如果程序本身可以在前台运行，就不用写脚本，直接让在程序里启动
//制作镜像
[root@localhost ~]# docker commit -a 'sean <[email protected]>' -c 'CMD ["/usr/local/apache/bin/httpd","-D","FOREGROUND"]' -p c1 httpd:v0.4
[root@localhost ~]# docker run -d --name web1 -p 80:80 httpd:v0.4 //如果报错显示端口号被占
则把占用端口的那个删掉就行
[root@localhost ~]# docker rm -f web
//如果前面创建容器报错了端口被占，后面删除了占端口的web，run命令的创建成功了，启动没有成功，所以需要启动
[root@localhost ~]# docker start web1
