how to create virtual host in redhat OS with AWS ENV?

I am new in AWS.I am using following env.

OS: Redhat AWS: FREE ACCOUNT Webserver: Apache Database: Mysql

I have created a file for virtual host:

File name: projectname.conf

<VirtualHost *:80>
        DocumentRoot /var/www/vhosts/projectname/stacks/public       
        ErrorLog /var/www/logs/projectname-default-error.log
        CustomLog /var/www/logs/projectname-default-access.log common
        RewriteEngine ON   

        ScriptAlias /cgi-bin-projectname/ /var/www/vhosts/projectname/conf/

        <Directory "/var/www/logs/">
                Options FollowSymlinks -Indexes
                AllowOverride All
        </Directory>

        <Directory "/var/www/vhosts/projectname/">
                AllowOverride None
                Options None
                Order allow,deny
                Allow from all
        </Directory>

       DirectoryIndex  index.php index.html

</VirtualHost>

update httpd.conf file as well

at bottom

NameVirtualHost *:80
Include vhosts/*.conf

try to apache restart

[root@ip-1xx-xx-xx-xxx /]#  service httpd restart
Redirecting to /bin/systemctl restart  httpd.service
Job for httpd.service failed. See 'systemctl status httpd.service' and 'journalctl -xn' for details.
