Zookeeper安裝和基礎配置

1. zookeeper官網

   https://zookeeper.apache.org/

2. 安裝環境

   部署ip	部署軟體	開放埠
   192.168.199.10	jdk1.8/zookeeper-3.5.8	2181

3. 依賴環境安裝

   tar -zxvf jdk-8u211-linux-x64.tar.gz
   mv jdk1.8.0_211 /opt/
   vi  /etc/profile
   #根據實際情況修改JAVA_HOME
   export JAVA_HOME=/opt/jdk1.8.0_211
   export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
   export PATH=$PATH:$JAVA_HOME/bin
   source /etc/profile
   #測試
   java -version
    
   

4. zookeeper安裝

   mkdir -p /data/zookeeper
   tar zxzf apache-zookeeper-3.5.8-bin.tar.gz
   mv apache-zookeeper-3.5.8-bin /data/zookeeper/zookeeper-3.5.8
   mkdir -p /data/zookeeper/zookeeper-3.5.8/{data,logs}
   

5. 基礎配置

   vim /data/zookeeper/zookeeper-3.5.8/conf/zoo.cfg
   
   tickTime=2000
   initLimit=10
   syncLimit=5
   dataDir=/data/zookeeper/zookeeper-3.5.8/data
   dataLogDir=/data/zookeeper/zookeeper-3.5.8/logs
   clientPort=2181
   
    
   

6. 配置啟動指令碼

   vim /usr/lib/systemd/system/zookeeper.service
   
   [Unit]
   Description=zookeeper
   After=network.target remote-fs.target nss-lookup.target
   [Service]
   Type=forking
   ExecStart=/data/zookeeper/zookeeper-3.5.8/bin/zkServer.sh start
   ExecReload=/data/zookeeper/zookeeper-3.5.8/bin/zkServer.sh restart
   ExecStop=/data/zookeeper/zookeeper-3.5.8/bin/zkServer.sh stop
   [Install]
   WantedBy=multi-user.target
   
   systemctl daemon-reload
    
   

7. 開機自啟動設定

   # 加入開機啟動
   systemctl daemon-reload
   systemctl enable zookeeper
   # 檢視開機是否啟動成功
   systemctl is-enabled zookeeper
   # 啟動服務
   systemctl start zookeeper
   # 停止服務
   systemctl stop zookeeper
   

8. 防火牆開放埠

   firewall-cmd --zone=public --add-port=2181/tcp --permanent
   firewall-cmd --reload
   setenforce 0
