OCS Agent installation on linux servers

First , Install these modules :-

CentOS/OEL :

yum install -y perl-XML-Simple perl-Compress-Zlib perl-Net-IP perl-LWP perl-Digest-MD5 perl-Net-SSLeay

yum install -y perl-Crypt-SSLeay perl-Net-SNMP perl-Proc-Daemon perl-Proc-PID-File perl-Sys-Syslog pciutils smartmontools monitor-edid

RHEL 4 :

up2date install  perl-XML-Simple perl-Compress-Zlib perl-Net-IP perl-LWP perl-Digest-MD5 perl-Net-SSLeay

up2date install -y perl-Crypt-SSLeay perl-Net-SNMP perl-Proc-Daemon perl-Proc-PID-File perl-Sys-Syslog pciutils smartmontools monitor-edid

up2date --register

up2date up2date

rpm -qa | grep up2date

 Note: RHEL upgrade with  OEL repo . Run these commands 

Converting RHEL To OEL YUM

 cd /etc/yum.repos.d

wget  http://public-yum.oracle.com/public-yum-ol6.repo

 yum repolist

Might give an error Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle

To resolve this use the following command

 rpm --import  https://oss.oracle.com/ol6/RPM-GPG-KEY-oracle

rpm --import /usr/share/rhn/RPM-GPG-KEY

 rpm -q gpg-pubkey-ec551f03-4c2d256a

After the updates are complete system might start throwing a CERT Error
