Nginx 开启 ssl 以支持 HTTPS

$!IMPORTANT$
在下文中，将采用如下定义。

HTTP端口： 80

HTTPS端口： 443

服务地址： www.0ll1.com，也可以是 IP

1 生成本地证书

生成一个 RSA 私钥：server.key
nginx 复制代码
```
openssl genrsa -out server.key 2048
```

生成一个自签名的 X.509 证书：server.crt

nginx 复制代码

openssl req -new -x509 -days 8760 -key server.key -out server.crt -subj "/C=CN/O=Institute of Information Engineering, CAS/CN=www.0ll1.com"

2 开启 ssl 以支持 HTTPS

nginx 复制代码

server {
    listen 443 ssl;
    server_name www.0ll1.com;
    ssl_certificate /usr/local/nginx/cert/server.crt;
    ssl_certificate_key /usr/local/nginx/cert/server.key;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH;
    ssl_prefer_server_ciphers on;
}

3 将 https 的请求转发给 http

nginx 复制代码

server {
    location / {
        proxy_set_header Host $host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 60;
        proxy_read_timeout 600;
        proxy_send_timeout 600;
        proxy_pass http://www.0ll1.com:80;
    }
}

$!NOTE$
只需要将 proxy_pass 修改为 http 服务的 url 即可。

最终的 nginx.conf 如下

nginx 复制代码

server {
    listen 443 ssl;
    server_name www.0ll1.com;
    ssl_certificate /usr/local/nginx/cert/server.crt;
    ssl_certificate_key /usr/local/nginx/cert/server.key;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH;
    ssl_prefer_server_ciphers on;

    location / {
        proxy_set_header Host $host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 60;
        proxy_read_timeout 600;
        proxy_send_timeout 600;
        proxy_pass http://www.0ll1.com:80;
    }
}
