Build LAN Yum source + package extension + synchronous external network Yum source based on HTTP

1 Build LAN Yum Source (CENTOS7) 1.1 Yum Server install HTTP service based on HTTP

1) Install HTTP

Yum Install httpd httpd-devel–y

2) Start httpd service

Systemctl Restart Httpd.service

Setenforce 0 #关闭SELinux

Systemctl Stop Firewalld #临时停止防火墙

1.2 Yum server build LAN Yum source

1) Mount disc image file

Mount/dev/cdrom/mnt

2) Copy the CD package to the HTTP directory

Mkdir/var/www/html/centos7

Cp-r/mnt/packages/*/var/www/html/centos7/

3) Create a local source using Createrepo, generate the Repodata directory in the CENTOS7 directory

Yum Install createrepo*-y

cd/var/www/html/

Createrepo centos7/

1.3 Yum Client Create Http.repo file

1) Configure the repo file

cd/etc/yum.repos.d/

VI Http.repo

2) Clear Yum cache and install software test

Yum Clean All

Yum Install Ntpdate-y

2 Yum Source Package extensions

Packages that are not in the local disc image need to be added to the Yum server (the following is an example of the NTFS-3G package)

1) Download ntfs-3g package to/var/www/html/centos7

cd/var/www/html/centos7/

wget http://rpmfind.net/linux/epel/7/x86_64/Packages/n/ntfs-3g-2017.3.23-6.el7.x86_64.rpm

wget http://rpmfind.net/linux/epel/7/x86_64/Packages/n/ntfs-3g-devel-2017.3.23-6.el7.x86_64.rpm

2) Createrepo Command update package

Cd/var/www/html

Createrepo--update centos7/

3) Client Yum authentication Install NTFS-3G Package

Yum Install Ntfs-3g-y

3 Synchronous External Network Yum source

All packages from the Yum source can be synchronized locally to improve the number and completeness of the local Yum source packages

There are three common ways to get out of the network Yum source software: rsync, wget, Reposync

Rsync: Requires an extranet yum source to support the Rsync protocol

wget: Direct Access

Reposync: Can synchronize almost all Yum sources

The following is an example of reposync, synchronizing the external yum source software to a local

1) Yum server download Centos7 repo file to/etc/yum.repos.d/and install reposync command tool

cd/etc/yum.repos.d/

wget Http://mirrors.163.com/.help/CentOS7-Base-163.repo

MV Centos7-base-163.repo Centos.repo

Yum Clean All

Yum Install yum-utils createrepo-y

Yum Repolist All

2) through the Reposync command tool to obtain all packages of the extranet Yum source,-R to specify the Repolist ID, the default does not add-r means to get the extranet all Yum packages, the-p parameter indicates the path of the specified download package

Reposync-r base-p/var/www/html/centos7/

3) After downloading the package, you need to perform Createrepo update the local yum repository

createrepo/var/www/html/centos7/
