nginx502错误 connect() to unix:/tmp/php-cgi.sock failed (2: No such file or directory)

访问html,txt文件正常，但是访问php文件报502；

nginx日志报错

 其中，我的是enable-php.conf文件

      location ~ [^/].php(/|$)
        {
            try_files $uri =404;
            fastcgi_pass  unix:/tmp/php-cgi.sock;
            fastcgi_index index.php;
            include fastcgi.conf;
        }

改为

        location ~ [^/].php(/|$)
        {
            try_files $uri =404;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            include fastcgi.conf;
        }
