Hadoop 2.7.3 完全分布式维护-部署篇

测试环境如下

IP	host	JDK	linux	hadop	role
172.16.101.55	sht-sgmhadoopnn-01	1.8.0_111	CentOS release 6.5	hadoop-2.7.3	NameNode,SecondaryNameNode,ResourceManager
172.16.101.58	sht-sgmhadoopdn-01	1.8.0_111	CentOS release 6.5	hadoop-2.7.3	DataNode,NodeManager
172.16.101.59	sht-sgmhadoopdn-02	1.8.0_111	CentOS release 6.5	hadoop-2.7.3	DataNode,NodeManager
172.16.101.60	sht-sgmhadoopdn-03	1.8.0_111	CentOS release 6.5	hadoop-2.7.3	DataNode,NodeManager

1. 软件准备

http://www-eu.apache.org/dist/hadoop/common/hadoop-2.7.3/hadoop-2.7.3.tar.gz

http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.tar.gz

2. 系统环境该准备

2.1 创建用户并配置好环境变量

# useradd -r -u  -g dba -G root -d /home/hduser hduser
# echo 'admin123' | passwd --stdin hduser
# cat /home/hduser/.bash_profile
..........

export JAVA_HOME=/usr/java/jdk1..0_111_273
export JRE_HOME=$JAVA_HOME/jre
export HADOOP_HOME=/usr/local/hadoop-2.7.3
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH:$HOME/bin

2.2 解压hadoop和jdk

# tar -zxf jdk-8u144-linux-x64.tar.gz -C /usr/java/
# tar -zxf hadoop-2.7.3.tar.gz -C /usr/local/
# chown -R hduser:dba /usr/local/hadoop-2.7.3/

2.3 设置各主机名与IP地址解析

# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.16.101.55    sht-sgmhadoopnn-
172.16.101.58    sht-sgmhadoopdn-
172.16.101.59    sht-sgmhadoopdn-
172.16.101.60    sht-sgmhadoopdn-

2.4 配置namnode与各datanode节点间的ssh互信

$ ssh-keygen -t rsa
$ ssh-copy-id hduser@sht-sgmhadoopnn-
$ ssh-copy-id hduser@sht-sgmhadoopdn-
$ ssh-copy-id hduser@sht-sgmhadoopdn-
$ ssh-copy-id hduser@sht-sgmhadoopdn-

2.5 同步各节点之间时间
