问题
I am trying to enable web services on my AWS elastic beanstalk LAMP project.
I just want to set up an auditing system. My requirements are fairly simple:
- Websocket connection
- Save incoming (JSON) messages to my mySQL db
In this regard, I asked this question yesterday: How can I set up Web Sockets on AWS and log incoming messages to s3 (elastic beanstalk project) mysql db
But having read the answer I got on this, and reading through the AWS API Gateway documentation I linked to on that question, I have come back to thinking that to do this, I need to use Ratchet. It doesn't seem like AWS API Gateway or AWS Lambda can fulfill my requirements (or?)
So in terms of installing Ratchet: Is it as simple as ssh-ing in, and using git ...?
- Connecting to my mySQL db: Are the environment constants that Amazon makes available on my PHP page (i.e. RDS_HOSTNAME, etc) going to be available? If not, can/should I add them manually to a config file? What about the mySQL connector (.so) plugin - does that need to be installed / configured?
- Do I need to open the port / do something with my loadbalancer to open the ws port? --edit-- I am looking over a number of other posts, and I see that I absolutely need to set this up with the load balancer, but there's plenty of stuff on this.
- Anything else I am not aware of?
--update--
Maybe I don't need Ratchet at all. I think for what I want I might be able to use an AWS Lambda to log incoming web socket messages. Would this work? If so, can you tell me how to go about setting this up?
