A simple configuration example of a Web site in CentOS6:

~]# Yum install-y httpd httpd-manual httpd-tools//Required documentation files for installing HTTPD applications

2. Ensure that the SELinux and iptables firewalls do not interfere with the provision of httpd services:
SELinux configuration:
~]# Getenforce//view selinux status
Enforcing
~]# Setenforce 0//Set SELinux to

Firewall:
~]# IPTABLES-VNL//view host for firewall status
If there is a firewall rule in its execution result

, the following processing is required:
~]# service iptables stop//stops firewall services, limited to lab environment shutdown
~]# chkconfig iptables off//Set Firewall service on start-up shutdown
~]# iptables-f

3. Add an HTML document:/var/www/html/index.html

4. Start the HTTPD service
~]# Service httpd Start

5. Monitoring service startup is normal:
~]# SS-TNL | grep httpd//Listener port number, check whether the httpd service is turned on, the general default is 80
~]# PS aux | grep httpd//See if the process has httpd process enabled
~]# Service httpd Status//view state of HTTPD services
