Linux Network services -NFS Shared Services I. introduction to NFSPort number: TCP,UDP 111 PortsTheNFSNetwork File system, a Network File system protocol based on TCP/IP transmission, was originally Company Development. By using the NFS protocol, clients can access shared resources on a remote server as if they were accessing a local directory. NFS does not have a user authentication mechanism, and the data is transmitted in clear text on the network, so the security is very poor, generally c

connection server for the Linux kernel upgrade, it is not possible to start the server.⑤, yum Uninstall Package: Yum-y Remove Package NameNote: Uninstall and upgrade are also the same, and since many of the packages have dependencies, you uninstall a, and B and C all depend on a, then both B and C are unloaded. If C and Linux a system software is dependent, and C also unloaded, may cause a system function can not be used. So we must be careful when uninstalling the software.4. Yum Software Grou

Spring Cloud has a pre-processor that decrypts property values locally Environment . It follows the same rules as the Config server, and by encrypt.* having the same external configuration. Therefore, you can use {cipher}* encrypted values in a format that, as long as there is a valid key, will be decrypted before the main application context gets fetched Environment . To use the encryption feature in your application, you need to include Spring security RSA (MAVEN coordinated "Org.springframewo

first-order predicate logic and set theory. Rigorous mathematical theory is used to produce concise, precise, unambiguous and provable specifications. The main feature of the Z language is that the Z specification can be inferred and proven. Enables software developers or users to quickly identify inconsistencies, incomplete specifications, and provide confidence in the software.The key idea of calling Z language a specification language is to separate the requirements Specification phase and t

) { System.out.println ("True"); } The implementation of conditional compilation In the Java language is also a syntax sugar for the Java language, and depending on the true and False Boolean constants, the compiler will eliminate the blocks of code that are not in the branch, which will be done in the compiler's contact with the syntactic sugar phase. Because the implementation of this conditional compilation uses the IF statement, it must follow the most basic Java syntax
