openssl pkcs12 -in domain.pfx -clcerts -nokeys -out domain.cer openssl pkcs12 -in domain.pfx -nocerts -nodes -out domain.key I also generated Certificate Authority (CA) certificate: openssl pkcs12 -in domain.pfx -out domain-ca.crt -nodes -nokeys -cacerts And included it in Apache config file: <VirtualHost 192.168.0.1:443> ... SSLEngine on SSLCertificateFile /path/to/domain.cer SSLCertificateKeyFile /path/to/domain.key SSLCACertificateFile /path/to/domain-ca.crt ... </VirtualHost> Ou pode converter em .crt e .key, abrir o .crt e deixar apenas o primeiro certificado, recorte os demais certificados do .crt e cole em um novo arquivo chamado .chain, as configurações devem ficar parecidas como as de baixo: <VirtualHost *:443> ServerAdmin admin@winspire.com.br ServerName winspire.com.br SSLEngine on SSLCertificateKeyFile /etc/httpd/ssl/winspire.com.br.key SSLCertificateFile /etc/httpd/ssl/winspire.com.br.crt SSLCertificateChainFile

Movendo LVM para outro sistema Linux. 1 – Desmontar o file system Inicialmente devemos desmontar os sistemas de arquivos que estão sob o VG que será migrado. Assim, você garante que nada tentará escrever na área que será movimentada. # unmount /data/www 2 – Mark the volume group inactive Vamos marcar o VG como inativo removendo ele do kernel, isso é para prevenirmos que quaisquer atividades tentem ativá-lo novamente. # vgchange -an webdata vgchange — volume group “webdata” successfully deactivated 3 – Exportar o VG It is now necessary to export the volume group. This prevents it from being accessed on the “old” host system and prepares it to be removed. Nesta etapa é necessário exportar o VG para ser levado ao novo servidor. O servidor antigo também “fica preparado” para sua remoção. # vgexport webdata vgexport — volume group “webdata” successfully exported Na próxima vez que o sistema operacional for reiniciado, os discos poderão dês desconectados e
