How to create and add a Local YUM Repository on RHEL or CentOS 7

How to setup local yum repository on RHEL or CentOS 7? 



This tutorial describes how to setup a local Yum repository on CentOS or RHEL 7 system. Later i will show you how you can use this repository to fetch software, security updates and fixes. Local repository is an efficient way to deploy new software's or patches as it will be over LAN where deployment will be fast, saving your internet bill.

I have two CentOS 7 systems here one is YUM repository server and another will be Client which will fetch the updates from repository server over FTP protocol.


Setting up YUM repo server with FTP:

Step 1. Mount CentOS 7 ISO and copy all the RPM packages to a FTP directory:

[root@localhost ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 is write-protected, mounting read-only

[root@localhost ~]# mkdir /var/ftp/pub/localrepo

[root@localhost ~]# cp -ar /mnt/Packages/* /var/ftp/pub/localrepo/


Step 2. Install vsftpd package and start it's service:

[root@localhost ~]# cd /mnt/Packages/

[root@localhost ~]# rpm -ivh vsftpd-3.0.2-25.el7.x86_64.rpm

[root@localhost ~]# systemctl enable vsftpd

[root@localhost ~]# systemctl start vsftpd


Step 3. Install "createrepo" package and it's dependencies:

[root@localhost ~]# rpm -ivh libxml2-python-2.9.1-6.el7_2.3.x86_64.rpm

[root@localhost ~]# rpm -ivh deltarpm-3.6-3.el7.x86_64.rpm

[root@localhost ~]# rpm -ivh python-deltarpm-3.6-3.el7.x86_64.rpm

[root@localhost ~]# rpm -ivh createrepo-0.9.9-28.el7.noarch.rpm


Step 4. Create repository

[root@localhost ~]# createrepo -v /var/ftp/pub/localrepo/


Step 5. If this repository is going to be on your LAN then disable firewall and SELinux:

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# systemctl disable firewalld

To disable SELinux, edit file /etc/sysconfig/selinux,

SELINUX=disabled

Save, exit and reboot host.


Step 6. [OPTIONAL] Test if repository is working fine on YUM server:

[root@localhost ~]# vi /etc/yum.repos.d/localrepo.repo

[localrepo]
name=Local Repository
baseurl=file:///var/ftp/pub/localrepo
gpgcheck=0
enabled=1

Save and Exit.

Setting up Client to get YUM repo on FTP :


[root@localhost ~]# vi /etc/yum.repos.d/localrepo.repo

[localrepo]
name=Local Repository
baseurl=ftp://192.168.189.1/pub/localrepo
gpgcheck=0
enabled=1


Save and Exit.

Clean the Yum cache and update the repository lists:

[root@localhost ~]# yum clean all
[root@localhost ~]# yum update

Try to install any package:

[root@localhost ~]# yum install ethtool

Recover or restore initramfs file in RHEL or CentOS 7

Image
What if "initramfs" file is deleted or corrupted on your RHEL or CentOS 7 ? Lets know what is initramfs image ? The INITial RAM Disk (initrd) is an initial root file system that usually get mounted prior to when the real root file system gets available. The "initrd" image is also known as "initramfs (Initial RAM FileSystem)" from RHEL 6.x onwards. The initrd/initramfs gets bound to the kernel and loaded as part of the kernel boot procedure. The kernel then mounts this initrd/initramfs as part of the two-stage boot process to load the modules to make the real file systems available and mount's the real root file system. Initrd/Initramfs image provides the capability to load a RAM disk by the boot loader. This RAM disk can then be mounted as the root filesystem and programs can be run from it. Afterwards, a new root file system can be mounted from a different device. The previous root filesystem which was mounted from initrd/initramfs is then

Space reclamation / UNMAP on RHEL or CentOS 7

What is Space Reclamation? This feature supports Thin Provisioned environment, and it is the process of freeing space from the storage system that has already been freed from the host file system. A host file system contains metadata to keep track to know which blocks are available to store new data and which blocks contain actual data and must not be overwritten. This metadata is stored within the LUN. When a file is deleted in the host file system, the file system metadata is updated to mark that file's blocks as free space. Total file system free space is then recalculated to include the newly-freed blocks. To the storage system, these metadata updates appear no different than any other writes being performed by the host. Therefore, the storage system is unaware that any deletions have occurred. What is Unmapping? Unmapping is a process which de-allocates relationship between LBA and a physical block in a logical unit. Reclamation within RHEL and CentOS: RHEL / Ce

How to recover /boot partition on RHEL or CentOS 7?

What if mistakenly you delete all the files from /boot partition or files got corrupted due to some reason ! You will see below error on the screen at the time of system boot. But there is a way to recover /boot partition files :) Follow these steps to recover /boot partition : Step 1 :  Mount RHEL or CentOS 7 ISO image on your physical server and boot from it. In case you are using HPE Prolient server you can mount this ISO image on iLO, if this is virtual environment then mount it accordingly and reboot server or VM from ISO. Once rebooted you will see below options: Step 2 :  Scroll down and select "Troubleshooting" option from menu and PRESS "Enter" Step 3 :  Select "Rescue a CentOS system" and press ENTER: Step 4 :  Press ENTER key again to continue: Step 5 :  To continue, Type "1" and press ENTER, this will bring you to rescue mode, chroot sysimage filesystem using below command:
