Zookeeper一直提示连接失败
Zookeeper一直提示连接失败,已经检查几遍了。还是查不出原因,请教各位大牛们?以下是 zoo.cfg配置
dataDir=/opt/src/zookeeper-3.4.7/data
dataLogDir=/opt/src/zookeeper-3.4.7/logs
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=n1:2888:3888
server.2=s1:2888:3888
server.3=S2:2888:3888
server.1=n1:2888:3888
server.2=s1:2888:3888
server.3=S2:2888:3888
三个会竞争端口，导致链接不上。端口可一直递增。
server.1=n1:2888:3888
server.2=s1:2889:3889
server.3=S2:2890:3890

您好!按你的方法改了并测试,好像还是不行.错误如下

应该是防火墙的原因

您好!防火墙我第一时间就关闭了!以下是我配置的图片. hosts配置完以后也没有动过了

为何端口还没有改过来

为何端口还没有改过来
上次改过来也暴错了,就还原了。大神你QQ多少细聊
楼主 不是一个错误，建议多参考几个文档。
server.1=n1:2888:3888
server.2=s1:2888:3888
server.3=S2:2888:3888
三个节点应该是3台主机吧,同一台主机,就要改2888:3888这两个端口;3台主机就不需要改.
在另外两台主机上看是否能telnet n1 2888 / 3888 / 2181,如果telnet过不去,应该是防火墙的原因了
根据日志初步分析是端口不通, szcountryboy 发表于 2016-3-31 15:54
server.1=n1:2888:3888
server.2=s1:2888:3888
server.3=S2:2888:3888
搞定了。 直接用ip就ok了
