Hence if someone want to update the CentOS version they cannot use the yum command to update his Server CentOS version from Internet.

Footstep 2: Bank check Your Current CentOS Version
In our setup we have CentOS 7.7.1908 installed equally can exist seen from /etc/redhat-release output which we will upgrade to latest CentOS 7.8.2003(at the time of writing this article) Release.
[root@localhost ~]# cat /etc/redhat-release CentOS Linux release seven.seven.1908 (Core)
Step 3: Mount CentOS 7.8.2003 ISO Image
Before mounting the ISO Image locally you demand to first setup the directory path where you lot want to mount the image. Here I am creating a iso directory under /mnt path using mkdir /mnt/iso control and so mounting the ISO Paradigm in read-but using mount -o loop CentOS-7-aarch64-Minimal-2003.iso /mnt/iso command equally shown below.
[root@localhost ~]# mkdir /mnt/iso [root@localhost ~]# mount -o loop CentOS-7-aarch64-Minimal-2003.iso /mnt/iso mount: /dev/loop0 is write-protected, mounting read-only
Stride 4: Create the Repo File
Now you demand to create a repo file where you need to specify the ISO Epitome mount point and other relevant details to download the packages from baseurl.
[root@localhost ~]# half-dozen /etc/yum.repos.d/centos.repo [CentOS7-Repo] name=CentOS7 Server baseurl=file:///mnt/iso gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-Key-CentOS-7 enabled=ane gpgcheck=ane
Step v: Cleanup and List All YUM Repository
After setting upward the YUM Repository you lot demand to first perform the clean up using yum clean all command as shown beneath. This command will remove Enshroud of all the enabled YUM repositories.
[root@localhost ~]# yum clean all Loaded plugins: fastestmirror Cleaning repos: base of operations centos7-Server extras updates Cleaning up list of fastest mirrors
And so yous can list the repo id of all the YUM Repository that tin be enabled or disabled using yum repolist enabled command every bit shown below.
[root@localhost ~]# yum repolist enabled Loaded plugins: fastestmirror Determining fastest mirrors * base: d36uatko69830t.cloudfront.net * extras: d36uatko69830t.cloudfront.net * updates: d36uatko69830t.cloudfront.net base | 3.half-dozen kB 00:00:00 centos7-Server | three.6 kB 00:00:00 extras | 2.ix kB 00:00:00 updates | ii.ix kB 00:00:00 (one/6): CentOS7-Repo/group_gz | 3.five kB 00:00:00 (2/half dozen): base/7/x86_64/group_gz | 153 kB 00:00:00 (3/vi): centos7-Server/primary_db | 724 kB 00:00:00 (four/6): extras/7/x86_64/primary_db | 205 kB 00:00:00 (five/6): updates/7/x86_64/primary_db | three.0 MB 00:00:00 (half dozen/6): base/vii/x86_64/primary_db | half-dozen.1 MB 00:00:00 repo id repo name status base/vii/x86_64 CentOS-7 - Base 10,070 centos7-Server CentOS7 Server 443 extras/seven/x86_64 CentOS-seven - Extras 412 updates/7/x86_64 repolist: eleven,825
Step six: Update Your Organisation Using Local YUM Repository
Once repository is enabled you can download the updates past using below yum command where we are disabling all the other Repos except the i we just configured to avoid whatever unnecessary checking. Below yum command volition check and download all the updates from CentOS7-Repo repository as shown below.
[root@localhost ~]# yum --disablerepo=* --enablerepo=CentOS7-Repo update Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Bundle elfutils-default-yama-scope.noarch 0:0.176-2.el7 will be updated ---> Packet elfutils-default-yama-scope.noarch 0:0.176-4.el7 volition exist an update ---> Package grub2-common.noarch 1:2.02-0.eighty.el7.centos will exist updated --> Processing Dependency: grub2-common = 1:ii.02-0.lxxx.el7.centos for bundle: 1:grub2-tools-minimal-2.02-0.80.el7.centos.x86_64 --> Processing Dependency: grub2-mutual = i:two.02-0.80.el7.centos for package: 1:grub2-pc-2.02-0.80.el7.centos.x86_64 --> Processing Dependency: grub2-common = 1:2.02-0.80.el7.centos for package: i:grub2-tools-2.02-0.80.el7.centos.x86_64 --> Processing Dependency: grub2-common = 1:2.02-0.80.el7.centos for package: 1:grub2-tools-extra-2.02-0.80.el7.centos.x86_64 ---> Parcel grub2-mutual.noarch 1:two.02-0.81.el7.centos volition be an update ---> Package grub2-pc-modules.noarch 1:two.02-0.eighty.el7.centos will exist updated --> Processing Dependency: grub2-pc-modules = 1:2.02-0.fourscore.el7.centos for package: one:grub2-pc-two.02-0.80.el7.centos.x86_64 ---> Package grub2-pc-modules.noarch 1:ii.02-0.81.el7.centos will be an update ---> Package iwl7260-firmware.noarch 0:25.30.thirteen.0-76.el7 volition be obsoleting ---> Package iwl7265-firmware.noarch 0:22.0.7.0-72.el7 volition be obsoleted ---> Packet python-urlgrabber.noarch 0:iii.10-ix.el7 volition be updated ---> Bundle python-urlgrabber.noarch 0:three.10-x.el7 will be an update ---> Package selinux-policy.noarch 0:three.13.1-252.el7_7.six will exist updated ---> Package selinux-policy.noarch 0:3.13.1-266.el7 will be an update ---> Package selinux-policy-targeted.noarch 0:three.13.1-252.el7_7.6 will be updated ---> Packet selinux-policy-targeted.noarch 0:3.xiii.i-266.el7 will exist an update ---> Package setup.noarch 0:2.eight.71-10.el7 volition be updated ---> Package setup.noarch 0:2.viii.71-11.el7 volition be an update ---> Packet tuned.noarch 0:2.eleven.0-v.el7_7.i will be updated ---> Package tuned.noarch 0:2.eleven.0-8.el7 will exist an update ---> Package yum.noarch 0:iii.4.3-163.el7.centos will exist updated ---> Bundle yum.noarch 0:3.four.three-167.el7.centos will be an update ---> Bundle yum-plugin-fastestmirror.noarch 0:i.1.31-52.el7 volition be updated ---> Package yum-plugin-fastestmirror.noarch 0:1.1.31-53.el7 will be an update
Step seven: Check the Updated CentOS Version
After successful update if you lot again bank check the CentOS version so you can see it is now updated to vii.8.2003 from previous 7.seven.1908 version as shown below.
[root@localhost ~]# cat /etc/redhat-release CentOS Linux release vii.viii.2003 (Core)
Footstep 8: Unmount the Paradigm and Remove the Repo file
Once update is complete you can unmount the ISO image from /mnt/iso path using umount /mnt/iso command and delete the created yum repository using rm -rf /etc/yum.repos.d/centos.repo command equally shown beneath.
[root@localhost ~]# umount /mnt/iso/ [root@localhost ~]# rm -rf /etc/yum.repos.d/centos.repo
