Kibana日志分析系统建设指南<\/h1>

一、Kibana简介<\/h2>
Kibana是一个与Elasticsearch协同工作的开源分析和可视化平台，主要用于：<\/p>
查询、查看并与Elasticsearch索引数据进行交互<\/li>
执行高级数据分析<\/li>
以图表、表格和地图形式可视化数据<\/li>
创建实时更新的仪表盘<\/li> <\/ul>
版本演进：<\/p>
Elasticsearch 5版本之前：需安装Kibana后添加各种功能插件(如marvel、hand等)<\/li>
Elasticsearch 5版本之后：推荐安装x-pack扩展包即可<\/li> <\/ul>
二、Kibana安装<\/h2>

1. Linux系统安装(deb\/rpm)<\/h3>
curl -L -O https:\/\/artifacts.elastic.co\/downloads\/kibana\/kibana-6.3.1-linux-x86_64.tar.gz
<\/span><\/span>tar xzvf kibana-6.3.1-linux-x86_64.tar.gz
<\/span><\/span>cd kibana-6.3.1-linux-x86_64\/
<\/span><\/span>.\/bin\/kibana
<\/span><\/span><\/code><\/pre>2. Mac OS X安装<\/h3>
curl -L -O https:\/\/artifacts.elastic.co\/downloads\/kibana\/kibana-6.3.1-darwin-x86_64.tar.gz
<\/span><\/span>tar xzvf kibana-6.3.1-darwin-x86_64.tar.gz
<\/span><\/span>cd kibana-6.3.1-darwin-x86_64\/
<\/span><\/span>.\/bin\/kibana
<\/span><\/span><\/code><\/pre>3. Windows安装<\/h3>

从Kibana下载页面下载Windows zip文件<\/li>
解压到指定目录(如C:\Program Files)<\/li>
以管理员身份打开命令提示符并切换到安装目录：
cd<\/span> C:\Program Files\kibana-6.3.1-windows
<\/span><\/span><\/code><\/pre><\/li>
启动Kibana：
bin\kibana.bat
<\/span><\/span><\/code><\/pre><\/li>
<\/ol>
三、运行测试<\/h2>
启动后，在浏览器访问：<\/p>
http:\/\/localhost:5601
<\/code><\/pre>
四、检查Kibana状态<\/h2>
访问状态页面查看服务器资源使用情况和已安装插件：<\/p>
http:\/\/localhost:5601\/status
<\/code><\/pre>
五、配置外部访问<\/h2>
默认配置(127.0.0.1)仅允许本地访问，修改kibana.yml<\/code>文件实现外部访问：<\/p>

找到配置文件(通常位于\/etc\/kibana<\/code>或使用find \/ -name kibana.yml<\/code>查找)<\/li>
修改以下参数：
server.port<\/span>: 5601<\/span>  # Kibana运行端口<\/span>
<\/span><\/span>server.host<\/span>: "服务器IP"<\/span>  # 改为服务器实际IP<\/span>
<\/span><\/span>elasticsearch.url<\/span>: "http:\/\/elasticsearch服务器IP:9200"<\/span>  # Elasticsearch连接地址<\/span>
<\/span><\/span><\/code><\/pre><\/li>
重启Kibana服务<\/li>
<\/ol>
六、Kibana常用配置与功能<\/h2>
