RedHat install Oracle

Version

Linux: RedHat 5.6

Oracle: 1, 10.2

Preparations before installation

1. Modify the operating system version. Before oracle is installed, it will verify the operating system version. If you do not know the version, it cannot be installed.

1. Vi/etc/redhat-release
3. # Comment out the original content, change the content to redhat-4

2. Create an oracle user

2.1 create a user group

1. Groupadd oinstall
2. Groupadd dba

2.2 create a user

1. Useradd oracle-g oinstall-G dba

2.3 create a user's password

1. Passwd oracle

Enter the password twice

3. Prepare the installation directory
3.1 create a directory

1. Mkdir/usr/local/src/oracle10g
3. Mkdir/usr/local/src/oracle10g/oradata

3.2 assign directory permissions to oracle users

1. Chown-R oracle: oinstall/usr/local/src/oracle10g
3. Chown-R oracle: oinstall/usr/local/src/oracle10g/oradata
5. Chmod-R 755/usr/local/src/oracle10g
7. Chmod-r 755/usr/local/src/oracle10g/oradata

4. Switch oracle users
This step is very important. Do not use su oracle. Log On As an oracle user after logging out of the current root user.
5. Set oracle user environment variables
5.1 modify Environment Variables
Edit ~ Path. bash_profile

1. Vi. bash_profile

Add the following content to the end of the file:

1. Export PATH
2. Export ORACLE_BASE =/usr/local/src/oracle10g
3. Export ORACLE_HOME = $ ORACLE_BASE/product/10.2.0/db_1
4. Export ORACLE_SID = risespdb
5. Export PATH = $ PATH: $ HOME/bin: $ ORACLE_HOME/bin
6. Export LD_LIBRARY_PATH = $ ORACLE_HOME/lib:/usr/lib

5.2 effective environment variables

1. Source ~ /. Bash_profile

Install oracle
1. Extract

If the oracle_installation file is 1021_database_linux32.zip

1. Unzip 10201_database_linux32.zip 10201_database_linux32
2. Cd 10201_database_linux32
3. Chmod a + rwx-R database

2. Run and install Use the oracle user to log on from the graphic interface, If the current Redhat language environment is Chinese, the installation interface will see garbled characters. Just change the language environment.

1. Export LANG = en

Run the installation in the database directory.

1. ./RunInstall

There are various "Next Steps" until installation starts.
At the end of installation, two script files may fail to be executed due to permissions.
The Buddy couldn't remember the exact name. He wrote down where the two files were, and used the root user to log on to the directory where the files were located for execution.

1. ./(Script file name). sh

3. Modify the file

1. Vi/etc/oratab

Change content

1. Orcl:/usr/local/src/oracle10g/product/10.2.0/db_1: Y

Note that orcl is the Instance name, which must be consistent with the instance name of your database.

4. Modify $ ORACLE_HOME/bin/dbstart

1. Cd $ ORACLE_HOME
2. Cd bin
3. Vi dbstart

Set the following content

1. ORACLE_HOME_LISTNER =/ade/vikrkuma_new/oracle

Change

1. ORACLE_HOME_LISTNER = $ ORACLE_HOME

5. Start the database

1. ./Dbstart

6. Create a STARTUP script for the LEDs service.

Create a file named led under the/etc/init. d directory
Add the following content to the sorted led file (the script is used to search for non-original files on the Internet)

1. #! /Bin/bash
2. # Chkconfig:-85 15
4. # Description: oracle 10g is database. It is used to serve
5. # File:/etc/init. d/LED
7. # Run-level Startup script for the Oracle Instance, Listener, Web Interface
9. Export ORACLE_BASE =/usr/local/src/oracle10g
10. Export ORACLE_HOME = $ ORACLE_BASE/product/10.2.0/db_1
11. Export ORACLE_SID = orcl
13. ORA_OWNER = "oracle"
15. # If the executables do not exist, then display error
16. If [! -F $ ORACLE_HOME/bin/dbstart-o! -D $ ORACLE_HOME]
17. Then
18. Echo "oracle startup: can't start"
19. Exit 1
20. Fi
22. # The oracle10g database depending on parameter -- start, shutdown, restart
23. Case "$1" in
25. Start)
26. Echo-n "starting oracle :"
27. Su $ ORA_OWNER-c "$ ORACLE_HOME/bin/dbstart"
28. Touch/var/lock/oracle
29. Echo "OK"
30. ;;
32. Stop)
33. Echo-n "shutdown oracle :"
34. Su $ ORA_OWNER-c "$ ORACLE_HOME/bin/dbshut"
35. Rm-f/var/lock/oracle
36. Echo "OK"
37. ;;
39. Reload | restart)
40. $0 stop
41. $0 start
42. ;;
43. *)
45. Echo "Usage: 'basename $ 0' start | stop | restart | reload"
46. Exit 1
48. Esac
49. Exit 0

7. Authorize the file and add the service

1. Cd/etc/init. d
2. Chmod 755 LEDs
3. Chkconfig-add LEDs
4. Service terminated led start

This is a comprehensive task.
