腾讯云1核最低配云主机简单测评

随着海外主机打压力度的加大,本来是想准备弄个国内云主机的代理的,后来看了下代理商政策,比较繁琐。看来国内云主机商主要走的路线是自销路线。不过还是简单测评下腾讯的云主机。印象比较深刻的是,他家的磁盘IO比较给力。如果不是国内备案比较复杂,将来规模应该会非常大。除了备案这个瓶颈以外,国内的带宽费用比较贵。

以下是腾讯云简单的参数:

1、默认的centos 6 32bit:

[email protected]’s password:
[[email protected]_41_31_centos ~]# cat /etc/issue
CentOS release 6.6 (Final)
Kernel \r on an \m

[[email protected]_41_31_centos ~]# uname -a
Linux VM_41_31_centos 2.6.32-504.el6.i686 #1 SMP Wed Oct 15 03:02:07 UTC 2014 i686 i686 i386 GNU/Linux

2、磁盘:50G数据盘

[[email protected]_41_31_centos ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 7.9G 829M 6.7G 11% /

===========================

[[email protected]_41_31_centos ~]# mount -l
/dev/vda1 on / type ext3 (rw,noatime,acl,user_xattr)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
============================

[[email protected]_41_31_centos ~]# fdisk -l

Disk /dev/vda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00074875

Device Boot Start End Blocks Id System
/dev/vda1 * 1 1045 8387584 83 Linux

Disk /dev/vdb: 53.7 GB, 53687091200 bytes
16 heads, 63 sectors/track, 104025 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/vdc: 2147 MB, 2147483648 bytes
16 heads, 63 sectors/track, 4161 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

默认是系统盘和数据盘是分离的。这样做其实挺好。不过要自己挂载数据盘。

3、内存:1g 

[[email protected]_41_31_centos ~]# free -m
total used free shared buffers cached
Mem: 1006 70 935 0 3 42
-/+ buffers/cache: 24 981
Swap: 2047 0 2047

4、隐藏了CPU信息,这点其实没必要藏着掖着。阿里云就公布了CPU型号。

[[email protected]_41_31_centos ~]# cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6

fdiv_bug : no

bogomips : 5187.49
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual

5、磁盘IO。就国内云主机而言,磁盘IO相当给力了。可以和国外云主机媲美了。

dd if=/dev/zero of=test4 bs=64k count=4k oflag=dsync
4096+0 records in
4096+0 records out
268435456 bytes (268 MB) copied, 11.2687 s, 23.8 MB/s
dd if=/dev/zero of=test2 bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 3.03391 s, 354 MB/s

6、入口带宽,1Mbps,果然就这么大。出口带宽就不测了。
HTTP request sent, awaiting response… 200 OK
Length: 687075328 (655M) [application/octet-stream]
Saving to: `win2003.32.virtio.iso’

9% [==> ] 62,621,932 128K/s eta 60m 58s ^C

7、ping参考,国内主机的优势,ping很低。
