zookeeper环境搭建与启动

解压

[root@localhost zookeeper-3.4.6]# tar zxvf zookeeper-3.4.6.tar.gz
[root@localhost zookeeper-3.4.6]# pwd
/home/zookeeper/zookeeper-3.4.6
[root@localhost zookeeper-3.4.6]#

新建目录：

[root@localhost zookeeper-3.4.6]# mkdir data
进入目录：cd conf
/home/zookeeper/zookeeper-3.4.6/conf

修改名字

[root@localhost conf]# mv zoo_sample.cfg zoo.cfg

编辑文件

vim zoo.cfg
