Dual-active data center, the usually purpose for calamity standby (Disaster Recovery), build 2 (or multiple)
Data center.One is primary data center for undertaking the business of user, and one is Backup Data center for backing up master data
Data, configuration, the business at center etc..
Session sharing mode:
Session based on NFS is shared.NFS is the abbreviation of Net FileSystem, is earliest to solve by Sun Microsystems
Catalogue sharing between Unix network host and research and develop.The realization of this scheme is the simplest, without doing excessive secondary development, it is only necessary to
By the local session catalogue of share directory server mount to each channel server, the disadvantage is that NFS relies on complexity
Security mechanism and file system, therefore it is concurrent inefficient, particularly with the small documents of this kind of high concurrent read-write of session,
Can be excessively high due to the io-wait of share directory server, finally tie down the execution efficiency of front-end WEB application program.
Session based on database is shared.Preferred certainly famous Mysql database, and suggest using
Memory table Heap improves the read-write efficiency of session operation.The practicability of this scheme is stronger, using universal, it the shortcomings that
It is that the concurrent reading and writing ability of session depends on the performance of Mysql database, while needs oneself to realize that session is eliminated
Logic is easy to appear table lock so that timing updates from tables of data, deletes session record when concurrent excessively high.
Session based on Cookie is shared.Still commonplace in large-scale website to be used.Principle is to use whole station
Family Session information encryption, serializing after in a manner of Cookie, be uniformly planted in rhizosphere under one's name (such as: .host.com),
When accessing all second level domain websites of the rhizosphere under one's name using browser, it can transmit in the corresponding all Cookie of domain name therewith
The characteristic of appearance, to realize share and access of the Cookieization Session of user between more services.The advantages of this scheme, is not necessarily to
Additional server resource；The disadvantage is that can only store the user of fraction due to being limited by http protocol header confidence length
Information, while the Session content of Cookieization needs to carry out safe encryption and decryption (such as: adding solution in plain text using DES, RSA progress
It is close；Anti-fake certificate is carried out by MD5, SHA-1 scheduling algorithm again), certain bandwidth resources are in addition occupied, because browser can request
The current field under one's name any resource when local Cookie be attached in http be transmitted to server.
