Shulou(Shulou.com)06/01 Report--

Some time do not install oracle, feel a bit raw, so make a note, convenient later installation deployment, but also can share with you.

This installation is the process of deploying Oracle 11GR 2 under CentOs 6.4 (64bit)

You can go online to download the relevant package, oracle installation package is best to go to the official website to download, note: oracle installation package official website has two compressed files, after downloading need to extract in a folder inside to use oh--"Address:

www.oracle.com

First, check whether Linux is enough 1 G(here must pay special attention to a lot of students are not successful installation because of insufficient memory):

# grep MemTotal /proc/meminfo

MemTotal: 1250112 kB

Notice: The official documentation says

Minimum: 1 GB of RAM

Recommended: 2 GB of RAM or more

Check the size of the swap partition:

# grep SwapTotal /proc/meminfo

SwapTotal: 2523128 kB

Notice: The official documentation says

RAM

Swap Space

Between 1 GB and 2 GB

1.5 times the size of the RAM

Between 2 GB and 16 GB

Equal to the size of the RAM

More than 16 GB

16 GB

3. Check whether there is enough space for/tmp for 1 G:

# df -h /tmp

File system capacity used Available Used %% mount points

/dev/mapper/vg_studyserver-lv_root

50G 13G 35G 26% /

(As long as the/partition is large enough to be larger than 25GB,/tmp will be larger than 1 GB)

4. Check the version of Linux system, mainly to see whether it is 64bit or 32bit:

# cat /proc/version

Linux version 2.6.32-358.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Fri Feb 22 00:31:26 UTC 2013

5. Check the rpm package:

Command to see if this package is installed:

The tips are as follows:

# rpm -aq |grep binutils ---> Examples-> Find out if this package is installed

# ls -l compat-libstdc++*--> Example--> Find out if there is this rpm package in the mirror

# yum -y install unixODBC-devel-2.2.14-12.el6_3.i686 ----> Notice this example

If not installed, install yum or rpm.

The contents in the above table are copied from the official documentation. I use CentOs 6.4 X86_X64 here, which is the same as Red Hat Enterprise Linux 6.

VI. Configure IP and hostname:

1、

first configure

Static IP (must be static): this is to enable Linux to access the Internet

2、

modify the configuration file

Vi /etc/hosts

1. Configure static IP first (note that IP must be static), so that Linux and host machines under virtual machines ping each other;

2. Modify the configuration file

# vi /etc/hosts

The file/etc/hosts contains the following:

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.1.111 oracle

#::1 localhost6.localdomain6 localhost6

Explanation: /ext/hosts only red useful---> 192.168.1.111 oracle where 192.168.1.111 is the Linux IP address, oracle is the Linux host name

You can check the host name by # hostname. If not, see the next step.

One more change (change Linux hostname):

#vi /etc/sysconfig/network

Change HOSTNAME= to oracle consistent with the oracle of/etc/hosts above;

VII. Confirm whether selinux and iptables are disabled:

# vi /etc/selinux/config

SELINUX=disabled This step must be set, otherwise there will be problems

service iptables stop Close firewall

Create the required operating system users and groups:

# /usr/sbin/groupadd oinstall

# /usr/sbin/groupadd -g 502 dba

# /usr/sbin/useradd -u 502 -g oinstall -G dba oracle

# passwd oracle

9. Create oracle base directory folder

# mkdir -pv /u01/app/oracle

# chown -R oracle:oinstall /u01/

# chmod -R 775 /u01/app/oracle

Edit environment variables (/home/oracle/.bash_profile)

# su - oracle

# vi .bash_profile (screenshot at the end)

Add the following:

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1

export ORACLE_SID=orcl

export NLS_LANG=American_America.ZHS16GBK

export PATH=$PATH:$ORACLE_HOME/bin

export LANG=en_US

11. Restart once, and then:

Here you need to upload the oracle installation package to Linux using ssh secure and other tools, but remember: change the permissions of the decompressed installation package oracle:oinstall

# xhost +

access control disabled, clients can connect from any host

# su - oracle --> Then log in with oracle user

$ cd /u01/database ---> Then switch to oracle 11g r2 source file directory

$ ./ runInstaller ---》Execute./ runInstaller

Then you can install it. The installation process and the installation under window are almost the same. In the middle, you may need to execute several scripts.
