Automating rhev manager installation

First installation ,the –generate-answer flag needs to be passed:

#engine-setup --generate-answer=/root/answers.txt

--config-append=file

#engine-setup –config-append=/root/answers.txt

Applying release updates

A list of locked packages can be found in /etc/yum/pluginconf.d/versionlock.list

Rhev manager updates by using engine-upgrade-check

#engine-upgrade-check

#yum update –y engine-setup

Ptrctice :page37

Manageing users,roles,and permissions

Use engine-manage-domains command to bind to a directory service:

#engine-manage-domains add --domain=DOMAIN --user=USER --provider=PROVIDER

Roles:UserRole,UserVmManager,TemplateBaseVm,SuperUser,ClusterAdmin,StorgeAdmin,Host

Troubleshooting rhev manager

Firewall configuration

#cat /et c/ovirt-engine/iptables.example

Confirmin the system time

#service ntpd stop

#ntpdate classroom.example.com

#hwclock –w

#hwclock

#service ntpd start

Internal administrative account

1.log in as root omn the rhev-m linuex server.

2.user the engine-config –s AdminPassword=interactive to reset the internal

administrative password.

#engine-config –s AdminPassword=interactive

3. service ovirt-engine restart

Demonstration:
#grep server /etc/ntp.conf

Retrieving rhev configuration values with rhev configuration tool;

Update a value ,the –s flag needs to be used.

#engine-config –s “UserDefinedVMproperties=macspoof=(true

flase)”

Use engine-config –a to retrieve all existing values:

#engine-congfig-a

JBoss is restart and restart the ovirt-engine service:

#engine-config –g “AuditLogCleanupTime”

Pass a configuration file as an argument:

#engine-config –s PasswordEntry --admin-pass-file=/tmp/mypass

Demonstration:

Reading the log files

Grep to look for specific errors :

#grep ERROR /var/log/ovirt-engine/engie.log

Usging log collector

The command output will be saved in the /tmo/logcollector

Engine-log-collector [options] list [all,clusters,datacenters]

Options can be persistently specified by making changes to the

/etc/rhevm/logcollector.conf file.

Backing up and resoring rhev

Backing uo red hat enterprise virtualization mangager

1. Ssh root@rhevm

2. Stop the ovirt-engine-dwhd daemon:

[root@rhevm ~]# service ovirt-engine-dwhd stop

Stopping oVirt Engine Dataware House: [ OK ]

3. Create the full backup:

[root@rhevm ~]# engine-backup --scope=all --mode=backup --log=/root/backup.log --
file=/root/rhev-backup.tar

Engine-backup command works in one of two basic modes:

#engine-backup –mode=backup

#engine-backuo –mode=restore

Demonstration : backing up red hat enterprise virtualization manager page272

1. from the desktop.exmple.com,open a shell ,and SSH into the rhev-m server:

#ssh root@rhevm.podX.example.com

2. before backing up,make sure to stop the ovirt-engine-dwhd deamon:

#service ovirt-engine-dwhd stop

3. once logged in ,run the following command to create a full backup:

#engine-backup –scope=all --mode=backup --log=/root/backup.log --file=/root/rhev-

backup.tar

4. the database are called engine and ovirt_engine_history for rhev-m ,and
rhevmreports for thev-m reports.

#engine-backup --scope=db --mode=backup --log=[file name] --file =[file name]

Restorying the red hat enterprise virtualization manager database

1. log onto eh manchine on which the red hat enterprise virulization manager is
installed.

2. Create empty database to which the database in the backup can be restored and
configure the postgresql service:

#service postgresql initdb

#service postgresql start

#chkconfig postgresql on

Run the following commands to enter the postgresql command line:

#service postgresql initdb

#su postgres

$psql

Run the following command to create a new user:

Postgres=#create role [user name ] with login encrypted password ‘[password]’;

Run the following command to create the new database:

Postgres=#create database [database name] owner [user name] template template0

encoding ‘UTF8’ lc_collate ‘en_US.UTF-8’ lc_ctype ‘en_UTF-8’;

Edit the /var/lib/psql/data/pg_hda.conf file as follows:

#service postgresql restart

3. restore the backuo using the engine-backuo command tiwh the –change-db-
credentials parameter to pass th credentials of the new database:

#engine-backuo –mode=restore –file=[file name] –log=[file name] –log=[file name] –

change-db-credentials –db-host=[databse location] –db-name=[database name] –db-
user=[user name] --db-password=[password]

4. configure the engine prompts:

engine-setup

5. engine databse and configuration file for the red hat enterprise vitualization
manager have been restored to the version in the backup;

rhev-m reinstallation

#service ovirt-engine stop

#yum remove rhevm rhevm rhevm-dwh rhevm-reports

#rm –rf /etc/pki/ovirt-engine

#rm –rf /etc/ovirt-engine

#yum –y install rhevm rhevm-dwh rhevm-reports

#engine-setup using the –config-append flag ,in order to user answer file,

#engine-setup –config-append=-/root/answers.txt

Practice backuping up and restoting rhev page 277

1. log onto the machine that red hat enterprise virtualization manager is installed

2. run the followindg command ,and the prompts to remove the configuration files
for and clean the databases associated with the manager:

3. restore the backup using the engine-backup command:

3. subscribe the system to the redha enterprise virtualization management agent(V7

x86_64) channel on rhn

#wget http://classroom.example.com/materials/r

4. install the vdsm package using yum

#yum install –y vdsm

5. add an entry fir the rhev-m machine to /etc/host so the hypervisor can always
find the rhev-m machine

#echo ‘172.25.x.15 rhevm.podx.example.com rhevm’ >>/etc/hosts

6. disable the networkManager service

#systemctl stop NetworkManager

#systemctl disable NetworkManager

#systemctl enable network
