### Setup Vagrant


Change to client / project folder

```
vagrant box add ubuntu/trusty64
```

Now initialize the new vagrant in your VirtualMachines/ubuntu directory with the init command.

```
vagrant init ubuntu/trusty64
```

Finally, get Ubuntu up and running with the vagrant up command.

```
vagrant up
```

Fixing Guest Additions Error

```
vagrant halt
```

Let’s quickly install a plugin called vbguest to fix this error.

```
vagrant plugin install vagrant-vbguest
```

Let’s reload the Vagrant machine with the reload command.

```
vagrant reload
```

SSH into ubuntu

```
vagrant ssh
```

You’re in! You now have a complete Ubuntu Server installation running through VirtualBox on your computer, and you’re connected to it. Type exit at any time to exit out of the server, and vagrant halt to shut it down.


### Apache

apt-get is command line software for installing packages on Ubuntu. Let’s run the commands to update and upgrade the package manager and make sure everything is up to date.

```
sudo apt-get update && sudo apt-get upgrade
```

```
sudo apt-get install apache2 -y
```

Fix Warning: AH00558: apache2: Could not reliably determine the server's 
fully qualified domain name, using 10.0.2.15. Set the 'ServerName' 
directive globally to suppress this message

```
sudo nano /etc/apache2/apache2.conf
```

At the end of the file add

```
ServerName localhost
```

Restart apache

```
sudo service apache2 restart
```

Test apache config

```
sudo apache2ctl configtest
```

Now, usually when you set up a production server, you can navigate to the IP address or domain name of the server in your browser and see either the “New Linux installation” page, or your website, if you’ve already added it. We’re going to do the same thing right now, except instead of connecting to a public facing server, we’re connecting to our own local virtual machine.

Within the client / project directory, you’ll see two files – .vagrant, and Vagrantfile. Open your Vagrantfile, as this is the local configuration file we’ll need to edit to make any changes.

Uncomment

```
config.vm.network "private_network", ip: "192.168.33.10"
```

Reload Vagrant in the local terminal

```
vagrant reload
```

We’re going to make a custom domain to access this address and view it in our browser. Still in your local computer, edit your local hosts file.

```
sudo nano /etc/hosts
```

```
192.168.33.10  trusty.loc
```

Save and exit nano. Now in Google Chrome or whatever browser you’re using, go to trusty.dev. Now you should see the default Linux success page. It works!


### PHP

log back into the box

```
vagrant ssh
```

Add the Onrej PPA to your machine.

```
sudo apt-add-repository ppa:ondrej/php
```

update

```
sudo apt-get update
```

install php 7.1

```
sudo apt-get install php7.1
```

Confirm php

```
php -v
```

### Link a local folder with the virtual machine

Right now, the Ubuntu default page exists on /var/www/html

Back in our local (Windows or Mac) computer, let’s create a public_html folder in the root directory, and create two files: connect.php and test.php, which we’ll use to test MySQL and PHP in a moment.

Let’s go back to our Vagrantfile. We’re going to set up a synced folder, first inputting our local path, then inputting our virtual machine’s path.

```
#config.vm.synced_folder "LOCAL", "VIRTUAL"
config.vm.synced_folder "public_html", "/var/www/html"
```

Now vagrant reload, or vagrant halt and vagrant up to restart Ubuntu. Now when you go to your server you should see this.


### Mysql

```
sudo apt-get install mysql-server php7.1-mysql
```

```
sudo mysql_secure_installation
```

Enter Password i.e.

```
root
```

```
sudo nano /etc/mysql/my.cnf
```

Connect to mysql via ssh

```
http://prntscr.com/hyrg4o
```

Restart apache

```
sudo service apache2 restart
```

Restart Mysql

```
sudo service mysql restart
```

Login to test mysql

```
mysql -u root -p
```

grant on mysql

```
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
```

### Testing PHP and MySQL

in test.php

```
<?php phpinfo();
```

in connect.php

```
<?php

$dbname = 'test';
$dbuser = 'root';
$dbpass = 'root';
$dbhost = '127.0.0.1';

$link = mysqli_connect($dbhost, $dbuser, $dbpass) or die("Unable to Connect to '$dbhost'");
mysqli_select_db($link, $dbname) or die("Could not open the db '$dbname'");

$test_query = "SHOW TABLES FROM $dbname";
$result = mysqli_query($link, $test_query);
$tblCnt = 0;

while($tbl = mysqli_fetch_array($result)) {
  $tblCnt++;
}

if (!$tblCnt) {
  echo "There are no tables<br />\n";
} else {
  echo "There are $tblCnt tables<br />\n";
}

```
