反向代理

反向代理(Reverse Proxy)方式是指以代理服务器来接受 internet 上的连接请求，然后将请求转发给内部网络上的服务器，并将从服务器上得到的结果返回给 internet 上请求连接的客户端，此时代理服务器对外就表现为一个反向代理服务器.

cd /usr/local/nginx/conf
vim nginx.conf


server {
    #侦听的80端口
    listen       80;
    server_name  localhost;

    location / {

        proxy_pass   http://127.0.0.1:81;    #在这里设置一个代理
        #以下是一些反向代理的配置可删除
        proxy_redirect             off;
        #后端的Web服务器可以通过X-Forwarded-For获取用户真实IP
        proxy_set_header           Host $host;
        proxy_set_header           X-Real-IP $remote_addr;
        proxy_set_header           X-Forwarded-For $proxy_add_x_forwarded_for;
        client_max_body_size       10m; #允许客户端请求的最大单文件字节数
        client_body_buffer_size    128k; #缓冲区代理缓冲用户端请求的最大字节数
        proxy_connect_timeout      300; #nginx跟后端服务器连接超时时间(代理连接超时)
        proxy_send_timeout         300; #后端服务器数据回传时间(代理发送超时)
        proxy_read_timeout         300; #连接成功后，后端服务器响应时间(代理接收超时)
        proxy_buffer_size          4k; #设置代理服务器(nginx)保存用户头信息的缓冲区大小
        proxy_buffers              4 32k; #proxy_buffers缓冲区，网页平均在32k以下的话，这样设置
        proxy_busy_buffers_size    64k; #高负荷下缓冲大小(proxy_buffers*2)
        proxy_temp_file_write_size 64k; #设定缓存文件夹大小，大于这个值，将从upstream服务器传
    }
}

添加https

openssl req -new -x509 -nodes -days 365 -newkey rsa:1024  -out httpd.crt -keyout httpd.key    # 生成自签名证书,信息不要瞎填,Common Name一定要输你的网址

mv httpd.crt /etc/nginx
mv httpd.key /etc/nginx

vim /etc/nginx/conf.d/test.com.conf

server {
        listen       443 ssl http2;
        server_name  www.test.com test.com;
        root         /usr/share/nginx/test.com;
        index index.html;

        ssl_certificate "/etc/nginx/httpd.crt";
        ssl_certificate_key "/etc/nginx/httpd.key";
        location / {
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

systemctl restart nginx

获取 RTMP 模块

add-apt-repository universe
apt install libnginx-mod-rtmp

vim /etc/nginx/nginx.conf

++ rtmp {
++    server {
++     listen 1935;
++     chunk_size 4096;
++     application live {
++       live on;
++       record off;
++     }
++   }
++ }

systemctl restart nginx

obs 上设置

然后开始推流即可

隐藏 Nginx 版本号

编辑 nginx.conf

在 http{} 段中加入 server_tokens off;

413 Request Entity Too Large

nginx 默认上传文件的大小是 1M，可 nginx 的设置中修改

编辑 nginx.conf

在 http{} 段中加入 client_max_body_size 20m

将允许最大上传的大小设为 20m
