正常我的VPS内存使用在220MB左右,由于一次折腾导致VPS重启后发现内存一直在330M左右,虽然我768MB的内存完全足够,但是对于一个有点小洁癖的人来说,无法忍受。。于是乎检查之。。。

clamd居然吃了12.6%的内存,猛然想起来这货是我装的一个杀软…卸载后完事….
接着还有iscsiuio这个东西,至于这是什么。。老谢也不知道。。man了一下,描述如下:
DESCRIPTION
iscsiuio is the UserSpace I/O driver for the Broadcom NetXtreme II BCM5706/5708/5709 series PCI/PCI-X Gigabit
Ethernet Network Interface Card (NIC) and for the Broadcom NetXtreme II BCM57710/57711/57712/57800/57810/57840
series PCI-E 10 Gigabit Ethernet Network Interface Card. The driver has been tested on 2.6.28 kernels and
above.
Refer to the README.TXT from the driver package on how to compile and install the driver.
Refer to various Linux documentations on how to configure network protocol and address.
没看懂啥意思,反正国内外论坛都搜了,说是可以关闭,不对系统造成影响,既然如此就关掉好了
chkconfig iscsi off
chkconfig iscsid off
service iscsid stop |
chkconfig iscsi off
chkconfig iscsid off
service iscsid stop
接着…..世界终于爽了………

经过一番挣扎,最终决定购买美利达550山地车,本来是打算购买捷安特ATX777,但是由于价格有点高,烧不起,于是乎在某客服忽悠下,选中了美利达550
配置为24速 M395油压碟刹 车子在配送中 到手后会发详细的实拍图 先发个网络图片YY一下
最终买了美利达公爵500!下面是实物图,2013-06-09拍摄

想在页脚加上服务器的uptime,于是乎搜相关php代码,用exec函数可以很轻松搞定,但是为了安全,该函数早在配置vps环境后就被我在php.ini里面禁用了,经过一番搜索,找到下面一段代码,希望对大家有用
调用:

<?php
function sys_linux()
{
if (false === ($str = @file("/proc/uptime"))) return false;
$str = explode(" ", implode("", $str));
$str = trim($str[0]);
$min = $str / 60;
$hours = $min / 60;
$days = floor($hours / 24);
$hours = floor($hours - ($days * 24));
$min = floor($min - ($days * 60 * 24) - ($hours * 60));
if ($days !== 0) $res['uptime'] = $days."天";
if ($hours !== 0) $res['uptime'] .= $hours."小时";
$res['uptime'] .= $min."分钟";
return$res;
}
$sysInfo = sys_linux();
$uptime = $sysInfo['uptime'];
echo$uptime;
?>
