# Stream 代理
众多的闻名的应用和服务,像 LDAP、 MYSQL 和 RTMP ,选择 TCP 作为通信协议。 但是像 DNS、 syslog 和 RADIUS 这类非事务性的应用,他们选择了
UDP协议。
APISIX 可以对 TCP/UDP 协议进行代理并实现动态负载均衡。 在 nginx 世界,称 TCP/UDP 代理为 stream 代理,在 APISIX 这里我们也遵循了这个声明.
## 如何开启 Stream 代理?
2019-10-31 09:27:28 +08:00
`conf/config.yaml` 配置文件设置 `stream_proxy` 选项, 指定一组需要进行动态代理的IP地址。默认情况不开启stream代理。
```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
```
## 如何设置 route ?
简例如下:
```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"
}
}'
```

例子中 APISIX 对客户端IP为 `127.0.0.1` 的请求代理转发到上游主机 `127.0.0.1:1995`
更多用例,请参照 [test case](../t/stream-node/sanity.t).
## 更多限制选项
我们可以添加更多的选项来匹配 route ,例如
```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"
}
}'
```
例子中 APISIX 把上游地址 `127.0.0.1:1995` 代理成地址为 `127.0.0.1`, 端口为 `2000`
