Detailed Description
The core of the application is to provide a method, a device, equipment and a readable storage medium for detecting continuously available IP addresses, which are used for reducing the manpower consumption of detecting the continuously available IP addresses at most and improving the detection efficiency.
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, a flowchart of a method for detecting a continuously available IP address according to an embodiment of the present application is shown, where the method for detecting a continuously available IP address according to the embodiment of the present application may include:
s11: and acquiring continuous IP addresses distributed by the target data center machine room, and continuously numbering the continuous IP addresses.
In performing the continuously available IP address detection, first, it is necessary to determine a target data center room to be subjected to the continuously available IP address detection. The determining mode may specifically be that the user sends a continuous available IP address query command of the target data center room (the query command may include information such as an identifier or a name of the target center room), and then determines the target data center room according to the received continuous available IP address query command of the target data center room sent by the user, where, of course, the target data center room may also be obtained through automatic query.
After determining the target data center room, the continuous IP addresses allocated to the target data center room may be automatically acquired, where the continuous IP addresses mentioned herein may specifically be allocated to the target data center room by the system actively, or may be allocated by a user of the target data center room actively.
After automatically acquiring the continuous IP addresses allocated to the target data center room, the continuous IP addresses allocated to the target data center room may be automatically numbered: referring to fig. 2, a schematic diagram of a continuous number corresponding to a continuous IP address allocated to a target data center room in the embodiment of the present application may be shown, that is, a first IP address in the continuous IP addresses is numbered as first, and a second IP address in the continuous IP addresses is numbered as first+1 … …, so as to facilitate detection of continuously available IP addresses according to the continuous number of the continuous IP addresses, and improve convenience and accuracy of detection of continuously available IP addresses by continuously numbering the continuous IP addresses.
For the convenience of detection, the first, first+1, … …, last are integers, and the first may or may not be 1, that is, when the assigned consecutive IP addresses are consecutively numbered, the consecutive IP addresses may be consecutively numbered 1, 2, … … from 1 (i.e., the first IP address in the consecutive IP addresses is numbered 1, and the second IP address in the consecutive IP addresses is numbered 2 … …), or the consecutive IP addresses may be consecutively numbered 2, 3, … … from an integer (e.g., 2) other than 1 (i.e., the first IP address in the consecutive IP addresses is numbered 2, and the second IP address in the consecutive IP addresses is numbered 3 … …).
Through the continuous numbering of the continuous IP addresses, the corresponding relation between each IP address and the number in the continuous IP addresses can be obtained, so that the detection of the continuous available IP addresses is conveniently carried out based on the corresponding relation.
S12: and acquiring the IP addresses in the continuous IP addresses occupied by the physical nodes in the target data center machine room, and recording the numbers corresponding to the occupied IP addresses in the continuous IP addresses in the used array.
After the continuous IP addresses allocated to the target data center machine room are numbered continuously, the IP addresses in the continuous IP addresses occupied by the physical nodes in the target data center machine room can be acquired automatically, namely the occupied IP addresses in the continuous IP addresses allocated to the target data center machine room are acquired. Then, the number corresponding to the occupied IP address in the continuous IP address may be determined according to the correspondence between the IP address and the number in the continuous IP address, and the number corresponding to the occupied IP address in the continuous IP address may be recorded in the used array. Where used i indicates that the IP address is already occupied and the used array used may be unordered.
After the used array used is obtained, the number of the numbers existing between any two adjacent numbers in the numbers contained in the used array used is the number of the continuous available IP addresses, so that the determination of the maximum continuous available IP address information can be carried out through the used array used later.
S13: adding a minimum record number and a maximum record number into the used array according to the minimum number and the maximum number corresponding to the continuous IP address; wherein the minimum record number is smaller than the minimum number by 1, and the maximum record number is larger than the maximum number by 1.
Considering that the first and last IP addresses of the consecutive IP addresses, i.e., the IP addresses numbered first and last, are ignored when the number corresponding to the occupied IP address of the consecutive IP addresses is recorded in the used array used only for the determination of the most consecutive available IP addresses, in order to improve the accuracy of the detection of the most consecutive available IP address information, the minimum record number and the maximum record number may be added in the used array used according to the minimum number and the maximum number corresponding to the consecutive IP addresses, specifically, the minimum record number added in the used array used is smaller than the minimum number corresponding to the consecutive IP addresses by 1, i.e., the minimum record number added in the used array used is smaller than first by 1, i.e., the minimum record number added in the used array used is first-1; the maximum record number added in the used array used is 1 greater than the maximum number corresponding to the continuous IP address, i.e., the maximum record number added in the used array used is 1 greater than last, i.e., the maximum record number added in the used array used is last+1. For example: assuming that the used array used obtained through step S12 is used= [ b, a, d, c … … ], the used array used obtained after step S13 is used= [ first-1, b, a, d, c … …, last+1].
S14: and determining the maximum continuous available IP address information corresponding to the target central machine room according to the used array.
After the minimum record number and the maximum record number have been added to the used array used, the maximum continuous available IP address information corresponding to the target central machine room may be determined according to the used array used, specifically, the determination of the maximum continuous available IP address information corresponding to the target central machine room may be performed according to two adjacent numbers in the numbers included in the used array used, so as to automatically determine the maximum continuous available IP address information corresponding to the target central machine room.
According to the method and the device, continuous numbering is carried out on the continuous IP addresses automatically, numbers corresponding to occupied IP addresses in the continuous IP addresses are recorded in the used array automatically, the minimum recorded number and the maximum recorded number are added in the used array automatically, and finally continuous available IP address information corresponding to a target central machine room is detected automatically, rapidly and accurately without manual participation, so that manpower consumption in the process of detecting the maximum continuous available IP address information can be reduced, labor cost is reduced, accuracy and efficiency of detecting the maximum continuous available IP address information are improved, and research, development and testing efficiency can be greatly improved.
According to the technical scheme disclosed by the application, the continuous IP addresses distributed to the target data center machine room are numbered continuously, the IP addresses in the continuous IP addresses occupied by the physical nodes in the target data center machine room are obtained, the numbers corresponding to the occupied IP addresses in the continuous IP addresses are recorded in the used array, the minimum record number which is 1 smaller than the minimum number corresponding to the continuous IP addresses and the maximum record number which is 1 larger than the maximum number corresponding to the continuous IP addresses are added in the used array, and the maximum continuous available IP address information corresponding to the target center machine room is determined according to the used array, so that the automatic detection of the maximum continuous IP addresses is realized without manual participation, the manpower consumption in the detection process of the maximum continuous IP addresses is reduced, the detection efficiency and the detection accuracy of the maximum continuous IP addresses are improved, the quick deployment of the application is facilitated, the stability of the data center is ensured, the management cost investment of the data center is reduced, and the user experience is improved.
The method for detecting the continuous available IP address provided by the embodiment of the application can determine the maximum continuous available IP address information corresponding to the target central machine room according to the used array, and can comprise the following steps:
sequencing the numbers contained in the used arrays according to the order of the sizes to obtain sequenced used arrays;
acquiring number numbers contained between two adjacent numbers in the ordered used array, and determining the maximum number as the maximum number of continuous available IP addresses corresponding to the target central machine room;
and determining the IP address corresponding to the maximum number of the continuous available IP addresses according to the adjacent two numbers corresponding to the maximum number in the ordered used array and the number corresponding to the continuous IP addresses.
In the present application, when determining the maximum available IP address information corresponding to the target central office according to the used array, in order to improve the convenience and efficiency of determining the maximum available IP address information corresponding to the target central office, the numbers included in the used array may be first sorted according to the order of sizes (specifically, the order may be from small to large, or the order may also be from large to small), so as to obtain the sorted used array. Then, the number of numbers included between two adjacent numbers in the ordered used array may be obtained, for example: assuming that there are two adjacent numbers 2 and 6 in the ordered used array, the number of numbers included between the two adjacent numbers can be determined to be 3. After the number of the numbers contained between every two adjacent numbers in the ordered used array is determined, the maximum number is determined as the maximum number of the continuous available IP addresses corresponding to the target central machine room. Meanwhile, each IP address corresponding to the maximum number of available IP addresses can be determined according to two adjacent numbers corresponding to the maximum number in the ordered used array and the number corresponding to the continuous IP addresses (namely, the numbers corresponding to each IP address in the continuous IP addresses, namely, the corresponding relation between each IP address in the continuous IP addresses and the number), specifically, each IP address corresponding to the number existing between the adjacent two numbers corresponding to the maximum number in the ordered used array is determined as each IP address corresponding to the maximum number of available IP addresses, so that a related person can not only obtain the maximum number of available IP addresses corresponding to the target data center machine room, but also determine each IP address corresponding to the maximum number of available IP addresses, and further, the related person can conveniently perform subsequent operation and use based on the obtained information.
For example: for simplicity, assuming that a target data center room is assigned 8 consecutive IP addresses, the 8 numbers of 2-9 are obtained by consecutively numbering the 8 consecutive IP addresses, wherein the IP addresses numbered 4 and 6 are already occupied, the ordered used array is [1,4,6,10] by recording, adding the minimum recording number and the maximum recording number, and ordering, and the number of the two numbers 2 and 3 contained between the two adjacent numbers 1 and 4 in the ordered used array is obtained, the number of the one number 5 contained between the two adjacent numbers 4 and 6 in the ordered used array is obtained, the numbers of the numbers 7, 8 and 9 contained between the adjacent two numbers 6 and 10 in the ordered used array are obtained, so that the maximum number of numbers is 3, at this time, the maximum number of continuous available IP addresses corresponding to the target central machine room can be determined to be 3, and the IP address corresponding to the maximum number of continuous available IP addresses can be determined according to the numbers of the adjacent two numbers 6 and 10 and the numbers of continuous IP addresses corresponding to the maximum number of numbers 3 in the ordered used array, specifically, the IP addresses corresponding to the three numbers 7, 8 and 9 respectively existing between the adjacent two numbers 6 and 10 are determined to be the IP addresses corresponding to the maximum number of continuous available IP addresses.
The method for detecting the continuously available IP address provided by the embodiments of the present application, for obtaining the number of numbers included between two adjacent numbers in the sequenced used array, may include:
subtracting two adjacent numbers in the ordered used array, taking an absolute value of the difference value obtained by subtraction, and subtracting 1 from the absolute value to obtain the number of the numbers contained in the two adjacent numbers.
In the present application, when obtaining numbers included between two adjacent numbers in the ordered used array, specifically, the two adjacent numbers in the ordered used array may be subtracted, then, an absolute value is taken for a difference obtained by the subtraction, and then, the absolute value is subtracted by 1 to obtain numbers included in the two adjacent numbers, for example: and if two adjacent numbers in the ordered used array are x and y respectively, the number of the numbers contained between the two adjacent numbers of x and y can be obtained by adopting |y-x| -1. Of course, the number of numbers included in two adjacent numbers in the used array can be obtained by directly subtracting 1 from the smaller number from the larger number in the two adjacent numbers.
By the method, the number of the numbers contained between two adjacent numbers in the ordered used array can be rapidly calculated.
Taking the application as an example of sorting the numbers contained in the used array according to the order from small to large to obtain the sorted used array, the core codes for obtaining the number of the largest number contained between two adjacent numbers in the sorted used array are specifically as follows:
the method for detecting the continuously available IP address provided by the embodiment of the present application may further include, after obtaining the number of numbers included between two adjacent numbers in the ordered used array:
and determining the number of the numbers contained between two adjacent numbers in the sequenced used array as the number of the continuous available IP addresses corresponding to the target central machine room.

In addition, while the number of numbers included between two adjacent numbers in the ordered used array is determined as the number of continuous available IP addresses corresponding to the target central machine room, corresponding IP addresses corresponding to the number of continuous available IP addresses except the number of continuous available IP addresses in the ordered used array can be determined according to the number of adjacent two corresponding numbers and the number of continuous IP addresses corresponding to the number of continuous available IP addresses in the ordered used array, so that related personnel can acquire each IP address corresponding to the number of continuous available IP addresses, and the related personnel can select and use the IP addresses according to requirements conveniently.
