ng build --prod --base-href=/petclinic/ --deploy-url=/petclinic/

2. Create sub-directory /petclinic in default Apache directory /var/www/html

3. Go into Angular appication /dist sub-directory and copy all files and sub-dirs from it to /var/www/html/petclinic

4. Edit Apache config (/etc/https/conf/httpd.conf):

sudo vi /etc/httpd/conf/httpd.conf

Find the Directory /var/www/html> section and change the AllowOverride directive from None to All:

 /etc/httpd/conf/httpd.conf
 . . .
  <Directory /var/www/html>

 # AllowOverride controls what directives may be placed in .htaccess files.
 # It can be "All", "None", or any combination of the keywords:
 # Options FileInfo AuthConfig Limit
 #
 AllowOverride All

sudo vi /var/www/html/petclinic/.htaccess

Add the following line to the top of the file to activate the RewriteEngine, which instructs Apache to process any rules that follow:

RewriteEngine On  
# If an existing asset or directory is requested go to it as it is
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]  
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d  
RewriteRule ^ - [L]

# If the requested resource doesn't exist, use index.html
RewriteRule ^ index.html  

7. Reload Apache:

sudo systemctl restart httpd

8. Run app in browser: http://server_name/petclinic/
