Deployment

There are several options available, depending on your setup.

Gunicorn + nginx

First, you need to install Gunicorn. The easiest way is to use pip:

$ pip install gunicorn

If you have installed Graphite-API in a virtualenv, install Gunicorn in the same virtualenv:

$ /usr/share/python/graphite/bin/pip install gunicorn

Next, create the script that will run Graphite-API using your process watcher of choice.

Upstart

description "Graphite-API server"
start on runlevel [2345]
stop on runlevel [!2345]

respawn

exec gunicorn -w2 graphite_api.app:app -b 127.0.0.1:8888

Supervisor

[program:graphite-api]
command = gunicorn -w2 graphite_api.app:app -b 127.0.0.1:8888
autostart = true
autorestart = true

systemd

# This is /etc/systemd/system/graphite-api.socket
[Unit]
Description=graphite-api socket

[Socket]
ListenStream=/run/graphite-api.sock
ListenStream=127.0.0.1:8888

[Install]
WantedBy=sockets.target
# This is /etc/systemd/system/graphite-api.service
[Unit]
Description=Graphite-API service
Requires=graphite-api.socket

[Service]
ExecStart=/usr/bin/gunicorn -w2 graphite_api.app:app
Restart=on-failure
#User=graphite
#Group=graphite
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

Note

If you have installed Graphite-API and Gunicorn in a virtualenv, you need to use the full path to Gunicorn. Instead of gunicorn, use /usr/share/python/graphite/bin/gunicorn (assuming your virtualenv is at /usr/share/python/graphite).

See the Gunicorn docs for configuration options and command-line flags.

Finally, configure the nginx vhost:

# /etc/nginx/sites-available/graphite.conf

upstream graphite {
    server 127.0.0.1:8888 fail_timeout=0;
}

server {
    server_name graph;
    listen 80 default;
    root /srv/www/graphite;

    location / {
        try_files $uri @graphite;
    }

    location @graphite {
        proxy_pass http://graphite;
    }
}

Enable the vhost and restart nginx:

$ ln -s /etc/nginx/sites-available/graphite.conf /etc/nginx/sites-enabled
$ service nginx restart

Apache + mod_wsgi

First, you need to install mod_wsgi.

See the mod_wsgi InstallationInstructions for installation instructions.

Then create the graphite-api.wsgi:

# /var/www/wsgi-scripts/graphite-api.wsgi

from graphite_api.app import app as application

Finally, configure the apache vhost:

# /etc/httpd/conf.d/graphite.conf

LoadModule wsgi_module modules/mod_wsgi.so

WSGISocketPrefix /var/run/wsgi

Listen 8013
<VirtualHost *:8013>

    WSGIDaemonProcess graphite-api processes=5 threads=5 display-name='%{GROUP}' inactivity-timeout=120
    WSGIProcessGroup graphite-api
    WSGIApplicationGroup %{GLOBAL}
    WSGIImportScript /var/www/wsgi-scripts/graphite-api.wsgi process-group=graphite-api application-group=%{GLOBAL}

    WSGIScriptAlias / /var/www/wsgi-scripts/graphite-api.wsgi

    <Directory /var/www/wsgi-scripts/>
        Order deny,allow
        Allow from all
    </Directory>
    </VirtualHost>

Adapt the mod_wsgi configuration to your requirements.

See the mod_wsgi QuickConfigurationGuide for an overview of configurations and mod_wsgi ConfigurationDirectives to see all configuration directives

Restart apache:

$ service httpd restart

Docker

Create a graphite-api.yaml configuration file with your desired config.

Create a Dockerfile:

FROM brutasse/graphite-api

Build your container:

docker build -t graphite-api .

Run it:

docker run -t -i -p 8888:8888 graphite-api

/srv/graphite is a docker VOLUME. You can use that to provide whisper data from the host (or from another docker container) to the graphite-api container:

docker run -t -i -v /path/to/graphite:/srv/graphite -p 8888:8888 graphite-api

This container has all the :ref:`extra packages <extras>` included. Cyanite backend and Sentry integration are available.

Nginx + uWSGI

First, you need to install uWSGI with Python support. On Debian, install uwsgi-plugin-python.

Then create the uWSGI file for Graphite-API in /etc/uwsgi/apps-available/graphite-api.ini:

[uwsgi]
processes = 2
socket = localhost:8080
plugins = python27
module = graphite_api.app:app

If you installed Graphite-API in a virtualenv, specify the virtualenv path:

home = /var/www/wsgi-scripts/env

If you need a custom location for Graphite-API's config file, set the environment variable like this:

env = GRAPHITE_API_CONFIG=/var/www/wsgi-scripts/config.yml

Enable graphite-api.ini and restart uWSGI:

$ ln -s /etc/uwsgi/apps-available/graphite-api.ini /etc/uwsgi/apps-enabled
$ service uwsgi restart

Finally, configure the nginx vhost:

# /etc/nginx/sites-available/graphite.conf

server {
    listen 80;

    location / {
        include uwsgi_params;
        uwsgi_pass localhost:8080;
    }
}

Enable the vhost and restart nginx:

$ ln -s /etc/nginx/sites-available/graphite.conf /etc/nginx/sites-enabled
$ service nginx restart

Other deployment methods

They currently aren't described here but there are several other ways to serve Graphite-API:

  • nginx + circus + chaussette
