdomain.com.conf
张贴以下内容:
server {
listen 80;
server_name (www.)?yourdomain.com;
location ^~ /.well-known/acme-challenge/ {
default_type "text/plain";
root /usr/share/nginx/html;
}
location = /.well-known/acme-challenge/ {
return 404;
}
}
执行下 reload
nginx -s reload
证书生成
使用certbot 命令生成证书
certbot certonly --webroot -w /usr/share/nginx/html/ -d yourdomain
- -w 表示配置webroot路径 在上面已经配置为了 (/usr/share/nginx/html)
- -d 表示匹配的域名地址
certbot 生成证书的机制 会先通过http 发起请求像对应的域名 yourdomain/.well-known/acme-challenge/(这个也是为什么要配置nginx的原因)
修改nginx配置http强跳
http:80-> https:443
server {
...
return 301 https://$host$request_uri;
...
}
添加https配置 (ssl_certificate 证书地址在上一步生成的时候会在出现)
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name (www.)?yourdomain;
ssl_certificate /etc/letsencrypt/live/yourdomain/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/yourdomain/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/yourdomain/chain.pem;
# Load configuration files for the default server block.
location / {
proxy_pass http://localhost:port;
}
}
最后定期更新下证书,写一个定时脚本(毕竟免费的是会过期的)
/usr/bin/certbot renew >> /var/log/le-renew.log
