Now install Apache server running below command.
sudo yum install httpd
If you have installed firewalld in your server, then you need to open port 80 to allow apache to handle the requests. You can do it by running the below command.
sudo firewall-cmd --permanent --add-service=http
Or if you have installed SSL certificate for the domain, you need to open port 443.
sudo firewall-cmd --permanent --add-service=https
Now reload firewall services.
sudo firewall-cmd --reload
You need to start apache server in CentOS server.

If you want to stop apache server, you can stop the apache server with below command.
sudo systemctl stop httpd
To restart the the server, run this command:
sudo systemctl restart httpd
If you want to check apache status, you can run the command:

Configure Apache server
Apahe main configuration file located at /etc/httpd/conf/httpd.conf. The default directory apache handle is /var/www/html. So if you want to put the website project at different directory or want to add multiple domains, you need to creat seperate configuration file for each domain.
First add the domain configuration file path in the main apache configuration file. Open /etc/httpd/conf/httpd.conf file in nano editor.
sudo nano /etc/httpd/conf/httpd.conf
And add the filepath at the end of file in it.
IncludeOptional sites-enabled/*.conf
Save and exit the file. Now create a file with your domain name and put the configuration options with appropriate file path.
sudo nano /etc/httpd/sites-enabled/domain.com.conf
<VirtualHost *:80>
ServerName www.domain.com
ServerAlias domain.com
DocumentRoot /var/www/html/domain.com
ErrorLog /var/www/html/domain.com/log/error.log
CustomLog /var/www/html/domain.com/log/requests.log combined
</VirtualHost>
Save and exit the file. That's it. Your domain is successfully configured to served at the path /var/www/html/domain.com directory.
