nginx local proxy

I wanted just a simple nginx setup to forward to a local app.  Here's the result:


http {
...

    server {
      server_name  52.62.72.255;
      #access_log   /var/log/nginx/histories.log;
      location / {
        proxy_pass      http://127.0.0.1:3000;
      }
    }


For some reason it was hard to find this info!  I had to pull it from one of my other servers.  But one good example is this reference: http://wiki.nginx.org/FullExample

Unable to SSH to new AWS servers, until: route table

Symptoms: I've had an AWS account for years, and I went back and created some instances this past week but then I couldn't access them (via SSH: "Operation timed out"). One oddity was that my old instances had no VPC ID, but every new instance had one (and the VPC was created if none existed).

Solution: I found this troubleshooting guide for connecting, and I followed the step on route tables and added a route with a destination of 0.0.0.0/0 and target of igw... (which is auto-filled with my internet gateway ID).

I've never had to do this before.  Hopefully I'll remember!

PermanentRedirect when accessing AWS S3 bucket

When running this on the command-line:

aws s3 ls s3://my-bucket/

I kept getting this error:

A client error (PermanentRedirect) occurred when calling the ListObjects operation: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

The problem was that my region wasn't set. I did this to fix it:

export AWS_DEFAULT_REGION=us-west-2

This is a pretty stupid situation: when using the web console, the S3 service says that there's no need to choose a region, and it won't even let you select one. But obviously it's very important for configurations. Dumb.
