Yum Benefits: Yum installs software that easily resolves dependency issues

Experiment: Make a yum warehouse, now has two servers CENTOS6 (abbreviated 6), CENTOS7 (abbreviated 7), I use 7 as a data source, with native or CENTOS6 access how to configure the warehouse

Mount Disc Method:

1. I can mount the 6,7 disc at the same time on 7,
   

   Hang up after: read out 2 disks, if there is no echo '---' >/sys/class/scsi_host/host2/scan
   

   Ok

2. /var/ftp/pub mkdir centos/6/os/x86_64/-PV Create a table of contents

3. mount/dev/sr0 centos/6/os/x86_64/mount file Of course, this DEV/SR0 disc is also 6.

See if the/var/ftp/pub/centos/6/os/x86_64 has been mounted successfully

#===================================

Configure a warehouse source

#网络光盘仓库配置源
[Base2]
Name=ftp centos7.4
baseurl=ftp://ip/pub/centos/$releasever/os/$basearch/
Gpgcheck=0
#enabled =0

Yum repolist View--OK

The above data source and warehouse source are configured

Check:

Turn off SELinux
Sed-i.bak ' s/selinux=enforcing/selinux=permissive/'/etc/selinux/config
Setenforce 0
Close Iptables

Shutting down the firewall

Centos7
Systemctl Stop Firewalld

Start the FTP service: (CENTOS7)

Systemctl start vsftpd now start
Systemctl Enable VSFTPD Auto-start on next boot

Start the FTP service: (CENTOS6)

Service VSFTPD Start

Okay, configure the warehouse data on 6: You can access the

Testing the Yum Warehouse

If the developer's own packages are put into the app to create a Yum repository source.
mkdir app
Randomly simulate a package to a CentOS 6 copy
Cp/var/ftp/pub/centos/6/os/x86_64/packages/tree-1.5.3-3.el6.x86_64.rpm/var/ftp/pub/app
Making the source data for the Yum repository

If there is an increase in the package, first delete the previous source data before adding a package
