module(“luci.controller.admin.index”, package.seeall)

function index()
local root = node()
if not root.target then
root.target = alias(“admin”)
root.index = true
end

local page = node(“admin”)
page.target = firstchild()
page.title = _(“Administration”)
page.order = 10
page.sysauth = “root”
page.sysauth_authenticator = “htmlauth”
page.ucidata = true
page.index = true

— Empty services menu to be populated by addons
entry({“admin”, “services”}, firstchild(), _(“Services”), 40).index = true

entry({“admin”, “Free_Memory”}, call(“Free_Memory”), _(“Free Memory”), 89)
entry({“admin”, “logout”}, call(“action_logout”), _(“Logout”), 90)
end

function action_logout()
local dsp = require “luci.dispatcher”
local sauth = require “luci.sauth”
if dsp.context.authsession then
sauth.kill(dsp.context.authsession)
dsp.context.urltoken.stok = nil
end

luci.http.header(“Set-Cookie”, “sysauth=; path=” .. dsp.build_url())
luci.http.redirect(luci.dispatcher.build_url())
end
function Free_Memory()
luci.util.exec(“echo 3 > /proc/sys/vm/drop_caches”)
luci.http.redirect(luci.dispatcher.build_url(“admin”, “status”, “overview”))
end

黑色加粗部分。

另在 luci/trunk/luci/luci/po/zh_CN/base.po 最底部添加

msgid “Free_Memory”
msgstr “释放内存”

这样使用中文的时候便能显示中文。

没必要吧 op不占很多内存的

echo 3 > /proc/sys/vm/drop_caches会导致数据丢失的。需要用 sync && echo 3 > /proc/sys/vm/drop_caches

这东西意义不大，反而影响进程加载速度和IO

现在可以直接使用LEAN的插件包，不必再修改文件。
