"ssl_preread" is not working in NGINX

Question

I am trying to implement "ssl_preread" in my nginx. My nginx is compiled with "--with-stream_ssl_preread_module" this module.

I mentioned "ssl_preread on;" in server directive of nginx.conf. But i am getting below error.

nginx: [emerg] "ssl_preread" directive is not allowed here in /opt/nginx/conf/nginx.conf:43

I am following below doc.

http://nginx.org/en/docs/stream/ngx_stream_ssl_preread_module.html

Answer 1

1. Compile with both modules

--with-stream

--with-stream_ssl_preread_module

2. Create a stream block outside http block

stream {
    upstream app {
        server IP1:Port;
      server IP2:Port;
    }

    map $ssl_preread_server_name $upstream {
        default app;
    }

    server {
        listen PORT;

        ssl_preread on;
        proxy_pass $upstream;
    }
}

This worked for me. Let me know if this works for you too
