CentOS 8 The end of life Make in the enterprise Linux There is a serious gap left in the market , This shifts the focus to other enterprise levels Linux On the distribution ( bye CentOS 8/6！ Try these best alternatives ).

stay Ubuntu、Red Hat Enterprise Linux (RHEL)、AlmaLinux and SUSE And other respected enterprises Linux Distribution in , As feasible CentOS 8 The distribution where alternatives stand out is Oracle Linux, This is a kind of from and RHEL Operating system compiled from the same open source code .

Oracle provides a secure open source platform for enterprises , Ideal for database environments .LinuxSecurity Researchers and Oracle Linux And the virtualization product management team Honglin Su as well as Kernel The development team answered our questions about why Oracle Linux It is an excellent operating system for security conscious enterprises 、 What makes this distribution a logical enterprise class CentOS A substitute for the problem ,Oracle Linux The future of , Other questions ！

Oracle Linux： A comprehensive open source operating system that emphasizes security

since 2006 year Oracle Linux Since the launch ,Oracle Linux Always completely free to download and use , No license fee is required .Oracle Support for a complete operating environment , This environment provides integrated virtualization 、 Management and cloud native computing tool suite , as well as Linx operating system .Oracle Linux For all Oracle Software workloads are optimized out of the box , Enable the enterprise to run on the same operating system that developed it Oracle database .

As security vulnerabilities increase , Fast 、 The ability to seamlessly apply security fixes is becoming increasingly important —— Especially as more and more enterprises adopt container technology to build cloud based applications .Oracle Linux Through the... Without restart Ksplice Automatic patching to reduce the risk of attacks that exploit unpatched vulnerabilities , Make it unique for the kernel 、 Hypervisors and key user space libraries provide zero downtime for automatic patching Linux Distribution version .

What makes Oracle Linux More secure and optimized ？

Oracle Linux With security defaults , And bring first-class security functions to the enterprise , For example, through Ksplice For the kernel 、 Zero downtime patch update for hypervisor and user space 、 Known vulnerability detection and modern Linux kernel .

what's more , Oracle is already in Oracle Linux On “ Bets ” 了 . As a leading database provider and first-class cloud provider ,Oracle Everything is done in Oracle Linux Built and run on .

Oracle It's the industry Linux Members of the security response team , Work with others to solve industry wide safety problems , Enable secure hardware technology , Proactively solve and eliminate safety problems , Provide innovative open source technologies , for example SELinux、Kata Containers 、 Multi process QEMU etc. FIPS Verification and Common Criteria (CC) The certification proves Oracle Commitment to safety .

Besides , Oracle performs routine audits , And have an internal “ Ethical hacker team ”. They use fuzzy testing tools in their internal development workflow , And run multiple static analysis tools as a normal part of the build process .

many Linux Distribution version , Especially in the enterprise field , Tend to use the same kernel 5 To 10 year , And provide repair and function reverse porting for the kernel .Oracle Linux There are two cores to choose from , That is, installed and enabled by default Unbreakable Enterprise Kernel (UEK) and Red Hat Compatible Kernel.UEK for Oracle Linux Allow customers to leverage upstream Linux The latest development of .

UEK Pay close attention Linux Long term stability of the kernel (LTS) edition , Publish monthly updates , Here are these updated KABI Stable version . kernel LTS Maintainer Greg Kroah-Hartman The observed , Of all security vulnerabilities reported against the kernel , Nearly half of them are “ Traceable ”, That is, they are for those already included in the upstream Linux Patch submission in , And it is usually included in the long-term stable version .

Oracle Track modern Linux The strategy of the kernel means , Even in the future CVE Identifiers are assigned to these patches before , Customers can also use the latest security fixes to run . If not , That's it Oracle Ksplice Use UEK Of Oracle Linux Has been fully tested , Can be used to run Oracle The integrated system （Exadata、 Private cloud devices, etc ）、Oracle Cloud infrastructure and for Oracle Customer's large enterprise deployment .

for example , Based on mainline Linux kernel 5.4.17 Of UEK Release 6 Can be used for Oracle Linux 7 and 8, And support Intel/AMD (x86-64) as well as Arm (aarch64) platform . It provides the latest open source innovations for cloud and local workloads 、 Critical optimization and security . Customers can cross major Linux Version runs the same modern Linux kernel . And the corresponding RHEL 7 and 8 The kernel is still based on the mainline kernel 3.10 and 4.18.

function Oracle Linux You can also use the Oracle Real Application Clusters (RAC) The implementation of Oracle Linux KVM To enhance the security and performance of critical applications , This helps create a virtualized data center for high availability applications .DTrace Features provide comprehensive kernel and application tracing , Enable administrators and developers to be efficient 、 Answer questions about the operating system and the behavior of user programs in real time .

Oracle Linux Support to provide the latest cloud native tools based on open standards for free , as well as KVM Server virtualization and based on oVirt Virtualization manager for .Oracle The cloud native environment is based on the open container initiative (OCI) And the cloud native Computing Foundation (CNCF) standard , Installation of key open source technologies for choreographing microservices 、 to update 、 Upgrades and configurations provide a simplified framework . Use a select set of tested and supported open source components , for example Kubernetes and Kata Containers – with Oracle Linux Of Oracle Cloud native environments are ideal for hybrid clouds .

Need a stable 、 compatible RHEL Of CentOS succedaneum ？Oracle Linux At your service .

Red Hat stop it CentOS 8 's decision has many users scrambling to find cost-effective 、 Safe and compatible RHEL An alternative to . If you are currently facing this important decision and are studying possible CentOS succedaneum , Please don't neglect Oracle Linux.

Oracle Linux May be CentOS A better alternative to . The operating system is reliable 、 The price is reasonable and 100% compatible RHEL. But there are more benefits , This distribution gives you access to Linux Some of the most cutting-edge innovations in , for example Ksplice and DTrace. Besides ,Oracle Linux The version is always the same as Red Hat Enterprise Linux bring into correspondence with , Errata are usually in 24 Within hours , An updated version is usually available within five working days , The major version will be released within three months , Make sure you switch to Oracle Linux Will not meet again CentOS The risk of delay ！

Now you may ask yourself questions ：“ But it's like CentOS Is it free ？” The answer is “ Yes , Provide optional support services ”. You can decide which... Should be supported Oracle Linux System . however , Non paying customers can get the same kernel version and rock solid code quality as paying customers .

from CentOS Switch to Oracle Linux Is seamless and easy ！

Oracle Linux The team created a simple script , Can be used for CentOS 8、7 and 6 The system switches to Oracle Linux Explanation .

The script has two main functions ： Put your yum Configuration switch to use Oracle Linux, yum The server updates some core packages , And install the latest Oracle Linux Abreast of the times Unbreakable Enterprise Kernel. There is no need to restart after switching , But we recommend that you do so to take advantage of UEK. Yes , It's really that simple ！
