在安装Kafka-eagle的时候遇见几个坑，在这里分享一下：
注意：版本问题，若按本文章不能解决，则着重查看版本的问题；这里只是提供解决针对问题的思路
Kafka版本：kafka_2.11-0.11.0.2
Kafka-eagle版本：kafka-eagle-bin-1.3.7
MySQL版本：5.7.28 MySQL
坑1：关于安装成功之后返回状态页500
需要使用到JMX端口，配置Kafka/bin下的 kafka-server-start.sh：

echo "USAGE: $0 [-daemon] server.properties [--override property=value]*" exit 1
fi base_dir=$(dirname $0) if [ "x$KAFKA_LOG4J_OPTS" = "x" ]; then export KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/../config/log4j.properties"
fi
# 注意：这里是修改后的文件
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
#添加代码如下： export JMX_PORT="9999"
fi EXTRA_ARGS=${EXTRA_ARGS-'-name kafkaServer -loggc'} COMMAND=$1
case $COMMAND in
-daemon) EXTRA_ARGS="-daemon "$EXTRA_ARGS shift ;; *) ;; esac exec $base_dir/kafka-run-class.sh $EXTRA_ARGS kafka.Kafka "$@"
解决：
1. 进入eagle的bin目录下，编辑文件 ke.sh
# 注释掉一下几行代码
#rm -rf $KE_HOME/kms/webapps/ke #rm -rf $KE_HOME/kms/work #mkdir -p $KE_HOME/kms/webapps/ke #cd $KE_HOME/kms/webapps/ke #${JAVA_HOME}/bin/jar -xvf $KE_HOME/kms/webapps/ke.war
2. 进入到 /export/servers/kafka-eagle-bin-1.3.7/eagle/kms/webapps/ke/WEB-INF/lib 删除Jackson开头的jar包
rm -fr jackson-*.jar
3. 启动 zk集群和Kafka集群，然后启动eagle：
# 注意要配置好环境变量，并source zk.sh start
坑2：连接org.sqlite.JDBC没有问题，但是连接MySQL失败，一直进不去Dashboard页面
###################################### # 这里配置自己的集群，我这里只有一套，删除了原来的cluster2 ###################################### kafka.eagle.zk.cluster.alias=cluster1 cluster1.zk.list=node01:2181,node02:2181,node03:2181 ###################################### # 默认即可 ###################################### kafka.zk.limit.size=25 ###################################### # 默认即可 ###################################### kafka.eagle.webui.port=8048 ###################################### # 删除了cluster2，保留1，为Kafka，0.96版本之后，offset信息保存在Kafka集群中 ###################################### cluster1.kafka.eagle.offset.storage=kafka ###################################### # 都设置为true ###################################### kafka.eagle.metrics.charts=true kafka.eagle.sql.fix.error=true ###################################### # 默认即可 ###################################### kafka.eagle.sql.topic.records.max=5000 ###################################### # 默认即可，也可以设置为true ###################################### kafka.eagle.mail.enable=true kafka.eagle.mail.sa=alert_sa@163.com kafka.eagle.mail.username=alert_sa@163.com kafka.eagle.mail.password=mqslimczkdqabbbh kafka.eagle.mail.server.host=smtp.163.com kafka.eagle.mail.server.port=25 ###################################### # 默认 ###################################### #kafka.eagle.im.dingding.enable=true #kafka.eagle.im.dingding.url=https://oapi.dingtalk.com/robot/send?access_token=

# 之前返回500报错，使用sqlite测试 #kafka.eagle.driver=org.sqlite.JDBC #kafka.eagle.url=jdbc:sqlite:/export/servers/kafka-eagle-bin-1.3.7/eagle/db/ke.db #kafka.eagle.username=root #kafka.eagle.password=你的密码
解决：
1. 测试MySQL是否能够让外界连接到
2. 进入到你的MySQL：
-- 进入MySQL, 123456是你的密码
mysql -u root -p123456 -- 使用mysql数据库
use mysql -- 查看user表中的数据 root后面 有没有跟%
select User,Host from user; -- 如果没有，则使用以下命令 这里的root是你的用户名 123456是你的密码
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option; flush privileges; -- 退出，最好使用Windows的MySQL工具连接一下测试
最后，启动eagle，登录查看是否成功！
