rhel 6安装oracle 11g R2

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.(修改hosts文件)

127.0.0.1 localhost.localdomain localhost

#192.168.2.181 ol5-11gr2.localdomain ol5-11gr2

192.168.2.34 rhel localhost

2.修改参数文件，在红帽5以上系统中安装oracle 10g 与11g 最大的区别就在内核参数是不一样的。主要为红色的字符串

fs.suid_dumpable = 1

fs.aio-max-nr = 1048576

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 = 1048586

The current values can be tested using the following command.

/sbin/sysctl -a | grep <param-name>

Add or amend the following lines in the "/etc/sysctl.conf" file.

fs.suid_dumpable = 1

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

# semaphores: semmsl, semmns, semopm, semmni

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default=4194304

net.core.rmem_max=4194304

net.core.wmem_default=262144

net.core.wmem_max=1048586

Run the following command to change the current kernel parameters.

/sbin/sysctl -p

Add the following lines to the "/etc/security/limits.conf" file.

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 4096

oracle hard nofile 65536

oracle soft stack 10240 //这个可以不加

3.安装相关的rpm包

Install the following packages if they are not already present.

# From redhat enterprise 6_86

cd /media/RHEL_6.0 \ i386\ Disc \1 /Packages/ //此路径为我的系统光盘路径

rpm -Uvh binutils-2.*

rpm -Uvh compat-libstdc++-33*

rpm -Uvh compat-libstdc++-33*.i386.rpm

rpm -Uvh elfutils-libelf*

rpm -Uvh gcc-4.*

rpm -Uvh gcc-c++-4.*

rpm -Uvh glibc-2.*

rpm -Uvh glibc-common-2.*

rpm -Uvh glibc-devel-2.*

rpm -Uvh glibc-headers-2.*

rpm -Uvh ksh*

rpm -Uvh libaio-0.*

rpm -Uvh libaio-devel-0.*

rpm -Uvh libgomp-4.*

rpm -Uvh libgcc-4.*

rpm -Uvh libstdc++-4.*

rpm -Uvh libstdc++-devel-4.*

rpm -Uvh make-3.*

rpm -Uvh sysstat-7.*

rpm -Uvh unixODBC-2.*

rpm -Uvh unixODBC-devel-2.*

rpm -Uvh numactl-devel-*

//以上的包和内核参数在ORACLE安装检测系统过程中会有信息显示，ORACLE会提示你有哪些包没有安装，那些内核参数没有修改好。

4.创建用户和组

Create the new groups and users.

groupadd oinstall

groupadd dba

groupadd oper //可以不创建

groupadd asmadmin //可以不创建

useradd -g oinstall -G dba,oper,asmadmin oracle

passwd oracle

Note. We are not going to use the "asmadmin" group, since this installation will not use ASM.

AdditionalSetup

The following setup tasks must be performed regardless of which setup method you used previously.

Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=disabled

Alternatively, this alteration can be done using the GUI tool (Applications > System Settings > Security Level). Click on the SELinux tab and disable the feature. If SELinux is disabled after installation, the server will need a reboot for the change to take effect.

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/11.2.0/db_1 //红色部分可以不创建

chown -R oracle:oinstall /u01

chmod -R 775 /u01

xhost +<machine-name> //可直接输入xhost + 命令

5.登录oracle用户，修改oracle用户下的.bash_profile文件

Login as the oracle user and add the following lines at the end of the ".bash_profile" file, remembering to adjust them for your specific installation.

# Oracle Settings

TMP=/tmp; export TMP

TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=ol5-112.localdomain; export ORACLE_HOSTNAME

ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME

ORACLE_SID=DB11G; export ORACLE_SID

PATH=/usr/sbin:$PATH; export PATH

PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

6.安装

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

DISPLAY=<machine-name>:0.0; export DISPLAY

Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.

./runInstaller

Proceed with the installation of your choice. You can see the type of installation I performed by clicking on the links below to see screen shots of each stage.

Post Installation

Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.

DB11G:/u01/app/oracle/product/11.2.0/db_1:Y
