Without that should be limited by embodiments set forth here.Conversely, there is provided these embodiments are able to more thorough
Ground understand the present invention, and can by scope disclosed by the invention it is complete convey to those skilled in the art
Member.
Below in conjunction with accompanying drawing, the technical scheme that various embodiments of the present invention are provided is described in detail.
Fig. 1 is the process according to the information acquisition method of the embodiment of the present invention, and the executive agent of the process can be with
Server, more specifically, should during the step of can be on server process perform.The clothes
Business device can be Web server, application server etc., and the process can specifically be to provide the process of service,
By taking Web server as an example, its process for providing service can be fast page mode (fast page mode, fpm)
Process etc..The present invention is not limited the type of server.
Server is connected with each other (connection herein refers to physical connection) with zookeeper, there is one on server
Or multiple processes that service is provided, there is process configuration information in zookeeper, configured when renewal process is needed
During information, can be updated by the process configuration information in zookeeper, realized on server
The process configuration information of each process is automatically updated.It should be noted that with zookeeper be connected with each other
Server can be with more than one, and each server can respectively perform the process in Fig. 1.Below in Fig. 1
Process illustrate.
Process in Fig. 1 may comprise steps of：
S101：Each process robs lock, and the lock is the lock between default process.
In the embodiment of the present invention, process may need related configuration information in the process of running, by these phases
The configuration information of pass is referred to as process configuration information.When each process will obtain process configuration information, Ke Yikai
Begin to perform step S101.
The lock is lock between process, including but not limited to file lock, System V signals amount lock, Read-Write Locks,
Mutual exclusion lock etc..The lock may be used at most to have in each process a process to get specific operation to be weighed
Limit, in embodiments of the present invention, specific operation authority can set up the authority that length is connected with zookeeper.
S202：Rob the successful process of lock to be connected with zookeeper foundation length, by the connection long set up
Shared drive to the server is monitored, the process configuration information in shared drive is monitored with
When process configuration information in the zookeeper is inconsistent, the process configuration in the zookeeper is obtained
Information, and be updated in the shared drive, so that the process for robbing lock failure is obtained according to the shared drive
Process configuration information；Wherein, the shared drive is shared by each process that service is provided on the server.
In embodiments of the present invention, server local can also preserve process configuration information, server local
Process configuration information can be it is being pre-configured with by the keeper of server, or by process from
What zookeeper was preserved again after obtaining.Process configuration information in zookeeper is that newest process matches somebody with somebody confidence
Breath, when will to update process configuration information when, it is possible, firstly, to the process configuration information in zookeeper
It is updated, then, for the process configuration information of server local, then can be according in zookeeper
Process configuration information after renewal is correspondingly updated, so that, each server being connected with zookeeper
Local process configuration information can realize synchronization.
Server local can specifically refer to the shared drive of server and/or the local disk of server.In shared
The advantage deposited is fast read or write speed, is easy to rob each process quick obtaining process configuration information of lock failure, locally
The advantage of disk can be power-off storage, and reliability is higher.As can be seen here, in order to improve acquisition configuration information
Real-time, can preferentially in shared drive preserve and update process configuration information.
In actual applications, if not having process configuration information when initial in shared drive, lock is robbed successful
Process can immediately obtain the process configuration information in zookeeper after long connection is set up with zookeeper,
And preserve to shared drive, hereafter, process configuration information and zookeeper in shared drive is monitored
In process configuration information it is inconsistent when, it is believed that the process configuration information in zookeeper there occurs more
Newly (the process configuration information in zookeeper is always newest process configuration information), and then, can obtain
The process configuration information in zookeeper is taken, is correspondingly carried out with to the process configuration information in shared drive
Update, it is thus possible to realize that shared drive is synchronous with the process configuration information in zookeeper.
In embodiments of the present invention, connection long is such communication connection：Can be continuous in the communication connection
Multiple packets are sent, if temporarily sent without packets need, can be detected with transmission link and wrapped, with
The communication connection is set to remain in that connection rather than disconnection.Relative with connection long is short connection, and short connection is
Such communication connection：Multiple packets can be continuously transmitted in the communication connection, if temporarily without data
When bag needs to send, then the communication connection is disconnected.
According to explanation above, due to robbing the successful process of lock during monitoring, it may be necessary to more than once
Ground obtains newest process configuration information from zookeeper, therefore, rob the successful process of lock and zookeeper
The connection of foundation can grow connection, successfully enter in order to rob lock by this within long period of time
Journey is responsible for obtaining newest process configuration information from zookeeper.Certainly, in actual applications, more long
A period of time in, it is also possible to the process in Fig. 1 is performed a plurality of times, in this case, robs lock successfully every time
Process be likely to difference.
By the above method, connected due to need to only there is a process to keep long with zookeeper on each server
Connect, you can to cause that each process that service is provided on the server can get newest process with confidence
Breath, and to be kept with zookeeper respectively without each process on each server as prior art
One connection long, therefore, it can effectively mitigate the load of zookeeper, and reduce to zookeeper
Process performance influence.
In order to make it easy to understand, further being illustrated to the step in Fig. 1 below.
For step S102, robbing the successful process of lock can start a thread, or start a process, so
Afterwards by the thread for starting or the process, set up length with zookeeper and be connected.The advantage of former scheme
It is to be started without extra process, smaller is born to server；The advantage of latter scheme is entering for new startup
Journey and to rob the successful process of lock be separate, not shared resource, therefore, the new process for starting will not
The efficiency that the successful process of lock provides service is robbed in influence, the new process for starting with rob the successful process of lock can phase
The newest process configuration information that mutually transmission is obtained.In actual applications, selection can be needed more according to scene
Suitable scheme.In inventive embodiments, it is specifically described mainly for former scheme.
According to one embodiment of the present of invention, when using above-mentioned former scheme, for step S102
Length is set up with the zookeeper to be connected, can specifically include：Start an asynchronous thread；By starting
Asynchronous thread, with the zookeeper set up length be connected.Wherein, had the advantage that using asynchronous thread：
Length is set up in the asynchronous thread with zookeeper to be connected and the follow-up mistake for monitoring and obtaining process configuration information
Cheng Zhong, the asynchronous thread whenever send an operation requests, be not necessarily required to wait zookeeper response after,
Corresponding operating or other operations could be performed, and can be during waiting zookeeper to respond, i.e.,
Other operations can be performed, it can be seen that, the operating efficiency of asynchronous thread is higher, and then is also beneficial to improve
The execution efficiency of the solution of the present invention.
It should be noted that asynchronous thread is based only on one kind that thread realizes the implementation method of step S102
Example, step S102 can also be equally realized using synchronizing thread.
According to one embodiment of the present of invention, it has been mentioned hereinbefore that rob the successful process of lock from
After zookeeper gets newest process configuration information, the process configuration information that will preferentially can be obtained is more
It is new in the shared drive of server.Because compared to shared drive, the reliability of disk is higher can be powered off
Storage, therefore, in order to further improve the reliability of the solution of the present invention, for step S102, rob lock
After in process configuration information update to the shared drive of server that successful process will be obtained, can also carry out
Following steps：Will obtain zookeeper in process configuration information update to the local disk of server in.
Like this, the process configuration information in the process configuration information and shared drive in local disk can be each other
Backup, reliability is higher.
Rob lock failure each process can be got from the local disk of server and/or shared drive it is newest
Process configuration information, specifically, process configuration information preferentially can be obtained from shared drive, works as shared drive
In the presence of it is abnormal (process configuration information is not preserved in shared drive such as, or, preserved process configuration letter
Breath by by mistake delete, etc.) lead to not from shared drive obtain process configuration information when, then can according to this
Local disk obtains process configuration information.
According to one embodiment of the present of invention, for step S102, each process of lock failure is robbed according to described common
Enjoy internal memory and obtain configuration information, can include：For each process for robbing lock failure, the process may determine that
Whether process configuration information is had in shared drive, if so, the process configuration information in shared drive is then obtained,
Otherwise, the local disk according to server obtains process configuration information.
In actual applications, not only shared drive may occur exception, local disk it can also happen that exception,
Such as, the data on local disk are by deletion etc. by mistake.When each process for robbing lock failure both cannot be from shared drive
Acquisition process configuration information, when also cannot obtain process configuration information from local disk, then can be by robbing lock
The part or all of process of failure directly from zookeeper servers or is robbed the successful process of lock and obtains process and match somebody with somebody
Confidence ceases.
Continue to use upper one embodiment of the invention to go on to say, rob the process of lock failure according to the local of server
Disk obtains process configuration information, can specifically include：The process for robbing lock failure judges this earth magnetism of server
Whether process configuration information is had in disk；If so, then obtaining the process configuration information in local disk；Otherwise,
Short connection is set up with zookeeper, by the short connection set up, the process obtained in zookeeper matches somebody with somebody confidence
Breath, and the short connection is closed after process configuration information is got.
Due to set up the short process configuration information of getting that is connected to can immediately close off, i.e., it is short connection maintain when
Between it is shorter, therefore, even if each process sets up a short connection with zookeeper, compared to prior art,
The burden brought to zookeeper is smaller.
Further, if any process for robbing lock failure is got by the short connection set up from zookeeper
Process configuration information, then the process configuration information update that the process will can get to shared drive and/or sheet
In local disk.Like this, other processes for not yet getting process configuration information can be from server local
Acquisition process configuration information, without obtaining process configuration information by way of short connection setting up again.
According to one embodiment of the present of invention, for each process that server is provided on server, process initiation
Afterwards at any time in, whenever process get process configuration information (usually newest process match somebody with somebody confidence
Breath), the process configuration information operation that the process can get according to this.
By the above method, the process of process configuration information, server local in zookeeper matches somebody with somebody confidence
The process configuration information of breath and each process operation foundation can realize synchronization, and synchronous real-time is preferable.
According to one embodiment of the present of invention, in the implementation process of the solution of the present invention, may have simultaneously
More than one process carries out the read-write operation for process configuration information to shared drive or local disk, in order to
The situation for preventing these parallel read-write operations from process configuration information may be caused to malfunction, can be to this earth magnetism
Process configuration information in disk and shared drive is also plus the lock (such as Read-Write Locks) between process so that same
Moment, most only one of which processes (are occupied the process of the Read-Write Locks, can be the connections long by setting up
The process of the process configuration information for getting, or the process got by the short connection set up are configured
The process of information) write operation can be performed, and in the implementation procedure of write operation, do not allow other processes to hold
Row read operation, occupy the Read-Write Locks process performed write operation after, the Read-Write Locks can be discharged.
Fig. 1 has been described in detail above.In order to make it easy to understand, the present invention is also based on a kind of practical application
Scene, is contrasted, as shown in Figure 2 and Figure 3 to the solution of the present invention with the scheme of prior art.
The practical application scene is illustrated first.In the practical application scene, Web server (can be with
Have one or more, one be shown in which in this embodiment) it is connected with each other with zookeeper, Web service
There are multiple fpm processes on device, there is the process configuration information that fpm processes can be used on zookeeper.
Fig. 2 is that each fpm processes obtain the connection diagram long set up during process configuration information in the prior art.
In figure 2 it can be seen that each the fpm process on Web server is set up with zookeeper respectively
One connection long, for obtaining newest process configuration information from zookeeper.Therefore, zookeeper
A large amount of connections long, heavy load, influence treatment will be for a long time maintained between server and each Web server
Performance.
Fig. 3 is the connection signal long set up when each fpm processes obtain process configuration information in the solution of the present invention
Figure.
It is seen in figure 3 that only one of which fpm processes (are robbed in i.e. each fpm processes on Web server
Lock successful fpm processes) establish connection long with zookeeper.During this is within the survival time of connection long,
Can be responsible for obtaining newest process configuration information from zookeeper by fpm processes always, and will obtained
Process configuration information update enters to the shared drive and local disk of Web server in order to other fpm
Journey is obtained.When initial, process configuration information can be preserved in shared drive and local disk, it is also possible to not
Preserve process configuration information.Obviously, in compared to the prior art in Fig. 2, the side of the invention in Fig. 3
Case each Web server only need to set up a connection long with zookeeper, effectively alleviate
The burden of zookeeper, reduces the influence to the process performance of zookeeper.
