HomeDatabaseMysql Tutorial在NetWare上搭建MySQL数据库_MySQL

NetWare

    在NetWare服务器上运行MySQL数据库同在Linux、UNIX或Windows系统上运行是相同的。 NetWare作为文件和打印服务器操作系统已经久负盛名,它同样还是一个搭建网络数据库的平台。Microsoft SQL Server及Oracle使得Windows NT/2000获得了更广泛的认可,但在NetWare上同样能够运行SQL数据库。Novell通常将Oracle引入到Netware中,最近又提供了对流行的开放源代码数据库MySQL的支持。

  什么是MySQL?

  MySQL是一种支持SQL数据库语言的开放源代码数据库。MySQL按照GPL许可使用,这意味着只要不开发和出售基于MySQL的应用程序,你就可以免费使用MySQL。然而,如果你想出售基于MySQL的应用程序,则可以购买商用许可。

  像绝大多数的SQL数据库一样,MySQL的语法同Oracle或微软SQL Sever所使用的SQL稍有不同。这样的差异就类似于美语、澳大利亚语和英语的差异。MySQL变化不大的是对操作系统的支持。由于它是开放源代码的, MySQL已经被移植到了多种不同的操作系统上。MySQL支持如下操作系统,不同于Netware,如:

  Windows

  Linux

  Solaris

  FreeBSD

  Mac OS X

  出于本文目的,我将会讨论MySQL 4.013,该版本是现在MySQL企业环境中针对所有操作系统的版本。MySQL 4.1以及MySQL 5.0现在分别处于beta和alpha测试阶段。但现在还没有NetWare的相关测试版本。在企业中,无论如何你都不会希望运行测试版。因此这并不是个问题。

  获取MySQL及安装准备

  你可以从MySQL的下载页面获取MySQL for Netware。你必须在下载软件前填写一份表格,然后你将会被链至一个下载镜像页面,你可以从中选择一个站点来下载MySQL。你下载的文件(在本文发布时,该文件为mysql-standard-4.0.13-pc-netware-i686.zip)只有5.7 MB。因此下载过程不需要花很多时间。

  将文件提取到服务器上的临时目录,但先不要立即安装。首先,你必须确保你的Netware服务器已经为运行MySQL做好了准备。根据文档,MySQL只能运行在NetWare 6及更新版本上,因此如果你运行的是NetWare 4.x 或5.x,那么你似乎不那么幸运。我在自己的NetWare 5.1测试服务器上使用MySQL的确还没有遇到任何问题。然而,应当注意由于NetWare 5.1未被获得官方支持,你可能不应将其应用到企业环境。

  此外,你还必须在NetWare 6上运行Support Pack 2或更新的升级包,以及最新的C Libraries for NetWare。最终,你必须在NetWare服务器上拥有一份NSS卷标以支持MySQL的数据目录。

  安装LibC

  C Libraries即Novellspeak中的LibC,提供了对NetWare多线程以及多处理器应用的支持。如果你之前从未在NetWare服务器上使用过任何的第三方软件,你很有可能还没有安装这些软件。因为LibC以及MySQL都处于开发人员的频繁升级中,你应当确定你获取的是最新版本的 LibC以确保其同MySQL兼容。

MySQL's Role: Databases in Web ApplicationsMySQL's Role: Databases in Web ApplicationsApr 17, 2025 am 12:23 AM

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

MySQL: Building Your First DatabaseMySQL: Building Your First DatabaseApr 17, 2025 am 12:22 AM

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL: A Beginner-Friendly Approach to Data StorageMySQL: A Beginner-Friendly Approach to Data StorageApr 17, 2025 am 12:21 AM

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
