First, check the necessary conditions 1.1, check memory and swap partition

Oracle requires more than 2GB of memory

#查看内存大小grep MemTotal /proc/meminfo#查看交换区大小grep SwapTotal /proc/meminfo#也可以使用下面的命令查看内存大小free -m

Swap partition Requirements

Memory Size	Swap partition Requirements
1gb~2gb	1.5 times times the memory
2gb~16gb	is equal to the memory size
Greater than 16GB	16GB

1.2. Confirm the number of operating system bits

[root@FSWWOA /]# uname -mx86_64

X86_64: Indicates that Intel's processor is used, and that the operating system is 64-bit
I386: Indicates that it is a 32-bit

1.3. Check the hard disk space

#查看临时目录空间[root@FSWWOA /]# df -h /tmp#查看硬盘总空间[root@FSWWOA /]# df -h

Oracle installation is required to have at least 1GB of space in the/tmp directory.
The following are the required space for each version of Oracle installation

version	Space Required
Enterprise Edition (Corporate Edition)	4.7GB
Standard Edition (normal edition)	4.6GB

Second, install the necessary software

You first need to check the system version and then find the corresponding Linux version from the Oracle official documentation.

[root@FSWWOA /]# cat /proc/versionversion2.6.32-71.el6.x86_64 (root@CentOS6064version4.4201007264.4.4-13) (GCC) ) #12915:21:162012

The corresponding version of the Oracle official documentation is as follows

On Red Hat Enterprise Linux 6
2.6.32-71.el6.x86_64 or later

Then, depending on the Linux version, find the software that is necessary to install it, as follows

The following or later version of packages for Oracle Linux 6, Red Hat Enterprise Linux 6, and Asianux Server 4 must bes in Stalled:

binutils-2.20. Wuyi. 0. 2-5.11. El6 (x86_64) compat-libcap1-1.10-1(x86_64) compat-libstdc++- --3.2. 3-.El6 (x86_64) compat-libstdc++- --3.2. 3-.El6.

Check that the system installs the above software and install the software if it is not installed

Iii. creating Oracle Users and Groups

[root@FSWWOA /]# groupadd dba[root@FSWWOA /]# groupadd oinstall#添加用户[root@FSWWOA /]# useradd -g oinstall -G dba oracle#设置Oracle的密码[root@FSWWOA /]# pwd oracle oracle#这里密码使用：oracle

Iv. Modify the system Parameters 4.1, modify the user's shell restrictions

Modify the/etc/security/limits.conf file

vi /etc/security/limits.conf

Then add the following in the file

soft204716384soft102465536

4.2. Modify the/etc/pam.d/login file

vi /etc/pam.d/login

Then add the following in the file

session required /lib/security/pam_limits.sosession required pam_limits.so

4.3, modify the system core parameters

Modify the/etc/sysctl.conf file and add it to the vi /etc/sysctl.conf file

Fs. Aio-MAX-NR =1048576Fs. File-max =6815744Kernel. Shmall=2097152Kernel. Shmmax=536870912Kernel. Shmmni=4096Kernel. SEM= - 32000  -  -Net. IPV4. IP_local_port_range =9000 65500Net. Core. Rmem_default =262144Net. Core. Rmem_max =4194304Net. Core. Wmem_default =262144Net. Core. Wmem_max =1048576

sysctl -pthe execution is configured to take effect immediately. Use to sysctl -a view all system parameters.

V. Create an Oracle installation directory 5.1 Create an Oracle installation directory

cd /u01mkdir -p app/oracle/product/11.2.0/dbhome_1mkdir app/oradata

5.2 Modifying the directory owner

[[email protected] u01]chown-Roracle:oinstallapp[[email protected] u01]ll总用量 20drwxr-xr-xoracleoinstall  4096 11月 25 08:46appdrwx------root   root     16384 11月 24 14:29lost+found

Vi. Modifying system environment variables

Use the vi ~/.bash_profile open environment variable configuration file. Add the following:

export ORACLE_BASE=/u01/appexport ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/dbhome_1export ORACLE_SID=orclexport PATH=$PATH:$HOME/bin:$ORACLE_HOME/binexport LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/libexport

Then source ~/.bash_profile the use is configured to take effect immediately. Use env | grep ORACLE to view environment variable configurations.

Vii. Installing Oracle7.1 extracting Oracle installation files

Copy Oracle to a Linux server and unzip

unzip linux.x64_11gR2_database_1of2.zipunzip linux.x64_11gR2_database_2of2.zip

If you are using a CD-ROM installation, use a mount -t iso9660 /dev/dvd /mnt/dvd mounted disc

7.2 Setting up the installation environment

If the Linux system character encoding is Chinese, the Oracle installation interface will be garbled during installation. You can use it to export LANG=en_US change the character set of the session to the English character set and then install it without garbled characters.

In addition, the Oracle installation requires graphical interface support.
