创建自定义 XenServer 警报

有些时候，需要监控 XenServer 某些数据时，怎么通知就变成了问题，好在，XenCenter 有个警报功能可以利用下。

命令运行在 XenServer，XenCenter会收集所有连接的服务器警报，简单监控只需要借助这个就可以，并不需要其他监控什么的 _(:з」∠)_

首先呢，查看命令提示：

[root@PnBackupServer ~]# xe help message-create
command name            : message-create
        reqd params     : name, priority, body
        optional params : vm-uuid, host-uuid, sr-uuid, pool-uuid
        description     : Create a message associated with a particular API object. Note exactly one of the optional parameters must be supplied.

[root@PnBackupServer ~]# xe help message-create

command name : message-create

reqd params : name, priority, body

optional params : vm-uuid, host-uuid, sr-uuid, pool-uuid

description : Create a message associated with a particular API object. Note exactly one of the optional parameters must be supplied.

先来试试：

[root@PnBackupServer ~]# xe message-create name="test" body="test body" priority="1"
Error: Need one of: vm-uuid, host-uuid, sr-uuid or pool-uuid

1 2	[root@PnBackupServer ~]# xe message-create name="test" body="test body" priority="1" Error: Need one of: vm-uuid, host-uuid, sr-uuid or pool-uuid

然而并不对，明明是可选参数嘛！警报对象就选本机好了：

[root@PnBackupServer ~]# xe message-create name="test" body="test body" priority="1" host-uuid=`xe host-list params=uuid --minimal`
[root@PnBackupServer ~]#

1 2	[root@PnBackupServer ~]# xe message-create name="test" body="test body" priority="1" host-uuid=`xe host-list params=uuid --minimal` [root@PnBackupServer ~]#

没有报错，搞定~

哈哈哈哈哈，其实就是刷下存在感了啦！

XenServer使用基于文件的VHD存储时，IOSTAT命令结果应如何查找对应VM

当XenServer使用基于LVM逻辑卷的VHD时，IOSTAT的结果是酱紫的：

[root@xenserver-PDS330 ~]# iostat

Debian安装JDK6

网上所说的:apt-get install sun-java6-jdk

执行完全不行,提示找不到这个包,估计是需要添加源吧!.

今天有个客户说让我帮忙安装Java6,没安过,没的说,直接百度,

结果千篇一律,全都是一样的安装文章,不知道有没有尝试过就安装,反正我是没安装成功.

还是Google好用:

up vote1down vote

Try this:

to install Java Development Kit(jdk)

# apt-get install sun-java6-jdk

1	# apt-get install sun-java6-jdk

or the Java runtime environment (jre):

# apt-get install sun-java6-jre

1	# apt-get install sun-java6-jre

Source: https://wiki.debian.org/Java/Sun

Package is missing, has been obsoleted, or is only available from another source. However the following packages replace it: sun-java6-demo. I guess I’ll have to add squeeze back to my sources. –

源地址说:这个包已经丢失,或者废弃,可以用sun-java6-demo代替

还有一篇:

1down vote

Run sudo apt-cache search java6 to get a list of packages available from the default repositories. If you don’t see anything you like, you will have to either add an apt repository or install java manually.

源地址说:运行apt-cache search java6获取匹配列表,如果看到你需要的,执行安装就可以了.

要的就是这个,因为上面那个解决方案是用的sun-java-demo,虽然我并不知道是干嘛的,但是有个demo单词,还是不装的好.

搜索Java6相关的包:

root@MyServer:~# apt-cache search java6
default-jdk - Standard Java or Java compatible Development Kit
default-jre-headless - Standard Java or Java compatible Runtime (headless)
default-jre - Standard Java or Java compatible Runtime

openjdk-6-jre - OpenJDK Java runtime, using Hotspot JIT

安装:

root@MyServer:~# apt-get install openjdk-6-jdk

完成:

查看运行在XenServer下的所有VM名称、UUID以及dom-id

在XenServer中,使用sar -n DEV 1 1命令查看各VM的网络状态,内含的vif{数字},实际为dom-id.

删除使用XenCenter导入模板时断网产生的坏系统模板

损坏的系统模板最直接的表现是不可以使用XenCenter删除:

与正常模板的区别就是:

废话不说,

service xapi restart

1	service xapi restart

再次连接就可以删除了.

吐槽迅雷……

先算一下：

24×60×60×30=2592000s
2592000×2=5184000MB
5184000/1024=5062.5GB

24×60×60×30=2592000s

2592000×2=5184000MB

5184000/1024=5062.5GB

最近用一直闲置的enzuVPS做了个下载站，用于方便我维护，但是最近发现流量有点异常。

平均两天左右就可以制造出一个80MB的日志，而我每次看的时候网卡流量都是2MB/s左右（这还是我限制后的结果）。

虽然美国的VPS口子大，但也不能便宜了这帮使用迅雷的兔崽子，而且我的本意就是只给朋友用（部署VPS等），因为他们用的都是美国的，所以到底应不应该屏蔽迅雷就很明显了，怀着这个念头找了下资料，迅雷的UA分别有：

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; )
Mozilla/5.0  (compatible; MSIE 6.0; Windows NT 5.0)
Mozilla/4.0 (compatible; MSIE  6.0; Windows NT 5.0; .NET CLR 3.5.20706)
Mozilla/4.0 (compatible;  MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; )

Mozilla/5.0 (compatible; MSIE 6.0; Windows NT 5.0)

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 3.5.20706)

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)

我总觉得，迅雷的UA应该不止这些，或许他调用的是ie，UA即为IEUA（这个只是怀疑，真实性有待考证）。

不过这个真心无所谓，VPS最次也是IE7，IE6的滚蛋，即使你不用迅雷我也不想给你下（做网站的都明白……）

下面是我写的屏蔽语句：

#干死迅雷....
#Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; )
if ($http_user_agent ~ "Mozilla/4.0\ \(compatible;\ MSIE\ 6.0;\ Windows\ NT\ 5.1;\ \)")

{ 
	return 444; 
}

#Mozilla/4.0 (compatible; MSIE  6.0; Windows NT 5.0; .NET CLR 3.5.20706)
if ($http_user_agent ~ "Mozilla/4.0\ \(compatible;\ MSIE\ 6.0;\ Windows\ NT\ 5.0;\ .NET\ CLR\ 3.5.20706\)")
{ 
	return 444; 
}

	return 444;
}

#干死迅雷....

#Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; )

if ($http_user_agent ~ "Mozilla/4.0\ $compatible;\ MSIE\ 6.0;\ Windows\ NT\ 5.1;\ $")

{

return 444;

}

#Mozilla/5.0 (compatible; MSIE 6.0; Windows NT 5.0)

if ($http_user_agent ~ "Mozilla/5.0\ $compatible;\ MSIE\ 6.0;\ Windows\ NT\ 5.0;$")

{

return 444;

}

#Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 3.5.20706)

if ($http_user_agent ~ "Mozilla/4.0\ $compatible;\ MSIE\ 6.0;\ Windows\ NT\ 5.0;\ .NET\ CLR\ 3.5.20706$")

{

return 444;

}

#Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)

if ($http_user_agent ~* "Mozilla/4.0\ $compatible;\ MSIE\ 6.0;\ Windows\ NT\ 5.1;\ SV1;\ .NET\ CLR\ 1.1.4322;\ .NET\ CLR\ 2.0.50727$") {

return 444;

}

我用的是Nginx，据有关资料描述，使用方法是这样的：

1.将其保存至/etc/nginx/getout.conf
2.在网站配置文件中使用include包含至配置中

我的配置是：

server { # Generated by VPSMate
    limit_rate 2048k;
    limit_conn addr 2;
    listen 80;
    server_name download.myluoluo.com;
    charset gbk;
	#封锁迅雷,开始
	include /etc/nginx/agent.conf;
    #封锁迅雷结束
    index index.html index.htm index.php;

    location / {
        root    /home/wwwroot/download.myluoluo.com;
        autoindex   on;
    }

}

server { # Generated by VPSMate

limit_rate 2048k;

limit_conn addr 2;

listen 80;

server_name download.myluoluo.com;

charset gbk;

#封锁迅雷,开始

include /etc/nginx/agent.conf;

#封锁迅雷结束

index index.html index.htm index.php;

location / {

root /home/wwwroot/download.myluoluo.com;

autoindex on;

}

不过事与愿违，被屏蔽后流量确实为0了，但是现在又满了，同时出现了以下UA：

XenServer 6.1安装笔记

首先要说一下，不是在实体机安装的，是在虚拟机安装的。

下载光盘：官方下载

本文中使用的为：XenServer 6.1安装光盘。

注意：安装时会删除硬盘上的所有数据。。。。小心哦～

光盘引导界面：

提示你，安装或者升级请按<Enter>键，也就是回车键。

F1-标准 F2-高级

回车后，经过一系列的检查，进入下面这个选择键盘映射的屏幕：

这里默认选择的是[qwrty] us，我们平时使用的键盘也是即为美式键盘，所以，直接回车，进入下一个屏幕：

这里提示你，如果继续将会删除所有数据（翻译肯定不准，不太会，望理解），按下回车键：

许可协议，按下Tab键，切换到Accept EULA，回车：

这一步就很重要啦，它说你的电脑不支持Virtualization（也就是VT）或者这一功能被禁用，你需要去BIOS内启用它。

当然，这一项应该是默认启用的，如果它提示着一个，大多数都是不支持的，坏处是不支持虚拟Windows系统的。。。

好了，跳过他：

注：当高亮时，可以使用空格键选择硬盘。

好吧，又是一个坑。。。好智能 = = 居然还会坚持是不是虚拟硬盘。。。。好吧，本来就是虚拟机，回车：

选择安装方式，支持网络安装，但是。。。用网络安装干嘛？so，Local Media，然后回车：

没看懂这个，建议，不要被误导，按照推荐选项来：Yes，回车：

这一步就是验证安装媒介了，第一个是跳过，第二个是验证，默认是第二个选项，这里选择第一个：跳过，回车：

该到设置密码的步骤了，要求即为大于等于6的密码（生产环境强烈建议密码设置为大小写+特殊字符）输入密码后，回车：

配置网络，即设置IP地址，一般机房都有DHCP的，不过还是建议手动设置，也就是Static configuration，输入完毕后，回车：

主机名以及DNS配置，国外服务器的DNS强烈建议设置为Google DNS的：8.8.8.8 and 8.8.4.4，设置好后，回车：

选择时区，Asia（亚洲）回车->Shanghai（没有北京，选择上海时间），回车：

设置系统时间，建议使用手动输入，当然，如果你能找到可用的NTP服务器也可以用NTP，选择第二项，回车：

好了，终于到了开始安装的时候了，截图与打字快累死了。。= =，选择Install XenServer，回车：

没图了。。。安装过程懒得截图了。。。

这里应该是因为之前选择了安装补充包，咱没有。。。Skip～囧：

到了设置时间的时候了，根据前面的提示，提示设置时间时，就应该是要结束安装了：

好了，已经安装完成了，现在可以把光盘从驱动器中移除了～然后按回车键重启服务器：

好了，熟悉的界面出现咯^^

如果想管理该服务器下的VM，还需要安装XenCenter：

下载地址：download.myluoluo.com（此为中文版，不信我的可以从官方下载）

估计看官也看出来了，我也是新手，写这篇文章的目的就是熟悉XenServer的安装过程^_^

文中如有错误的地方，还请及时指正，以免误导其他朋友～

至此，安装结束～

转载不表明原文地址的，请斩掉你那脏手，永远不要踏足笨笨.Blog，这里不欢迎你。

当Linux reboot重启失效时Input/output error

reboot bash: /sbin/reboot: Input/output error 
shurdown -r now bash: /sbin/shutdown: Input/output error

1 2	reboot bash: /sbin/reboot: Input/output error shurdown -r now bash: /sbin/shutdown: Input/output error

Input/output error这段说的已经很清楚了,输入输出错误,也就是说磁盘I/O错误.

如果说,这台服务器就在你身边,那么你可以很明确的告诉他,你给我马上重启,不重启弹你小鸡鸡…好吧,然后咚一声,他关机了..

但是,如果这货远在美国呢？给机房发重启请求，好点的机房十几分钟就好了，垃圾的机房要等一天甚至两天。。

so，自力更生才是最正确的。。

以下方法需要需要Magic SysRq key(CONFIG_MAGIC_SYSRQ)支持持才行，可以使用命令来测试：

grep CONFIG_MAGIC_SYSRQ  /boot/config-$(uname -r)

1	grep CONFIG_MAGIC_SYSRQ /boot/config-$(uname -r)

常见的发行版貌似已经激活了这个功能，但是不排除没有启用的可能。。。。

当返回y时请继续阅读 or 您还是慢慢等吧

将Magic SysRq key配置为接受所有SysRq请求

echo 1 > /proc/sys/kernel/sysrq

1	echo 1 > /proc/sys/kernel/sysrq

需要重启时，执行：

echo b > /proc/sysrq-trigger

1	echo b > /proc/sysrq-trigger
