zookeeper-8080端口关闭

Posted 2023-04-07

参考技术A !  zookeeper的内嵌管理控制台是由jetty启动的，默认为http端口为8080；存在一定的信息泄露及安全隐患,如无必要建议禁用。

在bin/zkServer.sh文件中，nohup下加一条参数关闭服务 "-Dzookeeper.admin.enableServer=false"  重新启动zk 8080端口就没了

vim hadoop-env.sh

Spark集群安装-基于hadoop集群

Zookeeper

1. 下载解压
   https://downloads.apache.org/zookeeper/stable/apache-zookeeper-3.6.3-bin.tar.gz

wget https://downloads.apache.org/zookeeper/stable/apache-zookeeper-3.6.3-bin.tar.gz
tar -zxvf apache-zookeeper-3.6.3-bin.tar.gz
mv apache-zookeeper-3.6.3-bin /usr/local/zookeeper

2. 配置zoo.cfg

cd /usr/local/zookeeper/conf
cp zoo_sample.cfg zoo.cfg
vim zoo.cfg

dataDir=/data/zookeeper/data/
dataLogDir=/data/zookeeper/logs/
quorumListenOnAllIPs=true
admin.serverPort=8181
server.1=hadoop1:2888:3888
server.2=hadoop2:2888:3888

3. 配置myid

mkdir -p /data/zookeeper/
cd /data/zookeeper/
mkdir data logs
cd data
vim myid

4. 同步

scp -r /usr/local/zookeeper/ hadoop2:/usr/local/

5. 启动
   在各个节点启动zookeeper

cd /usr/local/zookeeper/bin
./zkServer.sh start

Hbase

IDEA远程连接HBase及其Java API实战当时这篇是单机的，没介绍集群，步骤基本一致。

1. 下载解压

wget https://downloads.apache.org/hbase/2.3.5/hbase-2.3.5-src.tar.gz
tar -zxvf hbase-2.3.5-src.tar.gz
mv hbase-2.3.5 /usr/local/hbase

2. 配置hbase-site.xml

cd /usr/local/hbase/conf
vi hbase-site.xml

  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
  <property>
    <name>hbase.tmp.dir</name>
    <value>./tmp</value>
  </property>
  <property>
    <name>hbase.unsafe.stream.capability.enforce</name>
    <value>true</value>
  </property>
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://hadoop1:9000/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>hadoop1:2181,hadoop2:2181</value>
    <description>The directory shared by RegionServers. </description>
  </property>
  <property>
    <name>hbase.master.info.port</name>
    <value>16010</value>
  </property>
  <property>
    <name>zookeeper.session.timeout</name>
    <value>90000</value>
    <source>hbase-default.xml</source>
  </property>

3. 配置hbase-env.sh

cd /usr/local/hbase/conf
echo $JAVA_HOME
vi hbase-env.sh #添加和你输出的JAVA_HOME一致

export JAVA_HOME=/usr/local/jdk1.8
export HBASE_MANAGES_ZK=false

4. 设置从节点

cd /usr/local/hbase/conf
vi regionservers

5. 同步
   将主节点Hbase配置同步给从节点

scp -r /usr/local/hbase/ hadoop2:/usr/local/

6. 启动测试
   记得先启动zookeeper和hadoop

cd /usr/local/hbase/bin
./start-hbase.sh
