Wordpress permalink not working on aws

I have spent 4-5 hours to sort it out but not able to solve it.

I have setup my wordpress website on AWS.Everything is working file except the permalinks of wordpress.

When permalinks are set to default pages/posts are working but not working with "%post-name%".

I have tried almost all the things by searching over google but no success.

I saw so many solutions all related to httpd.conf file but on my root there is no file httpd.conf neither no directory of http.

I changed the following code in apache.conf file but still not working

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Require all denied
</Directory>

<Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

Restarted apache again and again but no luck.

Please help me guys.

Thanks.
