centos8安装zookeeper-3.8

1.下载地址：

Index of /apache/zookeeper/zookeeper-3.8.0

2.解压

tar -xvf apache-zookeeper-3.8.0-bin.tar

3.重命名

mv apache-zookeeper-3.8.0-bin zookeeper-3.8.0

1.创建数据目录

cd /usr/local
mkdir data
cd /usr/local/data
mkdir zookeeper

2.修改配置文件

cd  /usr/local/zookeeper-3.8.0/conf

3.拷贝配置文件并命名为zoo.cfg

cp zoo_sample.cfg zoo.cfg

4.修改配置

# 改成自己的目录配置
dataDir=/usr/local/data/zookeeper

5.添加zookeeper系统变量

vim /etc/profile

在最后添加配置

export ZK_HOME=/usr/local/zookeeper-3.8.0
export PATH=$ZK_HOME/bin:$PATH

1.添加java配置到zkEnv.sh

vim zkEnv.sh

添加java的环境变量

2.增加systemd zookeeper.service服务

cd /etc/systemd/system/
vim zookeeper.service

输入内容如下：

 [Unit]
Description=zookeeper.service
After=network.target
ConditionPathExists=/usr/local/zookeeper-3.8.0/conf/zoo.cfg
[Service]
Type=forking
User=root
Group=root
ExecStart=/usr/local/zookeeper-3.8.0/bin/zkServer.sh start
ExecStop=/usr/local/zookeeper-3.8.0/bin/zkServer.sh stop
[Install]
 WantedBy=multi-user.target

3.测试zookeeper.service

将服务加到系统中：systemctl daemon-reload

启动：systemctl start zookeeper

查看zookeeper的状态

systemctl status zookeeper

停止：systemctl stop zookeeper 

 从web界面可以看到zookeeper状态也是启动的
