Magento 2.3.4 installation issues

Question

I am trying to install magento 2.3.4 on a LAMP stack on centos. Php version 7.3 and mysql 5.6. Initially setup was giving a 500 error. I searched google and found a suggestion to remove .htaccess. it worked. Now it gives 404 error for admin page after installation and homepage appears without any css and media. If I put the .htaccess back to root folder of magento, it gives 500 error for both admin and magento store. Can you please help me find the problem.
