Download Observium
First, create a directory for Observium to live in:
mkdir -p /opt/observium && cd /opt

Download the latest .tar.gz of Observium and unpack:
wget http://www.observium.org/observium-community-latest.tar.gz
tar zxvf observium-community-latest.tar.gz
MySQL Database
Start MySQL/MariaDB and configure it to be run at startup.
systemctl enable mariadb
systemctl start mariadb
Set the MySQL root password:
/usr/bin/mysqladmin -u root password ‘password’
SHOW GLOBAL VARIABLES LIKE ‘version’;
Create the MySQL database:
mysql -u root -p
CREATE DATABASE observium DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER ‘observium’@’localhost’ IDENTIFIED BY ‘password’;
GRANT ALL PRIVILEGES ON observium.* TO ‘observium’@’localhost’;
FLUSH PRIVILEGES;
exit;
Observium Configuration
Change into the new install directory:
cd observium
Copy the default configuration file and edit it for your system:
cp config.php.default config.php
You must change the MySQL username and password
Insert MySQL Schema
Run the discovery.php script with the upgrade switch -u in order to insert the initial MySQL schema
./discovery.php -u

Fping
Since Fping is in a different location, add a line to config.php to tell Observium.
[root@ipcon]# which fping
/sbin/fping
Add the following under nano/opt/observium/config.php
$config[‘fping’] = “/sbin/fping”;
cd /opt/observium
mkdir rrd
Next, grant Apache ownership to ‘rrd‘ directory to write and store RRD’s under this directory.
chown -R apache:apache rrd
To maintain observium logs, create a ‘logs‘ directory for Apache under ‘/opt/observium‘ and apply Apache ownership to write logs.
mkdir /opt/observium/logs
chown apache:apache /opt/observium/logs
Create a Apache Virtual Host directive for Obervium in ‘/etc/httpd/conf.d/httpd.conf‘ file.
nano /etc/httpd/conf.d/observium.conf
Add the following Virtual Host directive at the bottom of the file and enable Virtualhost section as shown in the screenshot below.
Default port 80 I made change 80 to 8008 fo apache web server
Set time zone in php.ini file.
For CentOS / RHEL: /etc/php.ini
After all settings, restart Apache service.
service httpd restart
Add a first user, use level of 10 for admin:
cd /opt/observium
i.e
./adduser.php admin admin@123 10
Configure snmpd
cp /opt/observium/snmpd.conf.example /etc/snmp/snmpd.conf
vi /etc/snmp/snmpd.conf
Cron
Add cron jobs, create a new file /etc/cron.d/observium with the following contents
Permit HTTP through the server’s default firewall
firewall-cmd –permanent –zone=public –add-service=http
firewall-cmd –add-port=8008/tcp –permanent
firewall-cmd –reload
Add a first device to monitor:
./add_device.php 192.168.88.126 observium v2c
Do an initial discovery and polling run to populate the data for the new device:

./poller.php -h all
