kafka-manager安装及异常退出后无法启动解决办法

#这边我下载好的kafka-manager为zip包，上传至服务器/root下:

#解压kafka-manager.zip，没有unzip工具的直接yum安装一个

yum install unzip -y

unzip kafka-manager.zip

vim /root/kafka-manager-1.3.3.7/conf/application.conf

#启动kafka-manager 

nohup ./../bin/kafka-manager -Dhttp.port=9001 -Dconfig.file=./application.conf >/dev/null 2>&1 & 

#启动成功后jps查看时候有ProdServerStart进程，如果有确认已经启动成功；

#在浏览器直接出入localhost:9001进入管理页面进行配置应用即可；

#如果访问之后不能创建cluster，将浏览器模式更改为兼容或极速模式；

#kafka-manager在异常退出后无法启动？

#解决办法：删除安装目录下RUNNING_PID文件，重启即可；
