# Certificate
|
|
|
|
Certificates are used to certify that your server is the genuine one, and not an attacker trying to impersonate it.
|
|
|
|
YunoHost provides a **self-signed** certificate, it means that your server guaranties the certificate validity. It's enough **for personal usage**, because you trust your own server. But this could be a problem if you want to open access to anonymous like web user for a website.
|
|
|
|
In practice, visitors will see a screen list this:
|
|
|
|
<img src="/images/postinstall_error.png" style="max-width:100%;border-radius: 5px;border: 1px solid rgba(0,0,0,0.15);box-shadow: 0 5px 15px rgba(0,0,0,0.35);">
|
|
|
|
Which basically asks the visitor : **"Do you trust the server hosting this website?"**. This can rightfully frighten a lot of people.
|
|
|
|
To avoid this confusion, it's possible to get a certificate signed a known
|
|
authority named **Let's Encrypt** which provide free certificates directly
|
|
recognized by browsers. YunoHost allows to directly install this certificate
|
|
from the web administration interface or from the command line.
|
|
|
|
### Install a Let's Encrypt certificate
|
|
|
|
Before attempting to install a Let's Encrypt certificate, you should make sure
|
|
that your DNS is correctly configured (votre.domaine.tld should point to
|
|
your server's IP) and that your domain is accessible though HTTP from outside
|
|
your local network (i.e. at least port 80 should be forwarded to your server).
|
|
|
|
#### From the web administration interface
|
|
|
|
Go to the 'Domain' part of the admin interface, then in the section dedicated to
|
|
your.domain.tld. You should find a 'SSL certificate' button :
|
|
|
|
|
|
|
|
In the 'SSL certificate' section, you can see the status of the current
|
|
certificate. If you just added the domain, it should be a self-signed
|
|
certificate.
|
|
|
|
|
|
|
|
If your domain is correctly configured, it is then possible to install the
|
|
Let's Encrypt certificate via the green button.
|
|
|
|
|
|
|
|
Once the install is made, you can check that the certificate is live via your
|
|
browser by going to your domain in HTTPS. The certificate will automatically
|
|
be renewed every three months.
|
|
|
|
|
|
|
|
#### From the command line interface
|
|
|
|
Connect to your server through SSH.
|
|
|
|
You can check the status of your current certificate with :
|
|
|
|
```bash
|
|
yunohost domain cert-status your.domain.tld
|
|
```
|
|
|
|
Install a Let's Encrypt certificate with
|
|
|
|
```bash
|
|
yunohost domain cert-install your.domain.tld
|
|
```
|
|
|
|
This should return :
|
|
|
|
```bash
|
|
Success! The SSOwat configuration has been generated
|
|
Success! Successfully installed Let's Encrypt certificate for domain DOMAIN.TLD!
|
|
```
|
|
|
|
Once this is done, you can check that the certificate is live via your
|
|
browser by going to your domain in HTTPS. The certificate will automatically
|
|
be renewed every three months.
|
|
|
|
##### Troubleshooting
|
|
|
|
If due to some bad tweaking, your certificate ends up in a bad state (e.g.
|
|
lost the certificate or unable to read the files), you should be able to clean
|
|
the situation by regenerating a self-signed certificate :
|
|
|
|
```bash
|
|
yunohost domain cert-install your.domain.tld --self-signed --force
|
|
```
|
|
|
|
If YunoHost thinks that your domain is badly configured despite the fact that
|
|
you checked the DNS configuration and you have access in HTTP to your server
|
|
from outside your local network, then you can :
|
|
|
|
- add a line `127.0.0.1 your.domain.tld` to the file `/etc/hosts` on your server ;
|
|
- if the certificate installation still doesn't work, you can disable the checks with `--no-checks` after the `cert-install` command.
