三四年没有安装过mysql+apache+PHP的环境了,我以前是做银行性能测试外包服务的,在甲方开发中心遇到这样环境的项目也比较少,大多是WebLogic/WebSphere+Oracle/DB2架构的大型系统。涉足电商行业方面的项目,不得不再去温故那些几乎遗忘的IIS、apache、MSsql、mysql等环境。

平台:VMware上虚拟的centos4.7

宿主机:windows

安装mysql前准备:

1、检查该环境中是否已安装mysql,检查方法:netstat –ano命令查看mysql默认端口3306是否存在;或者再命令行中执行mysql

2、下载mysql安装包

在http://www.mysql.com/downloads/mysql/#downloads下载mysql安装包:

MySQL-server-5.5.28-1.linux2.6.i386.rpm

MySQL-client-5.5.28-1.linux2.6.i386.rpm

使用rpm –ivh命令来安装mysql,这里不说啦。

先来了解一下mysql数据库默认的一些主要目录:

1、数据库目录 /var/lib/mysql/

2、配置文件  /usr/share/mysql(mysql.server命令及配置文件)

3、相关命令  /usr/bin (mysqladmin mysqldump等命令)

4、启动脚本  /etc/rc.d/init.d/(启动脚本文件mysql的目录)

安装后通过netstat –ano命令查看mysql默认端口3306是否存在,如果不存在,按下面的方法启动mysql服务。

启动mysql服务:

[root@localhostmysql]# pwd/usr/share/mysql[root@localhostmysql]# ./mysql.server startStartingMySQL...[  确定  ][root@localhostmysql]# netstat -anoActiveInternet connections (servers and established)ProtoRecv-Q Send-Q Local Address              Foreign Address            State       Timertcp        0     0 0.0.0.0:3306               0.0.0.0:*                   LISTEN      off (0.00/0/0)[root@localhostmysql]# mysqlWelcometo the MySQL monitor.

Type '/c' to clear the current input statement.mysql>mysql>

启动与停止

1、启动
  MySQL安装完成后启动文件mysql在/etc/init.d目录下,在需要启动时运行下面命令即可。  

[root@localhost mysql]#  /etc/init.d/mysql start

2、停止  

[root@localhost mysql] #  /usr/bin/mysqladmin -u root -p shutdown

3、自动启动

  1)察看mysql是否在自动启动列表中  

[root@localhost mysql] # /sbin/chkconfig –list

  2)把MySQL添加到你系统的启动服务组里面去  

[root@localhost mysql] # /sbin/chkconfig – add mysql

  3)把MySQL从启动服务组里面删除。 

[root@localhost mysql] # /sbin/chkconfig – del mysql

oracle asm指的是“自动存储管理”,是一种卷管理器,可自动管理磁盘组并提供有效的数据冗余功能;它是做为单独的Oracle实例实施和部署。asm的优势:1、配置简单、可最大化推动数据库合并的存储资源利用;2、支持BIGFILE文件等。

oracle全角怎么转半角oracle全角怎么转半角May 13, 2022 pm 03:21 PM

在oracle中,可以利用“TO_SINGLE_BYTE(String)”将全角转换为半角;“TO_SINGLE_BYTE”函数可以将参数中所有多字节字符都替换为等价的单字节字符,只有当数据库字符集同时包含多字节和单字节字符的时候有效。

Oracle怎么查询端口号Oracle怎么查询端口号May 13, 2022 am 10:10 AM

在Oracle中,可利用lsnrctl命令查询端口号,该命令是Oracle的监听命令;在启动、关闭或重启oracle监听器之前可使用该命令检查oracle监听器的状态,语法为“lsnrctl status”,结果PORT后的内容就是端口号。

oracle查询怎么不区分大小写oracle查询怎么不区分大小写May 10, 2022 pm 05:45 PM

方法:1、利用“LOWER(字段值)”将字段转为小写,或者利用“UPPER(字段值)”将字段转为大写;2、利用“REGEXP_LIKE(字符串,正则表达式,'i')”,当参数设置为“i”时,说明进行匹配不区分大小写。

oracle怎么删除sequenceoracle怎么删除sequenceMay 13, 2022 pm 03:35 PM

在oracle中,可以利用“drop sequence sequence名”来删除sequence;sequence是自动增加数字序列的意思,也就是序列号,序列号自动增加不能重置,因此需要利用drop sequence语句来删除序列。

oracle怎么查询数据类型oracle怎么查询数据类型May 13, 2022 pm 04:19 PM

在oracle中,可以利用“select ... From all_tab_columns where table_name=upper('表名') AND owner=upper('数据库登录用户名');”语句查询数据库表的数据类型。

Oracle怎么修改sessionOracle怎么修改sessionMay 13, 2022 pm 05:06 PM

方法:1、利用“alter system set sessions=修改后的数值 scope=spfile”语句修改session参数;2、修改参数之后利用“shutdown immediate – startup”语句重启服务器即可生效。
