Apache is a free, open source and popular HTTP Server that runs on Unix-like operating systems including Linux and also Windows OS. Since its release 20 years ago, it has been the most popular web server powering several sites on the Internet. It is easy to install and configure to host single or multiple websites on a same Linux or Windows server.
In this article, we will explain how to install, configure and manage Apache HTTP web server on a CentOS 7 or RHEL 7 server using command line.
- A CentOS 7 Server Minimal Install
- A RHEL 7 Server Minimal Install
- A CentOS/RHEL 7 system with static IP address
Install Apache Web Server
1. First update the system software packages to the latest version.
# yum -y update
2. Next, install Apache HTTP server from the default software repositories using the YUM package manager as follows.
# yum install httpd
Manage Apache HTTP Server on CentOS 7
3. Once Apache web server installed, you can start it first time and enable it to start automatically at system boot.
# systemctl start httpd # systemctl enable httpd # systemctl status httpd
Configure firewalld to Allow Apache Traffic
4. By default, CentOS 7 built-in firewall is set to block Apache traffic. To allow web traffic on Apache, update the system firewall rules to permit inbound packets on HTTP and HTTPS using the commands below.
# firewall-cmd --zone=public --permanent --add-service=http # firewall-cmd --zone=public --permanent --add-service=https # firewall-cmd --reload
Test Apache HTTP Server on CentOS 7
5. Now you can verify Apache server by going to the following URL, a default Apache page will be shown.
Configure Name-based Virtual Hosts on CentOS 7
This section only useful, if you want to host more than one domain (virtual host) on the same Apache web server. There are many ways to setup a virtual host, but we will explain one of the simplest methods here.
6. First create a
vhost.conf file under
/etc/httpd/conf.d/ directory to store multiple virtual host configurations.
# vi /etc/httpd/conf.d/vhost.conf
Add the following example virtual host directive template for website
mytecmint.com, make sure to change the necessary values for your own domain
NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin [email protected] ServerName mytecmint.com ServerAlias www.mytecmint.com DocumentRoot /var/www/html/mytecmint.com/ ErrorLog /var/log/httpd/mytecmint.com/error.log CustomLog /var/log/httpd/mytecmint.com/access.log combined </VirtualHost>
Important: You can add as many as domains to vhost.conf file, just copy the
VirtualHost block above and change the values for each domain you add.
7. Now create the directories for
mytecmint.com website as referenced in the
VirtualHost block above.
# mkdir -p /var/www/html/mytecmint.com [Document Root - Add Files] # mkdir -p /var/log/httpd/mytecmint.com [Log Directory]
8. Create a dummy index.html page under /var/www/html/mytecmint.com.
# echo "Welcome to My TecMint Website" > /var/www/html/mytecmint.com/index.html
9. Finally, restart Apache service for the above changes to take effect.
# systemctl restart httpd.service
10. Now you can visit
mytecmint.com to test the index page created above.

I am using CentOS 7 inside VMWare.
Apache works when I just put in the IP i.e 192.168.0.141
I want that from my windows machine on which VMWare I have installed, the result of Apache should reflect when I put the IP on the browser.
What additional thing do I need to do for that?
Just open the port 80 on the system to access the Apache from your internal network.
Try to enable host-only networking or network bridge between the VMWare and Windows host, like in VirtualBox.
How to set an automatic logout on Apache HTTP Server
I have configured a balancer-manager in apache with the login page so that the user has to log in to see the balancer-manager page. But once I log in to balancer-manager page using AuthName it stays logged in for an infinite time.
Is it possible to set a time out or expiry timer for the currently logged in session after in case of no activity so that the user has to login again to see /balancer-manager page?
balancer-manager configuration in httpd.conf are as below:
If anyone can help me with an answer that will be great!
@bread of Wakanda
You can enable a session-based configuration, read the balancer-manager module documentation for more information: https://httpd.apache.org/docs/2.4/mod/mod_proxy_balancer.html.
If that does not help, try enabling basic HTTP authentication: https://www.tecmint.com/password-protect-apache-web-directories-using-htaccess/.
Sir, I have done exactly what you said in the tutorial, and i got the output also, but when i search using ip/localhost the website appear but when i enter the name of the site ( i created tecmint.com) the page is not displaying and shows error.
You need to add tecmint.com with your server IP address on your local machine hosts file from where you accessing the site.
Let me check and tell you. if possible pleas share your mail id or anything to contact you personally.
