Redhat7.4 configure Yum software warehouse (rhel7.4)

yum Software warehouse

Yum The role of the warehouse is to further simplify RPM(redhat package manager)  The difficulty of managing software and the technology of automatically analyzing the required software packages and their dependencies

Build and configure Yum The general steps of software warehouse are as follows （RHEL7.4 Version as an example ）

Experiment preparation （ The following experiments are VMware In the middle of ）

1、 a rhel7.4 host （ It's online ）

2、 I choose graphical installation here

Be careful ： If you are

Minimize installation

Words , Then please send the following commands ==vim== Change it to ==vi== Because of the small installation rhel yes

Out-of-service vim Editor

Of ,

Only use vi

Only when it's ready yum After the software warehouse   function ：

yum install vim -y

  Install one of your own

1、 Mount the CD image

Turn on virtual machine settings

Mount the image （ This image is the CD image ）

A CD will appear on the desktop

2、 see

[[email protected] ~]# lsblk 
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 20G 0 disk 
├─sda1 8:1 0 1G 0 part /boot
└─sda2 8:2 0 19G 0 part 
 ├─rhel-root 253:0 0 17G 0 lvm /
 └─rhel-swap 253:1 0 2G 0 lvm [SWAP]
sdb 8:16 0 10G 0 disk 
sr0 11:0 1 3.8G 0 rom /run/media/root/RHEL-7.4 Server.x86_64 --- This is the image of the attached store CD


3、 Create a mount point and write to the configuration file

Mount point

[[email protected] ~]# mkdir /media/cdrom


Write profile

[[email protected] ~]# vim /etc/fstab 
/dev/cdrom /media/cdrom iso9660 defaults 0 0 --- Add this line


mount

[[email protected] ~]# mount -a
mount: /dev/sr0 is write-protected, mounting read-only


4、 Write yum Configuration file of warehouse

Go to configuration directory

[[email protected] ~]# cd /etc/yum.repos.d/


Write profile

Be careful ： The name of the document is optional , But the suffix must be .repo, Write the following configuration parameters one by one and exit （ Don't write the following Chinese Notes ）

[[email protected] yum.repos.d]# vim rhel7.repo 
[rhel] ---Yum Software warehouse unique identifier , Avoid conflicts with other warehouses
name=rhel ---Yum Description of the name of the software warehouse
baseurl=file:///media/cdrom --- The ways provided include FTP（ftp://..）、HTTP（http://..）、 Local （file:///..）
enable=1 --- Set whether this source is available ;1 Available for use ,0 To disable .
gpgcheck=0 --- Set whether this source verifies files ;1 For verification ,0 For not checking


Save and exit

5、 eliminate yum Warehouse cache

[[email protected] yum.repos.d]# yum clean all
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
 : manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
Cleaning repos: rhel
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos


6、 Generate cache

[[email protected] yum.repos.d]# yum makecache 
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
 : manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
rhel | 4.1 kB 00:00 
(1/5): rhel/group_gz | 137 kB 00:00 
(2/5): rhel/filelists_db | 3.4 MB 00:00 
(3/5): rhel/primary_db | 4.0 MB 00:00 
(4/5): rhel/other_db | 1.5 MB 00:00 
(5/5): rhel/productid | 1.6 kB 00:00 
Metadata Cache Created


7、 Test whether the installation is successful

Install any software

I choose to install  tree

[[email protected] ~]# yum install tree -y
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
 : manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
