This value is commented out.
$ grep cgi.fix_pathinfo php.ini
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for
CGI.  PHP's
;cgi.fix_pathinfo=1
I've never edited php.ini.

Great!! Both of CGI and PHP finally works!!
I made configuration file by copying from configuration file which I found
from somewhere and I did not understand what fastcgi_param means.
Thanks so much for your help!

I put successful configuration here again for future use.

/etc/nginx/conf.d/default.conf
server {
    listen       80;
    server_name  localhost;
    access_log  /var/log/nginx/access.log;
    error_log   /var/log/nginx/error.log debug;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {
        root   /var/www/html;
        index  index.html index.htm;
    }

    location ~ ^/~(.+?)(/.*)?\.(php)$ {
        alias /home/$1/public_html$2.$3;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root;
        include        /etc/nginx/fastcgi_params;
    }

    location ~ ^/~(.+?)(/.*)?\.(pl|cgi)$ {
        alias /home/$1/public_html$2.$3;
        fastcgi_pass   127.0.0.1:8999;
        fastcgi_index  index.cgi;
        fastcgi_param  SCRIPT_FILENAME $document_root;
        include        /etc/nginx/fastcgi_params;
    }

    location ~ ^/~(.+?)(/.*)?$ {
        alias /home/$1/public_html$2;
        index  index.html index.htm;
        autoindex on;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;

    location ~ \.php$ {
        root           /var/www/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        /etc/nginx/fastcgi_params;
    }
    location ~ \.pl|cgi$ {
        root           /var/www/html;
        fastcgi_pass   127.0.0.1:8999;
        fastcgi_index  index.cgi;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
