Prerequisites¶
We need to prepare a couple of directories and create a database which is used by grafana.
Directory for storing the static files and default configuration:
[isabell@stardust ~]$ mkdir -p usr/share/grafana
[isabell@stardust ~]$
Directory for storing the custom configuration files:
[isabell@stardust ~]$ mkdir -p etc/grafana
[isabell@stardust ~]$
Directory for storing the log files:
[isabell@stardust ~]$ mkdir -p var/log/grafana
[isabell@stardust ~]$
Finally, create the mysql database for grafana:
[isabell@stardust ~]$ mysql -e "CREATE DATABASE isabell_grafana"
[isabell@stardust ~]$
Installation¶
Step 1¶
Find the latest version of grafana for the platform linux from the download page, download and extract it and enter the extracted directory:
[isabell@stardust ~]$ wget https://dl.grafana.com/oss/release/grafana-6.7.3.linux-amd64.tar.gz
[isabell@stardust ~]$ tar xvzf grafana-6.7.3.linux-amd64.tar.gz
[isabell@stardust ~]$ cd grafana-6.7.3
[isabell@stardust grafana-6.7.3]$
Step 2¶
Move the binary to ~/bin and the default configuration and html files to ~/usr/share/grafana.
[isabell@stardust grafana-6.7.3]$ mv bin/grafana-server ~/bin/
[isabell@stardust grafana-6.7.3]$ mv conf public ~/usr/share/grafana
[isabell@stardust grafana-6.7.3]$
Configuration¶
Configure web server¶
Note
grafana is running on port 3000.
To make the application accessible from the outside, configure a web backend:
[isabell@stardust ~]$ uberspace web backend set / --http --port <port>
Set backend for / to port <port>; please make sure something is listening!
You can always check the status of your backend using "uberspace web backend list".
[isabell@stardust ~]$
Setup grafana¶
Create the file ~/etc/grafana/grafana.ini with the following content:
[database]
type = mysql
host = 127.0.0.1:3306
name = isabell_grafana
user = isabell
# If the password contains # or ; you have to wrap it with triple quotes. Ex """#password;"""
password = "<mysql-password>"
[analytics]
reporting_enabled = false
check_for_updates = true
[security]
admin_user = admin
admin_password = password123
Note
The admin_password MUST later be changed via the web interface when grafana is running.
Setup daemon¶
Create the file ~/etc/services.d/grafana.ini with the following content:
[program:grafana]
command=grafana-server
-config %(ENV_HOME)s/etc/grafana/grafana.ini
-homepath %(ENV_HOME)s/usr/share/grafana
cfg:default.paths.logs=%(ENV_HOME)s/var/log/grafana
autostart=yes
autorestart=yes
What the arguments for grafana mean:
--config: The location of the custom configuration file we created.
--homepath: The location of the default configuration and the static files.
cfg:default.paths.logs: The location of the log files created by grafana.
Finishing installation¶
Start grafana¶
After creating the configuration, tell supervisord to refresh its configuration and start the service:
[isabell@stardust ~]$ supervisorctl reread
SERVICE: available
[isabell@stardust ~]$ supervisorctl update
SERVICE: added process group
[isabell@stardust ~]$ supervisorctl status
SERVICE RUNNING pid 26020, uptime 0:03:14
[isabell@stardust ~]$
Now point your browser at your uberspace and you should see the grafana web interface.
