大流量网站 优化,建房的网站,广东旅游网站建设,建立一个公司网站1、基础镜像ubuntu:18.04 2、替换为国内的安装源 3、安装openssh-server 4、允许root用户远程登陆 5、暴露端口22 6、服务开机自启动 1.创建目录
[rootopenEuler-node1 db]# mkdir sshd_ubuntu
2.创建 Dockerfile、 run.sh 、authorized_keys、vim aliyun.list 文件

[rootopenEuler-node1 db]# mkdir sshd_ubuntu
2.创建 Dockerfile、 run.sh 、authorized_keys、vim aliyun.list 文件
[rootopenEuler-node1 sshd_ubuntu]# cd sshd_ubuntu
[rootopenEuler-node1 sshd_ubuntu]# touch Dockerfile run.sh authorized_keys vim aliyun.list
3.在宿主主机上生成 SSH 密钥对,写入authorized_keys
[rootopenEuler-node1 ~]# ssh-keygen -t rsa
[rootopenEuler-node1 sshd_ubuntu]# cd sshd_ubuntu
[rootopenEuler-node1 sshd_ubuntu]# cat ~/.ssh/id_rsa.pub authorized_keys 4.编写更改Ubuntu的源为国内aliyun源
[rootopenEuler-node1 sshd_ubuntu]# vim aliyun.list
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
5.编写run.sh
#!/bin/bash
/usr/sbin/sshd -D5.编写 Dockerfile
[rootopenEuler-node1 sshd_ubuntu]# vim Dockerfile FROM ubuntu:18.04
MAINTAINER yujyjqq.comCOPY aliyun.list /etc/apt/sources.list.d/aliyun.list
RUN apt update \apt install -y openssh-server \mkdir /var/run/sshd \sed -ri s/session required pam_loginuid.so/#session required pam_loginuid.so/g /etc/pam.d/sshd \mkdir /root/.ssh
COPY authorized_keys /root/.ssh/
COPY run.sh /run.sh
RUN chmod 755 /run.shEXPOSE 22
CMD [/run.sh]6.制作镜像并启动容器
[rootopenEuler-node1 sshd_ubuntu]# docker build -t sshd:ubuntu_v1 ./
[rootopenEuler-node1 sshd_ubuntu]# docker run -d -P sshd:ubuntu_v1
7.查看容器运行状态
[rootopenEuler-node1 sshd_ubuntu]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
