Kafka-manager 安装之 神坑

2022-02-14 18:14:27,580 - [ERROR] - from kafka.manager.actor.cluster.BrokerViewCacheActor in kafka-manager-system-akka.actor.default-dispatcher-6

解决方法

1、修改 kafka-server-start.sh，增加 JMX 的端口信息

kafka_2.12-3.1.0/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 JMX_PORT="9988"
fi

2、修改kafka-run-class.sh，增加绿色部分，注意对应的 ip地址。

 

 

for file in "$base_dir"/core/build/libs/kafka_${SCALA_BINARY_VERSION}*.jar;
do
  if should_include_file "$file"; then
    CLASSPATH="$CLASSPATH":"$file"
  fi
done
shopt -u nullglob

if [ -z "$CLASSPATH" ] ; then
  echo "Classpath is empty. Please build the project first e.g. by running './gradlew jar -PscalaVersion=$SCALA_VERSION'"
  exit 1
fi

# JMX settings
if [ -z "$KAFKA_JMX_OPTS" ]; then
  KAFKA_JMX_OPTS="-Djava.rmi.server.hostname=kafka1.sd.cn -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false  -Dcom.sun.management.jmxremote.
ssl=false "
fi

# JMX port to use
if [  $JMX_PORT ]; then
  KAFKA_JMX_OPTS="$KAFKA_JMX_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT "
fi

# Log directory to use
if [ "x$LOG_DIR" = "x" ]; then
  LOG_DIR="$base_dir/logs"
fi

修改完毕记得重启 kafka 服务
