1,资料。官网:https://www.kafka-eagle.org/index.htmlGithub:https://github.com/smartloli/kafka-eagle/官方文档:https://docs.kafka-eagle.org/下载地址:http://download.kafka-eagle.org/2,部署。当我们把kafka集群部署完成之后,就可以部署Kafka Eagle监控系统了。github上的releases中事实上还是源码,而源码可能不容易编译成功,因此可以直接通过官网的下载地址下载作者已经提供的编译好的包进行部署。1,下载包。$ wget https://codeload.github.com/smartloli/kafka-eagle-bin/tar.gz/v1.3.32,解压包。[root@localhost opt]$ tar xf v1.3.3l[root@localhost opt]$ lskafka-eagle-bin-1.3.3 v1.3.3[root@localhost opt]$ cd kafka-eagle-bin-1.3.3/[root@localhost kafka-eagle-bin-1.3.3]$ lskafka-eagle-web-1.3.3-bin.tar.gz[root@localhost kafka-eagle-bin-1.3.3]$ tar xf kafka-eagle-web-1.3.3-bin.tar.gzl[root@localhost kafka-eagle-bin-1.3.3]$ lskafka-eagle-web-1.3.3 kafka-eagle-web-1.3.3-bin.tar.gz[root@localhost kafka-eagle-bin-1.3.3]$ mv kafka-eagle-web-1.3.3 /opt/kafka-eagle3,配置环境变量。cat >> /etc/profile <&l...

 Fiddler与其他抓包工具的区别 1、Firebug虽然可以抓包,但是对于分析http请求的详细信息,不够强大。模拟http请求的功能也不够,且firebug常常是需要“无刷新修改”,如果刷新了页面,所有的修改都不会保存; 2、Wireshark是通用的抓包工具,能获取HTTP,也能获取HTTPS,但是不能解密HTTPS,所以wireshark看不懂HTTPS中的内容,但如果是TCP、UDP协议可以用wireshark; 3、Httpwatch也是比较常用的http抓包工具,但是只支持IE和firefox浏览器(其他浏览器可能会有相应的插件);而Fiddler 是一个使用本地 127.0.0.1:8888 的 HTTP 代理,任何能够设置 HTTP 代理为 127.0.0.1:8888 的浏览器和应用程序都可以使用 Fiddler。Fiddler用来post,http请求工具软件。具体使用看附件。点击打开链接-Fiddler使用教程
