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)

linux

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

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.
