通过一站式安装完jumpserver后，启动jumpserver就会过几分钟服务自动stop，这是为什么。

OneLogin have updated their UI, we should re-run our docs and update images.

Currently, I must specify a username for a host in aker.ini. This is a convenient feature in some scenarios, but it would be nice if Aker would default to the user's username for the connection and optionally allow the user to specify a different username if he or she wanted.

As an example, consider the following:

[supertylerc]
hosts = 10.0.0.1,22
    192.168.0.1,22,admin

centos7，照着“一步一步安装”那一页教程来的，每次启动coco都报如下错误：
(py3) [root@localhost coco]# ./cocod start -d
Use eventlet dispatch
2019-01-28 11:10:24 [terminal ERROR] The name have been used: localhost.localdomain
2019-01-28 11:10:24 [service ERROR] Failed register terminal

我把配置文件conf.py里的NAME字段改成test或者AAA这样的字符串，仍然会出现
The name have been used:AAA这样的错误。
