CentOS 5.5上安装Oracle 11g R2最完全安装教程
一:准备条件
1、CentOS的准备。
首先,什么最重要:分区最重要。显然,分区越大越好,尤其是SWAP空间要大一点,至少2G。
其次,对于新手,有两点需要注意。第一,安装软件时最好完全按照;第二,把防火墙、SElinux等都去掉,才能顺利安装。
2、基础准备
首先,准备软件:
linux_11gR2_database_1of2.zip
linux_11gR2_database_2of2.zip
其次,准备两个工具:
FileZilla_3.3.3_win32-setup.exe
Putty
其中,FileZilla可以把一些文件等传输到虚拟机里面,很方便;Putty是一个远程登录工具,可以方便的登录到虚拟机CentOS里面。
准备情况结束。
二:安装Oracle前的准备。
1、系统安装额外软件:
yum -y install binutils compat-libstdc++-33elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gccgcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstatunixODBC unixODBC-devel pdksh numactl-devel glibc-headers
/sbin/ldconfig
2、调整内核参数
首先
vi /etc/sysctl.conf
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
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 = 1048576
fs.aio-max-nr = 1048576
#让内核参数生效
sysctl -p
其次,
#修改limits.conf
vi /etc/security/limits.conf
#oracle settings
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
然后:
#修改系统版本(RedHat 5.×系列系统略过这步)
cp /etc/redhat-release/etc/redhat-release.bk
vi /etc/redhat-release
#修改内容为:
Red Hat Enterprise Linux AS release 5(Taroon)
#修改/etc/pam.d/login
#添加以下内容:
session required /lib/security/pam_limits.so
session required pam_limits.so
最后:
#修改/etc/profile
vi /etc/profile
#添加以下内容:
if [ $USER = "oracle" ]; then
if[ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
#修改/etc/csh.login
vi /etc/csh.login
#添加以下内容:
if ( $USER == "oracle" ) then
limit maxproc 16384
limit deors 65536
endif
3、创建ORACLE用户
首先
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
passwd oracle #753951
mkdir -p /data/oracle
mkdir -p /data/oralnventory
mkdir -p /data/software
chown -R oracle:oinstall /data/oracle
chown -R oracle:oinstall /data/software
chown -R oracle:oinstall /data/oralnventory
然后,设置环境变量
#su - oracle
$ vi .bash_profile
#添加以下内容:
ORACLE_SID=kerry; export ORACLE_SID
ORACLE_BASE=/data/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1;export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin;export PATH
$source .bash_profile
注:最好把主机的地址添加到/etc/hosts里面:
[root@localhost /]# cat /etc/hosts
# Do not remove the following line, or variousprograms
# that require network functionality willfail.
127.0.0.1 localhost.localdomain localhost
192.168.1.103 localhost.localdomain localhost
#::1 localhost6.localdomain6 localhost6
4、即将安装
上传文件
#上传oracle安装文件到/data/software目录下,并解压
cd /data/software
unzip linux_11gR2_database_1of2.zip
unzip linux_11gR2_database_2of2.zip
然后,
xhost local:oracle (这里使用root用户执行,一定要执行以下2步,如果没有执行,,将无法启动图形安装界面)

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.

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 is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

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.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

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
