# 验证集群是否正常

### 查看节点

```
curl es:9200/_cat/nodes
```

### 查看集群状态

```
curl es:9200/_cluster/health?pretty
```

### 查看安装的查看

```
curl es:9200/_cat/plugins
```

### 测试分词器

```
curl -XPOST -H 'Content-Type: application/json' es:9200/_analyze --data '{"text":"朋辈是一家人工智能公司","analyzer":"ik_smart"}'
```

### 写入数据

```
curl -XPOST -H 'Content-Type: application/json' es:9200/df/df/1 --data '{"a":1}'
curl -XGET es:9200/df/df/1
```
