zookeeper-3.4.9搭建

1.解压到指定目录   

[root@master package]# tar -zxvf zookeeper-3.4.9.tar.gz

2.修改Zookeeper的默认配置文件

       2.1 先复制zoo.cfg配置

       首先进入conf目录下，然后先复制 zoo_sample.cfg 并重命名为zoo.cfg。

[root@master zookeeper-3.4.9]# cd conf
[root@master conf]# ls
configuration.xsl  log4j.properties  zoo_sample.cfg
[root@master conf]# cp zoo_sample.cfg  zoo.cfg

        2.2 配置zoo.cfg

[root@master conf]# vim zoo.cfg
