    apt-add-repository ppa:ondrej/apache2
    
    apt-get -y update
    
  2. Install Apache 2.4:

Installing Apache on CentOS

Adobe Commerce requires Apache server rewrites. You must also specify the type of directives that can be used in .htaccess, which the application uses to specify rewrite rules.

Installing and configuring Apache is basically a three-step process: install the software, enable rewrites, and specify .htaccess directives.

Installing Apache

  1. Install Apache 2.4 if you have not already done so.

    yum -y install httpd
    
  2. Verify the installation:

    httpd -v
    

    Messages similar to the following display to confirm that the installation was successful:

    Server version: Apache/2.4.40 (Unix)
    Server built: Oct 16 2020 14:48:21
    
  3. Continue with the next section.

    NOTE
    Even if Apache 2.4 is provided by default with CentOS, see the following section to configure it.

Enable rewrites and .htaccess for CentOS

  1. Open /etc/httpd/conf/httpd.conf file for editing:

    vim /etc/httpd/conf/httpd.conf`
    
  2. Locate the block that starts with:

    <Directory "/var/www/html">
    
  3. Change the value of AllowOverride to All.

    For example,

    <Directory "/var/www/">
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Order allow,deny
      Allow from all
    </Directory>
    
    NOTE
    The preceding values for Order might not work in all cases. For more information, see the Apache documentation (2.4).
  4. Save the file and exit the text editor.

  5. To apply Apache settings, restart Apache.

    service apache2 restart
    
NOTE
Failure to enable these settings typically results in no styles displaying on your storefront or Admin.

Enable rewrites and .htaccess for Ubuntu

  1. Open /etc/apache2/sites-available/default file for editing:

    vim /etc/apache2/sites-available/default
    
  2. Locate the block that starts with:

    <Directory "/var/www/html">

  3. Change the value of AllowOverride to All.

    For example:

    <Directory "/var/www/html">
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Order allow,deny
      Allow from all
    </Directory>
    
  4. Save the file and exit the text editor.

  5. Configure Apache to use the mod_rewrite module:

    cd /etc/apache2/mods-enabled
    
    ln -s ../mods-available/rewrite.load
    
  6. Restart Apache to apply changes:

    service apache2 restart
