## 报错如下 ##

zookeeper3节点集群部署完成后，修改配置文件后，无法启动，  
甚至启动失败

[root@centos conf]# zkServer.sh start
    ZooKeeper JMX enabled by default
    Using config: /usr/local/src/zookeeper-3.5.8/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED
    [root@centos conf]# zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /usr/local/src/zookeeper-3.5.8/bin/../conf/zoo.cfg
    Error contacting service. It is probably not running.

[root@centos conf]# zkServer.sh start
    ZooKeeper JMX enabled by default
    Using config: /usr/local/src/zookeeper-3.5.8/bin/../conf/zoo.cfg
    Starting zookeeper ... FAILE TO STARTED
    [root@centos conf]# zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /usr/local/src/zookeeper-3.5.8/bin/../conf/zoo.cfg
    Error contacting service. It is probably not running.

## 解决办法： ##

*  检查防火墙，需要开放2181端口或者关闭防火墙
 *  确保配置文件里的myid与server后面参数的对应正确

dataDir=/data/zookeeper
    clientPort=2181
    tickTime=2000
    initLimit=20
    syncLimit=10
    server.1=192.168.10.2:2888:3888
    server.2=192.168.10.1:2888:3888
    server.3=192.168.10.7:2888:3888

[root@localhost ~]# cat /data/zookeeper/myid 
    1
    [root@localhost ~]# 
    ##########################################
    2,3节点依次根据配置文件自己一一对应

*  如果还是启动不了，检查你是不是版本选错了  
    zookeeper官网最新版`zookeeper3.5.5`版本以后，我们需要下载的包是apache-zookeeper-3.5.x-bin.tar.gz  
    带`bin`才是二进制编译完后的包，我们可以直接使用  
    而之前的普通的`tar.gz`的包里面是只是源码的包无法直接使用
