Probably, you need something like this:

server {

    ...

    fastcgi_ignore_client_abort off;
    fastcgi_intercept_errors off;
    fastcgi_read_timeout 10;

    index   index.php;

    location /wiki/ {
        alias /usr/local/www/site_wiki/;
    }

    location ~ ^/wiki/.+\.php$ {
        alias /usr/local/www/site_wiki/;
        try_files $uri /404.html;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME   $request_filename;
        include /usr/local/etc/nginx/fastcgi_params;
    }

    location / {
        root  /usr/local/www/site_main/;
    }

    location ~ \.php$ {
        root  /usr/local/www/site_main/;
        try_files $uri /404.html;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME   $request_filename;
        include /usr/local/etc/nginx/fastcgi_params;
    }

BTW, "worker_connections 64" are too small for 2 workers. This means
that server is able to serve just 128 connections. This is not enough
in modern world.
