zookeeper集群 启动
1.问题现象。 启动每一个都提示 STARTED 但是查看 status时全部节点都报错
[root@ip-172-31-19-246 bin]# sh zkServer.sh startZooKeeper JMX enabled by defaultUsing config: /usr/local/zookeeper-3.4.8/bin/../conf/zoo.cfgStarting zookeeper … STARTED[root@ip-172-31-29-48 bin]# sh zkServer.sh statusZooKeeper JMX enabled by defaultUsing config: /usr/local/zookeeper-3.4.8/bin/../conf/zoo.cfgError contacting service. It is probably not running.
2.打印日志 看报错 全部节点都报这个错误
tail -1000f zookeeper.out

3.网上寻求解决方案
1.http://freeman983.iteye.com/blog/2053037 log目录没有创建导致出错 并不是原因。
2.http://blog.csdn.net/qianggezhishen/article/details/49363349 （我的配置都是对的 但是仍然报错）
=0.0.0.0:2888:3888
server.2=192.168.10.10:2888:3888
server.3=192.168.2.1:2888:3888
Step 1:
Node 1:
zoo.cfg
server.1= 0.0.0.0:<port>:<port2>
server.2= <IP>:<port>:<port2>
.
.
.
server.n= <IP>:<port>:<port2>
Node 2 :
server.1= <IP>:<port>:<port2>
server.2= 0.0.0.0:<port>:<port2>
.
.
.
server.n= <IP>:<port>:<port2>
如愿看到：

如果遇到 java.net.NoRouteToHostException: No route to host
建议关闭防火墙试试
Java.net.NoRouteToHostException:No route to host
上网查询的结论如下：
没有路由连接到本机，无法到达远程主机，
原因：防火墙干扰或中间路由器停机
(用telnet查看该机器是否正常连接，结果如下：
Trying 199.155.122.91…
telnet: connect to address 199.155.122.91: No route to host
telnet: Unable to connect to remote host: No route to host)
解决的办法是：和防火墙规则有关，关闭防火墙就可以了
关闭防火墙之后，结果如下：
Trying 199.155.122.91…
telnet: connect to address 199.155.122.91: Connection refused
telnet: Unable to connect to remote host: Connection refused
