1、怎么查看自己的vps是否安装了directadmin
咨询你的vps运营商
2、如何查看当前vps的虚拟化技术
|Update: You may be interested in [[the perl mole|perl-mole-for-virtualization-detection]] implementing these tricks.
Frequently, our customers want to install our software in a virtual machine. This can be OK, but frequently they hit a CPU, memory, or IO limit caused by running in a constrained virtual environment. When this happens, we really like to know if they're running under virtualization when we try to support them. Here's some tricks to detect, from a shell, if the system is virtualized.
The first thing to check is dmesg. On a recently-booted system, checking the 'dmesg' command output may be sufficient. Otherwise, try "cat /var/log/dmesg" instead of "dmesg"
VMWare:
# dmesg | grep -i virtual VMware vmxnet virtual NIC driver Vendor: VMware Model: Virtual disk Rev: 1.0 hda: VMware Virtual IDE CDROM Drive, ATAPI CD/DVD-ROM driveQEmu or KVM:
If the "-cpu host" option has not been used, QEmu and KVM will identify themselves as:
# dmesg | grep -i virtual CPU: AMD QEMU Virtual CPU version 0.9.1 stepping 03otherwise, the host's CPU information will be used both in dmesg, or in /proc/cpuinfo.
However, you should see something like:
$ dmesg | grep -i virtual [ 0.000000] Booting paravirtualized kernel on KVMon newer kernels that understand that they're running under paravirtualization. (Thanks to René Pfeiffer for pointing this out)
Microsoft VirtualPC:
# dmesg | grep -i virtual hda: Virtual HD, ATA DISK drive hdc: Virtual CD, ATAPI CD/DVD-ROM driveXen (thanks, wardi and others)
# dmesg | grep -i xen Xen virtual console successfully installed as tty1Virtuozzo
# dmesg (returns no output) # cat /var/log/dmesg (returns no output) # ls -al /proc/vz veinfo veinfo_redir veredir vestat vzaquota vzdataOn longer-running systems, you may need to grep /var/log/dmesg instead.
If that doesn't proce anything useful, try using dmidecode to look at the BIOS information. Frequently, there will be at least one component identifying itself as virtualized:
VMWare:
# dmidecode | egrep -i 'manufacturer|proct' Manufacturer: VMware, Inc. Proct Name: VMware Virtual PlatformMicrosoft VirtualPC:
# dmidecode | egrep -i 'manufacturer|proct' Manufacturer: Microsoft Corporation Proct Name: Virtual MachineQEMU or KVM:
# dmidecode | egrep -i 'vendor' Vendor: QEMUVirtuozzo:
# dmidecode /dev/mem: Permission deniedXen:
# dmidecode | grep -i domU Proct Name: HVM domUYou should just examine the output of dmidecode directly rather than trying to grep as above, in case the output changes. QEMU, for example, doesn't report the vendor in all versions.
Next, check disk devices for identification as virtualized:
VMWare:
# cat /proc/ide/hd*/model VMware Virtual IDE CDROM Drive # cat /proc/scsi/scsiAttached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: VMware Model: Virtual disk Rev: 1.0 Type: Direct-Access ANSI SCSI revision: 02Microsoft VirtualPC:
# cat /proc/ide/hd*/model Virtual HD Virtual CDQEMU, KVM, or Xen:
# cat /proc/ide/hd*/model QEMU HARDDISK QEMU DVD-ROMVirtuozzo:
# ls -al /dev/vzfs b-----x--- 1 root root 0, 19 2009-04-06 15:04 /dev/vzfsIf you've got tips for other virtualized environments, let me know and I'll add them to the list.
3、VPS网速查询,ping查询方法,怎么看自己的VPS是否掉线?
从你的截图来看.现在VPS是不通的.除非你设置了禁PING.否则这个时候你是打不开网站的.出现网络不通的情况.大多是由于机房的网络故障或者是死机造成的.需要找你的服务商协助解决.
而网站平时访问速度慢的原因就比较多了.比如说最常见的机房网络不稳定.网站程序出错.网站首页加载内容过多.网站访问量大导致CPU或者带宽跑满.被攻击等.建议你在IP可以PING通的情况下.找各个地区的朋友帮你做下测试.也可以借助于卡卡测速网这样的网站来测试全国各地.各种线路用户访问你网站的速度.并做下路由追踪.看到在哪一个环节出现了问题. 4M是指的带宽.带宽主要是决定了你网站同一时间能承载的最多访问量.假如你的网站目前只有很小的访问量.那么带宽的大小并不会直接影响到你网站的访问速度.你也可以登录服务器.然后在任务管理器中查看联网.里面会显示带宽的使用情况.
4、怎样才能看出来自己使用的是独立服务器还是vps
VPS 在系统设备管理器里是看不到CPU 的而且VPS 的主服务器一般都是性能很好的 志强CPU XEON 这样的CPU 在 任务管理器里。显示的 CPU表 最差也是 2个双核志强。那就是4个表如果你看到的 只有1个。或者 CPU 是 双核志强。但是任务管理器里只有2个表。那肯定就是VPS 了
5、怎么看自己VPS是否是双线的呢?
其实无法自己在系统里查看所用VPS线路的. 但可以用其他的一些方法.比如说用PING命令做下PING值测试.电信与网通互访的速度比较慢.如果你是用的双线的话.那么无论你用电信PING还是用网通PING.结果都不会相差太多.另外也可以在百度上输入你的IP搜索看下.如果是电信或者网通单线的话.一般会显示机房所在地的名字.但如果是双线的话.一般显示的是机房运营商的名字.
希望以上回答对你有所帮助.大家有服务器相关问题需要帮忙的可以找我
6、如何得到我的VPS信息
VPS购买成功 一般在管理查询查询VPS产品信息
如IP 内存等等!
