[Plugin](plugin.md) 只能绑定在 [Service](service.md) 或者 [Route](route.md) 上，如果我们需要一个能作用于所有请求的 [Plugin](plugin.md) 该怎么办呢？
这时候我们可以使用 `GlobalRule` 来注册一个全局的 [Plugin](plugin.md):

```shell
curl -X PUT \
  https://{apisix_listen_address}/apisix/admin/global_rules/1 \
  -H 'Content-Type: application/json' \
  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' \
  -d '{
        "plugins": {
            "limit-count": {
                "time_window": 60,
                "policy": "local",
                "count": 2,
                "key": "remote_addr",
                "rejected_code": 503
            }
        }
    }'
```

如上所注册的 `limit-count` 插件将会作用于所有的请求。

我们可以通过以下接口查看所有的 `GlobalRule`:

```shell
curl https://{apisix_listen_address}/apisix/admin/global_rules -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1'
```
