### 安装 es-header插件 ###

源码地址：[传送门][Link 1]

1.下载源码后如果要运行es-header还需要下载node.js，因为我们下载的es-header是一个前端的源码如果需要使用就必须安装node.js

2.下载完成后就傻瓜式安装，一直next，安装完成后打开命令窗口，输入下面的命令验证是否安装成功

> node -v  
> npm -v

9.解决方案：切换到root用户到 es的config路径下修改 elasticsearch.yml 文件

> vi elasticsearch.yml

# ---------------------------------- Network -----------------------------------
    #
    # Set the bind address to a specific IP (IPv4 or IPv6):
    #
    network.host: 0.0.0.0
    #
    # Set a custom port for HTTP:
    #
    #http.port: 9200
    #
    # For more information, consult the network module documentation.
    
    http.cors.enabled: true  // 允许跨域访问
    http.cors.allow-origin: "*"  // 所有请求链接都能访问

10.配置完成后重启 es

> ps -ef | grep elasticsearch // 查看 es 运行的进程号  
> kill -9 <es的运行的进程号>  
> ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NTQ0NTg3OQ_size_16_color_FFFFFF_t_70_pic_center 4]

11.再次点击连接就能成功连接上了
