Exercise - Install software on your VM - Training

5 minutes

The last thing we want to try on our VM is to install a web server. One of the easiest packages to install is nginx.

Install NGINX web server

Locate the public IP address of your SampleVM Linux virtual machine.
```
az vm list-ip-addresses --name SampleVM --output table
```
Next, open an ssh connection to SampleVM using the Public IP address from the preceding step.
```
ssh azureuser@<PublicIPAddress>
```
After you're logged in to the virtual machine, run the following command to install the nginx web server. The command will take a few moments to complete.
```
sudo apt-get -y update && sudo apt-get -y install nginx
```
Exit the Secure Shell:
```
exit
```

Retrieve your default page

In Azure Cloud Shell, use curl to read the default page from your Linux web server by running the following command, replacing <PublicIPAddress> with the public IP you found previously. You can also open a new browser tab and try to browse to the public IP address.
```
curl -m 80 <PublicIPAddress>
```
This command will fail, because the Linux virtual machine doesn't expose port 80 (http) through the network security group that secures the network connectivity to the virtual machine. We can fix the failure by running the Azure CLI command vm open-port.
Enter the following command into Cloud Shell to open port 80:
```
az vm open-port \
    --port 80 \
    --resource-group <rgn>[sandbox resource group name]</rgn> \
    --name SampleVM
```
It will take a moment to add the network rule and open the port through the firewall.

Run the curl command again.

curl -m 80 <PublicIPAddress>

This time, it should return data like the following. You can see the page in a browser as well.

<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {
    width: 35em;
    margin: 0 auto;

</style>
</head>
<body>

working. Further configuration is required.</p>
