Have you read the documentation on using cosockets in the init phases?https://github.com/openresty/lua-nginx-module#cosockets-not-available-everywhere

In short, if you really do intend to connect to Redis when Nginx starts, use the ngx.timer API to create a "light thread" in your init phase, as this light thread will be able use cosockets.
