Port Reference
By default, APISIX exposes the following ports or reserved listening ports:
| Port | Protocol | Description |
|---|---|---|
9080 | HTTP | Listen for user requests. |
9443 | HTTPS | Listen for user requests with SSL enabled. |
9181 | PROXY | Listen for HTTP traffic with PROXY protocol when PROXY protocol is enabled. |
9182 | PROXY | Listen for HTTPS traffic with PROXY protocol when PROXY protocol is enabled. |
9090 | HTTP | Listen on loopback for requests to Control API when Control API is enabled. |
9100 | TCP | Listen for TCP traffic when transport layer (L4) proxy is enabled. |
9200 | UDP | Listen for UDP traffic when transport layer (L4) proxy is enabled. |
9180 | HTTP(S) | Listen for requests to Admin API. |
9091 | HTTP | Export metrics for Prometheus when the Prometheus export server is enabled. |
The redirect plugin does not open another HTTPS port. When http_to_https is enabled, the plugin redirects requests to a configured SSL listener, which uses port 9443 by default. Configure plugin_attr.redirect.https_port to override the redirect destination port.
To learn more about how to change the default ports, see configuration files.
