Centos 7 Dvd Iso

  

In order to conserve the limited bandwidth available, ISO images are not downloadable from mirror.centos.org The following mirrors in your region should have the ISO images available. Copy the full CentOS 7.6.1810 binary DVD ISO image to a suitable directory on the NFS server. For example, you can create directory /CentOS-install/ for this purpose and save the ISO image here. Open the /etc/exports file using a text editor and add a line with the following syntax. 199 rows  Name Last modified Size Description; Parent Directory - CentOS-7-x8664-DVD-1505-01.iso. For the snippets and examples used of this article I will be using Red Hat 7.3 vanilla DVD content but the same steps can be used to create a customized CentOS DVD. NOTE: With RHEL 8 now you have cockpit image builder using which you can create images in various formats including ISO, QCOW2 etc.

After three weeks of continuous testing, CentOS project team finally on Mon July 7the 2014 released CentOS Linux 7 for 64 bit x86 compatible systems. This is the first major release for CentOS 7 and actual version is 7.0-1406.

This newly released CentOS 7.0 is an Enterprise-class Linux Distribution built from sources and freely maintained to the public by Red Hat. This release is based on the upstream release of EL7 (Enterprise Linux 7) and most of the packages have been built from source and updated to more recent versions.

There are countless fundamental changes in this major release, compared to earlier versions of CentOS. Notably the involvement of Gnome3, Systemd, and a default XFS filesystem.

CentOS 7 Major Changes

Following are the more notable changes are included in this release are:

  1. Updated Kernel to 3.10.0
  2. Added support for Linux Containers
  3. Open VMware Tools & 3D graphics drivers out of the box
  4. OpenJDK-7 as default JDK
  5. Upgrade from 6.5 to 7.0 using preupg command
  6. LVM-snapshots with ext4 and XFS
  7. Switch to grub2, systemd and firewalld

  10. Support for PTPv2
  11. Support for 40G Ethernet Cards
  12. Supports installations in UEFI (Unified Extensible Firmware Interface) Secure Boot form on compatible hardware

Before you go for CentOS 7.0 after CentOS 6.x, I suggest you to consider following things, because many of things have been changed in this release.

Centos
  1. grub is now replaced with grub2
  2. init is now replaced with systemd
  3. Difficultly in understanding and editing grub.conf (grub2)
  4. Difficultly in understanding /etc/init.d
  5. No more text log files for system log (journalctl instead)
  6. No more ext4 filesystem, added XFS as default filesystem
  7. CentOS 6.x will be supported until 2020

2. Introduction

Hello and welcome to the eighth CentOS-7 release. The CentOS Linux distribution is a stable, predictable, manageable and reproducible platform derived from the sources of Red Hat Enterprise Linux (RHEL)1. You can read our official product announcement for this release here.

CentOS conforms fully with Red Hat's redistribution policy and aims to have full functional compatibility with the upstream product. CentOS mainly changes packages to remove Red Hat's branding and artwork.

We have decided not to follow Red Hat's usage of Installation Roles. In CentOS Linux all content from every distribution 'channel' is made available to the user at time of installation.

The CentOS Project does not provide any verification, certification, or software assurance with respect to security for CentOS Linux. The Security Profiles provided in the CentOS Linux installers are a conversion of the ones included in RHEL Source Code. If certified / verified software that has guaranteed assurance is what you are looking for, then you likely do not want to use CentOS Linux. See this link if you plan to use Security Profiles.

3. Install Media

Various installation images are available for installing CentOS. Which image you need to download depends on your installation environment. All of these images can either be burned on a DVD or dd’ed to an USB memory stick.

If you are unsure which image to use, pick the DVD image. It allows selecting which components you want to install and contains all packages that can be selected from the GUI installer. The 'Everything' image is more than twice the size of the ordinary DVD and is not required for most common installs - it is intended for use by sysadmins who want to run their own local mirror. Using the Everything image does not give you more options for package selection within the installer.

Live media images are also available, both for Gnome and KDE desktop environments. These allow you to test out CentOS by booting from the DVD or USB stick. You can also install CentOS to your hard disk from the live media images, but please note that what gets installed on your hard disk is exactly the same as you see when using the live media. For more flexibility in selecting which packages you want to have installed, please use the DVD image.

The netinstall image can be used for doing installs over network. After booting the computer with the netinstall image, the installer will ask from where it should fetch the packages to be installed.

The everything image contains all the packages that are available for CentOS-7, including those that are not directly installable from the installer. If you want to install those other packages, you must mount the install media on your installed system after the installation, and copy or install the packages from there. For most users installing from the DVD image and then installing the other packages with ”yum install <packagename>” instead is probably easier.

Attention
At least 1280 MB RAM is required to install and use CentOS-7 (1810). When using the Live ISOs for install, 1280 MB RAM produces very slow results and even some install failures. At least 1536 MB RAM is recommended for LiveGNOME or LiveKDE installs.

4. Verifying Downloaded Installation Images

Before copying the image to your preferred installation media you should check the sha256sum of the downloaded installation images.

5. Major Changes

  • Python 3 is now available. Installing the python3 package gives you the Python 3.6 interpreter.

  • bind has been rebased to version 9.11
  • chrony has been rebased to 3.4

  • Since release 1503 (abrt>= 2.1.11-19.el7.centos.0.1) CentOS-7 can report bugs directly to bugs.centos.org. You can find information about that feature at this page.

  • If you plan to use Security Profiles in Anaconda, please see this link.

  • Many packages have received important updates. Please see the upstream document for details.

6. Deprecated Features

Please see the list of deprecated functionality to help you plan forward with future deployments.

7. Known Issues

A list of known upstream issues can be found here. Given that we build from the same sources, many if not all of those issues will likely also apply to CentOS Linux.

Some security profiles enable a global repo_gpgcheck option in /etc/yum.conf to cryptographically verify the repository metadata. While this works for CentOS repositories, some third party repositories (such as EPEL) do not support GPG signed metadata. If repo_gpgcheck is enabled yum will try to download the signed metadata file repomd.xml.asc. If the file does not exist, yum will output an error message and exit. You may need to either remove repo_gpgcheck from /etc/yum.conf or set repo_gpgcheck=0 for each individual repository that does not support GPG signed metadata.

Red Hat have updated the freerdp packages to the 2.x branch and many things in third party yum repos that build against freerdp will need to be rebuilt to cater for this. Known packages affected by this change are: vlc and remmina (both from nux-dextop). You will need to wait for the nux-dextop repo to update vlc before you can update. The good news is that there is a much newer version of Remmina in (currently) epel-testing that installs on 7.7. You can also find a newer, up to date, vlc in flatpak.

If you use KDE and your default shell is csh or tcsh, you will see the error 'if: Expression Syntax'. This is a known bug. See RHBZ #1738491 for details and a fix.

Installing the VirtualBox Addons will produce an error if your version is 6.0.12/5.2.32 or lower.

In certain configurations selecting the 'Install CentOS 7 in basic graphics mode' option may use text mode instead of basic graphics mode.

The samba 4.9 upgrade has been reported to cause the service to fail to start with an error about a missing BUILTINGuests group or 'create_local_token failed: NT_STATUS_ACCESS_DENIED'. The fix for this is to run net -s /dev/null groupmap add sid=S-1-5-32-546 unixgroup=nobody type=builtin as per this Fedora Bugzilla entry https://bugzilla.redhat.com/show_bug.cgi?id=1648399 which is worth a read for some other config changes too.

The iptables upgrade (iptables-1.4.21-33.el7.x86_64) has been reported to cause iptables-restore failure when a '-' and a 't' are used in the comment field. This is a known bug. See https://bugzilla.redhat.com/show_bug.cgi?id=1749700 for details.

11. How to help and get help

As a CentOS user there are various ways you can help out with the CentOS community. Take a look at our Contribute page for further information on how to get involved.

11.1. Special Interest Groups

CentOS consists of different Special Interest Groups (SIGs) that bring together people with similar interests. The following SIGs already exist (among others):

  • Artwork - create and improve artwork for CentOS releases and promotion

  • Promotion - help promoting CentOS online or at events

  • Virtualization - unite people around virtualization in CentOS

And we encourage people to join any of these SIGs or start up a new SIG, e.g.

  • ARM, PPC and i386 port - help with porting CentOS to other architectures
  • Hardware compatibility - provide feedback about specific hardware
  • RPM Packaging - contribute new useful RPM packages
  • Translation - help translating the documentation, website and Wiki content

11.2. Mailing Lists and Forums

Another way you can help others in the community is by actively helping and resolving problems that users come up against in the mailing lists and the forums.

11.3. Wiki and Website

Even as an inexperienced CentOS user we can use your help. Because we like to know what problems you encountered, if you had problems finding specific information, how you would improve documentation so it becomes more accessible. This kind of feedback is as valuable to others as it would have been to you so your involvement is required to make CentOS better.

So if you want to help out and improve our documentation and Wiki, register on the Wiki or subscribe to the centos-docs mailing list.

11.4. IRC Presence

The CentOS project maintains a presence on the freenode IRC network as an additional venue for community support and interaction. Please see our IRC wiki article for more information.
