Question

我正在尝试在 ubuntu EC2 计算机上设置3个Kafka经纪人。但是我在ConnectException开始时获得zookeeper。 <{1}}我的security group内容中的所有端口都已打开。

下面是堆栈跟踪：

ec2

以下是配置：

zookeeper.properties ：

server.properties ：

dataDir=/tmp/zookeeper
clientPort=2181
maxClientCnxns=0

server.1=52.37.XX.70:2888:3888
server.2=52.36.XXX.181:2888:3888
server.3=52.37.XX.42:2888:3888
initLimit=5
syncLimit=2

我已在实例的 / etc / hosts 中添加了服务器的公共IP。我修改的/ etc / hosts如下：

broker.id=1
port=9092
host.name=52.37.XX.70

num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/tmp/kafka-logs
num.partitions=3
num.recovery.threads.per.data.dir=1
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
log.cleaner.enable=false

zookeeper.connect=52.37.XX.70:2181,52.36.XXX.181:2181,52.37.XX.42:2181
zookeeper.connection.timeout.ms=6000

127.0.0.1 localhost localhost.localdomain ip-10-131-X-217 127.0.0.1 localhost localhost.localdomain 52.37.XX.70 127.0.0.1 localhost # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts中的唯一myid条目也会正确输入。

我已按照How to create a MultiNode - MultiBroker Cluster for Kafka on AWS

中提到的所有步骤进行操作

问题是因为我使用的是服务器的<html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> .positionedAbsolute { position: absolute; left: 0; top: 0; /* Doesn't appear to be required but putting it in for good measure. */ } .positionedRelative { position: relative; top: 300px; left: 320px; } .justifiedBottom { padding: 5px; background-color: rgba(200,200,200,0.5); position: fixed; bottom: 0; left: 0; right: 0; } </style> </head> <body> <div class="positionedAbsolute"> <div class="positionedRelative"> Hello </div> </div> <div class="justifiedBottom">Next Page</div> </body> </html>。而不是那样，使用Public IP Public DNS个实例修复了问题。
