Publish Yum private server using nexus3 (offline intranet)

The company's servers are not networked , The company requires the intranet to be built yum Private clothes

I found that this part is rarely found in online tutorials , I hope this article can help you

First of all, you should build it correctly nexus3, I use docker Built , You can baidu by yourself or refer to the connection I wrote  docker install nexus3 （ offline / Intranet ）_zk_Kang The blog of -CSDN Blog ,

Relatively simple , Image download , Mapping directory , To start, etc.

Let me start with my thoughts ,

1. The Intranet environment is installed nexus3- Use docker, Remember to map directories , If you are linux, That's easy , Just look at the directory you installed .

2. After installation nexus3 Created on yum Environmental Science --yum Kuhe yum source address .

3. Download the image source package from a machine with an external network environment

4. Import the downloaded image source package to the intranet

5. Import the image source package in batches to nexus3 Upper yum Source address

Install as follows -- Note that the one in the red box is built by myself  

1. Create a library （ If you want to use default, This step can be omitted , Look directly at step two ）

as follows - Click on create blob store 

The latest version I use , It's changed here. You need to choose here type by file, If you don't have this , It doesn't matter , To look down .

  Define the library name as yum-hub

After creation, you can see , Here you are size Should be 0, I put something in it, so size Not for 0

 2. establish yum Mirror source

Here you are proxy（ agent ） hosted（ Local mirror source ）group（proxy and hosted The combination of ）

You can only create hosted and group , You can also create just one hosted（ Anyway, you have no Internet , One is enough , Of course, in case of subsequent expansion of the local image source , It is suggested to establish a group, Will all hosted Put in group）

Here is a demonstration of proxy It also demonstrates ,-- If you have Internet conditions in this step, you can take a look

1. spot create repository 

2. establish proxy agent

Below http://url, Just write an Alibaba image source

 3.hosted- Local mirror source

  I circled all the important places with red boxes ,

Here we need to pay attention to the following allow redeplov, The meaning of contract awarding can be repeated here

 4. Build a group

hold proxy（ agent ） hosted（ Local mirror source ） All joined group

Remember   hosted（ Local mirror source ） On, ha , If you are an intranet, there is no proxy 了 , There is no need to establish , Not to mention .

Who's on , Who are you looking for first , I found it locally , Don't download , This is the role of private servers , Save bandwidth .

LAN downloads are faster than networking

5. After the foundation of

Now ,yum It's empty

 3. Download Image Source

Machine with internet , I was in liunx Operated on the machine .

For details, please refer to this blog written by this blogger , I downloaded it according to what he wrote .  I didn't install all his downloads , I downloaded a base library

Centos7 Build your own private yum Mirror source _Halyace The blog of -CSDN Blog _ private yum Source

#  Download Alibaba image source 
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
#  Download Ali epel Source 
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
#  Delete cache 
yum clean all
#  Update cache 
yum makecache
#  View the list of image sources 
yum repolist
#  Install the synchronization tool 
yum install -y yum-utils 
#  install repo Production tools 
yum install -y createrepo
#  install wget
yum install -y wget

#  Create directory 
mkdir -p /home/repos_local/centos/7
#  Sync 
reposync -r base -p /home/repos_local/centos/7
#  establish repo data 
createrepo /home/repos_local/centos/7/base

I'll be done here , Put... Directly /home/repos_local This package can be delivered to the intranet . I'm going to home Give orders .

Compress command ：tar -cvf xx.tar.gz repos_local

4. Batch upload to intranet server

First turn on the decompression

tar -zxvf xx.tar.gz

After decompression, enter the directory and directly execute the command ,      Copy all , Direct execution , You may write a document , Perform the same , I compare lazy , I will directly execute . Remember *** For your password , hinder ip The address has to be changed .

The directory hierarchy here , You can define yourself , I also defined myself .

#! /bin/bash
for i in `ls /home/repos_local/CentOS7/base/Packages`;
do curl -v --user 'admin:***' --upload-file /home/repos_local/CentOS7/base/Packages/$i http://ip:8081/repository/yum/CentOS7/base/Packages/$i;
done

When you're done, you can yum-hosted Next, I see what you uploaded rpm It's packed

5. Use yum Private clothes

All the previous work is for this step

Get into /etc/yum.repos.d Under the table of contents ,

If there is a suffix in this directory repo The file of , Build a mkdir bak Put... In this directory repo File move to bak Under the table of contents

stay /etc/yum.repos.d Create a new one in the directory repo file , Name at will

vi centos.repo

The contents are as follows , Here I see some places that write base, But through my actual discovery, I wrote base layer yum Can not use , If this happens to you , You can write first base layer , hinder Packages, If not , Re reform .

My address here is yum Of group route

#  Unnecessary warehouses can be commented out 
#  All intranet warehouses are closed gpgcheck check 
# base Warehouse 
[base]
name=Local CentOS-7  Base
baseurl=http://xxx:8081/repository/yum-group/CentOS7/base/Packages/
enabled=1
gpgcheck=0

After writing , You can use it

Test it , The following two clear the cache , Let the new yum Download from the new configuration .

yum clean all

yum makecache

# Test a download

yum -y install httpd 

That's it , I hope this article can help you .

yum repolist-- Execute this command , Check your image source
