2.8创建html目录并下载可道云

2.11测试

2.12编写启动脚本（夯住起动命令在最后一个启动）

vi init.sh#!/bin/bashservice php-fpm startnginx -g 'daemon off;'~                     

2.13生成镜像

[root@docker03 /etc/nginx]# docker commit 274ca61dd89f docker_kod:v1sha256:da72ea94c8cbf9f2c21b7655b4146b0308053c3988fc2b6d165a1f6dd4cbc8de

2.14测试镜像

[root@docker03 ~]# docker run  -d -p 81:80 docker_kod:v1 /bin/bash /init.shcd5d18b69f1438426da1283160c73cbe45c2d8f73e74f5adeec0211bf14b52b7

3.docker手动制作镜像(基于C7)（Nginx+ssh）

3.1.创建并进入容器

[root@docker03 ~]# docker run -it -p 83:80 centos:7[root@c919e69954a2 /]# 

3.2.更改容器系统的yum源和epel源

[root@c919e69954a2 /]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo100  2523  100  2523    0     0  17831      0 --:--:-- --:--:-- --:--:-- 17893[root@c919e69954a2 /]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed100   664  100   664    0     0   5044      0 --:--:-- --:--:-- --:--:--  5068

3.3.安装nginx

[root@c919e69954a2 /]# yum install nginx -y

3.4.启动服务

注：C7在容器中无法使用systemctl启动服务，因为bus进程没有启动，C7启动快是因为多个进程同时启动。

root@docker03 ~]# ps -ef |grep busdbus       6819      1  0 Dec12 ?        00:00:03 /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activationroot      43281  40267  0 11:09 pts/1    00:00:00 grep --color=auto bus[root@c919e69954a2 /]# systemctl start nginxFailed to get D-Bus connection: Operation not permitted

用手动启动服务

[root@c919e69954a2 /]# systemctl start nginxFailed to get D-Bus connection: Operation not permitted[root@c919e69954a2 /]# systemctl cat nginx# /usr/lib/systemd/system/nginx.service[Unit]Description=The nginx HTTP and reverse proxy serverAfter=network.target remote-fs.target nss-lookup.target[Service]Type=forkingPIDFile=/run/nginx.pid# Nginx will fail to start if /run/nginx.pid already exists but has the wrong# SELinux context.

3.5.安装ssh服务

[root@c919e69954a2 /]# yum install openssh-server -y

3.6启动sshd-keygen服务（因为没有密钥对，报错）

[root@c919e69954a2 /]# /usr/sbin/sshd-keygen/usr/sbin/sshd-keygen: line 10: /etc/rc.d/init.d/functions: No such file or directoryGenerating SSH2 RSA host key: /usr/sbin/sshd-keygen: line 63: success: command not foundGenerating SSH2 ECDSA host key: /usr/sbin/sshd-keygen: line 105: success: command not foundGenerating SSH2 ED25519 host key: /usr/sbin/sshd-keygen: line 126: success: command not found

3.7在宿主机查询文件对应的软件包

[root@docker01 ~]# rpm -qf /etc/rc.d/init.d/functionsinitscripts-9.49.46-1.el7.x86_64

3.8安装软件包

[root@c919e69954a2 /]# yum install initscripts  -y

3.9在启动sshd-keygen服务,查看秘钥对

[root@c1e50af6f42c /]# /usr/sbin/sshd-keygenGenerating SSH2 RSA host key:                              [  OK  ]Generating SSH2 ECDSA host key:                            [  OK  ]Generating SSH2 ED25519 host key:                          [  OK  ][root@c919e69954a2 /]# ls /etc/ssh/moduli                    ssh_host_ecdsa_key.pub    ssh_host_ed25519_key.pub  ssh_host_rsa_key.pub      ssh_host_ecdsa_key        ssh_host_ed25519_key      ssh_host_rsa_key          sshd_config       

3.10启动sshd服务

[root@c919e69954a2 /]# systemctl cat sshd# /usr/lib/systemd/system/sshd.service[Unit]Description=OpenSSH server daemonDocumentation=man:sshd(8) man:sshd_config(5)After=network.target sshd-keygen.serviceWants=sshd-keygen.service[Service]Type=notifyEnvironmentFile=/etc/sysconfig/sshdExecStart=/usr/sbin/sshd -D $OPTIONSExecReload=/bin/kill -HUP $MAINPIDKillMode=processRestart=on-failureRestartSec=42s[Install]WantedBy=multi-user.target[root@c919e69954a2 /]# /usr/sbin/sshd -D

3.11设置容器登录密码

echo '123456' | passwd  --stdin root

3.12连接测试
