+# 文件管理器 Filebrowser
+
+
+
+默认登陆用户名和密码 **_admin_** **_admin_**
+
+默认首页操作路径位置: /home/ubuntu/files  
+
+如果要更改操作路径位置，请参考下图：  
+
+设置--用户管理--编辑--目录范围（比如管理挂载盘/mnt/sda1）  
+
+![](img/filebrowser1.png)
+
+
+
+## 用户认证
+
+
+
+> **`请注意，如果盒子存在外网访问需求的，强烈建议请勿关闭认证，文件管理器不仅可以上传、下载、编辑文件，还可以执行系统命令，造成的后果自负。`**
+
+
+
+复制下面命令前往命令行窗口执行即可
+
+
+
+1. 关闭
+
+```shell
+systemctl stop filebrowser
+/opt/filebrowser/filebrowser config set --auth.method=noauth
+systemctl start filebrowser
+```
+
+2. 开启
+
+```shell
+systemctl stop filebrowser
+/opt/filebrowser/filebrowser config set --auth.method=json
+systemctl start filebrowser
+```
+
+
+
+另外，建议这个文件管理器搭配 h5ai 做分享网盘系统，分享给家人的，和自己私密的文件进行分类，简直完美。
+
+更多配置请自行前往 [filebrowser 官网](https://filebrowser.org/)查询
