1. 在root模式下修改内核参数
#vi /etc/sysctl.conf
在代码结尾添加如下代码:
fs.file-max = 6815744
kernel.shmmni = 4096
kernel.shmmax = 4294967295 #物理内存一半
kernel.sem=250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 10488576
fs.aio-max-nr = 10488576
保存并退出
#/sbin/sysctl –p 使修改生效
2. 为oracle用户设置shell限制
#vi /etc/security/limits.conf
在文件尾部添加下列代码:
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle - nofile 1006154
保存退出
3. 在root模式下创建oracle用户和组
#groupadd oinstall
#groupadd dba
#groupadd oper
#useradd –g oinstall –G dba,oper oracle //增加了oracle用户
#passwd oracle (在下面出现的命令行中设置oracle账户口令)
4. 为安装oracle建立目录
#cd /home/oracle //转到oracle目录下
#mkdir app //建立app目录
#chown –R oracle:oinstall /home/oracle/app
#chmod –R 775 /home/oracle/app //赋予权限
5. 切换到oracle账户并为oracle用户设置环境变量
#su – oracle
$vi /home/oracle/.bash_profile
在文件中添加:
export ORACLE_BASE=/home/oracle/app
export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1
export ORACLE_SID=orcl (自己定义的名称)
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export NLS_LANG="SIMPLIFIED CHINESE_CHINA".ZHS16GBK
保存退出
$source /home/oracle/.bash_profile 使其生效
6.重新启动操作系统:
# reboot (重新启动命令)
特别说明:因为安装Oracle软件时不可使用root(超级用户)来进行安装,只可以使用刚才新建的oracle用户来进行安装,请大家一定要注意!
7.通过FTP工具把oracle11g压缩包复制到oracle文件夹下面
8.在oracle模式下解压oracle11g压缩包
#unzip linux.x64_11gR2_database_1of2.zip –d /home/oracle
#unzip linux.x64_11gR2_database_2of2.zip –d /home/oracle
9.新开一个终端窗口,以root身份执行命令 #xhost +
10.然后回到oracle窗口
进入database目录
$cd /home/oracle/database
$./runInstaller
开始安装。剩下的安装步骤和在windows下一样。
到最后千万要执行最后两个命令。

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.
