Ignoring exception during shutdown input java.nio.channels.ClosedChannelException
一个是:zookeeper最常见的错误：防火墙没关
赶紧去Linux下关闭防火墙: service iptables stop
几条关于防火墙的命令：
1.查看状态：firewall-cmd -state
开启状态：running
关闭状态：not running
2.关闭防火墙：systemctl stop firewalld.service
3.开机不启动防火墙：systemctl disable firewalld.service
第二是:记得查看状态,是否将zkServer开启
