验证默认仓库：
Hosted：
Hosted：本地仓库，通常我们会部署自己的构件到这一类型的仓库，比如公司的第三方库
Proxy
Proxy：代理仓库，它们被用来代理远程的公共仓库，如 maven *仓库(官方仓
库)。
Group：
Group：仓库组，用来合并多个 hosted/proxy 仓库，当你的项目希望在多个
repository 使用资源时就不需要多次引用了，只需要引用一个 group 即可。
创建目录
[root@mq-node3 ~]# mkdir /data/nexus/epel -p
用到再把路径复制出来
范例；配置CentOS7-epel源
[root@localhost yum.repos.d]# vim nexus-epel.repo
[epel-nexus]
name=nexus-epel
baseurl=http://172.31.2.46:8081/repository/epel-nexus/
gpgcheck=0
enabled=1
查看
[root@localhost yum.repos.d]# yum repolist
范例：Ubuntu1804源
创建目录
[root@mq-node3 ~]# mkdir /data/nexus/ubuntu1804 -p
修改apt源配置
[root@Bj-Ubuntu ~]# vim /etc/apt/sources.list
deb http://172.31.2.46:8081/repository/ubuntu1804-nexus/ bionic main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
