老师，我的连接超时了

# 具体遇到的问题

这是我的命令 ./bin/zkCli.sh -server 39.97.251.11:2181 显示连接超时，没有显示welcome to Zookeeper

代码中的是连接超时显示的信息

# 报错信息的截图

# 相关课程内容截图

# 尝试过的解决思路和结果

# 粘贴全部相关代码，切记添加代码注释（请勿截图）

在这里输入代码，可通过选择【代码语言】突出显示

同学你好，

1、同学检查一下zookeeper启动成功了没有，如下：
./bin/Server.sh status

2、关闭防火墙
systemctl stop firewalld.service

再连接试试

同学你好，同学是连接远程的的zookeeper吗？

./bin/zkCli.sh -server 39.97.251.11:2181 显示连接超时，建议同学重新执行命令再试试。

另外建议同学使用ip addr命令查看ip地址是否正确。

建议同学先启动zookeeper，再使用代码链接。

祝：学习愉快~

老师我连接的是远程云服务器上的zookeeper。我使用hostname -I查询了IP地址，显示为172.27.160.232 ，所以我把命令改./bin/zkCli.sh -server 172.27.160.232:2181，终端显示拒绝连接。下面是错误代码，还夹杂些许乱码 Connecting to 172.27.160.232:2181 2020-11-06 12:52:06,203 [myid:] - INFO [main:Environment@98] - Client environment:zookeeper.version=3.6.0--b4c89dc7f6083829e18fae6e446907ae0b1f22d7, built on 02/25/2020 14:38 GMT 2020-11-06 12:52:06,208 [myid:] - INFO [main:Environment@98] - Client environment:host.name=iZ2zea4k45xs2e37aqeqwlZ 2020-11-06 12:52:06,209 [myid:] - INFO [main:Environment@98] - Client environment:java.version=1.8.0_202 2020-11-06 12:52:06,212 [myid:] - INFO [main:Environment@98] - Client environment:java.vendor=Oracle Corporation 2020-11-06 12:52:06,213 [myid:] - INFO [main:Environment@98] - Client environment:java.home=/usr/java/jdk1.8.0_202/jre 2020-11-06 12:52:06,213 [myid:] - INFO [main:Environment@98] - Client environment:java.class.path=/root/apache-zookeeper-3.6.0-bin/bin/../zookeeper-server/target/classes:/root/apache-zookeeper-3.6.0-bin/bin/../build/classes:/root/apache-zookeeper-3.6.0-bin/bin/../zookeeper-server/target/lib/*.jar:/root/apache-zookeeper-3.6.0-bin/bin/../build/lib/*.jar:/root/apache-zookeeper-3.6.0-bin/bin/../lib/
