Step2# Congiure httpd configuration file named httpd.conf
Before edit httpd.config file, you’d better have a backup for this file, type:
cp httpd.conf httpd.conf.bak
Edit “/etc/httpd/conf/httpd.conf” file using “vim” command, type:
vim /etc/httpd/conf/httpd.conf
set new values for “ServerAdmin“, ” ServerName“, “AllowOverride” , “DirectoryIndex” and “keepAlive” fields just like the below:
ServerAdmin itsprite@gmail.com # set its value as admin's email address ServerName www.itsprite.com :80 # set its value as your web server's domain name AllowOverride all # set its as "all" DirectoryIndex index.html index.php # add file name if your www directory have index.php file. DocumentRoot "/var/www/html" #By default, all requests are taken from this directory
Step3# Enable httpd service while system startup
issue the following command to start httpd server automatically while system booting up, type:
systemctl enable httpd.service
Outputs:
[root@osetc Desktop]# systemctl enable httpd.service ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
Step4# Start Apache httpd service, issue the following command:
systemctl start httpd.service
Outputs:
[root@osetc Desktop]# systemctl status httpd.service httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled) Active: active (running) since Thu 2014-12-04 10:13:36 EST; 7s ago Main PID: 12630 (httpd) Status: "Processing requests..."

Step5# Create a HTML test page under DocumentRoot directory (the default is “/var/www/html”), type:
$sudo echo "this is a test page" >/var/www/html/index.html
Step6# Verifying the test page can be resolved by Apache HTTP Server
Open firefox brower, and input address “127.0.0.1”, if you can see the below similar page, indicated that your Apache web server was setup successfully.
