Como atualizar o Oracle Linux 8 para Oracle Linux 9

Hoje realizaremos o processo de atualização do Oracle Linux 8 para o Oracle Linux 9 usando o utilitário Leapp. Lembre-se sempre de testar todos os serviços, pacotes e aplicações antes de migrar seus servidores para produção.

O utilitário Leapp é um utilitário para atualizar sistemas operacionais e aplicativos.
As operações da Leapp consistem em duas fases: uma fase de pré-atualização que executa verificações do sistema para determinar se o software pode ser atualizado. A segunda fase é a atualização propriamente dita, cujo processo é baseado em arquivos de configuração que mapeiam os pacotes entre as versões anteriores e atuais do software.

1 – Confirmando que nossa versão do Oracle Linux é 8.

[root@srvol8 ~]# cat /etc/*-release | grep PRETTY
PRETTY_NAME="Oracle Linux Server 8.6"
[root@srvol8 ~]#
ShellScript

2 – Verificar todos os serviços ou aplicativos atualmente utilizados no ambiente.

3 – Interrompa toda a carga de trabalho existente, como banco de dados ou servidores da web.

[root@srvol8 ~]# systemctl stop mysql
[root@srvol8 ~]# systemctl status mysql
[root@srvol8 ~]# systemctl stop zabbix-server
[root@srvol8 ~]# systemctl status zabbix-server
ShellScript

4 – Desabilite o Secure Boot se estiver rodando.

root@srvol8 ~]# sudo bootctl status

          ESP: /boot/efi (/dev/disk/by-partuuid/e9538cc4-b078-43d9-aca8-cdf8e635edae)
systemd-boot not installed in ESP.
         File: └─/EFI/BOOT/BOOTX64.EFI
Boot Loader Entries in EFI Variables:

LANG=en_US.UTF-8
# If necessary, edit the file to set the locale accordingly.
sudo localectl set-locale LANG=en_US.UTF-8
ShellScript

6 – Se o seu SO possuir nfs montados em rede, desmonte-os e comente as entradas relacionadas no arquivo /etc/fstab.

	
[root@srvol8 ~]# umount /BACKUP
ShellScript

7 – Se você instalou o pacote yum-plugin-versionlock, limpe todos os pacotes com versões bloqueadas.

[root@srvol8 ~]# dnf versionlock list
No such command: versionlock. Please use /bin/dnf --help
It could be a DNF plugin command, try: "dnf install 'dnf-command(versionlock)'"
[root@srvol8 ~]#
[root@srvol8 ~]# dnf versionlock clear
No such command: versionlock. Please use /bin/dnf --help
It could be a DNF plugin command, try: "dnf install 'dnf-command(versionlock)'"
ShellScript

8 – Se necessário configure o proxy Yum para poder atualizar o Oracle Linux.

[root@srvol8 ~]# cat /etc/yum.conf
proxy=<proxy-url>:<port>
ShellScript

9 – Atualizar pacotes com o DNF:

[root@srvol8 ~]# dnf update -y

Title: The OS Management Service (OSMS) agent is running on this instance.
Summary: The OSMS service is active on this instance.
 
The OS Management Service does not currently support Oracle Linux 9 AppStreams, also known as modules or module streams.
Upgrade cannot proceed with the OSMS agent active. Please refer to https://docs.oracle.com/en-us/iaas/os-management/osms/osms-getstarted.htm for more information about OSMS and Oracle Linux 8.
Remediation: [hint] The OSMS agent is included in OCI Oracle Linux platform images and installed by default. If the instance is not actively managed by OSMS, the OSMS agent can be disabled from the OCI console and the upgrade can proceed. Please refer to https://docs.oracle.com/en/operating-systems/oracle-linux/9/leapp/ for information about disabling the OSMS agent.
