本文主要向大家介绍了【云计算】zookeeper启动无响应解析,通过具体的内容向大家展现,希望对大家学习云计算有所帮助。
zookeeper启动无响应
报错消息如下:
2018-08-16 21:51:35,557 [myid:1] - ERROR [main:QuorumPeerMain@92] - Unexpected exception, exiting abnormally
java.lang.RuntimeException: My id 1 not in the peer list
at org.apache.zookeeper.server.quorum.QuorumPeer.startLeaderElection(QuorumPeer.java:718)
at org.apache.zookeeper.server.quorum.QuorumPeer.start(QuorumPeer.java:637)
at org.apache.zookeeper.server.quorum.QuorumPeerMain.runFromConfig(QuorumPeerMain.java:170)
at org.apache.zookeeper.server.quorum.QuorumPeerMain.initializeAndRun(QuorumPeerMain.java:114)
at org.apache.zookeeper.server.quorum.QuorumPeerMain.main(QuorumPeerMain.java:81)
错误原因:根据报错日志,可以看出,是因为myid文件中配置有误。导致无法找到这个myid=1的peer。
解决办法:根据conf/zoo.cfg中的值配置myid中的值。
查看conf/zoo.cfg文件
[root@server4 conf]# cat zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial synchronization phase can take
initLimit=10
# The number of ticks that can pass between sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just example sakes.
dataDir=/tmp/zookeeper
# 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.
#
# https://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.4=server4:2888:3888
server.5=server5:2888:3888
server.6=server6:2888:3888
看最后三行,这里的server.4中的4就是myid中的文件内容。所以在server4这个主机中,其zookeeper的myid文件内容就是4。server5,server6同理。
修改好myid文件中的内容之后,就可以正常启动了。
