zookeeper的Linux下安装和使用单机版/集群版-优快云博客

本文链接：https://blog.youkuaiyun.com/qq_38872310/article/details/79991196

这个是单节点的，集群的在另一篇文章里做了说明

一、解压zookeeper的tar包

二、到zookeeper的conf目录下，拷贝zoo_sample.cfg 为zoo.cfg。记住名字必须叫zoo.cfg

[root@VM_0_7_centos conf]# cp zoo_sample.cfg zoo.cfg
[root@VM_0_7_centos conf]# ls
configuration.xsl  log4j.properties  zoo.cfg  zoo_sample.cfg

三、创建zookeeper的数据目录和日志目录，并记住目录的绝对路径。我把两个文件夹放在zookeeper的目录下了

[root@VM_0_7_centos zookeeper3.4]# pwd
/usr/app/zookeeper3.4
[root@VM_0_7_centos zookeeper3.4]# mkdir data
[root@VM_0_7_centos zookeeper3.4]# mkdir logs
[root@VM_0_7_centos zookeeper3.4]# ls
bin         docs             NOTICE.txt            zookeeper-3.4.11.jar.asc
build.xml   ivysettings.xml  README.md             zookeeper-3.4.11.jar.md5
conf        ivy.xml          README_packaging.txt  zookeeper-3.4.11.jar.sha1
contrib     lib              recipes
data        LICENSE.txt      src
dist-maven  logs             zookeeper-3.4.11.jar

四、修改zoo.cfg

dataDir=/usr/app/zookeeper3.4/data 对应我上面创建的data目录

dataLogDir=/usr/app/zookeeper3.4/logs 对应我上面创建的logs目录

五、配置zookeeper的环境变量

vim /etc/profile

export ZOOKEEPER_HOME=/usr/app/zookeeper3.4/（Zookeeper所在的目录）

export PATH=$PATH:$ZOOKEEPER_HOME/bin

source /etc/profile 重新载入使配置生效

六、启动zookeeper

[root@VM_0_7_centos zookeeper3.4]# ./bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/app/zookeeper3.4/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

[root@VM_0_7_centos zookeeper3.4]# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/app/zookeeper3.4/bin/../conf/zoo.cfg
Mode: standalone

表示已经启动了

查看详细的启动信息

[root@VM_0_7_centos zookeeper3.4]# ps -ef| grep zookeeper

集群版，在单机版的基础上添加了本节点的zookeeper ID，已用做投票选举的依据。
