1.搭建

[root@bogon ~]# cd /usr/local
[root@bogon ~]# rz
[root@bogon ~]# tar -zxvf kafka-eagle-web-2.0.5-bin.tar.gz
[root@bogon ~]# ls 
kafka-eagle-web-2.0.5  kafka-eagle-web-2.0.5-bin.tar.gz
[root@bogon ~]# cd kafka-eagle-web-2.0.5
[root@bogon kafka-eagle-web-2.0.5]# ls 
bin  conf  db  font  kms  logs
[root@bogon kafka-eagle-web-2.0.5]#

• 为 Kafka-Eagle 配置环境变量

  [root@bogon efak-web-3.0.1]# vim /etc/profile
  //在文件末尾追加如下内容
  export KE_HOME=/usr/local/kafka-eagle/efak-web-3.0.1
  export PATH=$PATH:$KE_HOME/bin
  [root@bogon efak-web-3.0.1]# source /etc/profile
  

• 需要修改 Kafka-Eagle 内部的配置文件

  efak.zk.cluster.alias=cluster1
  cluster1.zk.list=192.168.137.200:2181,192.168.137.200:2182,192.168.137.200:2183
  ......
  efak.driver=com.mysql.cj.jdbc.Driver
  efak.url=jdbc:mysql://192.168.0.120:3306/ke?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
  efak.username=root
  efak.password=123456
  

• 创建数据库

创建上面配置文件中的数据库

• 启动

  [root@bogon conf]# cd ../bin
  [root@bogon bin]# ls -l
  total 24
  -rw-r--r--. 1 root root  1848 Sep 13  2021 ke.bat
  -rwxr-xr-x. 1 root root 11289 Dec 12  2021 ke.sh
  -rwxr-xr-x. 1 root root  4776 Dec 12  2021 worknode.sh
  [root@bogon bin]# ./ke.sh start
  ......
  * Welcome, Now you can visit 'http://10.0.2.4:8048'
  * Account:admin ,Password:123456
  ......
  [root@bogon bin]#
  

  如果无法访问，日志文件报错
  • The server time zone value '�й���׼ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specifc time zone value if you want to utilize time zone support.

就需要确认数据时区设置的问题 MySQL 修改时区

遇到问题可以通过 $EK_HOME/logs/error.log 定位、解决
