"ssl_preread" is not working in NGINX

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

Perhaps this is a late answer. I had the following issue when installing nginx 1.14 from CentOS 8.3 repo.

The error was: MisconfigurationError('Error while running nginx -c /etc/nginx/nginx.conf -t.\n\nnginx: [emerg] unknown "ssl_preread_server_name" variable\nnginx: configuration file /etc/nginx/nginx.conf test failed\n',)
The nginx plugin is not working; there may be problems with your existing configuration.
The error was: MisconfigurationError('Error while running nginx -c /etc/nginx/nginx.conf -t.\n\nnginx: [emerg] unknown "ssl_preread_server_name" variable\nnginx: configuration file /etc/nginx/
nginx.conf test failed\n',)

I fixed it by upgrading the very latest nginx-1:1.20.0-1.el8.ngx.x86_64, following this URL

http://nginx.org/en/linux_packages.html#RHEL-CentOS

Maybe U need to update Nginx to lastest version. 1.10 I meet this error too, but 1.18 the config is OK.

  1. Compile with both modules

--with-stream

--with-stream_ssl_preread_module

  1. 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
