To better explain the offline authorization system, please refer to fig. 3, where fig. 3 is a schematic structural diagram of an offline authorization system according to an embodiment of the present invention, including: a first server 301 and a second server 302.
The first server 301 is configured to obtain an authorization request sent by the second server 302, and send a license certificate to the second server 302 according to the authorization request.
In a specific embodiment, the first server 301 is configured to obtain an authorization request sent by the second server 302, and send a license certificate to the second server 302 according to the authorization request, specifically:
the first server 301 comprises a master authorization server and a plurality of slave authorization servers;
when the master authorization server does not work normally, selecting one of the slave authorization servers which work normally as a new master authorization server, so that a first module in the new master authorization server acquires an authorization request sent by a second module in the second server 302 and sends a license certificate to the second module in the second server 302 according to the authorization request;
when the master authorization server works normally, the first module in the master authorization server directly obtains the authorization request sent by the second module in the second server 302, and sends a license to the second module in the second server 302 according to the authorization request.
The second server 302 is configured to perform offline authorization according to the license certificate after receiving the license certificate, and obtain a right corresponding to the authorized content in the license certificate when the offline authorization is successful.
In one embodiment, the second server 302 is a server added to a server cluster by the first server 301.
Specifically, the first server 301 deploys a basic service, where the basic service includes: SQL and Redis services ensure the intercommunication of Web and signaling; the second server 302 deploys a media service, which includes: MCU medium.
Specifically, if the Redis master-slave mode is adopted, the number of the first servers 301 needs to be an odd number to achieve high availability; if other architectures are adopted, the number of the first servers 301 may be greater than or equal to 2.
From the above, the first module is configured to perform a license management service, and specifically: obtains the authorization request and sends a license credential to the second server 302 based on the authorization request. Since the license certificate includes the authorized content, the second server 302 can obtain the right corresponding to the authorized content after performing offline authorization according to the license certificate and successful authorization. The second module is used for performing license agency service, and specifically includes: and receiving the license certificate, performing offline authorization according to the license certificate, and obtaining the right corresponding to the authorized content in the license certificate when the offline authorization is successful.
The second module can also enable a second server where the second module is located to be offline after receiving the offline instruction of the first module; and reporting the device information to the first module.
The information synchronization between the first module and the second module, the first module can acquire all first machine code information in a second server which has joined the server cluster, if a user replaces any one server in the server cluster with a strange server, the first module acquires the strange first machine code information, and the strange first machine code information cannot be matched with the second machine code information stored in the first module, the first module issues a logout instruction to the strange server, so that the strange server is offline and leaves the server cluster. The condition that a user privately adds an unfamiliar server into the server cluster to increase the conference concurrency capability can be effectively avoided.
In addition, the second module knows the IP information of the plurality of first servers, and may select one of the first servers to report the information by default, or may hash the IP information and report the IP information to the plurality of first servers. And information between the plurality of first servers is synchronized.
To further illustrate that the offline authorization system ensures high availability of license offline authorization activation, please refer to fig. 4 and 5, and fig. 4 and 5 are schematic diagrams illustrating failure of the first server and failure of the second server according to an embodiment of the present invention.
Wherein, 1-1, 1-2 and 1-3 in fig. 4 and 5 are all first servers, and a1, a2 and A3 are all first modules in the first servers; 2-1, 2-2, 2-3 and 2-4 are all second servers, and B1, B2, B3 and B4 are all second modules in the second servers. 1-1 is a master authorization server in the first server, and 1-2 and 1-3 are slave authorization servers in the first server.
As can be seen from fig. 4, when the master authorization server 1-1 fails to operate normally and fails, then B1, B2, B3 and B4 cannot keep alive communication with a 1. The second servers 2-1, 2-2, 2-3 and 2-4 select 1-2 from the normally operating slave authorization servers 1-2 and 1-3 as the new master authorization server so that a2 in 1-2 starts to dominate the entire license management service. Since the information between a1, a2, and A3 is synchronized, it is quickly possible to set 1-2 as the new master authorization server. After 1-2 is set as a new master authorization server, B1, B2, B3 and B4 report the device to A2 for offline authorization or keep alive communication after offline authorization is successful and A2.
As can be taken from fig. 5, when one of the plurality of second servers fails, such as 2-1 fails, the master authorization server 1-1 considers 2-1 offline. If a conference is required, the master authorisation server 1-1 does not schedule media to 2-1 but to 2-2, 2-3 and 2-4. After scheduling, no influence is caused on license management service, and the conference is normally opened; if the 2-1 fails while the conference is in progress, the conference is interrupted.
When the master authorization server does not work normally, one slave authorization server which works normally is selected as a new master authorization server and sends an authorization request, so that the new master authorization server sends a license certificate according to the authorization request; the master authorization server and the slave authorization server carry out keep-alive communication through an intranet; and receiving the license certificate, and performing offline authorization according to the license certificate. By adopting the embodiment of the invention, when the master authorization server can not work normally, one of the plurality of slave authorization servers which work normally is selected as the new master authorization server to ensure the normal operation of the off-line authorization work, thereby avoiding the problems of paralysis and failure of authorization work caused by the failure of only one server for authorization and effectively improving the success rate of the off-line authorization; meanwhile, after the license certificate determines a new main authorization server, the license certificate can smoothly reach the equipment needing authorization, so that the equipment can be successfully authorized according to the license certificate, and high availability of off-line authorization activation of the license certificate is ensured.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
