mysql关系型数据库设计和优化

一. 表的设计满足3NF

1. 最高范式为6NF,只能在满足1NF的情况才能满足2NF,以此类推;

2.  1NF是表的属性(列)具有原子性,表的列不能再分,且不能有重复的列,只要是关系型数据库就满足1NF;

3.  2NF 是指表中不能有完全重复的记录(行),通过设置主键规避2NF;

4.  3NF 是如果列的内容可以通过已有的列或表推导出来,就不要使用单独的列来存储。

5. 通常情况下,表的设计必须遵循3NF要求,但有时候根据业务的不同可能需要违反3NF的规则,查询效率可能更高,称反3NF;

6. 数据表中含有多个非定长和定长的列时可以把表拆分为2,把定长的数据和非定长的数据分开存放;

7.设计表是字段不能为NULL,可以使用其他的值代替;

8.使用联合索引提高查询效率,

           ALTER TABLE用来创建普通索引、UNIQUE索引或PRIMARY KEY索引:

           ALTER TABLE table_name ADD INDEX index_name (column_list)

           ALTER TABLE table_name ADD UNIQUE (column_list)

ALTER TABLE table_name ADD PRIMARY KEY (column_list)

二. 创建适当的索引

  1. 设置索引sql语句 ‘alter table 表名 add primary key (‘字段名’)’;
  2. 创建完索引后数据库文件中会产生后缀为‘.MYI’结尾的文件,即数据表的索引文件,单个(字段)索引文件大小大约占用表数据的1/5,如下,分别是表结构文件、表数据文件、表索引文件:4
  3. 索引在大表中(1G以上的表数据)使用过多,占用空间较大,在中小型项目中可以使用适当的索引来提高系统的查询时间。

三. 优化数据库

1.先构建海量表,定位慢查询。

构建海量表,且数据不一样,需要创建存储过程完成创建或通过PHP写入随机数据,如下图,构建简单的个人资料表;

1

 

2. 在mysql服务正常开启时,默认不会纪录慢查询,启动慢查询方式如下:

2.1  在mysql命 令行下使用“show variables”查看mysql数据库的变量设置,确定如下慢查询日志已经开启,或可在my.ini中可添加配置:

log_slow_queries=ON   #开启慢查询
long_query_time=1       #设置慢查询记录时间
slow_query_log=ON     #开启日志记录
log_queries_not_using_indexes=ON  #索引字段不记录
slow_query_log_file = h:\wamp\logs\mysql_slow_query.log   #慢查询日志写入文件

2.2 查看纪录慢查询的查询时间最大值“show variables like ‘long_query_time’,设置纪录慢查询的时间命令 set long_query_time=1(配置文件中更改也可.配置后重启数据库服务器);

3

2.3 开启慢查询日志记录和慢查询,设置log_slow_queries=1和slow_query_log=1即可,修改系统变量使用命令:set GLOBAL log_sloe_queries=1(建议在配置文中修改,步骤1);

2.4 配置完成后,mysql就可以记录查询长设置时间的查询了,可以定位到项目中执行较慢的语句并针对优化,至于慢查询的时间设置根据业务需求自行配置.

windows 2008 服务器配置问题

前些天在配置服务器windowns 2008的phpstudy集成环境时,服务器环境安装好了,局域网无法访问的问题,当时也是各种排查,查了几个小时还是没找到问题。

当时的问题是这样的,使用数据库连接工具连不上服务器的数据库(已经配置了mysql的权限),使用局域网的机器ping服务器的IP不通,但是服务器ping局域网ip是可以的,然后就在服务器防火墙入站规则中的一个配置中修改一下参数,然后ping的问题解决了,试着连接还是返回连接不上!

后来查了各种资料,最后在总监的帮助下弄明白了要设置服务器防火墙的入站规则,就单独给mysql设置了端口3306的入站规则,终于连接上数据库了,但网站还是无法访问,一想是不是需要给apache单独配置入站规则?

那就尝试一下吧!按照mysql的协议,配置80端口的入站规则,测试,不行!后面把协议改成任何,测试通过,终于把问题搞定!

小和尚卖石头

640

一天,一个小和尚跑过来,请教禅师:“师父,我人生最大的价值是什么呢?”禅师说:“你到后花园搬一块大石头,拿到菜市场上去卖,假如有人问价,你不要讲话,只伸出两个指头;假如他跟你还价,你不要卖,抱回来,师父告诉你,你人生最大的价值是什么。”

第二天一大早,小和尚抱块大石头,到菜市场上去卖。菜市场上人来人往,人们很好奇,一家庭主妇走了过来,问:“石头多少钱卖呀?”和尚伸出了两个指头,主妇说:“2元钱?”和尚摇摇头,家庭主妇说:“那么是20元?好吧,好吧!我刚好拿回去压酸菜。”小和尚听到:“我的妈呀,一文不值的石头居然有人出20元钱来买!我们山上有的是呢!”

于是,小和尚没有卖,乐呵呵地去见师父:“师父,今天有一个家庭主妇愿意出20元钱,买我的石头。师父,您现在可以告诉我,我人生最大的价值是什么了吗?”禅师说:“嗯,不急,你明天一早,再把这块石头拿到博物馆去,假如有人问价,你依然伸出两个指头;如果他还价,你不要卖,再抱回来,我们再谈。”

第二天早上,在博物馆里,一群好奇的人围观,窃窃私语:“一块普通的石头,有什么价值摆在博物馆里呢?”“既然这块石头摆在博物馆里,那一定有它的价值,只是我们还不知道而已。”这时,有一个人从人群中窜出来,冲着小和尚大声说:“小和尚,你这块石头多少钱卖啊?”小和尚没出声,伸出两个指头,那个人说:“200元?”小和尚摇了摇头,那个人说:“2000元就2000元吧,刚好我要用它雕刻一尊神像。”小和尚听到这里,倒退了一步,非常惊讶!

他依然遵照师傅的嘱托,把这块石头抱回了山上,去见师傅:“师傅,今天有人要出2000元买我这块石头,这回您总要告诉我,我人生最大的价值是什么了吧?”禅师哈哈大笑说:“你明天再把这块石头拿到古董店去卖,照例有人还价,你就把它抱回来。这一次,师傅一定告诉你,你人生最大的价值是什么。”

第三天一早,小和尚又抱着那块大石头来到了古董店,依然有一些人围观,有一些人谈论:“这是什么石头啊?在哪儿出土的呢?是哪个朝代的呀?是做什么用的呢?”终于有一个人过来问价:“小和尚,你这块石头多少钱卖啊?”小和尚依然不声不语,伸出了两个指头。“20000元?”小和尚睁大眼睛,张大嘴巴,惊讶地大叫一声:“啊?!”那位客人以为自己出价太低,气坏了小和尚,立刻纠正说:“不!不!不!我说错了,我是要给你200000元!” “200000元!”小和尚听到这里,立刻抱起石头,飞奔回山上去见师父,气喘吁吁地说:“师父,师父,这下我们可发达了,今天的施主出价200000元买我们的石头!现在您总可以告诉我,我人生最大的价值是什么了吧?”

禅师摸摸小和尚的头,慈爱地说:“孩子啊,你人生最大的价值就好像这块石头,如果你把自己摆在菜市场上,你就只值20元钱;如果你把自己摆在博物馆里,你就值2000元;如果你把自己摆在古董店里,你值200000元!平台不同,定位不同,人生的价值就会截然不同!”

这个故事是否启发了你对自己人生的思考?你将如何定位自己的人生呢?你准备把自己摆在怎样的人生拍卖场去拍卖呢?你要为自己寻找一个怎样的人生舞台呢?

不怕别人看不起你,就怕你自己看不起自己。谁说你没有价值?除非你把自己当作破石头放在烂泥中,没有人能够给你的人生下任何的定义。你选择怎样的道路,将决定你拥有怎样的人生。

为什么一个老板再难,也不会轻言放弃,而一个员工做得不顺就想逃走,为什么一对夫妻再吵再大矛盾,也不会轻易离婚,而一对情侣常为一些很小的事就分开了。说到底,你在一件事,一段关系上的投入多少,决定你能承受多大的压力,能取得多大的成功,能坚守多长时间。 冯仑说,伟大都是熬出来的。为什么用熬,因为普通人承受不了的委屈你得承受,普通人需要别人理解安慰鼓励,但你没有,普通人用对抗消极指责来发泄情绪,但你必须看到爱和光,在任何事情上学会转化消化,普通人需要一个肩膀在脆弱的时候靠一靠,而你就是别人依靠的肩膀。 孝庄对康熙说:孙儿,大清国最大的危机不是外面的千军万马,最大的危难,在你自己的内心。

弟子问:师父您有时候打人骂人,有时又对人又彬彬有礼,这里面有什么玄机吗?师父说:对待上等人直指人心,可打可骂,以真面目待他;对待中等人最多隐喻他,要讲分寸,他受不了打骂;对待下等人要面带微笑,双手合十,他很脆弱、心眼小,只配用世俗的礼节对他!你受得了何种委屈,决定你能成为何种人。

一个不会游泳的人,老换游泳池是不能解决问题的;

一个不会做事的人,老换工作是解决不了自己的能力的;

一个不懂经营爱情的人,老换男女朋友是解决不了问题的;

一个不懂经营家庭的人,怎么换爱人都解决不了问题;

一个不学习的老板,绝对不会持续的成功。

我是一切的根源,要想改变一切,首先要改变自己!学习是改变自己的根本。其实,你爱的是你自己;你喜欢的亦是你自己。你爱的、你恨的,都是你自己。你变了,一切就都变了。

你的世界是由你创造出来的;

你的一切都是你创造出来的;

你是阳光,你的世界充满阳光;

你是爱,你就生活在爱的氛围里;

你是快乐,你就是在笑声里。

同样的,你每天抱怨、挑剔、指责、怨恨,你就生活在地狱里;一念到天堂,一念下地狱。你心在哪,成就就在哪!

为什么你的公司被干掉了?

哲学界George Santayana曾经说过,“那些不懂得从过去学习经验的人注定要在同样的石头上摔第二次。”创业是一个不断试错的过程,失败则是一个排除的过程。在浩浩荡荡的创业大潮中,失败者远比成功者更多,总结前人之过,对于创业者来说,也许更有用。

2015年,中国每分钟诞生8家公司,平均每天新登记注册的企业达到1.16万户。然而,这些企业的平均寿命却不足3年,中国创业企业的失败率为80%左右,每年新创办的企业中有50%会在半年内倒闭。

都说创业改变命运,可是你看,如果方法不对,不要说改变了,可能连”命”都保不住!

致命方法一:招聘员工,”能力”放首位。

当你在积极为企业选拔有能力的员工时,成功的创业者早已懂得招聘价值认同度高的员工。工作能力也许可以提高工作效率,而员工对企业价值的共识才能推动企业源源不断的向前发展。

致命方法二:低估了创业的艰难

当你单纯的认为创业有两条路(成功的路与失败的路)可以走时,成功的创业者早就知道了创业没有所谓的顺境,成功没有捷径可言,做好了完全失败的准备。

致命方法三:固步自封

当你紧紧抓着目前的赢利点沾沾自喜,舍不得放手时,成功的创业者早已另辟蹊径,尝试起新鲜的事物,获取更大的盈利空间。

致命方法四:弱者心态

当你为缺钱苦不堪言,有了打算放弃创业的念头时,成功的创业者早就树立了”没钱更要创业”的心态。创业,亦是一场心态的比拼。

致命方法五:乐忠于融资

当你费尽心思,想要拿到尽量多的融资时,成功的创业者早就想尽办法,让项目变得具有价值,有价值的项目自然可以赢得市场。

致命方法六:脑子里只想着赢

当你把心思全部放在如何打败竞争对手上时,成功的创业者已经开始考虑公司是否具有垄断项目,企业是否可以独特长久的存在。当你把目标致力于我要变得更强时,成功的创业者思考的不仅是变强还有企业的吸引力、知名度等问题。

致命方法七:眼光狭隘

当你在思考如何吸引优秀人才时,成功的创业者已经在培养人才!当你在思考公司如好更好的发展时,成功的创业者已经在思考企业应该怎样存在!当你在苦苦寻觅最厉害的管理者时,成功的创业者已经不再刻意管理,而是让管理归于简单。当你还在思考未来如何发展时,成功的创业者已经开始调整发展战略,不思考未来,而是思考未来需要怎样的企业。

致命方法八:只搞老一套

当你在为产品营销寻觅推广高手时,成功的创业者已经在改善产品,使其更具吸引力。当你还在用口号、奖励、活动来激励员工时,成功的创业者已经在靠企业文化、企业格调来吸引员工。当你还在死守着”资金”、”人脉”、”市场”、”竞争力”这些元素时,成功的创业者已经开始探讨企业价值。当你还在乐此不疲的做热门领域时,成功的创业者已经成功开辟了小而新的领域,不走寻常道。

致命方法九:没有主心骨

当你已被投资人套牢,被他们牵着鼻子走时,成功的创业者早已明确了目标,凡事自己拿主意。当你还在模棱两可,无法对公司进行清晰定位时,成功的创业者早就有了明确的定位,永远知道下一步怎么走。

致命方法十:过于追求完美

当你事无巨细都想尽善尽美时,成功的创业者早就成功锁定目标,从用户角度设计产品,制定销售策略,把力放在一处使。

致命方法十一:盲目创新

当你大胆尝试,进行颠覆式创新时,成功的创业者早就懂得适度改变才是最好的创新,完全颠覆,只能是一次没有结果的冒险。

致命方法十二:小心翼翼

当你还在谨慎小心,担心犯错,不敢迈出步子时,成功的创业者早就懂得了稳中求变。变则通,不变只能等死。

我知道,大多数人都喜欢讨论成功,而极少数愿意谈及失败。就像是野兽总是不想将伤口暴露在外面。然而,探讨失败的意义,可能远远大于成功。因为只有面对挫折,总结教训,企业才能往前走!
