ZooKeeper单机版安装配置

yum安装jdk

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]#  yum -y install java-1.8.0-openjdk*

配置变量

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# vim /etc/profile
export JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

使其生效

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# source /etc/profile
[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)

安装ZooKeeper

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz
[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# tar zxf zookeeper-3.4.14.tar.gz -C /usr/local/
[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# ln -sv /usr/local/zookeeper-3.4.14/ /usr/local/zookeeper
‘/usr/local/zookeeper’ -> ‘/usr/local/zookeeper-3.4.14/’

设置配置文件

zookeeper默认读取的是conf/zoo.cfg配置文件

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# cp /usr/local/zookeeper/conf/zoo_sample.cfg /usr/local/zookeeper/conf/zoo.cfg

配置zookeeper启动服务脚本

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# vim /etc/init.d/zookeeper
#!/bin/bash
# chkconfig: 2345 10 90
# description: zookeeper
#Blog:blog.whsir.com
case $1 in
    start) /usr/local/zookeeper/bin/zkServer.sh start
    ;;
    stop) /usr/local/zookeeper/bin/zkServer.sh stop
    ;;
    status) su root /usr/local/zookeeper/bin/zkServer.sh status
    ;;
    restart) su /usr/local/zookeeper/bin/zkServer.sh restart
    ;;
    *) echo "require start|stop|status|restart"
    ;;
esac

赋予执行权限

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# chmod +x /etc/init.d/zookeeper
[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# chkconfig --add zookeeper
[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# /etc/init.d/zookeeper start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

连接测试

zookeeper默认连接端口2181，这里测试下客户端连接

如果连接本地zookeeper则直接运行bin目录下的zkCli.sh即可，如果要连接远程的zookeeper服务，则使用-server参数

[root@iZ2zeflzb6atg5mhyyxn7oZ ~]# /usr/local/zookeeper/bin/zkCli.sh -server 127.0.0.1:2181
