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/`
