Select the hardware on which you want install YunoHost :
If your host OS is 32 bits, be sure to download the 32-bit image.
If you wish to check the validity of our signed images, you can download our public key.
Now that you downloaded the image of YunoHost, you should flash it on a USB stick or a CD/DVD.
Download Etcher for your operating system and install it.
Plug your USB stick, select your image and click "Flash"
Download USBimager for your operating system and install it.
Plug your USB stick, select your image and click "Write"
If you are on GNU/Linux / macOS and know your way around command line, you may also flash your USB stick or SD card with
dd. You can identify which device corresponds to your USB stick or SD card with
fdisk -l or
lsblk. A typical SD card name is something like
/dev/mmcblk0. BE CAREFUL and make sure you got the right name.
Then run :
# Replace /dev/mmcblk0 if the name of your device is different... dd if=/path/to/yunohost.img of=/dev/mmcblk0
You should see a screen like this:
N.B.: Once you have validated the keyboard layout, the installation will be launched and will completely erase the data on your hard disk!
The YunoHost project simplified the classic installation as much as possible in order to avoid as many people as possible being lost with questions that are too technical or related to specific cases.
With the expert mode installation, you have more possibilities, especially concerning the exact partitioning of your storage media. You can also decide to use the classic mode and add your disks afterwards.
Expert graphical install.
In general, we recommend against partitioning
/root on separate partitions. This will prevent you from having to worry about full partitions that could crash your machine, cause app installations to fail, or even corrupt your databases.
For performance reasons, it is recommended to mount your fastest storage (SSD) on the root
If you have one or more hard drives to store data, you can choose to mount it on one of these folders depending on your usage.
||User folders accessible via SFTP|
||YunoHost backups to be placed ideally elsewhere than on the disks that manage the data|
||Heavy data from YunoHost applications (nextcloud, matrix...)|
||Heavy data shared between several applications|
If you want flexibility and don't want to (re)size partitions, you can also choose to mount on
/mnt/hdd and follow this tutorial to mount all these folders with
Be aware that if you encrypt all or part of your disks, you will have to type the passphrase every time you restart your server, which can be a problem if you are not on site. There are however solutions (quite difficult to implement) that allow you to type the passphrase via SSH or via a web page (search for "dropbear encrypted disk").
Keep in mind that:
If you are in the process of restoring a server using a YunoHost backup, you should skip this step and instead restore the backup instead of the postinstall step.
In an internet browser, type
yunohost-2.local, and so on if multiple YunoHost servers are on your network).
If this doesn't work, you can look for the the local IP address of your server. The address typically looks like
192.168.x.y, and you should therefore type
https://192.168.x.y in your browser's address bar.
During the first visit, you will very likely encounter a security warning related to the certificate used by the server. For now, your server uses a self-signed certificate. You will later be able to add a certificate automatically recognized by web browsers as described in the certificate documentation. For now, you should add a security exception to accept the current certificate. (Though, PLEASE, do not take the habit of blindly accepting this kind of security alert!)
You should then land on this page :
You can also perform the postinstallation with the command
yunohost tools postinstall directly on the server, or via SSH.
This will be the domain used by your server's users to access the authentication portal. You can later add other domains, and change which one is the main domain if needed.
If you're new to self-hosting and do not already have a domain name, we recommend using a .nohost.me / .noho.st / .ynh.fr (e.g.
homersimpson.nohost.me). Provided that it's not already taken, the domain will be configured automatically and you won't need any further configuration step. Please note that the downside is that you won't have full-control over the DNS configuration.
If you already own a domain name, you probably want to use it here. You will later need to configure DNS records as explained here.
Yes, you have to configure a domain name. If you don't have any domain name and don't want a .nohost.me / .noho.st / .ynh.fr either, you can set up a dummy domain such as
yolo.test and tweak your local
/etc/hosts file such that this dummy domain points to the appropriate IP, as explained here.
Since YunoHost 11.1, the first user is now created at this stage. You should pick a username and a reasonably complex password. (We cannot stress enough that the password should be robust!) This user will be added to the Admins group, and will therefore be able to access the user portal, the web admin interface, and connect via SSH or SFTP. Admins will also receive emails sent to
email@example.com : these emails may be used to send technical informations or alerts. You can later add additional users, which you can also add to the Admins group.
This user replaces the old
admin user, which some old documentation page may still refer to. In which case : just replace
admin with your username.
Once the postinstall is done, you should be able to actually log in the web admin interface using the credentials of the first user you just created.
The diagnosis system is meant to provide an easy way to validate that all critical aspects of your server are properly configured - and guide you in how to fix issues. The diagnosis will run twice a day and send an alert if issues are detected.
N.B. : don't run away ! The first time you run the diagnosis, it is quite expected to see a bunch of yellow/red alerts because you typically need to configure DNS records (if not using a
ynh.fr domain), add a swapfile if not enough ram and/or port forwarding.
If an alert is not relevant (for example because you don't intend on using a specific feature), it is perfectly fine to flag the issue as 'ignored' by going in the webadmin > Diagnosis, and clicking the ignore button for this specifc issue.
To run a diagnosis, go on Web Admin in the Diagnosis section. Click Run initial diagnosis and you should get a screen like this :
yunohost diagnosis run yunohost diagnosis show --issues --human-readable
Once you configured DNS records and port forwarding (if needed), you should be able to install a Let's Encrypt certificate. This will get rid of the spooky security warning from earlier for new visitors.
For more detailed instructions, or to lean more about SSL/TLS certificates, see the corresponding page here.
Go in Domains > Click on your domain > SSL Certificate
yunohost domain cert install
You now have a pretty well configured server. If you're new to YunoHost, we recommend to have a look at the guided tour. You should also be able to install your favourite applications. Don't forget to plan backups !
