Distributed File storage System (DFS) means that physical storage resources managed by a File System are not necessarily directly connected to a local node, but are connected to a node (which can be simply understood as a computer) through a computer network; or a complete hierarchical file system formed by combining several different logical disk partitions or volume labels. DFS provides a logical tree file system structure for resources distributed at any position on the network, so that users can access shared files distributed on the network more conveniently. The role of individual DFS shared folders is relative to access points through other shared folders on the network.
Load balancing builds on existing network architectures and provides an inexpensive, efficient, transparent way to extend the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and increase network flexibility and availability. Load Balance means that the Load Balance is shared by a plurality of operation units to be executed, such as a Web server, an FTP server, an enterprise key application server and other key task servers, so as to jointly complete work tasks. The global load balancing has the characteristics that: 1. the response speed of the server is improved, the problem of network congestion is solved, and the effect of high-quality network access is achieved. 2. The system can provide complete transparent service for users in a long distance, and truly realizes independence from geographical positions. 3. The method can avoid various single-point failures, including single-point failures of a data center, a server and the like, and also including single-point failures caused by private line faults.
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be a domain name coordination system with load balancing access.
As shown in fig. 1, the method includes:
In order to facilitate understanding of the present invention, the following further describes the method for coordinating domain names accessed by load balancing according to the principle of the method for coordinating domain names accessed by load balancing of the present invention and in combination with the process of coordinating domain names accessed by load balancing in the embodiment.
The existing load balancing method comprises the following specific steps:
(1) if the client accesses the domain name test.com, the server receives the domain name test.com, automatically adds a ". just.", i.e.. just.test.com ", in the front of the first domain name in the configuration file by the server, then matches the first domain name" test.com ", namely judges whether the" test.com "contains the". test.com ", if not, then matches the received domain name" test.com "by using the" test.com "in the configuration file, matches the first domain name with the second domain name" test.com ", matches the first domain name with the second domain name successfully, and selects an ip to the client according to a polling strategy (round-bind) corresponding to the domain name test.com.
(2) If the client accesses the domain name bucket.test.com, the server receives the domain name bucket.test.com, automatically adds a ". quadrature.", namely,. test.com ", in front of the first domain name in the configuration file by the server, and then matches the first domain name bucket.test.com" with the received domain name bucket.test.com ", namely, judges whether the" bucket.test.com "contains the". test.com ", if yes, an ip is selected to the client according to a polling strategy (round-robin) corresponding to the domain name test.com.
(3) From (1) and (2), it can be determined that, when the domain names test.com and bucket.test.com exist in the configuration file at the same time, no matter which domain name the client accesses, the server selects an ip to the client according to a round-robin policy (round-robin) corresponding to the domain name test.com.
Specifically, the method for coordinating a load balancing access domain name provided by this embodiment includes:
s1, setting the priority of the sub domain name higher than the upper domain name of the sub domain name in the domain name configuration file, and setting the load balancing rule of the domain name and the load balancing rule of the sub domain name.
Setting a priority function configuration item, starting a priority management function through the configuration item, wherein the priority of the sub-domain is higher than that of the domain in the starting state of the priority management function; in the priority function not enabled state, the domain name is higher in priority than the sub-domain name.
The setting of the priority function configuration item is a preferred technical solution of this embodiment, and in other embodiments of the present invention, the sub domain name is directly set to have a priority higher than the upper normal domain name.
Adding a priority function configuration item, wherein the specific adding method is that < checksubdomain checksubdomain = 'true' > represents a sub-domain name resolution function switch; when the checksubdomain is true, starting a sub-domain name resolution function; when the checksubdomain is false, closing the sub-domain name resolution function; < subdomainpfriority = "true" > denotes a sub domain name resolution priority switch; when the subdomainpreference is true, the sub-domain name is analyzed preferentially; when the subdomainpriority is false, the normal domain name is analyzed preferentially; < domain name = "test.com" > means that the domain name is test.com; < domain name = "bucket.
After the addition is completed, the configuration item is enabled, and the configuration item is normally set to be in a state of being preferentially resolved by the sub-domain name by default.
And S2, analyzing the domain name information of the request sent by the client, and if the domain name information contains the domain name and the sub-domain name, distributing the service node ip for the client according to the load balancing rule of the sub-domain name. And if the domain name does not have the sub domain name in the domain name information, distributing the service node ip for the client according to the load balancing rule of the domain name.
If the domain name exists in the domain name information, marking the domain name, and searching a lower-level sub-domain name of the domain name from the domain name information; and if the subordinate sub-domain name of the domain name in the domain name information is found, distributing the service node ip for the client according to the load balancing rule of the sub-domain name.
(1) Com if the client accesses the domain name test
The first round adopts sub-domain name matching: and the server receives the domain name as test.com, automatically adds a ". multidot.", namely,. test.com ", in the front of the first domain name in the configuration file, and then matches the first domain name with the received domain name,. test.com", namely, judges whether the "test.com" contains the ". multidot.com", and does not. Then, the second domain name "bucket.
And the second round adopts normal domain name matching: com, the server side directly matches the first domain name in the configuration file with the received domain name "test.com", and if the first domain name is the same as the received domain name "test.com", an ip is selected to the client side according to a polling strategy (round-robin) corresponding to the domain name test.com.
(2) Com if the client accesses the domain name packet
The first round adopts sub-domain name matching: the server receives a domain name of bucket.test.com, automatically adds a ". multidot.", namely,. test.com ", in front of a first domain name in a configuration file by the server, then matches the first domain name with the received domain name of bucket.test.com", namely, judges whether the "bucket.test.com" contains the ". multidot.com", and then selects an ip to the client according to a polling strategy (round-robin) corresponding to the domain name of bucket.test.com.
(3) If the client accesses the domain name a.packet.test.com
The first round adopts sub-domain name matching: the server receives a domain name of a.bucket.test.com, segments the a.bucket.test.com at intervals of 'say', namely, the a.bucket.test.com is four segments, automatically adds a 'say', namely, 'test.com' in front of the first domain name in a configuration file, then matches the first domain name with the received domain name 'a.bucket.test.com', namely, judges whether the 'bucket.test.com' contains 'test.com', and returns the same segment number of 2.
Automatically adding a ". multidot.", namely ". bucket.test.com", in the front of the second domain name in the configuration file, and then matching the second domain name with the received domain name "a.bucket.test.com", namely judging whether the "a.bucket.test.com" contains ". multidot.bucket.test.com", and returning the same number of segments as 3.
And traversing the whole configuration file in sequence, and selecting the domain name with the largest segment number, namely selecting an ip to the client according to a link number strategy (link) corresponding to the second domain name bucket.
S3, collecting basic information of each service node of the cluster, wherein the basic information comprises average CPU utilization rate, memory utilization rate and bandwidth utilization rate; and selecting a target service node according to the basic information of each service node and the current load balancing rule, and distributing the target service node ip to the client.
Firstly, selecting a node in a server cluster as a DNS node, wherein all nodes collect data of the node, the data comprises the number of connection numbers, average cpu utilization rate, memory utilization rate and bandwidth utilization rate (polling and Hash strategies do not need to collect the data), all nodes send the collected data to the DNS node, the DNS node stores the collected data in a memory, and when a client accesses a domain name, the DNS calculates and returns a virtual ip to the client according to strategies corresponding to the domain name, a sub-domain name function switch, a sub-domain name priority switch and the like.
Calculating a virtual ip flow for the DNS according to the configuration parameters under the domain name, the sub-domain name function switch, the sub-domain name priority switch and the like;
(1) when the DNS is started, a configuration file is loaded first, and information such as a sub-domain name resolution switch, a sub-domain name priority, a domain name, a strategy and the like in the configuration file is stored in a memory;
(2) the DNS receives a domain name resolution request of a client, and the DNS extracts a domain name to be accessed by the client;
(3) the DNS reads a sub-domain name function switch and a sub-domain name priority switch which are stored in a memory:
1. if the sub-domain name resolution function is started, a sub-domain name priority switch is started:
traversing all domain names in the configuration file, adding a mark in front of the domain name in the configuration file (such as a mark in 2. com), matching the domain name with the domain name accessed by the client, calculating the number of matched segments of the domain name if the domain name is matched, and storing the matched segments of the domain name and the position of the comparison domain name in the configuration file in a memory, wherein the position of the domain name of the configuration file in the configuration file (the position of a first domain name in the configuration file is 0, the position of a second domain name in the configuration file is 1, and the positions are sequentially downward); and the DNS calculates according to the parameters and the strategy under the domain name and returns a virtual ip of the address pool under the domain name to the client.
If the configuration files are not matched after traversing, directly comparing the domain name in the configuration files with the domain name accessed by the client in the second round, judging whether the domain names are the same or not, and if the domain names are the same, returning the position of the domain name in the configuration files; if not, the next domain name in the configuration file is continuously traversed. If all the domain names in the configuration file are different from the domain name accessed by the client, the DNS cannot analyze the domain name accessed by the client, and the execution is finished.
2. If the sub-domain name resolution function is not started, the priority of the sub-domain name does not need to be judged:
traversing all domain names in the configuration file, directly comparing the domain names in the configuration file with domain names accessed by the client, judging whether the domain names are the same or not, and if the domain names are the same, returning the position of the domain name in the configuration file; if not, the next domain name in the configuration file is continuously traversed. If all the domain names in the configuration file are different from the domain name accessed by the client, the DNS cannot analyze the domain name accessed by the client, and the execution is finished. If the same domain name is found in the configuration file, the DNS performs calculation according to parameters and strategies under the domain name, and returns a virtual ip of the address pool under the domain name to the client.
According to the coordination method for the load balancing access domain names, the priorities of the normal domain names and the sub-domain names are set in the domain name configuration file, the load balancing rules of the normal domain names and the sub-domain names are configured, and when a subsequent request of a client is subjected to domain name resolution, the load balancing rules are selected according to the resolved domain name information and the preset domain name priorities, so that the problems of system confusion and client request blocking caused by load balancing conflicts of the normal domain names and the sub-domain names are effectively avoided. The embodiment further supplements and perfects the load balancing strategy, and the method can fully consider the requirements of client services, so that the user can correctly access the domain name and expand the requirements of domain name access. By the method, the efficiency of processing the client request by the back-end server can be improved, the network data processing capacity is further enhanced, and the flexibility and the usability of the network are improved.
