502错误的网关错误与运行uwsgi和nginx的python应用程序（centos）

Question

Seen this question asked but all seemed to be Ubuntu and the solutions didn't quite work for me on Centos. I have a flask app trying to run from uwsgi and am getting

2017/07/26 17:44:24 [crit] 22785#0: *7 connect() to unix:/home/myname/perm_check/index.sock failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: 127.0.0.1, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/home/myname/perm_check/index.sock:", host: "127.0.0.1"

(it runs fine from virtualenv to localhost:500 or localhost:8000 with wsgi as per this https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-uwsgi-and-nginx-on-centos-7 tutorial.

Here are my files: index.ini

module = wsgi

master = true
processes = 5

socket = index.sock
chmod-socket = 664
vacuum = true

die-on-term = true

index.py

app = Flask(__name__)

    app.run(host='0.0.0.0')

}

I know I'm missing something simple somewhere but I can't for the life of me figure it out. Permissions for everything is myname:myname and I'm trying to run the uwsgi service from 127.0.0.1.
