Instalação do Oracle VM Manager
By franky
Olá pessoal, aqui vamos demonstrar como instalar e configurar o Oracle VM Manager num servidor fora do Oracle VM Server que foi instalado no último post. O Oracle VM Manager é, como o próprio nome já diz, um gerenciador para toda a nossa infraestrutura virtualizada. A instalação é bastante simples, mas o ambiente parece ser um pouco complexo em sua composição:
- MySQL Database Server
- Java
- Oracle WebLogic Server
- Oracle ADF
- Oracle VM Manager application
- Oracle WebLogic Server domain
Configurações do servidor:
- Sistema Operacional: Oracle Linux Server 7.5 - Armazenamento: SSD 240GB - Memória Física: 16GB - Quantidade de Cores: 4 físicos (8 lógicos)
O primeiro passo é efetuar o download da mídia a partir do Patch 22902502 no MOS.
Feito isso vamos descompactar o arquivo p22902502_345_Linux-x86-64.zip no diretório desejado
[root@vision ~]# unzip /home/loredata/Downloads/VMManager/p22902502_345_Linux-x86-64.zip -d /home/loredata/Downloads/VMManager/ Archive: /home/loredata/Downloads/VMManager/p22902502_345_Linux-x86-64.zip inflating: /home/loredata/Downloads/VMManager/ovmm-3.4.5-installer-OracleLinux-b1919.iso inflating: /home/loredata/Downloads/VMManager/README.html
Em seguida montamos a imagem ISO ovmm-3.4.5-installer-OracleLinux-b1919.iso que foi descompactada:
[root@vision ~]# mount /home/loredata/Downloads/VMManager/ovmm-3.4.5-installer-OracleLinux-b1919.iso /mnt mount: /dev/loop0 is write-protected, mounting read-only
Conferimos os arquivos dentro da ISO:
[root@vision ~]# cd /mnt [root@vision mnt]# ls -lh total 151M -rw-r--r--. 1 root root 4.1M May 30 19:33 OvmSDK_3.4.5.1919.zip -r--r--r--. 1 root root 1.6K May 30 19:37 TRANS.TBL drwxr-xr-x. 7 root root 8.0K May 30 19:37 components -r-xr-x---. 1 root root 12K May 30 19:36 createOracle.sh -rw-r--r--. 1 root root 230 May 30 19:36 oracle-validated.params -r-xr-x---. 1 root root 147M May 30 19:37 ovmm-installer.bsx -r-xr-x---. 1 root root 1.9K May 30 19:37 runInstaller.sh -rw-r--r--. 1 root root 372 May 30 19:37 sample.yml
Ainda com o usuário root executamos o script createOracle.sh. Este script criará o usuário oracle e o grupo dba, a partição /u01 e também ajustará o parâmetros de memória no arquivo /etc/security/limits.conf e também ajustará as portas que devem ser abertas no arquivo /etc/sysconfig/iptables.
Antes de executar vamos confirmar que o serviço do iptables está ativo:
[root@vision mnt]# systemctl status iptables Unit iptables.service could not be found.
Veja que o serviço iptables não existe.
Vamos confirmar se o Firewall está ativo:
[root@vision mnt]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2018-10-09 19:10:50 -03; 31min ago
Docs: man:firewalld(1)
Main PID: 803 (firewalld)

Oct 09 19:10:50 vision.loredata.com.br systemd[1]: Started firewalld - dynamic firewall daemon.
OK, vamos executar o script createOracle.sh:
[root@vision mnt]# ./createOracle.sh Missing required package, Oracle VM Manager requires 'iptables-services' to be installed, you can use 'yum install iptables-services' to install it.
Veja que é pré-requisito que o iptables esteja instalado. Então vamos instalá-lo:
[root@vision mnt]# yum install iptables-services Failed to set locale, defaulting to C Loaded plugins: langpacks, ulninfo ol7_UEKR4 | 1.2 kB 00:00:00 ol7_latest | 1.4 kB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package iptables-services.x86_64 0:1.4.21-24.1.el7_5 will be installed --> Processing Dependency: iptables = 1.4.21-24.1.el7_5 for package: iptables-services-1.4.21-24.1.el7_5.x86_64 --> Running transaction check ---> Package iptables.x86_64 0:1.4.21-24.el7 will be updated ---> Package iptables.x86_64 0:1.4.21-24.1.el7_5 will be an update --> Finished Dependency Resolution Dependencies Resolved ========================================================================================================================================================================================= Package Arch Version Repository Size ========================================================================================================================================================================================= Installing: iptables-services x86_64 1.4.21-24.1.el7_5 ol7_latest 51 k Updating for dependencies: iptables x86_64 1.4.21-24.1.el7_5 ol7_latest 431 k Transaction Summary ========================================================================================================================================================================================= Install 1 Package Upgrade ( 1 Dependent package) Total size: 482 k Total download size: 51 k Is this ok [y/d/N]: y Downloading packages: iptables-services-1.4.21-24.1.el7_5.x86_64.rpm | 51 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Updating : iptables-1.4.21-24.1.el7_5.x86_64 1/3 Installing : iptables-services-1.4.21-24.1.el7_5.x86_64 2/3 Cleanup : iptables-1.4.21-24.el7.x86_64 3/3 Verifying : iptables-services-1.4.21-24.1.el7_5.x86_64 1/3 Verifying : iptables-1.4.21-24.1.el7_5.x86_64 2/3 Verifying : iptables-1.4.21-24.el7.x86_64 3/3 Installed: iptables-services.x86_64 0:1.4.21-24.1.el7_5 Dependency Updated: iptables.x86_64 0:1.4.21-24.1.el7_5 Complete!
Executamos novamente o script createOracle.sh:

Rules added.
Podemos observar que o script fez várias alterações no nosso ambiente, então precisamos ter certeza de como isso afetará o servidor e demais serviços dependentes desse servidor onde estamos instalando o OVM Manager.
Uma coisa que o script não faz é ajustar o /etc/hosts, então precisamos fazer isso manualmente:
[root@vision ~]# vi /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.118.103 vision.loredata.com.br vision
Um último ponto antes de iniciarmos a instalação… Este é um Oracle Linux 7.5, então ele vem com alguns pacotes do Maria DB instalados (irônico né? ), é necessário remover estes pacotes antes de seguir com a instalação do OVM Manager:
[root@vision mnt]# yum remove mariadb-libs Failed to set locale, defaulting to C Loaded plugins: langpacks, ulninfo Resolving Dependencies --> Running transaction check ---> Package mariadb-libs.x86_64 1:5.5.56-2.el7 will be erased --> Processing Dependency: libmysqlclient.so.18()(64bit) for package: 2:postfix-2.10.1-6.0.1.el7.x86_64 --> Processing Dependency: libmysqlclient.so.18(libmysqlclient_18)(64bit) for package: 2:postfix-2.10.1-6.0.1.el7.x86_64 --> Running transaction check ---> Package postfix.x86_64 2:2.10.1-6.0.1.el7 will be erased --> Finished Dependency Resolution Dependencies Resolved ========================================================================================================================================================================================= Package Arch Version Repository Size ========================================================================================================================================================================================= Removing: mariadb-libs x86_64 1:5.5.56-2.el7 @anaconda/7.5 4.4 M Removing for dependencies: postfix x86_64 2:2.10.1-6.0.1.el7 @anaconda/7.5 12 M Transaction Summary ========================================================================================================================================================================================= Remove 1 Package (+1 Dependent package) Installed size: 17 M Is this ok [y/N]: y Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Erasing : 2:postfix-2.10.1-6.0.1.el7.x86_64 1/2 Erasing : 1:mariadb-libs-5.5.56-2.el7.x86_64 2/2 Verifying : 1:mariadb-libs-5.5.56-2.el7.x86_64 1/2 Verifying : 2:postfix-2.10.1-6.0.1.el7.x86_64 2/2 Removed: mariadb-libs.x86_64 1:5.5.56-2.el7 Dependency Removed: postfix.x86_64 2:2.10.1-6.0.1.el7 Complete!
Partimos agora para a instalação do Software do Oracle VM Manager em si. Durante o processo de instalação um prompt vai aguardar a entrada de algumas informações para proceeder com a instalação. Para instalar o OVM Manager isso executamos com o usuário root o script runInstaller.sh e provemos as entradas necessárias nos prompts:

For more information about Oracle Virtualization, please visit: http://www.oracle.com/virtualization/ As of Oracle VM Release 3.4.5, the TLSv1.2 protocol is used for all connections and management of 3.2.10/11 servers is not possible by default. TLSv1 protocol must be enabled, which is less secure. For instructions, see the Oracle VM 3.4 Installation and Upgrade guide. Oracle VM Manager installation complete. Please remove configuration file /tmp/ovm_configgnwe_q.
Instalação finalizada com sucesso!
Além das portas, links e usuários mencionados ao final da instalação também temos as seguintes informações importantes sobre esse ambiente:
Para gerenciar os serviços que compõem o OVM Manager usamos o utilitário service (ou systemctl) do Linux.
Para verificar se o OVM Manager está rodando:
[root@vision ~]# service ovmm status Oracle VM Manager is running...
Para parar o OVM Manager:
[root@vision ~]# service ovmm stop Stopping ovmm (via systemctl): [ OK ]
E para iniciar o OVM Manager:
[root@vision ~]# service ovmm start Starting ovmm (via systemctl): [ OK ]
Para acessar a página de administração é só abrir no browser o link informado ao final da instalação e entrar com o usuário admin e credenciais também informadas durante a instalação:
