# Stream Proxy
|
|
|
|
TCP is the protocol for many popular applications and services, such as LDAP, MySQL, and RTMP. UDP (User Datagram Protocol) is the protocol for many popular non-transactional applications, such as DNS, syslog, and RADIUS.
|
|
|
|
APISIX can dynamic load balancing TCP/UDP proxy. In Nginx world, we call TCP/UDP proxy to stream proxy, we followed this statement.
|
|
|
|
## How to enable Stream proxy?
|
|
|
|
Setting the `stream_proxy` option in `conf/config.yaml`, specify a list of addresses that require dynamic proxy.
|
|
By default, no any stream proxy is enabled.
|
|
|
|
```yaml
|
|
apisix:
|
|
stream_proxy: # TCP/UDP proxy
|
|
tcp: # TCP proxy address list
|
|
- 9100
|
|
- "127.0.0.1:9101"
|
|
udp: # UDP proxy address list
|
|
- 9200
|
|
- "127.0.0.1:9211"
|
|
```
|
|
|
|
## How to set route?
|
|
|
|
Here is a mini example:
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/stream_routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"remote_addr": "127.0.0.1",
|
|
"upstream": {
|
|
"nodes": {
|
|
"127.0.0.1:1995": 1
|
|
},
|
|
"type": "roundrobin"
|
|
}
|
|
}'
|
|
```
|
|
|
|
It means APISIX will proxy the request to `127.0.0.1:1995` which the client remote address is `127.0.0.1`.
|
|
|
|
For more use cases, please take a look at [test case](../t/stream-node/sanity.t).
|
|
|
|
## More Limit Options
|
|
|
|
And we can add more limit options to match a route, here is an example:
|
|
|
|
```shell
|
|
curl http://127.0.0.1:9080/apisix/admin/stream_routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
|
{
|
|
"server_addr": "127.0.0.1",
|
|
"server_port": 2000,
|
|
"upstream": {
|
|
"nodes": {
|
|
"127.0.0.1:1995": 1
|
|
},
|
|
"type": "roundrobin"
|
|
}
|
|
}'
|
|
```
|
|
|
|
It means APISIX will proxy the request to `127.0.0.1:1995` which the server remote address is `127.0.0.1` and the server port is equal `2000`.
