Use SSH to Create an HTTP Proxy

All you need is virtual private server (VPS). Use the following command to open up the port 1080 on your local machine as a SOCKS proxy so all your HTTP traffic can be specified to go through the SSH tunnel and out remote_ssh_server on the other end.

$ ssh -D 1080 -f -C -q -N -p 22 user@server-ip

Use the SOCKS proxy in chrome

A+ SSL Test Nginx configuration

Generate your own key for DHE ciphers (ssl_dhparam)

$ sudo openssl dhparam -out /etc/ssl/dhparam.pem 2048

Trusted certificate (ssl_trusted_certificate)

Point to a trusted certificate chain file. This must contain the intermediate & root certificates (in that order from top to bottom). See exemple_full_chain.pem

Get the root and intermediate certificates from where you buyed the certificates. For me it was:

How to extract certificate information (including private key) from pfx file

Use openssl to extract private key. After executing the following line. you will need to enter the password used when the pfx file was created.

openssl pkcs12 -in file_name.pfx -out certificate.cer -nodes

When converting a PFX file to PEM format, OpenSSL will put all the certificates and the private key into a single file. You will need to open the file in a text editor and copy each certificate and private key (including the BEGIN/END statments) to its own individual text file and save them as certificate.cer, CACert.cer, and privateKey.key respectively.

Configure Nginx Reverse Proxy as failover

In this exemple of configuration, if the first server fail (proxy_connect_timeout) one time (max_fails), the second server will be used for 60s (fail_timeout).

The SSL certificate need to be configure on the ReverseProxy server AND the proxyied servers. You can use the same certificate and configurations on all servers.

To test the configuration you can change your host file to simulate the correct domain name.

Use the following tool to configure SSL with optimal configuration.
