下载 centos
[root@bogon soft]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/centos latest d123f4e55e12 7 days ago 196.6 MB
1.创建centos-ssh-root
1.1 创建 centos-ssh-root dockerfile
注意：
这里面 我们先安装 了 vim，本人喜欢vim,不喜欢vi
先安装which ,后面 hadoop format 需要用到
# 选择一个已有的os镜像作为基a础 FROM docker.io/centos # 镜像的作者 MAINTAINER baoyou curiousby # 安装openssh-server和sudo软件包，并且将sshd的UsePAM参数设置成no RUN yum install -y openssh-server sudo RUN sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config #安装openssh-clients RUN yum install -y openssh-clients RUN yum install -y vim RUN yum install -y which # 添加测试用户root，密码root，并且将此用户添加到sudoers里 RUN echo "root:root" | chpasswd RUN echo "root ALL=(ALL) ALL" >> /etc/sudoers # 下面这两句比较特殊，在centos6上必须要有，否则创建出来的容器sshd不能登录 RUN ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key RUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key # 启动sshd服务并且暴露22端口 RUN mkdir /var/run/sshd EXPOSE 22 CMD ["/usr/sbin/sshd", "-D"]

我这里已经存在 virbr0 ,没有virbr0就自己创建
brctl addbr virbr0 ip link set dev virbr0 up ip addr add 192.168.122.1/24 dev virbr0

出现以下 即分配ip成功
测试ssh 容器，成功
ssh hadoop0 ssh hadoop1 ssh hadoop2
3.8 修改 容器 hadoop0 hadoop1 hadoop2 内部hosts
本地 创建 sshhosts

copy 到 hadoop0,hadoop1,hadoop2
scp sshhosts root@hadoop0:/etc/hosts scp sshhosts root@hadoop1/etc/hosts scp sshhosts root@hadoop2/etc/hosts
3.9 容器内部ssh 免密钥
3.9.1 进入 hadoop0
docker exec -it hadoop0 bash
3.9.2 免密钥操作
在hadoop0上执行下面操作 cd ~ mkdir .ssh cd .ssh ssh-keygen -t rsa(一直按回车即可) ssh-copy-id -i localhost ssh-copy-id -i hadoop0 ssh-copy-id -i hadoop1 ssh-copy-id -i hadoop2 在hadoop1上执行下面操作 ssh hadoop1 cd ~ cd .ssh ssh-keygen -t rsa(一直按回车即可) ssh-copy-id -i localhost ssh-copy-id -i hadoop1 在hadoop2上执行下面操作 ssh hadoop2 cd ~ cd .ssh ssh-keygen -t rsa(一直按回车即可) ssh-copy-id -i localhost ssh-copy-id -i hadoop2
3.9.3 测试
在 hadoop0 中测试 ssh hadoop0 ,hadoop1,hadoop2
3.10 (重点) hadoop 配置
3.10.1 进入 hadoop 目录
cd /usr/local/hadoop/etc/hadoop/
