Cloudera CDH 5集羣搭建（yum 方式）

 

1      集羣環境

主節點

master001 ~~ master006

從節點

slave001 ~~ slave064

2      安裝CDH5的YUM源

rpm -Uvhhttp://archive.cloudera.com/cdh5/one-click-install/redhat/6/x86_64/cloudera-cdh-5-0.x86_64.rpm

或

wgethttp://archive.cloudera.com/cdh5/redhat/6/x86_64/cdh/cloudera-cdh5.repo

mv cloudera-cdh5.repo /ect/yum.repo.d/

 

3      ZooKeeper

3.1    節點分配

ZooKeeperServer :

master002,master003, master004, master005, master006

ZooKeeperClient :

master001,master002, master003, master004, master005, master006

 

3.2    安裝

ZooKeeper Client節點:

yum install -y zookeeper

ZooKeeper Server節點:

yum install -y zookeeper-server

3.3    配置

1.zookeeper節點改動zookeeper配置文件

/etc/zookeeper/conf/zoo.cfg

maxClientCnxns=50

# Thenumber of milliseconds of each tick

tickTime=2000

# Thenumber of ticks that the initial

#synchronization phase can take

initLimit=10

# Thenumber of ticks that can pass between

# sendinga request and getting an acknowledgement

syncLimit=5

# thedirectory where the snapshot is stored.

dataDir=/data/disk01/zookeeper/zk_data

dataLogDir=/data/disk01/zookeeper/zk_log

# theport at which the clients will connect

clientPort=2181

 

server.2=master002:2888:3888

server.3=master003:2888:3888

server.4=master004:2888:3888

server.5=master005:2888:3888

server.6=master006:2888:3888

 

2.初始化節點

master002:

service zookeeper-server init --myid=2

master003:

service zookeeper-server init --myid=3

master004:

service zookeeper-server init --myid=4

master005:

service zookeeper-server init --myid=5

master006:

service zookeeper-server init --myid=6

3.執行zookeeper

service zookeeper-server start

 

3.4    安裝路徑

程序路徑

/usr/lib/zookeeper/

配置文件路徑

/etc/zookeeper/conf

日誌路徑

/var/log/zookeeper

3.5    執行|關閉|查看狀態

ZooKeeper

service zookeeper-server start|stop|status

 

3.6    常用命令

查看ZooKeeper節點狀態

zookeeper-server status

 

手動清理日誌

/usr/lib/zookeeper/bin/zkCleanup.shdataLogDir [snapDir] -n count

本身主動清理日誌

autopurge.purgeInterval 這個參數指定了清理頻率，單位是小時，需要填寫一個1或更大的整數，默認是0，表示不開啓本身清理功能。

autopurge.snapRetainCount 這個參數和上面的參數搭配使用，這個參數指定了需要保留的文件數目。默認是保留3個。

# Forexample:

#HBASE_ROOT_LOGGER=INFO,DRFA

# Thereason for changing default to RFA is to avoid the boundary case of filling outdisk space as

# DRFAdoesn't put any cap on the log size. Please refer to HBase-5655 for morecontext.
