fastcgi

fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/path/to/php-fpm.sock;

fastcgi_param

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;    一般只需要这个
include fastcgi_params;                                   其他的参数都写在这个文件中了

fastcgi_pass_header X-Forwarded-For   显示 header
fastcgi_hide_header X-Forwarded-For   隐藏 header

fastcgi_index index.php;

fastcgi_split_path_info
如果访问: http://localhost/index.php/Home/Index/index.html

location ~ \.php {
    fastcgi_split_path_info ^(.*\.php)(.*)$;
    # 经过上面的配置之后, $fastcgi_script_name 就会变成 /index.php, $fastcgi_path_info 就会变成 /Home/Index/index.html
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PATH_INFO $fastcgi_path_info;
}

另一种配置 path_info 方式

location ~ (.*\.php)(.*)$ {
    fastcgi_param SCRIPT_FILENAME $document_root$1;
    fastcgi_param PATH_INFO $2;
}

buffer

fastcgi_buffers 8 4k;            8 个 buffer, 每个 4k
fastcgi_buffer_size 4k;          默认和上面的一样

fastcgi_next_upstream    error | timeout | invalid_header | off
