## Apache
|
|
|
|
The Apache HTTP Server, commonly known as Apache, is a free and open-source cross-platform web server, released under the terms of [Apache License 2.0](https://en.wikipedia.org/wiki/Apache_License). Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation.
|
|
Apache runs on 67% of all webservers in the world. It is fast, reliable, and secure. It can be highly customized to meet the needs of many different environments by using extensions and modules

### Installation
|
|
|
|
#### On Ubuntu/Debian
|
|
```
|
|
sudo aptitude install apache2
|
|

|
### Getting Started
|
|
Once you have Apache installed you need to know where to put your HTML documents. This location is generally referred to as the `DocumentRoot`. This location is usually `/var/www/html` on most Linux systems. Follow the instructions below to find the configuration file for Apache and the `DocumentRoot`.
|
|
|
|
#### Command
|
|
```
|
|
~$ sudo grep "DocumentRoot" -R /etc/
|
|
```
|
|
|
|
The `-R` flag will cause grep to search recursively through the `/etc` directory and print out the full path of the file that it finds the `DocumentRoot` keyword in.
|
|
|
|
#### Ubuntu output
|
|
```
|
|
/etc/apache2/sites-available/000-default.conf: DocumentRoot /var/www/html
|
|
/etc/apache2/sites-available/default-ssl.conf: DocumentRoot /var/www/html
|
|
/etc/apache2/sites-enabled/000-default.conf: DocumentRoot /var/www/html
|
|
```
|
|
|
|
#### Centos output
|
|
```
|
|
/etc/httpd/conf/httpd.conf DocumentRoot /var/www/html
|
|
```
