Nexus-Configuration-Ubuntu-Apt-Source

利用Nexus做Ubuntu私有源

1、创建独立存储

1.1、创建目录

登录进来后首先先创建一个独立的目录在服务器上用于存放apt相关的缓存

root@k8s-master01:~# mkdir  /data/nexus/apt -p
root@k8s-master01:~# ll /data/nexus/
drwxr-xr-x 4 root root 4096 Oct  3 19:58 apt

1.2、设置路径

所用到的目录创建好后在Nexus控制台上配置出目录名称

配置目录

1.3、配置代理仓库

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：代理仓库，它们被用来代理远程的公共仓库，如maven 中央仓库(官方仓库)。
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。

选择apt-proxy模式

配置相关参数

完成设置

1.4、验证

配置完后找一台ubuntu的机器来修改apt源的走向

root@k8s-master-12:~# cd /etc/apt/
# 查看当前apt源地址。当前配置的是华为云的apt地址
root@k8s-master-12:/etc/apt# cat sources.list
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://repo.huaweicloud.com/ubuntu focal main restricted
# deb-src http://repo.huaweicloud.com/ubuntu focal main restricted

## Major bug fix updates produced after the final release of the
## distribution.
deb http://repo.huaweicloud.com/ubuntu focal-updates main restricted
...
# 使用sed修改
root@k8s-master-12:/etc/apt# sed -i 's#http://repo.huaweicloud.com/ubuntu#http://172.20.21.11:8081/repository/ubuntu-focal/#g' sources.list
# 查看修改后的地址
root@k8s-master-12:/etc/apt# cat sources.list
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://172.20.21.11:8081/repository/ubuntu-focal/ focal main restricted
# deb-src http://172.20.21.11:8081/repository/ubuntu-focal/ focal main restricted

## Major bug fix updates produced after the final release of the
## distribution.
deb http://172.20.21.11:8081/repository/ubuntu-focal/ focal-updates main restricted
# deb-src http://172.20.21.11:8081/repository/ubuntu-focal/ focal-updates main restricted
...

修改好源后使用apt update更新下源

至此在Nexus下配置Ubuntu私有源结束。Nexus还可以配置其他的源。其他的就不一一去验证了。
