Redhat7.0 Installation

Redhat7.0 After the release, has not time to see, recently intended to install a test feel. 650) this.width=650; "src=" Http://img.baidu.com/hi/jx2/j_0027.gif "alt=" J_0027.gif "/>

The Redhat7.0 version is still in beta, and as opposed to the previous version, the change is very big, first of all the interface is a bit of fedora flavor, and secondly redhat7.0 adds a lot of new features.
Docker

The new feature of the most bright eye in RHEL 7 belongs to Docker. The current explosion of pop-up Docker container functionality was in fact early in Rhel 6.5. This week Docker has just launched version 1.0, and RHEL 7 is now the perfect fit.

Docker is based on the current popular Application virtualization technology. Applications are packaged in Docker and completely isolated from the system and other applications, so they can be migrated between systems and run properly. RHEL 7 leverages Docker technology fully and efficiently, so there is no contention for resources between applications.

Docker is also one of the hottest topics this week. From Rhel support for Docker long-term planning, it is likely that the operating system will later be split into a series of Docker containers, with minimal operating systems to complete as many deployments as possible, thus minimizing overhead. Red Hat and Docker created project Atomic to push Docker containers to their customers, and to ensure that Red Hat Enterprise Linux works regardless of where Docker is running.

Systemd

On systems and services, RHEL 7.0 replaced SysV with SYSTEMD. The SYSTEMD Process Manager raises the debate between the system administrator and the Linux expert. The purpose of the SYSTEMD is to replace the INIT system that has been in use since the Unix era and to boot the load service more efficiently during the process startup process.

Since the release of Fedora 15 in 2010, Red Hat has systemd as the default feature, thereby better experiencing SYSTEMD's performance in the real world. Red Hat does not casually add systemd to Rhel 7, but is part of its great operating system plan. Red Hat wants to enhance the way Rhel 7 supports Docker through SYSTEMD.

Xfs

RHEL 7 The third major change is the use of XFS instead of EXT4 as the default file system. XFS supports up to 500TB of capacity, while EXT4 supports only 50TB. However, Rhel 7 still supports EXT4.

XFS was originally created by Silicon Graphics international and has been put into production in Linux systems. RHEL 6 uses EXT4 as the default file system, although it comes with XFS options. Red Hat's competitor, SUSE Linux, also supports XFS, but the default support is ext3.

Unfortunately, in addition to backup and recovery, there is currently no practical way to migrate other file systems such as EXT4 or Btrfs on Rhel to XFS.

Microsoft-compatible authentication Management

Even administrators who do not advocate Microsoft Windows have to agree with Microsoft's Active Directory. Rhel 7 adds two key new features that improve the way Rhel works with AD. A cross-domain trust (Cross-realm trusts) is now established between RHEL 7 and AD, so ad users can access resources without logging on to the Linux side. RHEL 7 adds two external ad-related features that are REALMD, enabling automated querying with DNS information to add AD (or other Red Hat authentication services).

Performance co-pilot

Performance tuning without dynamic statistics is like driving a car without a windshield. So Rhel 7 introduced a new performance monitoring system for PCP (performance co-pilot). The system was originally developed by Silicon Graphics international and is now part of the Rhel 7. In addition to monitoring and documenting system status, PCP also supports APIs and toolsets that provide data to other subsystems, such as SYSTEMD.

RHEL 7.0 supports architectures such as 64-bit amd/intel, IBM Power7/power8/system z, and can download evaluation versions from their official website:

Red Hat directly publishes RHEL7 's source code to the CentOS site, and CentOS 7 should be released soon, given that CentOS is in fact a community distribution supported by Red Hat.

Once you've set up the above, you can continue, check dependencies and install packages, and then prompt you to set the root password and create users.

This window of bash is different, the overall change is still very big, a bit of Fedora taste. Other features await further exploration.
