最后的解决办法把nginx的版本降低（原先是1.2.1现在是1.0.5）

未将版本前的日志：

具体步骤：
     wget http://bj.download.ijinshan.com/yunwei/nginx-1.0.5.tar.gz  ##下载nginx的源码包
    tar xzf nginx-1.0.5.tar.gz  ##解压
   cd nginx-1.0.5 ##进入nginx目录
   /usr/local/nginx/sbin/nginx -V  ##查看nginx的编译参数
   ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-openssl=/usr/local/openssl（此参数是上面查到的）
   make && make install（安装）
   ll -tr /usr/local/nginx/sbin/nginx* ##你看到有nginx和nginx.old
   ps -ef | grep nginx  ##查看当前的nginx的master的进程号
   kill -USR2 25518  ##从容切换到新的nginx
   tail /data/logs/apns.ijinshan.com.log ##查看是否支持中文
