[步骤] 系统升级 （从 openSUSE Leap 15.4 升级到 openSUSE Leap 15.5）

步骤一：显示现在的系统版本

# cat /etc/*release*
NAME="openSUSE Leap"
VERSION="15.4"
ID="opensuse-leap"
ID_LIKE="suse opensuse"
VERSION_ID="15.4"
PRETTY_NAME="openSUSE Leap 15.4"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:leap:15.4"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/"

（注意：确保显示的系统版本是 openSUSE Leap 15.4）

步骤二：准备升级

2.1 确认已使用的软件库

# zypper ls -d
#  | Alias                     | Name                               | Enabled | GPG Check | Refresh | Priority | Type   | URI
---+---------------------------+------------------------------------+---------+-----------+---------+----------+--------+---------------------------------------------------------------------------------------------
1  | repo-non-oss              | Non-OSS Repository                                           | Yes     | (r ) Yes  | Yes     |   99     | rpm-md | http://download.opensuse.org/distribution/leap/15.4/repo/non-oss/
2  | repo-oss                  | Main Repository                                              | Yes     | (r ) Yes  | Yes     |   99     | rpm-md | http://download.opensuse.org/distribution/leap/15.4/repo/oss/
3  | repo-update               | Main Update Repository                                       | Yes     | (r ) Yes  | Yes     |   99     | rpm-md | http://download.opensuse.org/update/leap/15.4/oss/
4  | repo-update-non-oss       | Update Repository (Non-Oss)                                  | Yes     | (r ) Yes  | Yes     |   99     | rpm-md | http://download.opensuse.org/update/leap/15.4/non-oss/
5  | repo-backports-update     | Update repository of openSUSE Backports                      | Yes     | (r ) Yes  | Yes     |   99     | rpm-md | http://download.opensuse.org/update/leap/15.4/backports/
6  | repo-sle-update           | Update repository with updates from SUSE Linux Enterprise 15 | Yes     | (r ) Yes  | Yes     |   99     | rpm-md | http://download.opensuse.org/update/leap/15.4/sle/

（
补充：
1) 确保以上软件库已处于 Enabled 状态
2) 手动启动这些软件库的命令如下

# zypper ar -fcg http://download.opensuse.org/distribution/leap/${releasever}/repo/non-oss/ Non-OSS Repository
# zypper ar -fcg http://download.opensuse.org/distribution/leap/${releasever}/repo/oss/ Main Repository
# zypper ar -fcg http://download.opensuse.org/update/leap/${releasever}/oss/ Main Update Repository
# zypper ar -fcg http://download.opensuse.org/update/leap/${releasever}/non-oss/ Update Repository (Non-Oss)
# zypper ar -fcg http://download.opensuse.org/update/leap/${releasever}/backports/ Update repository of openSUSE Backports
# zypper ar -fcg http://download.opensuse.org/update/leap/${releasever}/sle/ Update repository with updates from SUSE Linux Enterprise 15

3) 其中，Main Repository、Main Update Repository、Update repository of openSUSE Backports 和 Update repository with updates from SUSE Linux Enterprise 15 软件库是必须要有的，其他的软件库可以去掉

）

2.2 刷新已使用的软件库

# zypper ref

（注意：确保刷新成功，否则请检查网络）

2.3 将所有 openSUSE Leap 15.4 软件包更新到最新版本

# zypper -n update

2.4 用 releasever 变量替换所有版本号

# sed -i 's/15.4/${releasever}/g' /etc/zypp/repos.d/*.repo

步骤三：升级系统

3.1 将版本号设置为 15.5 并刷新

# zypper --releasever=15.5 refresh

3.2 提前下载并安装 openSUSE Leap 15.5 所需的软件包

# zypper --releasever=15.5 dup --download-in-advance

3.3 升级系统

# zypper --releasever=15.5 dup

3.4 重启系统

# reboot

步骤四：后续检查

[排错] RHEL 解决使用 yum 命令时卡住

报错代码

# yum update 
Updating Subscription Management repositories.
Unable to read consumer identity

可尝试的解决方法一：修改 /etc/yum/pluginconf.d/subscription-manager.conf 文件

# vim /etc/yum/pluginconf.d/subscription-manager.conf

将以下内容：

......
[main] 
enabled=1
......

修改为：

......
[main] 
enabled=0
......

可尝试的解决方法二：安装对应的 katello-ca-consumer-latest.noarch.rpm 软件包

（步骤略）

（补充：katello-ca-consumer-latest.noarch.rpm 软件包下载自对应的 Red Hat Satellite 服务器，补充链接：Red Hat Satellite client register）

[步骤] RHEL 系统的注册 （注册到 Red Hat 官网）

正文：

步骤一：清除旧有的注册信息

1.1 清除所有的旧有注册信息

# subscription-manager remove --all

1.2 取消注册

# subscription-manager unregister

1.3 清楚所有的就有数据

# subscription-manager clean

确保部分内容如下：

......
hostname = subscription.rhsm.redhat.com
......
baseurl = https://cdn.redhat.com
......

步骤三：注册 RHEL 系统到 Red Hat 官网

3.1 非交互式

# subscription-manager register --username <username> --password <password> --auto-attach

（注意：如果完成了本文的 2.1 就不用再执行 本文的 2.2 了）

3.2 交互式注册 RHEL 系统到 Red Hat 官网

3.2.1 交互式注册 RHEL 系统到 Red Hat 官网
# subscription-manager register
3.2.2 在 Red Hat 官网上将相关订阅 （license） 分配给系统

登录 Red Hat 官网 –> Red Hat Customer Portal –> subscriptions –> systems –> <system name> –> 添加订阅
