1. Устанавливаете 2 версии php
2. Выкидываете апач, ставите и настраиваете nginx-конфиг для каждого домена/порта нужным образом
Пример моего тестового конфига:
server {
listen 80;
server_name test.loc;
root /var/www/test.loc;
index index.php index.html index.html;
access_log /var/log/nginx/test.loc.log;
error_log /var/log/nginx/test.loc.error;
gzip on;
gzip_vary on;
gzip_min_length 1000;
gzip_proxied expired no-cache no-store private auth;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript image/svg+xml;
