Connection pool in the present embodiment is a static library forming by encapsulation, is the network communication module of the concurrent low delay of height based on Transmission Control Protocol, can be applied to the each module in operation system, for example: the each module in advertisement delivery system.Connection pool, by the each station server in server cluster is monitored, obtains online server info, selects a station server and operation system to connect from online server.
Wherein, server info can comprise: one or more information such as server label, central processing unit load, free memory.Those skilled in the art can arrange the particular content that the server info that need to obtain comprises according to the actual requirements, for example: can be by the label that only obtain server is set; Or only obtain label and the free memory information of server.Can upgrade information automatically having obtained connection pool after line server information.
Step S104: connection pool receives the request connecting with server that operation system sends.
When operation system need to connect with a certain station server, send the request connecting to connection pool, connection pool offers corresponding a connection of operation system according to the request of connecting of operation system transmission.
Step S106: the request connecting with server that connection pool sends according to operation system, selects the strategy of a selection server.
Be packaged into the strategy that comprises multiple choices server in the connection pool of static library, for example: the strategy of choosing at random a service; Select the strategy of the server of free memory maximum; Or according to multiple choices strategies such as the strategies of the server of server label size selection server label maximum.In the time that connection pool is applied in concrete operation system, need to select a kind of selection strategy, and this connection pool in the time that selecting server, postorder all to be selected to server according to this strategy.
Step S108: connection pool is according to selection strategy and line server of line server Information Selection.
Connection pool in the time being applied in operation system, corresponding a kind of strategy of selecting server, connection pool obtains this selection strategy, selects a server connecting with operation system according to the online server info obtaining simultaneously.For example: if connection pool is in the time being applied in operation system, the strategy of corresponding selection server is: the strategy of selecting the server of server label maximum according to server label size, connection pool is selecting when server so, and the server of searching server label maximum from line server information is as the server connecting with operation system.
Step S110: connection pool has judged whether to preserve the unappropriated connection example of selected line server; If preserved, perform step S112; If do not preserve, perform step S114.
In connection pool, saved each connection example is to there being socket handle, socket handle corresponding one with server between be connected.When connection pool provides connection for operation system, operation system can return to connection pool by this connection after using connection, connection pool can continue to preserve the socket handle of this connection correspondence, that is to say and can continue to preserve connection example corresponding to socket handle, can continue to safeguard with server between this be connected.
Connection pool is after having selected a server connecting with operation system, can further judge whether to preserve connection example corresponding to this server, if preserved the connection example that one or more these servers are corresponding in connection pool, whether sharedly by other connections of operation system so further judge that each connects example, if there is the connection example not taken by other connections, judge and in connection pool, have unappropriated connection example, if between all and this server of preserving in connection pool to be connected example all shared by other connections of operation system, judge and in connection pool, do not have unappropriated connection example.
Step S112: if preserved unappropriated connection example, connection pool is directly selected unappropriated connection example.
Step S114: if do not preserve unappropriated connection example, connection pool obtains a new connection example, sets up and being connected of selected line server by new connection example, adds the extremely new connection example of socket handle of this connection correspondence; The new connection example of socket handle has been added in selection.
Connection pool can be preserved newly-built this always and connect example, until this between connection pool and online server is connected disconnection.
Step S116: the request connecting with server that connection pool sends for operation system returns to operation system by socket handle corresponding selected connection example by corresponding interface, sets up being connected of operation system and selected line server according to this socket handle.
The server method of attachment based on connection pool providing by the present embodiment, monitoring server cluster in real time, and obtain the information of line server, then from online server, select a server and operation system to connect, the server that has guaranteed to offer operation system is all online, avoid in existing connection scheme, the server going wrong being offered the problem of operation system, and then guaranteed the reliability connecting.The method connecting that the present embodiment provides, the server connecting according to selection strategy and line server Information Selection and operation system, can connect task according to the present situation reasonable distribution of each online server, that has avoided existing in existing connected mode distributes to same station server by multiple connection tasks, and the problem of other server free time.The method of attachment providing by the present embodiment not only can guarantee the reliability connecting, and can also reasonably utilize the resource of each station server.
Embodiment bis-
With reference to Fig. 2, show according to the flow chart of steps of a kind of server method of attachment based on connection pool of the embodiment of the present invention two.
The concrete steps of the server method of attachment of the present embodiment comprise:
Step S202: connection pool receives the long connection of operation system input or the link order of short connection, the connection of setting up respective type according to link order.
Connection pool is packed two kinds of types that connect in the time being packaged into static library, and a kind of to connect another kind be short connection for long.Connection pool is in the time being applied in operation system, and the type that those skilled in the art can select connection pool to connect at postorder according to business scenario, is long connection or short connection.But, it should be noted that, selecting connection pool after a type all can only follow one type in the time that postorder connects.
Wherein, long being connected to: operation system can be returned this connection to connection pool after using the connection that connection pool provides, connection pool can continue to keep with server between be connected; When operation system asks to connect again, the server of selecting when connection pool or when same station server, can directly offer operation system by the connection of operation system return last time.Short being connected to: operation system can be returned this connection to connection pool after using the connection that connection pool provides, connection pool disconnect with server between this be connected; When operation system asks to connect again, the server of selecting when connection pool or when same station server, connection pool also will connect again and between server, then connection could be offered to operation system.
In the present embodiment, setting up the long example that is connected to connection pool describes the step of postorder.
Step S204: the each station server in the real-time monitoring server cluster of connection pool, obtains line server information.
In the present embodiment, connection pool is to obtain line server by the each station server in server cluster being carried out to monitoring in real time.Those skilled in the art should understand, server in connection pool can be by fixing IP(Internet Protocol, Internet protocol) address configuration is in connection pool, can also a part be configured in connection pool by fixed ip address, another part is by monitoring acquisition to server cluster.
In the present embodiment, the each station server of connection pool in real-time monitoring server cluster, when obtaining line server information, also can upgrade each server info, the line server information of obtaining in the present embodiment comprises: central processing unit load, free memory.
Step S206: whether connection pool can be used according to setting each line server of rule detection, deletes the server info that disabled line server is corresponding.
Connection pool is obtaining after line server information, can real-time or the online server of individual platform is detected every setting-up time interval.When detection, can judge whether each online server can be used by the prior mode connecting with each online server, if can successfully connect, determining server can be used, if can not successfully connect, determining server is unavailable, and connection pool can be deleted the server info corresponding to server that can not successfully connect.
Those skilled in the art can set the time interval that online server is detected according to the actual requirements, can be arranged to carry out every 10 minutes one-time detection, also can be arranged to carry out one-time detection every 5 minutes, can also be arranged to other the time interval, not do concrete restriction at this.
Step S208: the request connecting with server that connection pool sends according to operation system, select the strategy of the server of a selection central processing unit least-loaded, free memory maximum.
In connection pool, include the strategy of multiple choices server, in the time being applied in operation system, need to select a kind of strategy.Connection pool in the present embodiment has been selected the strategy of the processor of central processing unit least-loaded, free memory maximum in the time being applied in operation system.Therefore, receiving after the request connecting with server that operation system sends, connection pool provides the strategy of the server of a selection central processing unit least-loaded, free memory maximum.
Step S210: connection pool according to the strategy of selecting and one of line server Information Selection online and the server of central processing unit least-loaded, free memory maximum.
Because the strategy of connection pool corresponding selection server after being applied in operation system is the server of selecting an online and central processing unit least-loaded, free memory maximum, therefore, in the time selecting server, will from line server information, select according to this strategy a qualified server of platform.
Step S212: connection pool has judged whether to preserve the connection example of selected line server; If do not preserve, directly perform step S218; If preserved, perform step S214.
Connection pool, after having selected server, can further judge the connection example of whether having preserved this server in connection pool, and it can be also multiple wherein connect example can being one.Every station server can be set up multiple connections simultaneously, but each connects an only corresponding connection example.
Step S214: in the time having preserved the connection example of selected line server in connection pool, connection pool further judges whether the connection example of the selected line server of preserving is connected and takies by other that set up with operation system; If unoccupied, perform step S216; If occupied, perform step S218.
In connection pool, saved each connection example is to there being link information, and wherein, link information comprises: the server label of socket handle, connection status, connection.The connection example of preserving in connection pool be also equivalent to preserve in connection pool this connection example corresponding with server between be connected.One that in connection pool, may preserve selected line server connects example, also may preserve multiple connection examples, so in the time judging, judge each connection example whether by with operation system between other be connected shared, if all connection examples that selected that station server of preserving is corresponding are all occupied, to perform step S218, unappropriated if connection example corresponding to selected that station server of preserving all exists, perform step S216.
Step S216: in the time that the connection example of the selected line server of preserving in connection pool is unoccupied, directly select described connection example, execution step S220.
Step S218: if do not preserve the connection example of selected online server, or the connection example of preserving is when occupied, connection pool obtains a new connection example, set up and being connected of selected line server by new connection example, add the extremely new connection example of socket handle of this connection correspondence; The new connection example of this socket handle has been added in selection, execution step S220.
When connection pool is set up with being connected of selected line server by new connection example, adopt half asynchronous system, i.e. first unblock connects, if failure becomes block type connection.Wherein, between line server unblock and that select, connect and refer to, no matter whether connection pool, in the time connecting with selected line server, connect and set up, connection pool can also carry out other operations, for example: set up other with other servers and be connected.Block type and line server between connect and refer to, connection pool in the time connecting with selected line server, only connect set up after connection pool just can carry out other operations.
Connection pool is with after being connected of selected line server set up, connection pool can obtain the socket handle of this connection correspondence, and this socket handle is saved in corresponding connection example, this socket handle is returned to operation system and set up being connected between operation system and selected server.
Step S220: the request connecting with server that connection pool sends for operation system returns to operation system by socket handle corresponding selected connection example by corresponding interface, sets up being connected of operation system and selected line server according to this socket handle.
Setting up after being connected of operation system and selected line server, connection pool also can provide corresponding reception, transmission interface for carrying out interacting message between operation system and selected line server.The reception, the transmission interface that in connection pool, provide are provided by socket handle operation system.Between the confession operation system that connection pool provides and selected line server, carry out interacting message interface and adopt half asynchronous transmission, reception mechanism, i.e. first unblock sends or receives, if do not complete, changes block type into and sends or receive.
Operation system is using after this connection and connection can returned to connection pool, connection pool can safeguard this connection can't disconnect with selected line server information between be connected, while again initiating to ask for operation system, use.But, if server goes wrong or connection pool no longer need with server between this while being connected, connection pool disconnection is connected with selected line server, and connection pool can be deleted the socket handle in selected connection example, obtains a new connection example.
The server method of attachment based on connection pool providing by the present embodiment, first, can realize the control that length is connected, secondly, monitoring server cluster in real time, obtain the information of line server and information is upgraded, in real time or according to setting-up time interval, each online server is detected meanwhile, the corresponding server info of server that can not meet connection standard is deleted, the server that has guaranteed to offer operation system is all online and available, avoid in existing connection scheme, the server going wrong being offered the problem of operation system, and then guarantee the reliability connecting.The method of attachment that the present embodiment provides, the server connecting according to selection strategy and line server Information Selection and operation system, can connect task according to the present situation reasonable distribution of each online server, that has avoided existing in existing connected mode distributes to same station server by multiple connection tasks, and the problem of other server free time, the method of attachment providing by the present embodiment not only can guarantee the reliability connecting, and can also reasonably utilize the resource of each station server.Meanwhile, the method for attachment providing in by the present embodiment, in the time connecting with selected server, adopts half asynchronous system first to block connection, connects if failure becomes block type, has improved joint efficiency; Adopt half asynchronous transmission, reception mechanism to improve the efficiency of transmission, receipt message.
