MYSQL网站制作之公布MySQL集群主动安装剧本1.0！

如果互联网服务提供商，支撑数据的云服务，或它们之间任一点网络被堵塞或中断，他们就会遇到与数据延迟或应用程序故障有关的问题。如果问题发生在企业内部，解决方案提供商可以排除故障找出原因。mysql|剧本|主动安装经由几天的测试，终究能够公布了！

1.在MySQL源代码目次下新建剧本install.sh，把上面的代码增加到这个剧本中：

2.设置剧本权限，让它可实行：chmod755install.sh
3.实行该剧本：./install.sh大概./install<MySQL安装目次>

详细利用申明，英语好的看剧本正文吧；英语欠好的，那就再等等，过几天会release出来。应用程序需要使用数据库，数据库本身需要设计、开发和部署。还有MySQL学习教程，客户怎样实施混合系统，或者需要帮助管理多个云服务?

作了些试验，发现使用CLR的存储过程或函数在达到一定的阀值的时候，系统性能会呈指数级下滑！这是非常危险的！只使用几个可能没有问题，当一旦大规模使用会造成严重的系统性能问题！

财务软件要用SQL也只是后台的数据库而已,软件都是成品的,当然多学东西肯定是有好处的..

大家注意一点。如下面的例子：

学习SQL语言的话如果要学会去做网站就不是很难!但是要做数据库管理的话就有难度了!

索引视图2k就有。但是2005对其效率作了一些改进但是schema.viewname的作用域真是太限制了它的应用面。还有一大堆的环境参数和种种限制都让人对它有点却步。

如果我们从集合论（关系代数）的角度来看，一张数据库的表就是一组数据元的关系，而每个SQL语句会改变一种或数种关系，从而产生出新的数据元的关系（即产生新的表）。
