If you have an ESX instance that is not connected to VSphere then you do not get a web interface and using the client is a pain, you can add the UI to the ESX server using these commands below:
- Download the VIB file
- SSH into your ESXi host
- Copy the VIB file to /tmp/ (I used WInSCP)
Then run the command, I have copied it to the /tmp folder but you may have used a different folder:
esxcli software vib install -v /tmp/esxui_signed.vib
That will then install the client and then you can visit the website using the URL:
https://<device_name>/UI
That should look like this, and you login with the root password you setup during install.....
Then when you login it will look like this:
