今天用自己写的脚本启动zookeeper集群(用hadoop102启动自己及hadoop103,hadoop104)的时候突然报错如下:

Error contacting service. It is probably not running.

网上找了很久也没解决,查看zookeeper.out报的错误如下:

Cannot open channel to 2 at election address hadoop103/192.168.10.103:3888

java.net.ConnectException: 拒绝连接 (Connection refused)

我ssh免密登录也配了,扑所迷离的问题....

然后我查看自己写的脚本如下:

#!/bin/bash
echo "-------------------正在启动zookeeper集群-------- "
ssh root@hadoop102 '/opt/module/zookeeper-3.4.6/bin/zkServer.sh start'
ssh root@hadoop103 '/opt/module/zookeeper-3.4.6/bin/zkServer.sh start'
ssh root@hadoop104 '/opt/module/zookeeper-3.4.6/bin/zkServer.sh start'
echo "-------------------查看是否启动成功及状态信息----------- "
echo "---------------hadoop102查看--------"
ssh root@hadoop102 'source /etc/profile;jps;/opt/module/zookeeper-3.4.6/bin/zkServer.sh status'
echo "---------------hadoop103查看--------"
ssh root@hadoop103 'source /etc/profile;jps;/opt/module/zookeeper-3.4.6/bin/z
