# 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?
|
|
|
|
在 `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`
