zookeeper 3.4.6安装单机模式教程（centos 下安装） 搭配dubbo 2.8.4

1.下载zookeeper-3.4.6.tar.gz  下载地址  http://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/

2.下载完解压 tar zxvf  zookeeper-3.4.6.tar.gz

3.进入zookeeper-3.4.6 下  cd  zookeeper-3.4.6

4.创建两个文件夹 data ,logs    mkdir data 

5.进入到conf文件夹下 拷贝zoo_sample.cfg   为zoo.cfg

修改 zoo.cfg内容如下  其实就是下图中圈的地方。   注意要加root，绝对路径，路径错了，服务会有问题的

#autopurge.purgeInterval=1

6.启动服务 进入bin目录 ，zkServer.sh start   启动服务。

查看服务启动状态   zkServer.sh status    显示 mode：standalone就表示成功了。
