linux的zookeeper安装遇到的问题

1.我的安装好后启动不起来，查看日志显示：

2019-09-04 18:18:26,064 [myid:1] - WARN  [QuorumPeer[myid=1]/0:0:0:0:0:0:0:0:2181:QuorumCnxManager@382] - Cannot open channel to 3 at election address node03/192.168.17.103:3888

java.net.ConnectException: Connection refused

其实这个不是什么问题的，就是需要你把其他的几台机器启动就ok了，之后我依次把node02----到------node05全部启动

./bin/zkServer.sh start      然后查看状态status就好了

2.还有之前一个占用端口的问题。报错的信息显示如下：

./bin/zkServer.sh start-foreground

查看下端口：

办法，kill掉他就好了。重新启动后问题解决。
