[root@docker_registry ~]# rpm -ql docker-distribution
/etc/docker-distribution/registry/config.yml
/usr/bin/registry
/usr/lib/systemd/system/docker-distribution.service
/usr/share/doc/docker-distribution-2.6.2
/usr/share/doc/docker-distribution-2.6.2/AUTHORS
/usr/share/doc/docker-distribution-2.6.2/CONTRIBUTING.md
/usr/share/doc/docker-distribution-2.6.2/LICENSE
/usr/share/doc/docker-distribution-2.6.2/MAINTAINERS
/usr/share/doc/docker-distribution-2.6.2/README.md
/var/lib/registry
[root@docker_registry ~]#

　　提示：/etc/docker-distribution/registry/config.yml这个文件用于配置registry的配置文件；/usr/bin/registry是二进制应用程序；/usr/lib/systemd/system/docker-distribution.service 这个文件是docker-distribution的unit file；/var/lib/registry这个目录用于存放我们上传到registry上的镜像存放地；

　　4、查看配置文件

[root@docker_registry ~]# cat /etc/docker-distribution/registry/config.yml
version: 0.1
log:
  fields:
    service: registry
storage:
    cache:
        layerinfo: inmemory
    filesystem:
        rootdirectory: /var/lib/registry
http:
    addr: :5000
[root@docker_registry ~]#

　　提示：这个配置文件是一个yml语法的配置文件，从上面的信息可以看到，默认情况docker-distribution监听在tcp的5000端口；存放镜像的目录是/var/lib/registry/目录下；

　　5、启动docker-distribution
