Linux下安装Oracle11g

1. 环境：Linux：RedHat Enterprise 5.4 X64 
DB：   Oracle 11g R2 X64


2.检查安装包
 make-3.79.1 
 gcc-3.2.3-34 
 glibc-2.3.2-95.20 
 glibc-devel-2.5-12.i386.rpm 
 glibc-headers-2.5-12.i386.rpm 
 compat-db-4.0.14-5 
 compat-gcc-7.3-2.96.128 
 compat-gcc-c++-7.3-2.96.128 compat-libstdc++-7.3-2.96.128 
 compat-libstdc++-devel-7.3-2.96.128 
 libXpm-3.5.5-3.i386.rpm libXp 
 openmotif21-2.1.30-8 setarch-1.3-1 
 libgomp-4.1.1-52.el5.i386.rpm
 rpm -q gcc make binutils openmotif setarch compat-db compat-gcc               
 compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel libXp 
 由于缺失的包之间有严格的依赖关系，所以必须按照如下顺序安装缺失的包
 rpm -Uvh compat-db-4*
 rpm -Uvh libaio-0*
 rpm -Uvh compat-libstdc++-33-3*
 rpm -Uvh glibc-headers-2.5-12.i386.rpm
 rpm -Uvh glibc-devel-2.5-12.i386.rpm
 rpm -Uvh compat-gcc-34-3*
 rpm -Uvh compat-gcc-34-c++-3*
 rpm -Uvh libXp-1*
 rpm -Uvh openmotif-2*
 rpm -Uvh gcc-4*
 rpm -Uvh glibc-2.5-12.i686.rpm
 rpm -Uvh libgomp-4.1.1-52.el5.i386.rpm
 rpm -Uvh gcc-4.1.1-52.el5.i386.rpm
elfutils-libelf-0.137-3.el5.i386.rpm
elfutils-libelf-0.137-3.el5.x86_64.rpm
elfutils-libelf-devel-0.137-3.el5.i386.rpm
elfutils-libelf-devel-0.137-3.el5.x86_64.rpm
elfutils-libelf-devel-static-0.137-3.el5.i386.rpm
elfutils-libelf-devel-static-0.137-3.el5.x86_64.rpm
elfutils-libelf-devel-0.137-3.el5.x86_64.rpm
elfutils-libelf-devel-static-0.137-3.el5.x86_64.rpm需要同时安装
[root@Dba Server]# rpm -Uvh elfutils-libelf-0.137-3.el5.x86_64.rpm

3.配置内核，编辑/etc/sysctl.conf
添加以下配置
kernel.shmall = 4294967296
kernel.shmall = 4294967296
kernel.shmall = 268435456
kernel.shmall = 2097152 
kernel.shmmax = 5147483648 
kernel.shmmni = 4096 
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 1048576
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr=1048576
注：修改前两项的值，后面的几项是新增加的。
# sysctl -p （是配置立即生效）


4.修改/etc/security/limits.conf文件
# vim /etc/security/limits.conf
在文件的最后增加以下四行
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  1024
oracle              hard    nofile  65536


5.修改/etc/pam.d/login文件
# vim /etc/pam.d/login
在文件末尾增加以下两行
session required /lib64/security/pam_limits.so
session required pam_limits.so


6.新建所需组及用户
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba oracle
# passwd oracle 


7.修改Oracle .bash_profile
export PATH
export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.3.0/dbhome_1

export ORACLE_SID=orcl

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="AMERICAN_AMERICA.AL32UTF8"

export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"

# su - oracle， source .bash_profile使其立即生效
8.建立用户并授权
#mkdir -p /opt/oracle
#chown -R oracle:oinstall /opt/oracle
#chmod 775 /opt/oracle


9.解压ORACLE文件
#unzip 10201_database_linux32.zip
解压后，得到database目录


10.su root下
xhost +


11.su oracle
运行./runInstaller
