zookeeper集群部署

zookeeper集群部署 zookeeper集群搭建

1.环境信息

IP:10.1.33.47 10.1.33.48 10.1.33.49
软件版本:1-zookeeper-3.4.8.tar.gz jdk-8u201-linux-x64.tar.gz
软件存放路径:/app/java   /app/zookeeper-3.4.8

2.安装JDK

解压JDK   
   tar -xzvf jdk-8u201-linux-x64.tar.gz
   
配置JDK环境变量
    1.进入JDK解压后的路径 pwd（JDK解压后的路径）
    2.vim /etc/profile 添加
      JAVA_HOME=/app/java/jdk1.8.0_201
	  CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
	  PATH=$JAVA_HOME/bin:$PATH
      export JAVA_HOME
      export CLASSPATH
      export PATH
     
引入配置的信息（刷新） 
    source /etc/profile
    
查看
   Java -version

3.安装zookeeper

1.解压zookeeper
   tar -xzvf 1-zookeeper-3.4.8.tar.gz   zookeeper-3.4.8(解压后的名字)
   
2.修改zookeeper配置文件名称
   [root@localhost-149 conf]# mv zoo_sample.cfg zoo.cfg


3.创建zookeeper的数据目录和日志文件
    mkdir zk  mkdir data/logs  路径 /app/zookeeper-3.4.8/zk/data

4.修改配置文件 vim zoo.cfg的内容
    dataDir=/app/zookeeper-3.4.8/zk/data
    dataLogDir=/app/zookeeper-3.4.8/zk/logs
    在最下面添加
    #2888 选举端口
    #3888 心跳端口
    server.1=zk47:2888:3888
    server.2=zk48:2888:3888
    server.3=zk49:2888:3888
    
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/app/zookeeper-3.4.8/zk/data
dataLogDir=/app/zookeeper-3.4.8/zk/logs
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1


#2888 选举端口
#3888 心跳端口
server.1=zk47:2888:3888
server.2=zk48:2888:3888
server.3=zk49:2888:3888


5.进入data目录下 创建myid
  ZK47 /app/zookeeper-3.4.8/zk/data/myid --1  	
  ZK48 /app/zookeeper-3.4.8/zk/data/myid --2  
  ZK49 /app/zookeeper-3.4.8/zk/data/myid --3  
  
6.修改本机的hosts
   vim /etc/hosts
    10.1.33.47 zk47
    10.1.33.48 zk48
    10.1.33.49 zk49

4.集群启动测试

启动目录：
 /app/zookeeper-3.4.8/bin 
进入bin目录下进行启动 
 ./zkServer.sh start
查看集群的状态
 ./zkServer.sh status

1.启动防火墙 systemctl start firewalld

2.禁用防火墙 systemctl stop firewalld

3.设置开机启动 systemctl enable firewalld

4.停止并禁用开机启动 sytemctl disable firewalld
