通过一键部署 bash seafile-server-centos-7-amd64-http 7.1.3
到最后一步启动Seahub服务时，报错启动失败：
LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub at port 8000 …
Error:Seahub failed to start.
Please try to run “./seahub.sh start” again
再通过调试运行启动，报错信息如下：
LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub (fastcgi) at 127.0.0.1:8000 …
Traceback (most recent call last):
