国产化替代必看：银河麒麟服务器系统版本升级指南

在信息技术应用创新加速推进的今天，银河麒麟作为国产服务器操作系统的中坚力量，承载着越来越多的关键业务。本文将带您深入银河麒麟服务器升级的完整流程与实战要点。

1.当前系统版本

[root@localhost ~]# nkvers
############## Kylin Linux Version #################

2.在线升级

2.1备份yum源

[root@localhost ~]# mv /etc/yum.repos.d/kylin_x86_64.repo /etc/yum.repos.d/kylin_x86_64.repo.bak

2.2修改yum源

修改需要升级的版本yum源

[root@localhost ~]# vim /etc/yum.repos.d/kylin_x86_64.repo
###Kylin Linux Advanced Server 10 – os repo###

[ks10-adv-os]
name = Kylin Linux Advanced Server 10 – Os
baseurl = https://update.cs2c.com.cn/NS/V10/V10SP3-2403/os/adv/lic/base/$basearch/
gpgcheck = 1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-kylin
enabled = 1

[ks10-adv-updates]
name = Kylin Linux Advanced Server 10 – Updates
baseurl = https://update.cs2c.com.cn/NS/V10/V10SP3-2403/os/adv/lic/updates/$basearch/
gpgcheck = 1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-kylin
enabled = 1

[ks10-adv-addons]
name = Kylin Linux Advanced Server 10 – Addons
baseurl = https://update.cs2c.com.cn/NS/V10/V10SP3-2403/os/adv/lic/addons/$basearch/
gpgcheck = 1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-kylin
enabled = 0

2.3使用yum update 升级

[root@localhost ~]# yum update

2.4重启系统查看版本

[root@localhost ~]# reboot

注意：升级后授权文件(/etc/.kyinfo)不变

[root@localhost ~]# nkvers

需要升级为什么版本就挂载对应的镜像源

[root@localhost ~]# mkdir /kylinImage
[root@localhost ~]# mount /dev/cdrom /kylinImage

3.2.备份原yum源并新建本地yum源文件

[root@localhost ~]# mv /etc/yum.repos.d/kylin_x86_64.repo /etc/yum.repos.d/kylin_x86_64.repo.bak
[root@localhost ~]# vim /etc/yum.repos.d/kylin_local.repo
[local]
name = local repo
baseurl = file:///kylinImage
gpgcheck = 0
enabled = 1
