How to Install Apache on CentOS 7


How to Install Apache on CentOS 7

Apache HTTP worker is the most famous web worker on the planet. It is a free, open-source and cross-stage HTTP worker giving ground-breaking highlights which can be stretched out by a wide assortment of modules. The accompanying directions depict how to introduce and deal with the Apache web worker on your CentOS 7 machine. 


Prior to beginning with the instructional exercise, ensure you are signed in as a client with sudo advantages . 

Installing Apache

Apache is accessible in the default CentOS stores and the establishment is really straight forward. 

On CentOS and RHEL the Apache bundle and the administration is called httpd. To introduce the bundle run the accompanying order: 

sudo yum install httpd

When the establishment is finished, empower and start the Apache administration: 

sudo systemctl enable httpd
sudo systemctl start httpd

Adjusting the Firewall

In the event that your worker is ensured by a firewall you need to open HTTP and HTTPS ports, 80 and 443. Utilize the accompanying orders to open the vital ports: 

sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload

Verifying Apache Installation

Since we have Apache introduced and running on our CentOS 7 worker we can check the status and the variant of the Apache administration, with: 

sudo systemctl status httpd
? httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2018-04-26 07:13:07 UTC; 11s ago
     Docs: man:httpd(8)
 Main PID: 3049 (httpd)
sudo httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Oct 19 2017 20:39:16

At long last to check if everything works appropriately, open your worker IP address http://YOUR_IP in your program of decision, and you will see the default CentOS 7 Apache invite page as demonstrated as follows: 

Managing Apache Service

You can deal with the Apache administration similarly as some other systemd unit. 

To stop the Apache administration, run: 

sudo systemctl stop httpd

To begin it once more, type: 

sudo systemctl start httpd

To restart the Apache administration: 

sudo systemctl restart httpd

To reload the Apache administration after you made some setup changes: 

sudo systemctl reload httpd

In the event that you need to debilitate the Apache administration to begin at boot: 

sudo systemctl disable httpd

Also, to re-empower it once more: 

sudo systemctl enable httpd

Apache Configuration File’s Structure and Best Practices

  • All Apache arrangement documents are situated in the/and so on/httpd registry. 
  • The principle Apache arrangement document is/and so on/httpd/conf/httpd.conf. 
  • All config documents finishing with .conf situated in the/and so on/httpd/conf.d registry are remembered for principle Apache arrangement record. 
  • Design documents which are answerable for stacking different Apache modules are situated in the/and so on/httpd/conf.modules.d index. 
  • For better viability it is prescribed to make a different arrangement document (vhost) for every space. 
  • New Apache vhost documents should end with .conf and be put away in/and so on/httpd/conf.d index. You can have the same number of vhosts as you need. 
  • It is a smart thought to keep a standard naming show, for instance on the off chance that your space name is, at that point you the setup document should be named/and so forth/httpd/conf.d/ 
  • Apache log documents (access_log and error_log) are situated in the/var/log/httpd/index. It is prescribed to have an alternate access and blunder log documents for each vhost. 
  • You can set your space report root index to any area you need. The most well-known areas for webroot include: 
    • /home/<user_name>/<site_name> 
    • /var/www/<site_name> 
    • /var/www/html/<site_name> 
    • /pick/<site_name> 


You have effectively introduced Apache on your CentOS 7 worker. You're presently prepared to begin sending your applications and use Apache as a web or intermediary worker. 

In the event that you have any inquiries or criticism, don't hesitate to leave a remark.
