, and other servers will not be able to provide services. of course, you can also consider the title of bidirectional synchronization. 　　3. using NFS to share Session data This plan is similar to the following Mysql plan, but the storage method is different. Generally, a public Network File Server is used as a shared Server. when all Web servers log on, session data is written to this Server, all session data is actually retained on this NFS server. no matter the user visits the too-Web server,
