vi init.sh
#!/bin/bash
service php-fpm start
nginx -g 'daemon off;'
~ 2.13生成镜像
[root@docker03 /etc/nginx]# docker commit 274ca61dd89f docker_kod:v1

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 /]# yum install nginx -y3.4.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 bus
