- Instead making a request to the APISIX host and port where the filter
matching succeeds:
+ 而给 APISIX 的主机和端口发出请求，过滤器匹配成功。
Review comment:
I see, here seems a little unclear.
Here we can express: the following request matches stream route 1, so it can
be proxied to mysql normally.

例子中 APISIX 会把服务器地址为 `127.0.0.1`, 端口为 `2000` 代理到上游地址 `127.0.0.1:1995`。
+让我们再举一个实际场景的例子：
+
+1. 将此配置放在 `config.yaml` 中
+
+ ```yaml
+ apisix:
+ stream_proxy: # TCP/UDP proxy
+ tcp: # TCP proxy address list
+ - 9100 # by default uses 0.0.0.0
+ - "127.0.0.10:9101"
+ ```
+
+2. 现在运行一个 mysql docker 容器并将端口 3306 暴露给主机
+
+ ```shell
+ $ docker run --name mysql -e MYSQL_ROOT_PASSWORD=toor -p 3306:3306 -d mysql
+ # check it using a mysql client that it works
+ $ mysql --host=127.0.0.1 --port=3306 -u root -p
+ Enter password:
+ Welcome to the MySQL monitor. Commands end with ; or \g.
+ Your MySQL connection id is 25
+ ...
+ mysql>
+ ```
+
+3. 现在我们将创建一个带有服务器过滤的 stream 路由：
+
+ ```shell
+ curl http://127.0.0.1:9080/apisix/admin/stream_routes/1 -H 'X-API-KEY:
edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
+ {
+ "server_addr": "127.0.0.10",
+ "server_port": 9101,
+ "upstream": {
+ "nodes": {
+ "127.0.0.1:3306": 1
+ },
+ "type": "roundrobin"
+ }
+ }'
+ ```
+
+ 每当 APISIX 服务器 `127.0.0.10` 和端口 `9101` 收到连接时，它只会将请求转发到 mysql 上游。让我们测试一下：
+
+4. 向 `9100` 发出请求（在 config.yaml 中启用 stream 代理端口），过滤器匹配失败。
+
+ ```shell
+ $ mysql --host=127.0.0.1 --port=9100 -u root -p
+ Enter password:
+ ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial
communication packet', system error: 2

Is there any special output in the apisix logs at the time of this error?
