拜访：http://192.168.1.5:8082/dcs/e…
而后再拜访 http://192.168.1.6:8082/dcs/e…
会发现，192.168.1.5 的有输入日志
192.168.1.6 的没有输入日志

目前在 windows 测试通过。
在同一台电脑上，扭转端口也测试通过。

测试不通过的状况：
1）一个部署在 windows, 一个部署在 linux, windows 的缓存能够同步到 linux, linux 上的缓存无奈同步到 windows。

2）两个都别离部署在两台 linux 上，相互之间无奈同步。

以上 2 点，均在局域网，ping ip 是互通的。
