linux 系统下 zookeeper 安装教程:
1.下载安装包
1）进入安装目录
cd /home/install/
2）下载
wget http://mirror.bit.edu.cn/apache/zookeeper/stable/zookeeper-3.4.12.tar.gz
2.安装
1）创建和解压至安装目录
mkdir /usr/local/zookeeper
tar -zxcf /home/install/zookeeper-3.4.12.tar.gz -C /usr/local/zookeeper/
2）拷贝样本配置为主配置
进入配置目录，赋值拷贝样本文件
cd /usr/local/zookeeper/zookeeper-3.4.12/conf/
cp zoo_sample.cfg zoo.cfg
3）简单修改配置
创建数据存储目录与日志目录
mkdir /usr/local/zookeeper/zookeeper-3.4.12/dataDir
mkdir /usr/local/zookeeper/zookeeper-3.4.12/dataLogDir
修改数据存储和日志目录
vim /usr/local/zookeeper/zookeeper-3.4.12/conf/zoo.cfg
3.配置zookeeper环境变量
1）依赖JVM环境，所以JVM与zookeeper环境变量都要配置
vim /etc/profile
在尾部加入或修改以下
JAVA_HOME=/usr/local/java/jdk1.8.0_181 CLASSPATH=$JAVA_HOME/lib/ PATH=$PATH:$JAVA_HOME/bin export PATH JAVA_HOME PATH ZOOKEEPER_HOME=/usr/local/zookeeper/zookeeper-3.4.12 PATH=$PATH:$ZOOKEEPER_HOME/bin export PATH ZOOKEEPER_HOME PATH
2)生效
source /etc/profile
3.测试
1）启动
/usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh start
2）连接
/usr/local/zookeeper/zookeeper-3.4.12/bin/zkCli.sh
3）增删改查
4）其他
help查看指令帮助
4.开机启动
（1）编辑zookeeper.service文件
vim /usr/lib/systemd/system/zookeeper.service
加入如下内容
[Unit] Description=zookeeper After=network.target remote-fs.target nss-lookup.target [Service] Type=forking ExecStart=/usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh start ExecReload=/usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh restart ExecStop=/usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh stop [Install] WantedBy=multi-user.target
（2）生效
systemctl daemon-reload
（3）改变文件权限
chmod 777 /usr/lib/systemd/system/zookeeper.service
（4）systemctl开机启动zookeeper
systemctl enable /usr/lib/systemd/system/zookeeper.service
或
systemctl enable /usr/lib/systemd/system/zookeeper
（5）查看是否开机启动
systemctl is-enabled zookeeper.service
（6）systemctl取消开机启动redis
systemctl disable zookeeper.service
