This guide explains how to install OpenManage on CentOS7 systems
...
, CentOS8-Stream and AlmaLinux9 systems
The following instructions are integrated in the script that could be found at: cld-foreman:/root/misc-utilsrepo/dell-om-install-<versione_date>.sh Please update it accordingly in the event that the instructions need to be revised
Enable crb repo (this should be needed only on AlmaLinux9):
| Code Block |
|---|
|
yum install yum-utils
/usr/bin/yum-config-manager --enable crb
yum clean all |
Install latest repo
| Code Block |
|---|
|
yum -y install perl
wget -q -O -script.sh http://linux.dell.com/repo/hardware/dsu/bootstrap.cgi | bash
sh script.sh |
We now install the srvadmin-all metapackage alongside with dependencies and other needed packages
...
| Code Block |
|---|
|
cd /opt/dell/srvadmin/etc/openmanage/oma/ini/
grep "preferences.system.smtp" oma.properties
if [ $? -eq 0 ]; then
sed -i 's/^preferences.system.smtp=.*/preferences.system.smtp=smtp.pd.infn.it/' oma.properties
else
echo "preferences.system.smtp=smtp.pd.infn.it" >> oma.properties
fi |
Edit
Setup DNS suffix
| Code Block |
|---|
|
cd /opt/dell/srvadmin/etc/openmanage/oma/ini/ |
...
grep "preferences.system.dnssuffix" oma.properties |
...
...
sed -i 's/^preferences.system.dnssuffix=.*/preferences.system.dnssuffix=pd.infn.it/' oma.properties |
...
else
echo "preferences.system.dnssuffix=pd.infn.it" >> oma.properties |
...
Edit
Setup snmp daemon
| Code Block |
|---|
|
sed -i.ORIG 's/^syslocation .*/syslocation Sala CED @ DFA Padova/' /etc/snmp/snmpd.conf |
...
echo "# Allow Systems Management Data Engine SNMP to connect to snmpd using SMUX" >> /etc/snmp/snmpd.conf |
...
echo "smuxpeer .1.3.6.1.4.1.674.10892.1" >> /etc/snmp/snmpd.conf |
...
echo "view all included .1" >> /etc/snmp/snmpd.conf |
we must override this previous access rule:
| Code Block |
|---|
|
grep -e '^access.*notConfigGroup' /etc/snmp/snmpd.conf |
...
...
sed -i 's/^access.*notConfigGroup/#access.*notConfigGroup/' /etc/snmp/snmpd.conf |
...
...
echo "access notConfigGroup \"\" any noauth exact all none none" >> /etc/snmp/snmpd.conf |
Edit
Enable and fire up the needed services
| Code Block |
|---|
|
systemctl start ipmi |
...
...
...
...
/opt/dell/srvadmin/sbin/srvadmin-services.sh enable |
...
/opt/dell/srvadmin/sbin/srvadmin-services.sh enable dsm_sa_snmpd |
...
/etc/init.d/dataeng enablesnmp |
...
/opt/dell/srvadmin/sbin/srvadmin-services.sh start |
Finally open needed ports on client firewall:
...
...
firewall-cmd --add-port=${i} |
...
firewall-cmd --permanent --add-port=${i} |
...
...
...
