gearman.errors.ServerUnavailable: Found no valid connections in list: [<GearmanConnection localhost:4730 connected=False>]

从error log的最后一行ServerUnavailable，可以看出是Gearman的server被停掉了。

1.当我执行gearmand -d命令时，先是提示/var/log/gearman/gearman.log不存在，所以先在这个路径下创建一个log文件；

2.启动本机的Server，端口是4730，命令是：

 gearmand --log-file gearmand.log --listen 127.0.0.1 --port=4730 --verbose=INFO &
