15.2 Installing the Apache HTTP Server

To install the Apache HTTP server:

Enter the following command:
```
# yum install httpd
```
Start the server, and configure it to start after system reboots:
```
# service httpd start
# chkconfig httpd on
```
Check for configuration errors:
```
# service httpd configtest
```
Create firewall rules to allow access to the ports on which the HTTP server listens, for example:
```
# iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
# service iptables save
```
