Error executing action `start` on resource 'service[nginx]'

nginx chef-infra chef-recipe cookbook

The log is quite clear I think:

STDERR: nginx: [emerg] invalid log level "pid" in /etc/nginx/nginx.conf:5

your nginx.conf.erb file as somewhere a problem as it writes a log_level = pid instead of info/error.

nginx chef-infra chef-recipe cookbook

This has not much to do with Chef. The important detail is:

nginx: [emerg] invalid log level "pid" in /etc/nginx/nginx.conf:5
