2.4. 配置网络
2.4.1. 配置hosts
配置hosts文件的作用，它主要用于确定每个结点的IP地址，方便后续master结点能快速查到并访问各个节点。在3个虚机节点上均需要配置此文件：
在master、node1、node2中分别添加 | |||||
主机名 | IP址址 | 子网 | 网络类型 | 解析方式 | |
Eth0 | 10.10.36.100 | 255.255.255.0 | 公用网络 |
| |
/etc/hosts | |||||
10.10.36.100 master | NameNode、JobTracker | ||||
10.10.36.101 node1 | DataNode、TaskTracker | ||||
10.10.36.123 node2 | DataNode、TaskTracker | ||||
2.4.2. 配置网络
通过ifdown,ifup使配置的IP生效:
[root@master /]# sudo ifconfig eth0 10.10.36.100 netmask 255.255.255.0 up [root@master /]# ifup eth0 Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/4 [root@master /]#
[root@node1 /]# sudo ifconfig eth0 10.10.36.101 netmask 255.255.255.0 up [root@node1 /]# ifup eth0 Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/4 [root@node1 /]#
[root@node2 /]# sudo ifconfig eth0 10.10.36.123 netmask 255.255.255.0 up [root@node2 /]# ifup eth0 Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/3 [root@node2 /]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0C:29:57:08:7B inet addr:10.10.36.123 Bcast:10.10.36.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe57:87b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:11506 errors:0 dropped:0 overruns:0 frame:0 TX packets:5564 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1090727 (1.0 MiB) TX bytes:538552 (525.9 KiB) Interrupt:19 Base address:0x2024

[root@node2 /]# |
2.5. 配置资源与参数
2.5.1. 修改主机名称
[root@master /]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=master |
[root@node1 /]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=node1 |
[root@node2 /]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=node2 |
2.5.2. 配置用户,组,目录和权
为hadoop集群专门设置一个用户组及用户，这部分比较简单，参考示例如下：
sudo groupadd hadoop //设置hadoop用户组
sudo useradd –s /bin/bash –d /home/uhadoop –m uhadoop –g hadoop –G admin //添加一个uhadoop用户，此用户属于 hadoop用户组，且具有admin权限。
3个虚机节点均需要进行以上步骤来完成hadoop运行帐号的建立。
[root@master /]# sudo groupadd hadoop [root@master /]# sudo groupadd admin [root@master /]# sudo useradd -s /bin/bash -d /home/uhadoop -m uhadoop -g hadoop -G admin [root@master /]# echo -n uhadoop|passwd --stdin uhadoop Changing password for user uhadoop. passwd: all authentication tokens updated successfully.
[root@node1 /]# sudo groupadd hadoop [root@node1 /]# sudo groupadd admin [root@node1 /]# sudo useradd -s /bin/bash -d /home/uhadoop -m uhadoop -g hadoop -G admin [root@node1 /]# echo -n uhadoop|passwd --stdin uhadoop Changing password for user uhadoop. passwd: all authentication tokens updated successfully.
[root@node2 /]# sudo groupadd hadoop [root@node2 /]# sudo groupadd admin [root@node2 /]# sudo useradd -s /bin/bash -d /home/uhadoop -m uhadoop -g hadoop -G admin [root@node2 /]# echo -n uhadoop|passwd --stdin uhadoop Changing password for user uhadoop. passwd: all authentication tokens updated successfully.

2.5.3. 修改系统内核参数/etc/sysctl.conf
[root@linuxrac1 etc]# vi sysctl.conf # add parameter for oracle fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 1073741824 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586 |
2.6. 配置等效性与连通(可选项)
2.6.1. uhadoop用户等效性
1.以下均以uhadoop用户执行: 在两个节点的grid主目录分别创建.ssh目录，并赋予权限 |

3.1.2. 添加hadoop环境变量
在三个节点都添加环境变量 |
[root@master /]# vi /etc/profile # set environment by HondaHsu 2014 JAVA_HOME=/usr/java/jdk1.8.0_25 JRE_HOME=/usr/java/jdk1.8.0_25/jre HADOOP_HOME=/home/uhadoop/uhadoop/hadoop-2.5.2 HADOOP_COMMON_HOME=$HADOOP_HOME HADOOP_HDFS_HOME=$HADOOP_HOME HADOOP_MAPRED_HOME=$HADOOP_HOME HADOOP_YARN_HOME=$HADOOP_HOME HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tool.jar:$JRE_HOME/lib:$HADOOP_HOME/lib export JAVA_HOME JRE_HOME PATH CLASSPATH
