+### 启动失败，报
+```
+[1] bootstrap checks failed
+[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
+```
+修改配置文件elasticsearch.yml文件，至少一项配置放开即可discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes，这里修改cluster.initial_master_nodes: : ["node-1"]
+
+### 往es中写数据,报
+```
+curl -XPUT 127.0.0.1:9200/item/es/1?pretty -d '{"name": "wang", "age": 25}'
+{
+  "error" : "Content-Type header [application/x-www-form-urlencoded] is not supported",
+  "status" : 406
+}
+```
+
+写入数据时，加上-H 'content-Type:application/json' 即可，如下
+```
+curl -XPUT 127.0.0.1:9200/item/es/1?pretty -H 'content-Type:application/json' -d '{"name": "wang", "age": 25}'
