Install oracle on Centos6

Install oracle on Centos6

It is really not easy to install oracle on linux. A lot of dependent libraries need to be installed. After a long time, the installation is successful. Record the installation to prevent subsequent installation, because I can't remember the databases that need to be depended on.

1. Create an oracle user, user group, and installation directory:

Create oracle users and user groups

Groupadd oinstall # create a user group oinstall

Groupadd dba # create a user group dba

Useradd-g oinstall-g dba-m oracle # create an oracle user and add it to the oinstall and dba user groups

Passwd oracle # Set the user's oracle login password and enter the password twice as prompted

Create installation directory

Mkdir-p/opt/oracle/app # oracle database installation directory

Mkdir-p/opt/oracle/app/oracle # directory of the oracle Database Configuration File

Mkdir-p/opt/oracle/app/oradata

Mkdir-p/opt/oraInventory

Chown-R oracle: oinstall/opt/oraInventory

Chown-R oracle: oinstall/opt/oracle # grant permissions to oracle users and user groups oinstall

2. Modify the System ID (oracle does not support CentOS installation by default)

Vi/etc/redhat-release # Edit

CentOS release 6.5 (Final)

To: redhat-5

3. Configure the user environment

Vi/home/oracle/. bash_profile

Export PATH
Export ORACLE_BASE =/opt/oracle
Export ORACLE_HOME = $ ORACLE_BASE/product/11.2.0/db_1
Export ORACLE_SID = orcl
Export ORACLE_TERM = xterm # window installation mode
Export PATH = $ ORACLE_HOME/bin: $ PATH
Export LD_LIBRARY_PATH = $ ORACLE_HOME/lib:/usr/lib

Export NLS_LANG = AMERICAN_AMERICA.ZHS16GBK # Set the Oracle client character set. If the character set is set, it must be consistent with the character set during Oracle installation, for example, ZHS16GBK; otherwise, Chinese characters may be garbled during data import and export

4. Disable selander.

Vi/etc/selinux/config # edit the configuration file

# SELINUX = enforcing # comment out

# SELINUXTYPE = targeted # comment out

SELINUX = disabled # Add

5. configure the firewall to enable port 1521

Vi/etc/sysconfig/iptables # edit the firewall configuration file and add the following content

-A input-m state -- state NEW-m tcp-p tcp -- dport 1521-j ACCEPT

/Etc/init. d/iptables restart # restart the firewall to make the configuration take effect.

Set DISPLAY

Export DISPLAY = 192.168.193.110

Vi/etc/inittab

Id: 3: initdefault: # Change 3 to 5 (the Desktop system can be started successfully only after it is installed. If the Desktop system is not installed and oracle cannot be installed, install the Desktop command yum groupinstall-y "Desktop ")

6. restart the system

Shutdown-r now

7. decompress the oracle zip package

Unziplinux.x64_11gR2_database.zip

If no unzip command is prompted, install yum install-y zip unzip

8. Grant the decompressed directory to the oracle user.

Chown-R oracle: oinstall/opt/linux. x64_11gR2_database

9 switch users

Su oracle

10. Enter the directory where the runInstaller of the execution file is located.

Cd/opt/linux. x64_11gR2_database/database

In this case, the runInstaller in the directory does not have the execution permission. Authorize

Chmod 755 runInstaller

Install oracle

Libraries installed before installation

Yum install-y gcc * gcc-c ++-* glibc-devel-* glibc-headers-* compat-libstdc * elfutils-libelf-devel * libaio- devel * sysstat * unixODBC-* pdksh -*

Install oracle

./RunInstaller

The file/opt/linux. x64_11gR2_database/database/install/. oui is not authorized.

Chmod 755/opt/linux. x64_11gR2_database/database/install/. oui

Chmod 755/opt/linux. x64_11gR2_database/database/install/unzip

After the installation, the installation page will be displayed.

There may be another problem, that is, if the Chinese version of the installation is installed and the installation interface may be garbled, cancel the installation and execute

Export LANG = en_US.UTF-8

You can install it again.

You can follow the prompts to continue the installation.

2. After the installation is complete, set the listener before creating the database.

Netca # configure listener commands

The listener settings page will be called up.

Complete the next step

Create an Oracle database instance orcl

Dbca # Start the oracle instance installation interface,

Follow the prompts to install the SDK step by step.

There are four options in this step. Character Sets the database language. If the preceding environment variable is set, this step needs to correspond

For example

Select ZHS16GBK-GBK 16-bit Simplified Chinese

National character set: AL16UTF16-Unicode UTF-16 Universal character set

Default language: Simplified Chinese

Default region: China

If File '/etc/oratab' is not accesssiblei exists in the window that is then dyed, run it as root

Note: If the above prompt appears, you can log on with the root account after the installation is complete and execute the following two Commands

./Opt/oracle/app/product/11.2.0/db_1/root. sh

./Opt/oraInventory/orainstRoot. sh

Generate the/etc/oratab file.

4. Start the oracle database

Su-oracle # Switch to oracle user

Sqlplus/nolog # Enter sqlplus

Conn/as sysdba # Log On as a super Administrator

Startup # Start a database instance

Quit # exit

Lsnrctl start # start the listener

Startup parameter description:

Startup # Start the database instance and open the database without any parameters.

Startup nomount # Only start the database instance, do not open the database, is generally used to create a new database

Startup mount # Start the database instance and load the database, but do not open the database. It is generally used to modify the Database Name and manage it.

8. Close the oracle database

Su-oracle # Switch to oracle user

Lsnrctl stop # disable listener

Sqlplus/nolog # Enter sqlplus

Shutdown immediate # Shut Down database instances

Quit # exit

Shutdown parameter description:

Normal # Wait until all users are disconnected. New connections are not allowed after the command is executed.

Immediate # Wait until the user completes the current statement and disconnect the user. New users are not allowed to connect.

Transactional # Disconnect after the user completes the current transaction and do not allow new users to connect

Abort # force disconnect and close the database

The preceding three methods do not cause database errors. The last method is not recommended unless otherwise specified,

Shutdown immediate is generally used to close the database.

Note: If you execute shutdown immediate, The ORA-01012: not logged on error occurs.

Run the following statement first.

Ps-ef | grep ora_dbw0 _ $ orcl

Kill-9 pid # pid is the process number

Here, orcl is the SID of the database.

9. Set oracle startup

Note: Oracle is not automatically started after Oracle is installed in linux.

1. su-root # Switch to the root user

/Data/oracle/product/11.2.0/db_1/root. sh # Run the script to generate the/etc/oratab file.

/Data/oraInventory/orainstRoot. sh

2. vi/etc/oratab # Edit

Find: $ ORACLE_SID: $ ORACLE_HOME: <N | Y>:

Cancel the # comment and modify it:

Orcl:/data/oracle/product/11.2.0/db_1: Y # orcl indicates the name of the oracle database instance.

: Wq! # Save and exit

3. Edit vi/data/oracle/product/11.2.0/db_1/bin/dbstart #

Found: ORACLE_HOME_LISTNER = $1

Changed to: ORACLE_HOME_LISTNER = $ ORACLE_HOME

4. vi/data/oracle/product/11.2.0/db_1/bin/dbshut # Edit

Found: ORACLE_HOME_LISTNER = $1

Changed to: ORACLE_HOME_LISTNER = $ ORACLE_HOME

5. Create an oracle Startup Script

Vi/etc/init. d/oracle # edit and add the following code
######################################## ##################
#! /Bin/sh
# Chkconfig: 0356 99 10
# Description: Startup Script for Oracle Databases
# Script path:/etc/init. d/oracle
# Author: www. osyunwei. comby qihang01
#
ORACLE_BASE =/data/oracle
ORACLE_HOME = $ ORACLE_BASE/product/11.2.0/db_1
ORACLE_SID = orcl
PATH = $ ORACLE_HOME/bin:/usr/sbin: $ PATH
Export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
#
ORA_OWNR = "oracle"
#
If [! -F $ ORACLE_HOME/bin/dbstart-o! -D $ ORACLE_HOME]
Then
Echo "Oracle startup: cannot start"
Exit 1
Fi
#
Case "$1" in
Start)
Su-$ ORA_OWNR-lc $ ORACLE_HOME/bin/dbstart
Echo "Oracle Start Succesful! "
;;
Stop)
#
Su-$ ORA_OWNR-lc $ ORACLE_HOME/bin/dbshut
Echo "Oracle Stop Succesful! "
;;
Restart)
$0 stop
$0 start
;;
*)
Echo $ "Usage: 'basename $ 0' {start | stop | restart }"
Exit 1
Esac
Exit 0

6. Restore the Operating System ID

Vi/etc/redhat-release # Edit

Put: redhat-4

Change to: CentOS release 5.8 (Final)

: Wq! # Save and exit

7. Change the default startup level to 3.

Vi/etc/inittab # Edit

Id: 3: initdefault: # modify 5 to 3

: Wq! # Save and exit

8. Test

Shutdown-r now # restart the system

Service oracle start # start oracle

Service oracle stop # disable oracle

/Etc/init. d/oracle restart # restart oracle

Su-oracle # Switch to oracle user

Dbstart # Start oracle

Dbshut # disable oracle

Ps-efw | grep ora # view oracle Processes

Ps-efw | grep LISTEN | grep-v gre # view oracle port listening

Lsnrctl status # view the oracle running status

So far, the installation of Oracle 11g R2 in CentOS is complete.

Additional reading:

Use a vnc remote connection to install Oracle. If an error occurs and the installation interface cannot be started, perform the following operations!

Log On with root ssh

Vncserver # Start vnc

New 'www: 1 (root) 'desktop is www: 1 # Remember www: 1, which will be used later!

Export DISPLAY = www: 1 # Input

Service vncserver start # start vnc

Use the vnc client root to log on

Xhost +

Su-oracle # Switch to oracle user

./RunInstaller # Run the installation
