# Installing Apache2

Apache is a cross-platform software that supports Linux, BSD, Mac OS, Microsoft Windows, Novell NetWare, and BeOS operating systems.

## Installation Apache2:

To install **Apache2** on **VDS**, you must register:

```
apt-get install apache2
```

## Customization Apache2:

To configure **Apache2**, go to /etc/apache2/sites-available and create a file modeled on site.conf:

```
<VirtualHost *:80>
        ServerName spacecore.pro # Specify the site domain
        ServerAdmin admin@spacecore.pro # Your email address
        DocumentRoot /var/www/html # The path to the site folder

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
```

Turning on the site, the site.conf location should be the name of the config that you created:

```
a2ensite site.conf
```

If you need to **disable the site**, the name of the config should be instead of site.conf:

```
a2dissite site.conf
```

Rebooting **apache2**:

```
service apache2 reload
```

### Connecting PHP to Apache2:

In order for **Apache** to display **php** files correctly, you need to install the package:

```
apt-get install libapache2-mod-php -y
```

Rebooting **apache2**:

```
service apache2 reload
```

### Enabling rewrite:

{% hint style="danger" %}
Without this option, 70% of CMS for websites will not work.
{% endhint %}

Most sites contain a file.**htaccess** must be registered for its operation:

```
a2enmod rewrite
```

Rebooting **apache2**:

```
service apache2 reload
```

### Enabling SSL:

{% hint style="info" %}
**SSL** connection is not required, it is carried out if it is available and you wish.
{% endhint %}

You need to enable the module that is responsible for **SSL**:

```
a2enmod ssl
```

Creating another config in /etc/apache2/sites-available, it will be responsible for **SSL**, for example site-ssl.conf:

{% code title="site-ssl.conf" %}

```
<VirtualHost *:443>
        ServerName spacecore.pro # Specify the site domain
        ServerAdmin admin@spacecore.pro # Your email address
        DocumentRoot /var/www/html # The path to the site folder
        
        SSLEngine on
        SSLCertificateFile /path/to/your_domain_name.pem # The path to the public certificate
        SSLCertificateKeyFile /path/to/your_private.key # The path to the private certificate

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
```

{% endcode %}

Rebooting **apache2**:

```
service apache2 reload
```

## Check на nginx:

If **apache2** is installed with nginx, then they will conflict due to port - 80. So you need to delete one of the **web servers**. Check if nginx is installed:

```
service nginx status
```

{% hint style="info" %}
If a huge message with information is not visible, then it is not installed.
{% endhint %}

If **nginx** is installed, you need to delete it:

```
apt-get remove --purge nginx* -y
```

## Removal Apache2

To remove **Apache2**, use:

```
apt-get remove --purge apache2* -y
```
