+安装软件包：`lm-sensors`、`lm-sensors-detect`
+
+修改 `/usr/libexec/rpcd/luci` 文件，添加一个 `ubus` 的 `method`：
+<pre style="font-family: 'SF Mono', consolas, Menlo, 'PingFang SC', 'Microsoft YaHei', monospace; font-size: 13px; line-height: 24px; white-space: break-spaces">

+        end
+    },
+</span>
+    getTimezones = {

+
+<!-- more -->
+
+修改 `/usr/share/rpcd/acl.d/luci-base.json` ，给刚刚添加的 `getCPUInfo` 添加权限：
+

+
+使用命令 `/etc/init.d/rpcd restart` 重启 `rpcd` 服务，最后清除浏览器页面缓存。
+
+PS：可使用 `ubus call luci getCPUInfo` 检查执行是否有异常。
