Local Yum source production

Preface ：

         Usually use windows We will save the commonly used software packages to our own computers , For subsequent offline installation , that linux If the system is not connected to the Internet , How do we install it , At this time, it is necessary to conduct local networking in advance yum Source production .

        Like the installation package of ordinary software products , Will package the dependent packages involved offline to the installation package , For customers to install offline .

        Let's make a git Take the offline source of .

        （ One ） Download offline rpm

        （ Two ） Make offline source

        （ 3、 ... and ） Use offline source

（ One ） Download offline rpm

1. On a computer that can be connected to the Internet centos Operate on the machine , Guarantee /etc/yum.repo.d/ There is only one repo file （ One is reserved here so that you can quickly find the corresponding download after subsequent installation rpm package ！！）

2. We need to configure yum file , Set up install When installing, it will automatically rpm Save the package locally

# vim /etc/yum.conf

keepcache=1（0： Do not download | 1： Download to local ）, Need to change to 1

3. Once you set it up , We perform the installation .（ Here we need to make the offline source of the service ,install Just install one , It doesn't matter if you can install more than one at the same time , There's no limit to the number ！！）

# yum -y install git

We can see that a total of 4 individual rpm package . 

4. After installation , Let's go down this path , You can see that install Installed rpm Packages are saved to this directory .

# cd /var/cache/yum/x86_64/7

according to repo File name find the corresponding folder , We can see the newly downloaded and installed 4 individual rpm It has been cached locally on the server .

5. We will packages Under the rpm The packages are copied to any empty folder （ for example ： /root/git/packages/）

（ Two ） Make offline source

1. install createrepo

# rpm -ivh createrepo-0.9.9-26.el7.noarch.rpm deltarpm-3.6-3.el7.x86_64.rpm python-deltarpm-3.6-3.el7.x86_64.rpm

  These depend on the download path of the package ：https://pan.baidu.com/s/1jl1bYR8hB6L8ruGW-bxQrA 
  Extraction code ：6ev3

2. Generate repodata file

# createrepo /root/git/packages/                            Replace the path with the new one rpm The catalog of

# yum makecache

After production ,packages A... Will be generated in the directory repodata The catalog of . We can git The catalog is packaged as a whole , Subsequent machines can be directly copied and decompressed .

  So far our git After the offline source is made .

（ 3、 ... and ） Use offline source

ssh Connect to an Internet connection centos On the machine , Will just make a good git/ Copy directory to /tmp Under the table of contents .

1. Get into /etc/yum.repo.d/ Under the table of contents , To configure git.repo file

[git]
