Following are changes i have done in yocto mender build…  
local.conf

```auto
MENDER_DEMO_HOST_IP_ADDRESS = "10.42.0.223"
MENDER_SERVER_URL = "https://leshan.com"
FILESEXTRAPATHS_prepend_pn-mender := "/etc/apache2/ssl:"
SRC_URI_append_pn-mender = " file://leshan.crt"

```

mender.conf in receips-mender/mender/files\*\*/mender.conf\*\*

```auto
{
    "InventoryPollIntervalSeconds": 30,
    "RetryPollIntervalSeconds": 30,
    "RootfsPartA": "/dev/mmcblk0p2",
    "RootfsPartB": "/dev/mmcblk0p3",

    "ServerURL": "https://leshan.com",
    "TenantToken": "",
    "UpdatePollIntervalSeconds": 30

```

Following are my changes on device side while device up and running  
cat /etc/mender/mender.conf

```auto

Hi @ramu,

You seem to be mixing “demo environment” settings and with "production environment.

To better understand what you are trying to do, can please confirm which server instance are you using,

1. [https://docs.mender.io/1.7/getting-started/create-a-test-environment](https://docs.mender.io/1.7/getting-started/create-a-test-environment)

or

I used mender server from [https://docs.mender.io/1.7/getting-started/create-a-test-environment](https://docs.mender.io/1.7/getting-started/create-a-test-environment) and tested mender client on raspbery board using readily available images from mender site…

Then now, I am using the same above demo server which is running on my laptop ( Created certificate with [CN=leshan.com](http://CN=leshan.com) ) for mender client running on my solidrun board. I have made the above said changes like server name, certificate, ip address etc for in my yocto build for my device…

Above is all you need for the demo environment in your Yocto configuration.

You can remove this,

```auto
MENDER_SERVER_URL = "https://leshan.com"
FILESEXTRAPATHS_prepend_pn-mender := "/etc/apache2/ssl:"
SRC_URI_append_pn-mender = " file://leshan.crt"

```

We already provide “demo certificates” for usage with demo environment and you can not use custom keys/certificates in this case.

If i want to use demo server then what are the values i need to use for below attributes in mender.conf and etc/hosts??  
I think i can delete below lines or mender.conf in recipes-more/

“ServerCertificate”: “/etc/mender/leshan.crt”,  
“ServerURL”: “[https://leshan.com](https://leshan.com)”,

```auto
cat /etc/hosts 
127.0.0.1	localhost.localdomain localhost
10.42.0.1 leshan.com **Here** ( mender.io ??)

```

</div>

It should be:

```auto
10.42.0.1 docker.mender.io

```

But if you use the `MENDER_DEMO_HOST_IP_ADDRESS` variable in Yocto, it will set this up correctly

I have made the above said changes like server name, certificate, ip address etc for in my yocto build for my device…

Demo server will be same in any case except the IP address configuration on the client to access the server. The demo server certificate and other configurations will be ready when you add the `/meta-mender/meta-mender-demo` to your soldrun board. No extra settings are required apart from what @mirzak suggested.

If you plan to go for production with your own server and certificate, then you need to [remove](https://docs.mender.io/1.7/artifacts/yocto-project/building-for-production) this meta-mender-demo layer and configure it as per your settings. Taking the demo server and making it as production server will not work!

I hope this helps 🙂

To make sure that the server is clean and solid, can you please do the below steps to make it default?  
[https://docs.mender.io/1.7/getting-started/maintain-the-test-environment#clean-up-the-environment](https://docs.mender.io/1.7/getting-started/maintain-the-test-environment#clean-up-the-environment)

This will reset the mender server to it’s original state so that, your device then consider as a new one and fetch the inventory data (if decommission made issue).

Thanks Ajith and Mirzak… I am able to update my device with new releases using production server and client… As of now I am updating the /etc/hosts and systemd/network/eth.entwork using mender-artifact tool… I Specified below changes as well, still /etc/hosts not reflecting these changes…  
MENDER\_DEMO\_HOST\_IP\_ADDRESS = “10.42.0.1”  
MENDER\_SERVER\_URL = “[https://mender.solid.com](https://mender.solid.com)”

You do not need this if you have production server, nor do you need to update the /etc/hosts" file.

> MENDER\_SERVER\_URL = “[https://mender.solid.com](https://mender.solid.com/)”

Above is all you need + your custom `server.crt` if you generated as such.

Please use the `sign` command instead of `modify`, e.g

```
 mender-artifact sign artifact.mender -k private.key -o artifact-signed.mender

```

We are aware of some problems with `modify` and that is what you are seeing here.

I am able to sign the artifact and upgrade to new releases…

I need to use the mender-artifact to write the ip address and server name in to /etc/hosts file for mender client to access the server… I created the certificate for Gateway\_API as well for my production server…  
So MENDER\_SERVER\_URL = “[https://mender.solid.com](https://mender.solid.com)” in local.conf not working for me… Usually mender client trying access “[https://mender.solid.com](https://mender.solid.com)” on localhost only
