    大早上剛到公司就發(fā)現(xiàn)報(bào)警，磁盤容量告警，zookeeper集群服務(wù)器報(bào)警。

二、處理過程

1. 查看磁盤空間

df -h

2.確認(rèn)那個(gè)目錄占用空間比較多，發(fā)現(xiàn)是zookeeper

修改zookeeper參數(shù)文件（版本3.4.6）

vi zoo.cfg

# The number of snapshots to retain in dataDir

autopurge.snapRetainCount=20    #保留log和snapshot各20個(gè)

# Purge task interval in hours

# Set to "0" to disable auto purge feature

autopurge.purgeInterval=1    #每小時(shí)清理一次

3.查看狀態(tài)

$ /usr/local/RoilandGroup/zookeeper/bin/zkServer.sh status

JMX enabled by default

Using config: /usr/local/RoilandGroup/zookeeper/bin/../conf/zoo.cfg

Mode: leader

4.關(guān)閉服務(wù)

$ /usr/local/RoilandGroup/zookeeper/bin/zkServer.sh stop

JMX enabled by default

Using config: /usr/local/RoilandGroup/zookeeper/bin/../conf/zoo.cfg

Stopping zookeeper ... STOPPED

5.重啟服務(wù)

$ /usr/local/RoilandGroup/zookeeper/bin/zkServer.sh start

JMX enabled by default

Using config: /usr/local/RoilandGroup/zookeeper/bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

[hadoop@host-10-60-40-37 conf]$ jps

8118449 QuorumPeerMain

6.zookeeper集群中每一個(gè)節(jié)點(diǎn)都需要修改參數(shù)文件，然后重啟服務(wù).

至于為什么這么修改，是否還有其他的方式，大家可以看官方文檔，或者比較懶就百度。

7.理解每一個(gè)參數(shù)文件，看注釋就行

less 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=/data/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.

#

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

#

# The number of snapshots to retain in dataDir

autopurge.snapRetainCount=20

# Purge task interval in hours

# Set to "0" to disable auto purge feature

autopurge.purgeInterval=1
