centos7 安装zookeeper
下载安装包
进入安装目录
cd /home/install/
下载
[root@localhost install]#wget https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz
下载完成
安装
1)创建和解压至安装目录
mkdir /usr/local/zookeeper
tar -xvf zookeeper-3.4.14.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
[root@localhost install]# cd /usr/local/zookeeper/zookeeper-3.4.14/conf/
[root@localhost 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
[root@localhost conf]# mkdir /usr/local/zookeeper/zookeeper-3.4.14/dataDir
[root@localhost conf]# mkdir /usr/local/zookeeper/zookeeper-3.4.14/dataLogDir
修改数据存储和日志目录
[root@localhost conf]# vim /usr/local/zookeeper/zookeeper-3.4.14/conf/zoo.cfg
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
在尾部追加
期间遇到找不到JAVA_HOME,路径不对,可以使用
java -version
查看安装版本,没有安装的话,运行命令:yum -y install java-1.8.0-openjdk.x86_64
JAVA_HOME 可以使用whereis java
查看路径
2)生效
source /etc/profile
测试
启动
/usr/local/zookeeper/zookeeper-3.4.14/bin/zkServer.sh start
连接
/usr/local/zookeeper/zookeeper-3.4.14/bin/zkCli.sh
增删改查
开机启动
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-3.4.14/bin/zkServer.sh start
ExecReload=/usr/local/zookeeper/zookeeper-3.4.14/bin/zkServer.sh restart
ExecStop=/usr/local/zookeeper/zookeeper-3.4.14/bin/zkServer.sh stop
[Install]
WantedBy=multi-user.target
生效
systemctl daemon-reload
改变文件权限
chmod 777 /usr/lib/systemd/system/zookeeper.service
systemctl开机启动zookeeper
systemctl enable /usr/lib/systemd/system/zookeeper.service
或
systemctl enable /usr/lib/systemd/system/zookeeper
查看是否开机启动
systemctl is-enabled zookeeper.service
systemctl取消开机启动
systemctl disable zookeeper.service
