修改配置，实现web远程登录

cd /root/.config/syncthing/

vi config.xml

<address>0.0.0.0:8384</address>

而后就可以使用web页面进行配置。初始页面如下：

然后就可以点击右上角的Action->Setting选项进行配置，如果我们在内网使用，就可以关闭发现、中继和升级等的选项。

点击首页Folder栏目下的Add Folder按钮，用以添加同步的目录。在需要同步的两台服务器上都进行文件夹配置，此处我们使用Syncthing同步http访问的session信息。

下面的步骤就是用于连接两台的服务器了。首先在其中一台查看device id，也在右上角的Action-> Show ID菜单下。

复制到Device ID后，到另一台服务器的控制页面，点击右下角的Add Device按钮。按如下输入对端的信息。其中Addresses栏直接填写对端服务器的IP地址加22000端口。22000端口为默认配置，可以在cconfig.xml文件中进行更改。

一旦配置完成一台服务器，起来去上个厕所，回来后就可以发现另一条服务器的控制页面会出现连接请求，直接点击Add Device即可。

然后，按照同步的时间间隔，默认为60秒，等看到Device和Folder状态都变成Up to Date之后，就表明两台服务器之间的同步机制就建立完成了。
