linux 系統下 zookeeper 安裝教程
1.下載安裝包
(說明：截圖來自之前的博客文檔，與現在安裝不是完全一樣請按照文字步驟操作，截圖僅供參考）
1）進入安裝目錄
cd /home/install/
2）下載
wget http://mirror.bit.edu.cn/apache/zookeeper/stable/apache-zookeeper-3.5.8-bin.tar.gz
2.安裝
1）解壓至安裝目錄
tar -zxcf /home/install/apache-zookeeper-3.5.8-bin.tar.gz -C /usr/local/
mv /usr/local/apache-zookeeper-3.5.8-bin /usr/local/zookeeper
2）拷貝樣本配置為主配置
進入配置目錄，賦值拷貝樣本文件
cd /usr/local/zookeeper/conf/
cp zoo_sample.cfg zoo.cfg
3）簡單修改配置
創建數據存儲目錄與日志目錄
mkdir /usr/local/zookeeper/dataDir
mkdir /usr/local/zookeeper/dataLogDir
修改數據存儲和日志目錄
vim /usr/local/zookeeper/conf/zoo.cfg
3.配置zookeeper環境變量
1）依賴JVM環境，所以JVM與zookeeper環境變量都要配置
vim /etc/profile
在尾部加入或修改以下
JAVA_HOME=/usr/local/java/jdk1.8.0_231
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME PATH
ZOOKEEPER_HOME=/usr/local/zookeeper
PATH=$PATH:$ZOOKEEPER_HOME/bin
export PATH ZOOKEEPER_HOME PATH
2)生效
source /etc/profile
3.測試
1）啟動
/usr/local/zookeeper/bin/zkServer.sh start
2）連接
/usr/local/zookeeper/bin/zkCli.sh
3）增刪改查
4）其他
help查看指令幫助
4.開機啟動
（1）編輯zookeeper.service文件
vim /usr/lib/systemd/system/zookeeper.service
加入如下內容
[Unit] Description=zookeeper After=network.target remote-fs.target nss-lookup.target [Service] Type=forking ExecStart=/usr/local/zookeeper/bin/zkServer.sh start ExecReload=/usr/local/zookeeper/bin/zkServer.sh restart ExecStop=/usr/local/zookeeper/bin/zkServer.sh stop [Install] WantedBy=multi-user.target
（2）zookeeper.service文件生效
systemctl daemon-reload
（3）設置開機啟動
systemctl enabled zookeeper.service
（4）啟動
systemctl start zookeeper.service
（5）關閉
systemctl stop zookeeper.service
（6）重啟
systemctl restart zookeeper.service
（7）查看是否開機啟動
systemctl is-enabled zookeeper.service
（8）systemctl取消開機啟動redis
systemctl disable zookeeper.service
