1) Install and enable EPEL
sudo wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install epel-release-latest-7.noarch.rpm
Tip:
To list all available packages under a repo called epel, enter:
$ sudo yum --disablerepo="*" --enablerepo="epel" list available
2) Install graphite related packages
sudo yum install -y graphite-web python-carbon
3) Modify storage schema file
sudo nano /etc/carbon/storage-schemas.conf
[default]
pattern= .*
retentions = 12s:4h, 2m:3d, 5m:8d, 13m:32d, 1h:1y
Now, restart carbon:
sudo service carbon-cache restart
OR
sudo systemctl enable carbon-cache
sudo systemctl start carbon-cache
4) Modify some settings in django graphite web application file:
sudo nano /etc/graphite-web/local_settings.py
# line 13: uncomment and specify any secret-key you like
SECRET_KEY = 'my_secret_key'
# line 23: uncomment and change to your timezone
TIME_ZONE = 'Asia/Calcutta'
5) Now, create django superuser and create database.
/bin/graphite-manage syncdb
Enter required user/password for superuser etc in the interactive session.
6) Configure apache for graphite:
Remove the default index page from apache:
echo > /etc/httpd/conf.d/welcome.conf
Next, edit /etc/httpd/conf.d/graphite-web.conf and replace everything in the 'Directory "/usr/share/graphite/"' block with:
Require all granted
Order allow,deny
Allow from all
Check if proper permissions to the Graphite directory:
sudo chown apache:apache /var/lib/graphite-web/graphite.db
permission should be: -rw-r--r-- and owner:apache:apache
And work around a bug related to building indexs with:
touch /var/lib/graphite-web/index
permission should be: -rw-r--r-- and owner:root:root
Start Apache and enable auto-start:
sudo systemctl start httpd
sudo systemctl enable httpd
7) If firewall is enabled, allow port 80 access.
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --reload
