Specific embodiment
In order to clearly understand technical scheme, the present invention is described in detail below in conjunction with the accompanying drawings.
Embodiments of the invention have an exemplary effect, those skilled in the art make on the basis of the embodiment of the present invention without essence
The improvement of property, should all belong to protection scope of the present invention.
The method of log information recording as shown in Figure 1, in can be used for PHP servers, it is comprised the following steps：
S101：Receive log information.
Before log information is received, one piece of shared memory space of first to file is used as shared buffer memory memory space.This is shared
Buffer memory space can be set according to the size of Installed System Memory, and when Installed System Memory is sufficient, shared memory space can be big
Some.General shared memory space can be 7-15KB (Ki lobyte, kilobytes), can generally choose 10KB.Shared buffer memory
If memory space crosses conference due to occupying excessive internal memory, influence the course the other parts accessed in internal memory, thus reduces
The whole efficiency of system, if shared buffer memory memory space is too small, can make log information write disk too frequent, reduce daily record letter
The efficiency of breath record.
Shared drive is referred in the environment of multi-process, there is provided give multiple process resources shared a piece of memory space, by
Independence between process, shared drive provides the scheme that a kind of each process is communicated.Process is the journey in computer
Sequence is base unit that system carries out Resource Distribution and Schedule with regard to the once operation activity on certain data acquisition system.
In PHP (Hypertext Preprocessor, the HyperText Preprocessor) server of multiple processes, have altogether
Buffer memory space is enjoyed, the multiple processes in system can just out to be temporarily stored in log information in shared buffer memory memory space.
S102：Read data cached in shared buffer memory memory space.
The data being stored in shared buffer memory memory space are referred to as data cached.Receive after log information every time, first read
It is data cached in shared buffer memory memory space, in order to judge the data cached size.
S103：Judge the data cached size.Judge the data cached size, can be in order to subsequently deciding whether
The log information for receiving is directly stored in into disk.
S104：If described data cached more than or equal to the first predetermined value, the log information is appended to
It is described it is data cached in, and by the log information and described data cached be stored in disk；Wherein, the shared buffer memory storage is empty
Between size be X, the size of the first predetermined value is Y, then Y is less than X and more than or equal to 0.75X.
According to the first predetermined value, data cached size is judged, in order to decide whether to believe the daily record for receiving
Breath is directly stored in disk, and the method can control to be stored in the data of disk by the size of setting first predetermined value.
If the first predetermined value is too little, the storage of shared buffer memory during log information recording, can be wasted
Space, will also result in write disk it is too frequent, reduce log information recording efficiency.It is stored in altogether generally for log information is improved
Enjoy buffer memory space and from shared buffer memory space reading cache data when efficiency, the size of the first predetermined value should be less than
Shared buffer memory memory space.
Such as：If shared buffer memory memory space is 10KB, the size of the first predetermined value can be 7.5KB；Work as caching
Size of data is 7.5KB, when the size of log information is 2KB, then can by the log information be appended to it is data cached in, and directly
Connect and the data message of 9.5KB is stored in disk；When data cached size is 9KB, and the size of log information is 2KB, then may be used
With by the log information be appended to it is data cached in, and directly the data message of 11KB is stored in disk.
Certainly the size of shared buffer memory memory space can also for 7KB, 8KB, 9KB, 11KB, 12KB, 13KB, 14KB,
15KB etc..If shared buffer memory memory space is 12KB, the size of the first predetermined value can be 10KB；When data cached size
For 11KB, when the size of log information is 2KB, then can by the log information be appended to it is data cached in, and directly by 13KB
Data message be stored in disk；When data cached size is 10KB, and the size of log information is 1KB, then can be by the day
Will information adding is directly stored in the data message of 11KB in disk in data cached.
S105：By the log information and it is described it is data cached be stored in after disk, empty the institute in the shared buffer memory
State data cached.
Empty described data cached in the shared buffer memory, can be directly stored in order to follow-up log information shared slow
In depositing, and raising is stored in efficiency.
The method of the log information recording in the embodiment of the present invention, its data for being stored in disk every time are greater than first and make a reservation for
The data of value, while Y is less than X and more than or equal to 0.75X, during log information recording, the Y value can make full use of
The memory space of shared buffer memory, improves buffer efficiency, simultaneously because it is data cached more than or equal to first predetermined value when, will be current
Log information and this it is data cached be stored in disk together, this can largely reduce I/O resource consumption again, improve daily record
The efficiency of information record.And the embodiment of the present invention is the shared buffer memory memory space that can be accessed using multi-process, therefore, lead to
The method is crossed, can make multi-process jointly using a buffer memory space, and arrange independent without being respectively each process
Buffer memory space, reduces the expense of internal memory, improves the execution efficiency of system and the stability of system.
Further, since the method for the log information recording of the embodiment of the present invention has used shared buffer memory, it can directly exist
PHP server internals complete the caching of the log information of multi-process, and slow for the server log information without arranging other

In deposit data, deposit data is treated in formation.
If described data cached less than the first predetermined value, illustrate to be stored in shared buffer memory memory space
It is more data cached.But needs determine whether to treat the size of deposit data.
S107：The size of deposit data is treated described in judging；If the size for treating deposit data is deposited less than the shared buffer memory
The size in storage space, then treat that deposit data is stored in the shared buffer memory memory space by described；If described treat the big of deposit data
The little size more than or equal to the shared buffer memory memory space, then treat that deposit data is stored in the disk by described.
If the size for treating deposit data is less than the size of the shared buffer memory memory space, illustrate described shared slow
Deposit to be stored in memory space and treat deposit data, therefore can will treat that deposit data is stored in shared buffer memory memory space, in order to
When being received again by other log informations, other log informations being treated into that deposit data is stored in disk together with this, therefore, both can fill
Divide and utilize shared buffer memory memory space, the number of times of write disk can be reduced again, you can disappear largely to reduce I/O resource
Consumption.
If the size for treating deposit data is equal to the size of the shared buffer memory memory space, in order to avoid due to daily record
Information be stored in shared buffer memory memory space and from shared buffer memory space reading cache data when efficiency reduction, then treat described
Deposit data is stored in the disk.

During shared buffer memory memory space can be stored in, now, current shared buffer memory memory space is taken full advantage of, therefore, it can
Directly treat that deposit data is stored in the disk by described, to reach the purpose of long-time data storage.
Such as：If shared buffer memory memory space is 10KB, the size of the first predetermined value can be 9KB；When caching number
Be 7KB according to size, when the size of log information is 2KB, then can by the log information be appended to it is data cached in, form 9KB
Treat deposit data, deposit data is treated less than 10KB shared buffer memory memory spaces due to 9kB, then this can be treated that deposit data is stored in altogether
In enjoying buffer memory space；When data cached size is 8KB, and the size of log information is 2KB, then can be by the log information
Be appended to it is data cached in, form 10KB and treat deposit data, due to 10kB to treat that deposit data is equal to the storage of 10KB shared buffer memories empty
Between, then this can be treated that deposit data is stored in the disk；When data cached size is 8.5KB, the size of log information is 2KB
When, then can by the log information be appended to it is data cached in, form 10.5KB and treat deposit data, poke treated due to 10.5kB
According to more than 10KB shared buffer memory memory spaces, then this can be treated that deposit data is stored in the disk.
