背景
?????? 2020年12月08日CentOS 官方宣布CentOS Linux项目将停止,并推出CentOS Stream项目,详见CentOS官网公告。CentOS未来将会从Red Hat Enterprise Linux(RHEL)复刻版本的CentOS Linux转向CentOS Stream。对于当前处于生命周期中的CentOS版本和后续的影响如下:1、CentOS Linux 7作为RHEL 7的复刻版本,将会延续当前的支持计划,于2020年第四季度停止更新,并于2024年6月30日停止维护(EOL,End Of Life);2、CentOS Linux 8作为RHEL 8的复刻版本,生命周期会缩短,将在2021年12月31日停止维护(EOL),截止目前未看到该日期有延期的可能。3、不会再提供CentOS Linux 9及后续版本,将会提供CentOS Stream版本。
Stream滚动版会替代CentOS稳定版有什么影响呢?
我们先看看这几个版本的关系!!!
?如果你的服务器上安装了CentOS系统,有啥影响?
- 不再有bug修复更新,不会修复导致主机不稳定的BUG,同一个问题会一直让你头疼(可能没有这样的问题)。
- 不再为你提供新版本的软件包更新,以后就靠自己动手了。
- 稳定性降低,Stream滚动版可以理解为RHEL上游开发分支版本,稳定性必然是不如RHEL。对于生产系统稳定性的重要性你可以自己衡量。
- 寻找新的稳定版操作系统版本,可能是未来的
Rocky Linux 、Ubuntu或者SUSE还是ColorOS之类的其他系统。
??? ? ? 如果你的服务器是不对接公网,而仅仅是内部系统,那么对你来说影响并不大,因为很多服务?? 软件都是你自己使用源代码编译生成的。继续使用CentOS 8 也是可以的。
??????? 如果你的服务器对接公网,这就有网络安全问题啦, 一旦操作系统存在安全类的BUG,可以被攻击,那就遭了,这时你使用CentOS 8 心里也是没底了,总觉着这是颗定时炸弹一样。换掉它早晚是你的选择。
?为什么Stream滚动版会替代CentOS呢?
看原文:
The future of the CentOS Project is CentOS Stream, and over the next year we’ll be shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream, which tracks just ahead of a current RHEL release. CentOS Linux 8, as a rebuild of RHEL 8, will end at the end of 2021. CentOS Stream continues after that date, serving as the upstream (development) branch of Red Hat Enterprise Linux.
Meanwhile, we understand many of you are deeply invested in CentOS Linux 7, and we’ll continue to produce that version through the remainder of the RHEL 7 life cycle.
CentOS Stream will also be the centerpiece of a major shift in collaboration among the CentOS Special Interest Groups (SIGs). This ensures SIGs are developing and testing against what becomes the next version of RHEL. This also provides SIGs a clear single goal, rather than having to build and test for two releases. It gives the CentOS contributor community a great deal of influence in the future of RHEL. And it removes confusion around what “CentOS” means in the Linux distribution ecosystem.
When CentOS Linux 8 (the rebuild of RHEL8) ends, your best option will be to migrate to CentOS Stream 8, which is a small delta from CentOS Linux 8, and has regular updates like traditional CentOS Linux releases. If you are using CentOS Linux 8 in a production environment, and are concerned that CentOS Stream will not meet your needs, we encourage you to contact Red Hat about options.
We have an FAQ to help with your information and planning needs, as you figure out how this shift of project focus might affect you.
[See also: Red Hat's perspective on this.]
????? 大概意思:2021年CentOS项目组重点关注CentOS Stream发行版,建议将CentOS8更新到CentOS Stream发行版,如果你不想将Stream版本应用到生产系统,可以联系RHEL(建议你使用商业版)。
附:CentOS Linux镜像支持计划
阿里云上CentOS Linux公共镜像来源CentOS官方,当CentOS Linux停止维护后,阿里云将会同时停止对该系统的支持,CentOS Linux的支持计划如下:
