=== What is Apache? ⌘===
* Mature, stable HTTP server
* Many, many features
* Many, many modules available
=== Installing ⌘===
* Included in the standard EL5 repos
* `yum -y install httpd`
=== Changing the configuration ⌘===
* Main configuration file at `/etc/httpd/conf/httpd.conf`
* Syntax check with `service httpd configtest`
* Re-read config with `service httpd reload`
* Some actions (eg adding SSL certs) require a full restart
`service httpd restart`
=== Virtualhosts ⌘===
* Create a file /etc/httpd/conf.d/vhost.conf
```
<VirtualHost *:80>
ServerName localhost
DocumentRoot /var/www/html
CustomLog /var/log/httpd/localhost-access.log combined
ErrorLog /var/log/httpd/localhost-error.log
</VirtualHost>
```

=== Adding altername names to a vhost ⌘===
* Alternate names can be added via the ServerAlias parameter
* Multiple names can be specified, separated by a space
=== Default VirtualHost ⌘===
* The default virtualhost is the one that is the first alphabetically
* This will be used even if the ServerName/ServerAlias doesn't match if you remove welcome.conf
=== IP based virtual hosts ⌘===
* What we just created was a name based VirtualHost
* We can also create address based VirtualHosts
* These are commonly used with SSL
```
NameVirtualHost 192.168.34.1:80
<VirtualHost 192.168.34.1:80>
DocumentRoot /var/www/html
CustomLog /var/log/httpd/localhost-access.log combined
ErrorLog /var/log/httpd/localhost-error.log
</VirtualHost>
```
=== Exercise ⌘===
* There is some content under /var/www/exercise
* Create a virtualhost which will serve this only in response to a request for localhost.localdomain
:* `$ curl http://localhost.localdomain/`
