1.准备zookeeper用户

groupadd zookeeperuseradd  -M -s /bin/false -g zookeeper zookeeper

2.准备工作目录

mkdir -p /zookeeper/{data,conf,logs,src}wget -P /zookeeper/src https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gztar zxf /zookeeper/src/zookeeper-3.4.13.tar.gzchown zookeeper.zookeeper -R /zookeeperchmod 750 -R /zookeeperln -s /zookeeper/src/zookeeper-3.4.13 /opt/zookeeper

3.创建zookeeper配置文件：/zookeeper/conf/zoo.cfg

• Standalone模式：

tickTime=2000initLimit=10syncLimit=5clientPort=2181dataDir=/zookeeper/datadataLogDir=/zookeeper/data/logs

• Clustered模式：

tickTime=2000initLimit=10syncLimit=5clientPort=2181dataDir=/zookeeper/datadataLogDir=/zookeeper/data/logsserver.1=zk1:2888:3888server.2=zk2:2888:3888server.3=zk3:2888:3888

Clustered模式下需要创建myid文件，节点对应id：echo "1" > /zookeeper/data/myid

4.编写systemd.service服务脚本：/etc/systemd/system/zookeeper.service

[Unit]Description=ZooKeeper ServiceAfter=network.targetAfter=syslog.target[Service]Environment=ZOO_LOG_DIR=/zookeeper/logsSyslogIdentifier=zookeeperType=forkingUser=zookeeperGroup=zookeeperExecStart=/opt/zookeeper/bin/zkServer.sh start /zookeeper/conf/zoo.cfgExecStop=/opt/zookeeper/bin/zkServer.sh stop /zookeeper/conf/zoo.cfgExecReload=/opt/zookeeper/bin/zkServer.sh restart /zookeeper/conf/zoo.cfg[Install]WantedBy=default.target

重新加载配置信息：systemctl daemon-reload

启动zookeeper：systemctl start zookeeper.service

关掉zookeeper：systemctl stop zookeeper.service

查看进程状态及日志：systemctl status zookeeper.service

开机自启动：systemctl enable zookeeper.service

关闭自启动：systemctl disable zookeeper.service
