你这估计是操作系统没打开端口。

你搜索一下自己对应的系统如何打开端口。
比如：

Use this command to find your active zone(s):

firewall-cmd --get-active-zones
It will say either public, dmz, or something else. You should only apply to the zones required.

In the case of dmz try:

firewall-cmd --zone=dmz --add-port=2888/tcp --permanent
Otherwise, substitute dmz for your zone, for example, if your zone is public:

firewall-cmd --zone=public --add-port=2888/tcp --permanent
Then remember to reload the firewall for changes to take effect.

firewall-cmd --reload
