openwrt - NVRAM集合

如何使用
　　telnet登录openwrt后，第一次使用nvram的话，尝试一下 nvram show 命令（加上回车），将列出所有的nvram参数。

　　第二步仍然是尝试一下，用　nvram get flash_type 看看FLASH芯片是什么型号的，但这台7231-4p却无法看到型号。

　　我这里学习nvram的主要目的是用来设置的，设置命令是 nvram set ，完整的写法是“nvram set 参数=值”，我用一个例子说明。

　　参数设置后，必须使用 nvram commit 进行保存，如果有必要，还需要 reboot 命令重启设备，使新修改的参数生效。


设置方面的一个例子----修改路由器内网IP地址
　　把 LAN 的 IP 由 192.168.1.1 改为 192.168.1.9，可执行：

　　nvram set lan_ipaddr=192.168.1.9
　　nvram commit
　　reboot

　　第1行是修改IP地址，第2行是保存，第3行是重新启动 OpenWrt ，因为更改IP地址后要重启才能生效。


命令列表

---

nvram show
- 列出 nvram 所有参数

nvram show | grep 参数
- 用附加的 grep 命令来抽取部分参数，例如 nvram show | grep lan_  意思就是取出关于LAN方面的参数

nvram get flash_type
- 取得FLASH芯片型号

nvram set 参数=值
- 设置用，见例子

nvram unset 参数
- 删除参数，例子：要删除 dr_lan_rx=0 ，执行：nvram unset dr_lan_rx ，不需要值

nvram commit
- 保存，若否，则路由器重启后，这些修改便会丢失

reboot
- 重启硬件，非nvram系列命令，不是一定必要，但大多数情况会用到

这是安装openwrt后，最初的 nvram ，没有任何改动，感觉应该不齐全
