How to Install Apache on CentOS 7

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.


  1. A CentOS 7 Server Minimal Install
  2. A RHEL 7 Server Minimal Install
  3. A CentOS/RHEL 7 system with static IP address

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

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, make sure to change the necessary values for your own domain

NameVirtualHost *:80

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/html/
    ErrorLog /var/log/httpd/
    CustomLog /var/log/httpd/ combined
Apache Virtual Host Configurations
Apache Virtual Host Configurations

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 website as referenced in the VirtualHost block above.

# mkdir -p /var/www/html/    [Document Root - Add Files]
# mkdir -p /var/log/httpd/   [Log Directory]

8. Create a dummy index.html page under /var/www/html/

# echo "Welcome to My TecMint Website" > /var/www/html/

9. Finally, restart Apache service for the above changes to take effect.

# systemctl restart httpd.service

10. Now you can visit to test the index page created above.

  1. Hi All,

    I am using CentOS 7 inside VMWare.

    Apache works when I just put in the IP i.e

    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?

    Thank you,
    Kunder Akshay,

  2. How to set an automatic logout on Apache HTTP Server /balancer-manager page?

    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:

            SetHandler balancer-manager
            AuthType basic
            AuthName "wakanda"
            AuthUserFile "/etc/httpd/passwd/passwords"
            Require valid-user
        ProxyPass /balancer-manager ! 

    If anyone can help me with an answer that will be great!

  3. 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 the page is not displaying and shows error.

    • @Srju,

      You need to add with your server IP address on your local machine hosts file from where you accessing the site.

      • Thank you,

        Let me check and tell you. if possible pleas share your mail id or anything to contact you personally.

  4. My Apache doesn’t run if i do not configure /etc/hosts file. So is it necessary to configure hosts file in etc directory?

  5. Hello Sir i am new to Linux and I followed all your instructions but when i try to restart it this is what i get

    [root@pdg ~]# systemctl restart httpd.service
    Job for httpd.service failed because the control process exited with error code. 
    See "systemctl status httpd.service" and "journalctl -xe" for details.

    Please your help need this to work out for me thanks.

    • @John

      Please, carefully read the output of the command:

      # systemctl restart httpd.service
      # journalctl -xe

      It shows that your configuration has an error.

  6. Hello Sir,

    I have done exactly what you did but the httpd refused to restart please see below.

    Please what can i do?

  7. Hello Sir, I already did what you done, and the httpd.service is active (running) but when i type the IP address on my browser, i received a 504 Gateway timeout. What should i do??

    • @Luke,

      I think it’s due to proxy server settings, try to disable proxy in your browser and try.. If you still see same error, try to check the Apache logs at /var/log/httpd and fix the issue if any..

  8. Hello, Dear Sir

    My Apache web server stopped some how. I run service httpd restart on terminal, but it not worked.

    It show:

    [root@localhost ~]# service httpd restart

    httpd: Syntax error on line 216 of /usr/local/apps/apache/etc/httpd.conf: Syntax error on line 2 of /usr/local/apps/apache/etc/conf.d/wsgi.conf: Cannot load /us r/local/apps/apache/modules/ into server: /usr/local/apps/apache/modu les/ cannot open shared object file: No such file or directory

    Kindly tell me How To fix it.

    • @Rajib

      Run the command below:

      # mv /usr/local/apps/apache/etc/conf.d/wsgi.conf /usr/local/apps/apache/etc/conf.d/wsgi.conf.orig

      Then restart the Apache service, like this:

      # service httpd restart

      If this fails, try to check the mentioned files for any syntax errors on the specified lines.
