Abstract
The invention relates to the cloud calculating technology field and particularly relates to a virtual machine remote desktop management method suitable for public cloud. According to the method, firstly a server of a cloud platform is taken as a front end and is further distributed with a public network IP, and the server is further equipped with one port mapping tool; after a virtual machine is established on a host computer, a remote desktop port to which the virtual machine is distributed is queried through a tool of a virtualization platform; an unused port is distributed to the front end, a rule is written into the port mapping tool, and all the requests sending to the port at the front end are forwarded to the corresponding remote desktop portion of the host computer; the virtual machine is accessed by utilizing a remote desktop client through the public network, through a mode of a front end public network IP + the distribution port, the remote desktop of the virtual machine can be accessed. The method solves problems of huge remote desktop management IP resource occupation of the public cloud virtual machine and low safety and is applicable to virtual machine remote desktop management of the public cloud.
Description
Technical field
The present invention relates to field of cloud computer technology, refer to a kind of virtual machine remote desktop management method being applicable to publicly-owned cloud especially.
Background technology
In publicly-owned cloud platform, be exactly distribute public network IP to each virtual machine for the optimal management method of virtual machine remote desktop, use corresponding remote desktop client, by the remote desktop of the direct accesses virtual machine of public network IP self.Can public network IP limited amount, this mode is for inapplicable large-scale publicly-owned cloud, and in addition, this mode depends on the network of virtual machine itself, VME operating system do not start complete or remote desktop service does not start time, can not connect.
Said method derives from the remote desktop management method of traditional IDC, be applicable to virtual machine and physical machine simultaneously, in addition, because general virtual platform utilizes the remote desktop of host to carry out managing virtual machines, based on this feature, therefore, generally the step that manages of the special remote desktop for virtual machine is as follows:
1, a public network IP is joined to every platform host;
2, for the remote desktop service end of each virtual machine on host distributes different ports on host;
3, by the mode of " host public network IP+port ", corresponding remote desktop client is used to be connected to the remote desktop of corresponding virtual machine.
Said method compares saving public network IP relative to distributing a public network IP to each virtual machine, can also bring following drawback:
1, every platform host all independent face to public network, once wherein a certain receive attack, all can have influence on the safety of all hosts and its lower virtual machine, under publicly-owned cloud environment, apply said method can cause the fail safe of whole publicly-owned cloud platform to decline;
2, management dispersion, accesses the remote desktop port that each virtual machine all needs to search separately virtual machine belonging to it and use.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of virtual machine remote desktop management method being applicable to publicly-owned cloud, solves that to take public network IP many, the problems such as host fail safe is not high.
The technical scheme that the present invention solves the problems of the technologies described above is:
Comprise the steps:
Step 1: select a publicly-owned cloud platform station server wherein as front end and distribute a public network IP, and a port mapping instrument is installed thereon;
Step 2: host creates after virtual machine, by its remote desktop port be assigned to of tool queries of virtual platform;
Step 3: distribute a untapped port on front end, and in port mapping instrument, write is regular, by all remote desktop port of request forward to the correspondence on host mailing to this port of front end;
Step 4: when using remote desktop client accesses virtual machine on public network, has access to the remote desktop of virtual machine by the mode of " port of front end public network IP+distribution ";
Step 5: after virtual machine is deleted, the mapping ruler that the port mapping instrument of front end finds virtual machine corresponding is also deleted.
The untapped port that described front end is distributed is the general port of 5 figure places, is not the port that special port or system retain.
The open port distributed in described front end; In front of host, end is in same local area network (LAN) simultaneously, and host can follow front end communication.
Described port mapping instrument is newly-increased or come into force after deleting a rule, can not have influence on existing rule.
The beneficial effect of the present invention program is as follows:
1, front-end server of the present invention only needs configuration public network IP, by the desktop of this public network IP remote access to all virtual machines; Only use a public network IP, farthest can save valuable public network IP resource.
2, method of the present invention only has a station server towards public network, as long as carry out to this server the safety system that security protection can improve whole system, is relatively safe implementation.
3, method of the present invention can be managed concentratedly the access port of all virtual machines, can reduce the maintenance workload of keeper.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is flow chart of the present invention.
Embodiment
First, select a wherein station server of publicly-owned cloud platform as front end, be furnished with a public network ip, concrete steps are as follows:
(1) front end download port mapping tool rinetd installing, realizes port mapping/forwarding/be redirected.
#cd/root
#wget http：//www.boutell.com/rinetd/http/rinetd.tar.gz
#tar zxvf rinetd.tar.gz
#cd/root/rinetd
#make
#make install
(2) front-end edit/etc/rinetd.conf configuration file, distributes port and configured port mapping ruler.
[root@gcloud17～]#vi/etc/rinetd.conf
0.0.0.0 21500 192.168.3.215 5900
0.0.0.0 21501 192.168.3.215 5901
0.0.0.0 21502 192.168.3.215 5902
0.0.0.0 21503 192.168.3.215 5903
Profile parameters illustrates:
This file often row comprises 4 parameters, is respectively:
The port of the address connection of the port connection of the address binding of binding
0.0.0.0 21500 192.168.3.215 5900
0.0.0.0: represent any address, i.e. all machines of the Internet
5900: the remote desktop serve port representing virtual machine
This record represents 5900 ports of request forward to 192.168.3.215 any address being mail to front end 21500 port.
(3) front-end machine starts rinetd process
#rinetd-c/etc/rinetd.conf
In addition, this order can be added to/etc/rc.local inside realize start and automatically run.
(4) by remote desktop client, such as vnc goes the access public network IP of front-end machine and the port of distribution, just can be long-range to the virtual machine on this host of 192.168.3.215, carries out safeguarding and managing virtual machines.
(5), after virtual machine is deleted, the port mapping instrument of front end find mapping ruler corresponding to this virtual machine and deletes, then restarting rinetd process.
First kill falls rinetd process, then restarts
#pkill rinetd
#rinetd-c/etc/rinetd.conf。
