基础环境要求
内外网centos 服务器
nexus服务器配置阿里yum源
sh> mkdir /etc/yum.repo.d/bak
sh> mv /etc/yum.repo.d/*.repo /etc/yum.repo.d/bak
下载阿里yum源文件
sh> wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
或手动配置阿里yum源
sh> vim Centos-base.repo
粘贴以下阿里云yum源

安装docker
关闭防火墙配置命令
sh> setenforce 0
sh> sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/config
下载安装docker
sh> yum install -y docker
sh> systemctl start docker
sh> systemctl enable docker
docker下载安装nexus
sh> docker pull sonatype/nexus3
查看docker镜像
sh> docker images
新建nexus 数据目录
sh> mkdir /home/data/nexus-data
启动nexus 容器
sh> docker run -d --name nexus --net=bridge --ulimit nofile=65536:65536 -p 8081:8081 -p 8082:8082 -p 8083:8083 -p 8084:8084 -v /home/data/nexus-data:/nexus-data sonatype/nexus3 sonatype/nexus3
检查docker容器是否启动
sh> docker ps -a
浏览器访问nexus控制台 http://192.168.134.249:8081/
账号：admin 密码查看：
sh> cat /home/data/nexus-data/admin.password 进入控制台后，要修改密码
yum仓库搭建
账号密码登录后，进入配置，入口如下
创建存储空间
命名：yum-blo
b 类型：File
创建本地yum repository
选择yum-hosted
名称：yum-local，如图选择对应的选项，storage 选择 yum-blob
提交保存
创建代理yum repository
选择yum-proxy填写name：yum-proxy，url：http://mirrors.163.com/centos/
提交保存
创建组合 yum repository
选择yum-group填写name：yum-group，添加上面两个仓库
复制yum-group仓库地址
连接nexus 源服务器配置
sh> mkdir /etc/yum.repo.d/baksh> mv /etc/yum.repo.d/*.repo /etc/yum.repo.d/bak
sh> vim Centos-base.repo编辑以下nexus yum源，注意替换成上面的yum-group地址
[base]

搭建apt代理
后台管理配置
进入后台管理，创建入口如下：
选择apt(proxy)
Name: apt-proxy
Distribution: bionic
Remote storage: https://mirrors.aliyun.com/ubuntu/
Blob store: apt-clob (说明：任意选择一个，因为代理不会存储数据，没有的选，可以自己创建一个，参考“yum 创建存储空间步骤”)点击保存完成
apt客户端配置
sh> mv /etc/apt/sources.list /etc/apt/sources.list.oldsh> vim /etc/apt/sources.list拷贝以下内容：
deb http://192.168.134.249:8081/repository/apt-proxy/ bionic main restricted universe multiverse
deb http://192.168.134.249:8081/repository/apt-proxy/ bionic-security main restricted universe multiverse
