docker安裝

安裝

yum install -y epel-releas
yum install docker-io

加入開機啟動

chkconfig docker on

啟動docker

service docker start

拉取基礎鏡像 centos

centos鏡像

sudo docker pull insaneworks/centos

制作Hadoop鏡像

進入centos容器

sudo docker run -it -h master --name master insaneworks/centos /bin/bash

裝gcc

yum install -y gcc

裝vim

yum install -y vim

裝lrzsz

yum install -y lrzsz

裝ssh

yum -y install openssh-server

yum -y install openssh-clients

修改ssh配置

vim /etc/ssh/sshd_config

放開 PermitEmptyPasswords no

更改 UsePAM no

放開 PermitRootLogin yes

啟動sshd

service sshd start

ssh密碼設置

ssh-keygen -t rsa -P "" -f ~/.ssh/id_dsa

cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

ssh連master

ssh master    

安裝java

在docker容器中安裝Java（從宿主機向docker容器中拷貝文件）

安裝tar

yum install -y tar

下載Hadoop

http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.8.2/hadoop-2.8.2.tar.gz    

tar.gz是已經編譯好的了，解壓改改配置文件就能用。src.tar.gz是源碼，要編譯才能用。tar.gz的是給32位機器用的，想在64位機器上用只能用編譯的。

解壓

tar zxvf hadoop-2.8.2.tar.gz

配置環境變量

export HADOOP_HOME=/home/hadoop/hadoop-2.8.2
export PATH=$JAVAHOME/bin:$HADOOP_HOME/bin:$PATH

在hadoop-env.sh 和 yarn-env.sh中添加環境變量

vim hadoop-env.sh
vim yarn-env.sh

添加環境變量
export JAVA_HOME=/usr/java/jdk1.7.0_75

修改 hadoop core-site.xml

fs.defaultFS
hdfs://master:9000


io.file.buffer.size
131702


hadoop.tmp.dir
file:/mnt/hadoop-2.8.2/tmp

   

修改hdfs-site.xml

dfs.namenode.name.dir
file:/mnt/hadoop-2.8.2/dfs/name


dfs.datanode.data.dir
file:/mnt/hadoop-2.8.2/dfs/data


dfs.replication
2


dfs.namenode.secondary.http-address
master:9001


dfs.webhdfs.enabled
true

修改mapred-site.xml文件

mapreduce.framework.name
yarn


mapreduce.jobhistory.address
master:10020


mapreduce.jobhistory.webapp.address
master:19888

修改yarn-site.xml

yarn.nodemanager.aux-services
mapreduce_shuffle


yarn.nodemanager.auxservices.mapreduce.shuffle.class
org.apache.hadoop.mapred.ShuffleHandler


yarn.resourcemanager.address
master:8032


yarn.resourcemanager.scheduler.address
master:8030


yarn.resourcemanager.resource-tracker.address
master:8031


yarn.resourcemanager.admin.address
master:8033


yarn.resourcemanager.webapp.address
master:8088


yarn.nodemanager.resource.memory-mb
1024

在slaves文件中添加

slave1
slave2
slave3

ldd

yum install -y wget

wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz

tar zxvf glibc-2.14.tar.gz

cd glibc-2.14

mkdir build

cd build

../configure --prefix=/usr/local/glibc-2.14

make

make install

ln -sf /usr/local/glibc-2.14/lib/libc-2.14.so /lib64/libc.so.6

ldd /home/hadoop/hadoop-2.6.0/lib/native/libhadoop.so.1.0.0

commit鏡像

docker commit master hadoop

啟動hadoop集群

docker rm master

sudo docker run -it -p 50070:50070 -p 19888:19888 -p 8088:8088 -h master --name master hadoop /bin/bash

sudo docker run -it -h slave1 --name slave1 hadoop /bin/bash

sudo docker run -it -h slave2 --name slave2 hadoop /bin/bash

sudo docker run -it -h slave3 --name slave3 hadoop /bin/bash
    

進入到每個節點執行

source /etc/profile

service sshd start

每個節點配置hosts

查看IP地址
docker inspect --format="{{.NetworkSettings.IPAddress}}" master

配置hosts
172.42.0.42 master

172.42.0.46  slave1

172.42.0.47  slave2

172.42.0.48  slave3

啟動hadoop

./sbin/start-all.sh

查看
