在生产环境中，咱们总会遇到下载或更新rpm包的操做，可是每每咱们不可能全部的服务器都能链接外网（特别是一些zf单位）。因此理想的状况下就是咱们有一台linux服务器能够连外网，其他的服务器经过它作代理来更新rpm包。java

有一些比较传统的方法是把包下载到本地，经过createrepo命令生成本地仓库，其他的服务器经过ftp/http的方式来访问，可是有时候咱们会须要一些拓展的包，因此有没有一种比较方便的方式让咱们能够代理到阿里或者163的yum源呢。linux

下面咱们就讲一下使用Nexus代理，无论是你是centos6,centos7或者ubuntu，也无论你是rpm仍是pip或是yum，Nexus均可以知足你的需求。apache

安装：ubuntu

操做系统：centos7centos

[root@yangdong ~]# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core)

nexusServer:　　192.168.105.233缓存

安装前的准备：关闭selinux，安装jdk,安装maven服务器

# sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/configcurl

# java -version
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)maven

# mvn -v
Apache Maven 3.6.1 (d66c9c0b3152b2e69ee9bac180bb8fcc8e6af555; 2019-04-05T03:00:29+08:00)
Maven home: /opt/apache-maven-3.6.1
Java version: 1.8.0_151, vendor: Oracle Corporation, runtime: /opt/jdk1.8.0_151/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-327.el7.x86_64", arch: "amd64", family: "unix"ui

环境配置：

export JAVA_HOME=/opt/jdk1.8.0_151
export PATH=$PATH:$JAVA_HOME/bin
export PATH=$PATH:/opt/apache-maven-3.6.1/bin

安装Nexus:

[root@yangdong opt]# tar xf latest-unix.tar.gz  #会生成 nexus-3.18.1-01  sonatype-work两个目录
[root@yangdong opt]# ls
apache-maven-3.6.1             jdk1.8.0_151                latest-unix.tar.gz  sonatype-work
apache-maven-3.6.1-bin.tar.gz  jdk-8u151-linux-x64.tar.gz  nexus-3.18.1-01

启动Nexus:

[root@yangdong opt]# cd nexus-3.18.1-01/bin/
[root@yangdong bin]# ./nexus start
WARNING: ************************************************************
WARNING: Detected execution as "root" user.  This is NOT recommended!
WARNING: ************************************************************

　[root@yangdong nexus-3.18.1-01]# ./bin/nexus status
　WARNING: ************************************************************
　WARNING: Detected execution as "root" user. This is NOT recommended!
　WARNING: ************************************************************
　nexus is running.

配置Nexus:

访问地址：http://192.168.105.233:8081

初始用户：admin 密码：cat /opt/sonatype-work/nexus3/admin.password

创建仓库：

这个时候咱们就已经部署好了，只须要在客户端配置repo文件就能够了。

#yum clean all
#yum makecache
[root@yangdong ~]# cd /etc/yum.repos.d/
[root@yangdong yum.repos.d]# ls
nexus.repo  repot
[root@yangdong yum.repos.d]# cat nexus.repo 
[nexus]

name=Nexus Yum Repository

baseurl=http://192.168.105.233:8081/repository/yumGroup/$releasever/os/$basearch/

enabled=1

gpgcheck=0

这个时候你可能会报错：

[root@yangdong yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
Determining fastest mirrors
http://192.168.105.233:8081/repository/yumGroup/7/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 401 - Unauthorized
Trying other mirror.

是由于你是匿名用户访问Nexus,所以认证不经过。须要打开匿名用户的权限。

这时候咱们下载一个包试试：

[root@yangdong yum.repos.d]# yum repolist

能够看到咱们的仓库已经识别到了Nexus，同时咱们下载了httpd的包。这时候咱们去Nexus上看下是否缓存了。

能够看到咱们的Nexus已经缓存到了本地，下载在有客户端如今httpd就能够直接从Nexus获取了。

同时，Nexus也可作maven的缓存，这个后期有须要的时候会继续更新！

#批量上传本地的rpm包：

for i in `ls /var/centos6`; do curl -v --user 'admin:admin123' --upload-file $i http://192.168.105.233:8081/repository/yumDev/$i; done
