S103, for each condition setting, calculating a similarity value between the condition setting at the time of the first client access and the condition setting at the time of the client access for each candidate server.
And aiming at all condition settings of the multi-dimensional sampling samples, listing data of the first client under all condition settings, and comparing each data with the multi-dimensional sampling samples of all clients respectively. A similarity value between the first client and all multi-dimensional sampled samples is determined.
For example, three clients form a matrix array, S, of multidimensional sampling samples under three different conditions of x, y, and z1＝{ep1x，ep1y，ep1z}、S2＝{ep2x，ep2y，ep2z}、S3＝{ep3x，ep3y，ep3zThe data of the first client under the three conditions of x, y and z is A, B, C, where a is equal to ep in the matrix1x，ep2x，ep3xComparing, if an identical item appears, the similarity value under the condition setting 1 is 0.33, and continuing to compare B with ep in the matrix1y，ep2y，ep3yComparing, if two identical terms appear, the similarity value under condition setting y is 0.67, and C is compared with ep in the matrix1z，ep2z，ep3zIn contrast, if three identical terms appear, the similarity value at the condition setting z is 1.
And S104, calculating the total value of each server under a plurality of condition settings according to the similarity value and the corresponding weight value.

Continuing with the example in step S103, let the weights set by the three conditions x, y, and z be px、py、pzThen the total value F of the candidate server1＝px*0.33+py*0.67+pz1, the total value of all candidate servers can be obtained in the same way.
And S105, sending the server with the maximum total value to the first client as an access selection.
The total values of all candidate servers are obtained through step S104, a maximum value is selected from the total values, the server corresponding to the maximum value is used as an access selection to send access notification information to the first client, and the first client receives the access notification information of the server, and then access can be performed.
The embodiment of the invention provides a method for selecting a server to access, which is used for guiding a server to perform similarity calculation with a client which has accessed a candidate server aiming at the characteristics of a first client and relevant condition setting, and selecting the server with the maximum total value under all condition settings.
