Upstream management =================== `nginx_upstreams`: List of dict. An upstream has few keys. See bellow. Note: Few params are unavailable on old Nginx version. But this role do _not_ put it if your version is too old! Upstream params --------------- - `name`: upstream name. Can be use in vhost with *proxy_pass http://upstream_name* - `params`: list of param (hash, zone...) - `servers`: each upstream MUST have at least 1 server Server params ------------- You must set a `path`. For example: *192.168.0.50:8080* or *unix:/tmp/my.sock*. All this params are optional. You should see [Nginx upstream doc](http://nginx.org/en/docs/http/ngx_http_upstream_module.html). - `weight` - `max_fails` - `fail_timeout` - `backup` - `down` - `route` - `slow`start`
