如果刚刷的openwrt18点多的没有中文界面，用ssh连接路由后用opkg安装

root@openWRT:~# opkg install luci-i18n-base-zh-cn

Unknown package 'luci-i18n-base-zh-cn'.
Collected errors:
opkg_install_cmd: Cannot install package luci-i18n-base-zh-cn.

找不到安装包

这时需要更新一下opkg环境

root@openWRT:~# opkg update

显示：有Signature check passed.的项表示更新成功。

更新成功后执行

root@openWRT:~# opkg install luci-i18n-base-zh-cn

这样就安装成功了，进入网页，System=>System=>Language and Style=>Language 选择中文，重新登录即可。
