本文详细介绍如何在Linux环境下安装和配置ZooKeeper集群，包括用户准备、工作目录设置、配置文件编写及systemd服务脚本创建等步骤，并提供启动、停止及开机自启动的方法。

1.准备zookeeper用户

groupadd zookeeper
useradd  -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.gz
tar zxf /zookeeper/src/zookeeper-3.4.13.tar.gz
chown zookeeper.zookeeper -R /zookeeper
chmod 750 -R /zookeeper
ln -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=2000
initLimit=10
syncLimit=5
clientPort=2181
dataDir=/zookeeper/data
dataLogDir=/zookeeper/data/logs

Clustered模式：

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

server.1=zk1:2888:3888
server.2=zk2:2888:3888
server.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 Service
After=network.target
After=syslog.target

[Service]
Environment=ZOO_LOG_DIR=/zookeeper/logs
SyslogIdentifier=zookeeper

Type=forking
User=zookeeper
Group=zookeeper
ExecStart=/opt/zookeeper/bin/zkServer.sh start /zookeeper/conf/zoo.cfg
ExecStop=/opt/zookeeper/bin/zkServer.sh stop /zookeeper/conf/zoo.cfg
ExecReload=/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
