This is designed to be what is called a "headless" installation, that is to be run on a Raspberry Pi without a monitor or keyboard attached to it. As such the image does not contain a Graphical User Interface (GUI), it is a command line only installation. It is possible to add the GUI later if you want it.
===Alternatives to using image===
Should you decide not to use the image, please see instructions in the support forum about [https://cumulus.hosiene.co.uk/viewtopic.php?f=44&t=18916 installing MX], about installing specifically on [https://cumulus.hosiene.co.uk/viewtopic.php?t=17895 Raspberry PI computer], and about installing on [https://cumulus.hosiene.co.uk/viewtopic.php?t=18766 any Linux computer].
=== Pre-Installation Steps ===
You will need:
* A suitable (micro) SD (high capacity) card for your Raspberry Pi
:A minimum size of 16GB is recommended. Be sure to buy a good quality card.
:You can use an SSD instead if preferred [with the minor complication that in a later step you will need non-WiFi access to the Raspberry Pi (keyboard and monitor, or SSH over ethernet) as you cannot enter the WiFi details from a Windows PC to the linux SSD
* An image installer to copy the image file to the SD card
:The [https://www.raspberrypi.org/documentation/installation/installing-images/ Raspberry Pi site] has a list of suitable software for your operating system. Scroll down to "Writing the image".<br />
: This guide uses Raspberry Pi Imager
* The image file to install
:Download the latest image file from the [[Software#Current_Release|Software Download page]], these are not produced for every MX release.
* An SSH terminal program to configure your Raspberry Pi
: For Windows we recommend using [https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html PuTTY]
:* Extracting the diagnostic files from Cumulus MX if this go wrong
:* Setting up a web site<br />
:A popular program for Windows is [https://winscp.net/eng/download.php WinSCP] which shares some configuration with PuTTY (but some people prefer FileZilla program and its interface).
=== Installing the Image ===
:* Save the file, and then rename it to '''wpa_supplicant.conf''' - i.e. remove the .txt filename extension<br /><br />
* Eject the SD card from your computer. Insert it into your Raspberry Pi and power up.
Please note, the edit above changes the country code for the wireless (WiFi) connection, the image is built on the basis that your Raspberry Pi will operate in the GB timezone, and MX will run using the GB locale. You can only modify those after installation is completed on your RPi computer.
=== First Boot ===
* Start your browser and see if you can connect to this URL: '''<nowiki>http://cumulusmx:8998</nowiki>'''
:* If you can great - you should now see the Cumulus MX console
:* If not, then you will have to find out the Raspberry Pi's IP address from your router. Then try connecting to this URL: '''http://<ip_address>:8998''' (example: '''<nowiki>http://192.168.1.123:8998</nowiki>''' where the numbers before :8998 are those for YOUR Raspberry Pi from YOUR router). It just depends on your router whether it allows use of the URL name (cumulusmx) or requires the IP address.
=== Verify your SSH Connection ===
:*; [[File:PuTTY-01.png|none]]
* You will have the accept the SSH key the first time you connect
* Enter the username "pi" and password (note UK spelling) "raspberry" - these are the default Raspberry Pi username credentials
* When you login it will display a warning about you using the default password and ask you to change it
:* Use the '''passwd''' command to do this now...
Retype new password:
passwd: password updated successfully</nowiki>
* Now you can check/configure your RPi for your locale and timezone settings.
* It's a good idea to check/configure your RPi for your locale and timezone settings. The default is for en_UK UTF-8 locale and GMT timezone. Use '''sudo raspi-config''' 5. Localization Options, L1 Locale (select en_US ISO-8851-1 for USA if needed) and L2 Timezone (select the appropriate timezone), then '''sudo reboot''' if needed to engage the new settings.▼
** ''The build has set a default which is for '''en_UK UTF-8''' locale and '''GMT''' timezone''.
▲*
* Check the status of the Cumulus MX service with the command '''sudo systemctl status cumulusmx'''<br />
: You will get some information back, the important bit to note is the line starting '''Active:''', it should say '''active (running)'''
== Additional Steps ==
''To be expanded''
* Configuring WiFi from SSH
** ''To be expanded''
* Stopping Cumulus MX starting up when the Pi boots
** The build sets up MX to run as a service, and to start when the computer builds, so it will be running when you switched your Raspberry Pi on
** To stop this auto-starting behavior permanently, just type <code>sudo systemctl disable cumulusmx</code> once.
* Give your Pi a fixed IP address
:* Add a DHCP reservation
''The line "dns-domain example.com" is optional''
:You could have also to edit
:see file «'''/etc/resolv.conf'''» to insert these lines:
nameserver 192.168.11.1
=== Install location ===
In this image Cumulus MX is installed into '''/opt/CumulusMX'''
If you have run MX before, you will copy your existing [[Cumulus.ini]], and optional [[Strings.ini]], into that folder. But be aware that MX has been set to run on boot, so MX will have started, and you must stop it with <code>sudo systemctl stop cumulusmx</code>, before you can add these files.
=== Symbolic Links ===
The image contains a number of pre-created symbolic links for Cumulus MX files such as realtime.txt and the standard website tmp files. These links divert these files to the random access memory chip (within the standard Linux folder "/run", the RAM storage area is configured as
The full list of symbolic links could be added here by another contributor, presumably these cover every .json file that is produced for the default web page with fully defaulted settings as to which files are produces. For the moment, two symbolic link examples are included below:
# sudo apt install raspberrypi-ui-mods
# sudo reboot
===Further Information===
There are two other pages in this Wiki that might be useful to read [[Raspberry Pi computer page]] and [[MX on Linux]].
=== systemctl commands ===
sudo systemctl stop cumulusmx
Then issue a change path command to move to the Cumulus folder and start
(Noting it is case sensitive).
* Copied full CMX download to /opt/CumulusMX folder
* Created symbolic links for temp files to /run/cumulusmx
The following commands are useful in creating the image file (created on Debian).
