Grafana Installation\OracleLinux

Overview

Grafana Installation on Oracle Linux 6.8

Network Config

If you installed the basic package, most likely the NIC is not configured for DHCP. try:

User ~ $ system-config-network

Once DHCP is configured, the next step is to restart the NIC.

User ~ $ ifdown eth0
User ~ $ ifup eth0
 
Determining IP information for eth0... done.
User ~ $ifconfig eth0

Make sure your hostname is defined in /etc/sysconfig/network

HOSTNAME=server.fqdn.com

Also for the network config, put your FQDN in the hosts file @ /etc/hosts

127.0.0.1   server.fqdn.com
::1   server.fqdn.com

connect on boot

By default the network interface comes turned off on boot.

~$ sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:0c:29:4f:09:c8
TYPE=Ethernet
UUID=5eed1f7e-74da-4841-b03b-3d4cc0812ade
ONBOOT=no
NM_CONTROLLED=yes
BOOTPROTO=dhcp
USERCTL=no
PEERDNS=yes
IPV6INIT=no

Change it so it automatically starts and connects on boot

ONBOOT=yes

Sudoers Config

Personally I prefer to use a group for sudoer management. Specify a unique UID so that it will be the same on all servers (manually dictate).

# groupadd -g <unique UID> sudo

Now we can add the group to the sudoers file

# visudo
Add the following under the entry for root

## Allows members of the 'sudo' group to run all commands anywhere
%sudo     ALL=(ALL)          ALL

Add new user(s) and make them a part of the new sudo group

# useradd -G sudo -u <unique UID> user_a

Change the password of the user

# passwd <username>

SSH Config

With Oracle Linux 6.8, openssh should be installed by default, but if it isnt:

#yum install openssl openssh-server

Grafana Repo

Create a new repo file for grafana

~$ sudo vi /etc/yum.repos.d/grafana.repo
Add:
[grafana]
name=grafana
baseurl=https://packagecloud.io/grafana/stable/el/6/$basearch
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packagecloud.io/gpg.key https://grafanarel.s3.amazonaws.com/RPM-GPG-KEY-grafana
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt

Update repo cache ~$ sudo yum makecache
