[Root@localhost ~]# Su-root

[Root@localhost ~]# vi/etc/security/limits.conf

1.2, modify the/etc/pam.d/login file.

Enter the command: Vi/etc/pam.d/login to add the following content to the file.

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

1.3, modify the Linux kernel, modify the/etc/sysctl.conf file.

Enter the command: vi/etc/sysctl.conf to add the following content to the file.

Fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152 Kernel.shmmax
= 2147483648
Kerne L.shmmni = 4096
Kernel.sem = 32000 128
net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_de
Fault = 4194304
Net.core.rmem_max = 4194304
net.core.wmem_default = 262144 Net.core.wmem_max
= 1048576

Use the # notation to comment out the original configuration.

# Controls The maximum shared segment size, in bytes

#kernel. Shmmax = 68719476736

# Controls The maximum number of shared memory segments, in pages

#kernel. Shmall = 4294967296

Enter the command: Sysctl-p to make the/etc/sysctl.conf configuration file effective immediately.

1.4, modify/etc/profile.

Enter the command: Vi/etc/profile to add the following content to the file.

if [$USER = "Oracle"]; Then 
if [$SHELL = "/bin/ksh"]; then 
  ulimit-p 16384 ulimit-n 65536 
else 
  ulimit-u 16384-n />fi
fi

1.5, create users and groups.

To create a user group, enter a command:

Groupadd  oinstall 
groupadd  dba

Create Oracle User, primary group is Oinstall, Deputy Group DBA, enter command:

USERADD-G oinstall-g dba-m Oracle

Set User Oracle password, enter two times password, enter command:

passwd  Oracle

1.6, create the database software directory and data file storage directory.

Mkdir/home/oracle/app
mkdir/home/oracle/app/oracle
mkdir/home/oracle/app/oradata
mkdir/home/oracle /app/oracle/product

Modify directory permissions, change the directory owner to all Oracle users, enter the command:

Chown-r Oracle:oinstall/home/oracle/app

1.7, configure the Oracle user environment variables.

Switch to the Oracle user with the command su-oracle.

Su-oracle

Enter command: Vi. bash_profile, add the following content to the file.

Umask 022
export Oracle_base=/home/oracle/app
export oracle_home= $ORACLE _base/oracle/product/11.2.0/ Dbhome_1
export ORACLE_SID=ORCL
export path= $PATH: $HOME/bin: $ORACLE _home/bin
Export ld_library_path=$ Oracle_home/lib:/usr/lib

[Root@localhost ~]# Su-oracle

[Oracle@localhost ~]$ Vi. Bash_profile

1.8, upload Oracle installation files

Upload Oracle installation files to Linux server.

Open Xshell, create a new connection, enter an IP address and port, and connect using the SSH protocol.

Enter a user name and password.

Using Xshell and xftp tools to upload files, connect Linux in Xshell, click on the icon in the red wireframe to open the xftp.

Upload installation files

P10404530_112030_linux-x86-64_1of7.zip

P10404530_112030_linux-x86-64_2of7.zip

Upload to the/tmp directory below.

1.9, decompression installation files

Enter the TMP directory and use the Unzip command to extract the files.

[Root@localhost tmp]# CD/
[root@localhost/]# cd/tmp
[root@localhost tmp]# Unzip-p10404530_112030_ LINUX-X86-64_1OF7.ZIP-D/tmp
[root@localhost tmp]# unzip p10404530_112030_linux-x86-64_2of7.zip-d/tmp

After the decompression is complete, there will be a database folder in the TMP directory.

Second, install Oracle 11.2 products

Switch to the Oracle user with the command su-oracle, and execute the installation command./runinstaller, as follows.

[Root@localhost database]# su-oracle
[oracle@localhost ~]$ cd/tmp/database
[Oracle@localhost database]$ display=192.168.0.107:0.0
[oracle@localhost database]$ export DISPLAY
[oracle@localhost database]$ Export  lang=en-us
[Oracle@localhost database]$./runinstaller

If you are remotely connected to a Linux server installation, you need to enter a command

display=192.168.0.107:0.0//Here is the IP address of the local computer, not the IP address of the server
Export Display//install interface map to local computer
Export lang=en-us//If the installation interface is garbled, the text will not display, you need to enter the command

If you are installing directly on a Linux server, you do not need to enter the three-line command above, just enter

Su-oracle
Cd/tmp/database
./runinstaller

This is the way in which the following sections of this article are similar.

Execute the installation command. After/runinstaller, the following message is displayed:
