nginx: [alert] kill(12268, 1) failed (3: No such process)

运行nginx服务器时，终端下输入命令ps aux|grep nginx，正确应显示如下图：


   但是却没有显示中间nobody     3162  0.0  0.1  37228  3548 ?        S    22:58   0:00 nginx: worker process这一行，只有其它两行的状况。这样就会造成通过django管理员进入后台传到fastdfs中的图片无法通过静态网页或者img标签访问。最开始打算 卸载重新安装。(编译安装的nginx)。重装后启动nginx报如下错误：
           nginx: [alert] kill(12268, 1) failed (3: No such process)
