4, source access evidence need to be returned again by breaing up rear cache server, and facing inter-network at this time, transprovincially network is slow or even link
The problems such as interruption, influences customer experience.
To solve the above-mentioned problems, the embodiment provides a kind of server data caching method, device and it is
System.One group of shared buffer memory server, buffered first cache server of data of utilization are configured for hot spot URL access request
As data cached data source, the second cache server in other shared buffer memory server groups is to first cache server
The data for requesting it to cache have carried out maximum utilization, effective solution to the data of the first cache server caching
The problem of more cache servers pull excessive bandwidth resource consumption caused by L2 cache or Hui Yuan, time delay, realizes
Rapidly and efficiently, reliable and stable access hot spot load balancing.
First in conjunction with attached drawing, the embodiment of the present invention one is illustrated.
The embodiment of the invention provides a kind of server data caching method, using this method to the flow of hot spot URL into
The process that row breaks up caching process is as shown in Figure 3, comprising:
Step 301, ethernet device detect the working condition of the cache server of rear end, synchronous with other ethernet devices
To the detection result of the working condition of the cache server；
During the present invention is implemented, the ethernet device is specially Switch server, cache server concretely Cache
Other servers such as server or tengine server, squid server with caching function.It is taken in this step with Cache
It is illustrated for business device, specific as follows:
1, Switch server judges whether the URL access request configures the machine hash and shared buffer memory configuration (shows this
Whether URL access request supports shared buffer memory server group).It works in default mode if not.If there is altogether
Cached configuration is enjoyed, then is entered in next step.
2, the spy of one rear end cache server of the internal maintenance of each Switch server pond living, wherein comprising available
Whole cache servers.(such as: serve port is the working condition of each primary each cache server of detection cycle detection
It is no normal), it is that abnormal cache server is rejected from spy pond library living, and is synchronized to other Switch by detection result
Server.
Switch definition distribution rear end is this group of hash or the machine hash mode, and calculation formula is stored in proxy mould
After block, custom feature can not be completed.Because caching must calculate to exist in this group and delay in shared buffer memory server group
That machine IP deposited, then needs to extract out the algorithm, while also to match rear end and visit in function living while a synchronous group
Chained list, other interior Switch of guarantee group are not in problem when being URL the machine hash, avoid arriving URL access request hash
On the cache server of delay machine or flow is run on full cache server.
It should be noted that this step and subsequent each step have no strict sequential order relationship, the spy to rear end cache server
Sustainable progress is surveyed, at any time synchronized update.
Step 302, when detecting the URL access request for meeting preset draining conditions, ethernet device be the URL
Access request configures shared buffer memory server group；
In the embodiment of the present invention, the shared buffer memory server group includes first cache server and at least one the
Two cache servers.First cache server and second cache server are identical cache server, only
When being configured in same shared buffer memory server group, the first cache server can carry out Hui Yuan as specified cache server
Or to pull the operation of L2 cache data cached to obtain, the second cache server is then obtained from first cache server and is cached
Data.Same cache server may be slow as first in the configuration of the shared buffer memory server group of different URL access requests
Deposit server, it is also possible to as the second cache server.The embodiments of the present invention also provide a kind of server data cachings to be
System, framework is as shown in figure 4, Switch server distributes URL access request, shared buffer memory server group shared buffer memory data, LVS
Request uniformly can be published to Switch server in any case as the equal balance system of front end load by SiteServer LBS
On.More Switch servers constitute Switch and distribute Request Systems, calculate in the shared Cache server group of rear end that there are the
The IP address of first cache server is sent to other the second cache servers by one cache server, is shared slow in group
Deposit configuration section.The information that the second cache server in shared Cache server group is sent according to Switch server, Xiang Tong
The first cache server of group fetches data.L2 cache mitigates back source pressure as caching buffer system.Hot spot URL is accessed
After request is broken up, using distributed frame, configuring hot spot URL is shared cache mode in group, directly improves every Cache service
The bearing capacity of device solves the problems, such as before hot spot URL occurs.
This step specifically includes:
1, the corresponding cache server of configuration the machine is first cache server；
2, according to preset shared buffer memory algorithm, determine that other are assigned to the ethernet device of the URL access request；
3, configuration it is described other be assigned to the URL access request ethernet device it is corresponding and working condition is normal
Cache server be second cache server.
The URL access request for meeting draining conditions is alternatively referred to as hot spot URL, is confirmed by business.It can be client
It informs, such as to do the request of some movable page today can be very big.Or the URL request number is very big, by server into
Journey, cpu resource etc. exhaust, and are considered as hot spot URL.
Step 303, the ethernet device notify each second cache server to pass through first buffer service
Device obtains the data cached of the URL access request.
The IP address of first cache server is sent to each second buffer service by the ethernet device
Device.
It is still illustrated for framework shown in Fig. 4, before Switch server calls consistent hashing module calculates
There are the IP address of that data cached the first cache server, and a head share_loop:IP is arranged and passes through respectively
Switch server gives each cache server.It algorithm will extract before, then using synchronous address pool as input number
According to calculating the IP of first cache server, which notified to each cache server, can guarantee so same shared
The second cache server in cache server group is all to the first cache server access evidence.
Step 304, cache server receive the notice that ethernet device is sent；
In this step, the notice includes the configuration to the shared buffer memory server group.According to the configuration, can determine
The identity of this cache server is the first cache server or the second cache server.Further, which is a head
Share_loop:IP carries the IP address of the first cache server.
Cache server saves the IP of notice instruction.For example, can be by defining dynamic_catch module for head
IP information in portion is taken out, and there are in variable CacheIP.
Step 305, cache server check the shared buffer memory server group of the URL when receiving URL access request
Configuration；
In this step, when receiving URL access request, whether the data of this of logic judgment URL have existed the machine
Caching, if there is direct returned data data.If the machine be not present with the URL it is associated data cached, be configured as in the machine
When the second cache server, first cache server of the cache server into the shared buffer memory server group obtains institute
State the data cached of URL access request.Specifically, preserving the IP address of the first cache server and the machine non-in the machine
When one cache server, 306 are entered step, is requested to the IP address data cached.There is no shared buffer memory server in the machine
When group configuration or the machine are the first cache server, 307 pulling datas are entered step.
It is still illustrated by taking the citing in step 304 as an example, the dynamic of cache server fills Cache_src function mould
Block obtains CacheIP variate-value, confirms that IP service is normal by the spy function living between Cache, otherwise directly returns higher level's section
Point obtains caching.
Step 306, when the machine is configured as the second cache server, the cache server takes to the shared buffer memory
The first cache server in business device group obtains the data cached of the URL access request.
Still it is illustrated by taking the citing in step 304 as an example, in this step, the Cache_request mould of cache server
The IP address that block is stored into CacheIP, which initiates similar source of going back to, requests, and fetches data while not transmitting share_loop head, avoids
Cause endless loop.
Step 307, when the machine is not configured the shared buffer memory server group into the URL, to L2 cache or source number
Source operation is carried out back according to station, is obtained data cached.
With reference to the accompanying drawing, the embodiment of the present invention two is illustrated.
The present invention provides a kind of server data caching system, framework is as shown in figure 4, the system is predicting hot spot
In the case of URL exists or in the case of the URL of interim burst hot spot, URL need to be modified plus shared buffer memory configuration and the machine in group
Hash setting configures shared server group for the URL.
S1: hot spot URL is evenly distributed on Switch server to a certain extent by the equilibrium of LVS front end load.It is false
If falling on B server.
S2: Switch detects the URL and is configured with the machine hash algorithm and organizes interior shared buffer memory at this time, then counts in systems
Calculating two values, (the machine hash value, determination transmit the request to D.Calculating this group of hash value simultaneously, i.e. there are the one of caching
Platform server hypothesis is A).
S3: request is directly passed to E cache server by Switch system at this time, while taking a share-
(shared buffer memory function in Cache enabling group is told in share_loop expression to the header value of loop:D_IP, and D_IP is to calculate
There are the D servers of caching).
S4:B cache server internal judgment first whether there is the caching of the URL, if there is direct returned data.Such as
Fruit does not have, then takes out the D_IP in share_loop, and synchronous to D cache server request data.
S5:B Cache quick obtaining data in Intranet, and cache portion, directly solve to need back L2 cache or
Source station access according to the problem of.
