企业内部从零开始安装docker hadoop 提纲

下载apache 项目 http://mirror.bit.edu.cn/apache/
下载 centos 7 安装 盘 iso 大约7G

安装 centos7

copy 光盘盘中的 packages repodata 到硬盘

建立 httpd 服务修改 /etc/httpd/conf/httpd.conf 中的 docmentroot ??

service httpd start .

如果有selinux 注意semanage chcon restorecon 命令 保持 与 /var/www 一致的上下文 ,使用 ls -Z 查看

web网站建立后

编写 /etc/yum.repo.d 中的 文件 ,

测试 yum 命令 : yum clean all ;yum makecache

如果有新的 rpm 也可放到 package目录 不过要使用 createrepo 重新建立 索引数据库

下载 docker 1.9

使用 rpm 安装

测试 service docker start

到 csphere 下载 安装 分析安装sh(找一个centos虚拟机在互联网上安装 然后 使用 docker save ;docker load 装载到企业本地) 主要管理docker 方便

使用网上的一个脚本建立 centos 的docker image https://raw.githubusercontent.com/docker/docker/master/contrib/mkimage-yum.sh

起名 centos

基于centos ,建立 jdk8 sshd 起名 jdk8:centos7

from centos7:7.2.1511

Add jdk-8u65-linux-x64.gz /usr/sbin
env JAVA_HOME  /usr/sbin/jdk1.8.0_65
env CLASSPATH   /usr/sbin/jdk1.8.0_65/lib/dt.jar:/usr/sbin/jdk1.8.0_65/lib/tool.jar

run echo   "JAVA_HOME=$JAVA_HOME;export JAVA_HOME;" >>/etc/profile
run echo   "CLASSPATH=$CLASSPATH:$JAVA_HOME;export CLASSPATH;" >>/etc/profile
run  echo  "PATH=$PATH:$JAVA_HOME/bin;export  PATH ;">>/etc/profile
run  echo  "PATH=$PATH:$JAVA_HOME/bin;export  PATH ;">>/etc/bashrc
run rm -f /etc/yum.repos.d/Cent*
add   yum.repo /etc/yum.repos.d
run systemctl enable sshd.service
run /usr/lib/systemd/systemd --system &
run yum -y install which  openssl sshd wget net-tools openssh-client openssh-server
run ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N ""
run ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N ""
run ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N ""
run ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key -N ""
run     /usr/sbin/sshd
run echo root | passwd root --stdin
run yum makecache &&yum clean all
run   ssh-keygen -t rsa -f ~/.ssh/id_rsa -N "";  cat ~/.ssh/id_rsa.pub >>~/.ssh/authorized_keys
run echo "StrictHostKeyChecking no " >>~/.ssh/config

Entrypoint   /usr/sbin/sshd;/bin/bash

[local]
name=local
baseurl=http://XXX.XXX/yum
enable=1
gpgcheck=0

yum.repo

基于jdk8:centos7 建立 hadoop2.6

from jdk8:centos7

Add  hadoop-2.6.2.tar.gz  /home/

run ln -s /home/hadoop-2.6.2/ /home/hadoop   && cd /home/hadoop

workdir /home/hadoop
expose 22 50070
copy etc  /home/hadoop/etc/hadoop

run  echo  "export PATH=$PATH:$JAVA_HOME/bin:/home/hadoop/sbin:/home/hadoop/bin;">>/etc/profile
run  echo  "export PATH=$PATH:$JAVA_HOME/bin:/home/hadoop/sbin:/home/hadoop/bin;" >>/etc/bashrc
run systemctl enable sshd.service
run /usr/lib/systemd/systemd --system &

copy hadoop-config.sh  /home/hadoop/libexec
Entrypoint  /usr/sbin/sshd;/bin/bash

测试 单节点hadoop 能否启动 (出现java没找到 ,手工修改 /libexec 中的 hadoop-config.sh )

start-dfs.sh start-yarn.sh

zoo image 的 dockerfile

from hadoop
Add  zookeeper-3.4.7.tar.gz /home/
EXPOSE 16020 16202 16010 60000 60010 22 7373 7946 9000 50010 50020 50070 50075 50090 50475 8030 8031 8032 8033 8040 8042 8060 8088 50060 2888 2181 3888 8480 10020 19888

volume /data/hadoop

copy  ha_etc/slaves_datanode.txt  /home/hadoop/etc/hadoop/slaves
run mkdir /home/zookeeper-3.4.7/data
env   HA_ID rm1

Add hbase-1.0.2-bin.tar.gz   /home/
run sed -i "s/# export JAVA_HOME=\/usr\/java\/jdk1.6.0\//export JAVA_HOME=\/usr\/sbin\/jdk1.8.0_65/g"  /home/hbase-1.0.2/conf/hbase-env.sh

run echo "export HBASE_MANAGES_ZK=false" >>/etc/bashrc
Entrypoint  /usr/sbin/sshd;/bin/bash
