Answer 1

The location and alias should both have a trailing / or neither have a trailing /. But in your case, you should be using root instead of alias for both location blocks.

location /roundcube {
    root /var/www;
    index index.php;

    location ~ \.php$ {
        try_files $uri =404;

        fastcgi_pass unix:/var/run/php5-fpm.sock;

        include /etc/nginx/fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

location /phpmyadmin {
    root  /usr/share;
    index  index.php index.html index.htm;

    location ~ \.php$ {
        try_files $uri =404;

        fastcgi_pass unix:/var/run/php5-fpm.sock;

        include /etc/nginx/fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

The fastcgi_index will not do anything in a location that only matches .php (see this document).

The SCRIPT_FILENAME parameter is needed in both blocks (or neither if it is already in /etc/nginx/fastcgi_params).
