win7x64安装配置Oracle 11g R2数据库

安装前的准备

Oracle数据库安装文件,下载地址见Oracle官网:https://www.oracle.com/

开始安装

1、Oracle11gR2的安装文件分成了两个,需要我们在解压的时候,解压到相同的目录下边,里面文件的目录名是默认的database,如图所示:

2、解压到相同目录之后,双击文件夹中的setup.exe文件,双击之后,出现启动安装界面的命令窗口,会检查监视器配置,并且启动安装界面进入正式安装界面,如图所示,取消下图所示的选中,即不接受安全更新,然后单击"下一步"继续,会提示尚未提供电子邮件,不管,直接点是,Oracle默认是选择基本安装。

Linux进程管理

进程的概念

Linux系统中进程的类型

分为三种不同的类型,分别是:

  • 交互进程:由一个启动的进程,交互进程既可以在前台运行,也可以后台运行。

  • 批处理进程:不与特定的终端相关联,提交到等待队列中顺序执行的进程。

  • 守护进程:在Linux在启动时初始化,需要时运行于后台的进程。

进程的启动方式

手工启动:1、前台启动  2、后台启动

调度启动:事先进行设置,根据用户要求自行启动

Linux网络配置和管理

网络设备信息查看和配置

文件配置

在CentOS中,系统网络设备的配置文件保存在“/etc/sysconfig/network-scripts”目录下,ifcfg-eth0包含第一块网卡的配置信息,ifcfg-eth1包含第二块网卡的配置信息。

vi /etc/sysconfig/network-scripts/ifcfg-eth0

可以得到配置信息

DEVICE=eth0
HWADDR=00:0C:29:35:50:5B
TYPE=Ethernet
UUID=e9e3400b-1e20-49c1-a12c-de3b6b221048
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.118.10
NETMASK=255.255.255.0
NETWORK=192.168.118.0
BROADCAST=192.168.118.255

若希望手工修改网络地址,可以通过修改对应的文件(ifcfg-ethN)或创建新的文件来实现。

具体对应修改方法参见我的csdn博客:CentOS6.7配置静态IP

Linux的文件和文件系统的管理


文件权限

什么是文件系统?

文件系统是操作系统在分区上保存文件信息的方法和数据结构。

文件有哪些权限?

文件有那些权限

三种基本权限分别为:读、写、执行,说明如下:

代表字符 权限 对文件的意义 对目录的意义
r 读权限 可以读文件内容 可以列出目录中的文件列表
w 写权限 可以修改和删除文件 可以在目录中创建和删除文件
x 执行权限 可以执行该文件 可以使用cd命令进入该目录
  1. 目录上只有执行权限,便是可以进入或穿越他进入更深层次的子目录
  2. 目录上只有执行权限,要访问该目录下的又读权限的文件,必须知道文件名才可以访问
  3. 目录上只有执行权限,不能列出目录列表也不能删除该目录
  4. 目录上执行权限和读权限,表示可以进入目录并且列出目录列表
  5. 目录上执行权限和写权限的组合,表示可以在目录中创建、删除和重命名文件

特殊权限

有三种特殊权限suid、sgid和sticky bit。参见Linux中的文件特殊权限

Sublime Text 3解决中文乱码

众所周知,Sublime Text 3(下面简称ST3)的默认编码是utf-8,因此需要把GB2312和GBK编码转换成utf-8。在Sublime Text 2中大家解决中文乱码的方法都是先装好Package Control,然后再通过这个安装ConvertToUTF8的Package。

vi模式转换

经常使用的三种基本模式:命令模式(Command Mode),输入模式(Input Mode),末行模式(Last Line Mode),其他的9种模式不做介绍,很少会使用。

三种基本模式的相互转换如下图:

Linux用户和组管理


概述

只有root用户才能管理用户和组,所以一切命令都是root执行。

用户分类

  1. 超级用户:root,UID=0

  2. 普通用户:具有操作系统有限的权限,500<=UID<=65535(2^32-1),有限个

  3. 伪用户:为了安全,1<=UID<=499

    伪用户解释:linux中任何一个命令的操作都必须有一个用户的身份。伪用户一般和系统或者程序服务相关,比如bin,daemon,shutdown ,halt等,linux默认都有这些伪用户,伪用户通常不需要或无法登陆系统(nologin),可以没有宿主目录
