重启 uwsgi 服务。它的 log 文件位置可在以下文档找到：
http://www.iredmail.com/docs/file.locations.html
用命令：service uwsgi restart 后显示：uwsgi: 未被识别的服务
用命令：rpm -ql uwsgi* 显示：package uwsgi* is not installed
uwsgi不是安装iredmail时就安装的吗？现在是否重新安装？
安装后又要如何设置？
我用命令：yum install -y uwsgi后显示：
http://packages.inverse.ca/SOGo/nightly … epomd.xml: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'packages.inverse.ca'"
尝试其他镜像。
