shuson

Puppet, from Puppet Labs

It is a configuration management tool that helps system administrators automate the provisioning, configuration, and management of a server infrastructure.

Chef

It is a systems and cloud infrastructure automation framework that makes it easy to deploy servers and applications to any physical, virtual, or cloud location, no matter the size of the infrastructure. Each organization is comprised of one (or more) workstations, a single server, and every node that will be configured and maintained by the chef-client. Cookbooks (and recipes) are used to tell the chef-client how each node in your organization should be configured. The chef-client (which is installed on every node) does the actual configuration.

var https = require('https');

https.get('https://www.douban.com/', function(res) {
  console.log("cert info: ", res.socket.getPeerCertificate());
}).on('error', function(e) {
  console.error(e);
});

//that's it, but no Official API shows socket has ''getPeerCertificate'' function

reason is in the mysql/connector/cursor.py file

see these lines:
  def _set_connection(self, connection):
        """Set the connection"""
