Oracle数据库安装图解和基本命令行的使用
一、Oracle数据库安装
1. 下载oracle数据库软件
2. 解压win32_11gR1_database.Zip安装包,如图1所示:
图 1
3. 点击setup.exe,选择安装,进入以下图2
图 2
4. 如果上面一步不能跳转到图3,那么需要先关闭安装软件,然后关闭电脑的防火墙,再继续安装。
图 3
这里选择默认安装路径,全局数据库名为:orcl
数据库口令为:intlgj
5. 点击下一步,如果出现图4的情况,点击4,或先删除安装目录下的所有的文件,,再点击选择“是”,进入下一步:
图 4
这些先决条件不用管,继续进入下一步图6 图6 点击“安装”就进入安装程序阶段 图 7 6. 安装 成功 后,还要进行解锁,如图8 图8 系统管理员:sys supermanager 普通管理员:system manager 用户:scott intlgj 7. 安
这些先决条件不用管,继续进入下一步图6
图6
点击“安装”就进入安装程序阶段
图 7
6. 安装成功后,还要进行解锁,如图8
图8
系统管理员:sys supermanager
普通管理员:system manager
用户:scott intlgj
7. 安装成功
图 9
8. 完成之后,直接选择“退出”即可,此时,会启动一个EM(企业管理器)的工具,但在学习中基本没使用这种前台,所以直接关闭即可。
Oracle安装成功后实际会在系统中进行服务的注册,在注册服务中,以下两个服务必须要启动,否则Oracle无法正常运行。
图 10
OracleOraDb11g_home1TNSListener:表示监听服务,如果客户端要连接数据库,此服务必须打开,在日后的开发程序中此服务起作用。
OracleServiceORCL:此服务为Oracle 的主服务,命名规则:OracleService+数据库名称;
之后可以通过命令行方式进入SQLPlus的控制中心,进行命令的输入。
二、Oracle数据库的基本命令行的使用
2.1. SQLPlus
SQLPlus是Oracle提供的一个命令执行的工具软件,安装后会自动在系统中注进行注册。
SQLplus有两种命令:
.sqlplus以命令行方式进入数据库连接,如图11:
图 11
. sqlplusw:以窗口形式启动命令行工具:不过Oracle 11g没有提供该服务。
连接数据库以后,我们就可以进行查询等操作:
在数据库中存在多张表,每张表都有记录:
现在输入以下的命令:
SELECT * FROM EMP;
图 12
原本一行显示的数据二没有按照一行显示,所以显示的格式有点混乱,这就需要我们设置每一行的显示的长度:
设置显示每一行的长度:
Set linesize 300
图13
设置显示每一页的显示的行数:
Set pagesize 30

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
