解决方法

mysql5.7.x版本搭配eagle1.3版本不行，得搭配1.4以上的版本！

问题

最开始，我centos7服务器的mysql版本是5.7.31，eagle的版本是1.3.7，修改完./kafka_2.12-0.11.0.0/bin/kafka-server-start.sh，

if [ $# -lt 1 ];
then
	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

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
    #export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
    export KAFKA_HEAP_OPTS="-server -Xms2G -Xmx2G -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:ParallelGCThreads=6 -XX:ConcGCThreads=2 -XX:InitiatingHeapOccupancyPercent=70"
    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 $EXTRA_ARGS kafka.Kafka "$@"

再修改./eagle/conf/system-config.properties后，发现启动进入登录界面后，一直进不去。

解决

看了很多别人的方法，去看了./eagle/logs/error.log后，觉得是eagle版本太低了，然后将eagle的版本从1.3.7换成了1.4.8后，便成功登录了。

登陆成功的./eagle/conf/system-config.properties配置如下：
