Linux_install_oracle_11g:

To check the server's memory, you can use the following command:

[] # grep MemTotal / proc/meminfo

Check memory and swap space: Oracle requires at least 1G of memory. When the memory is 1G-2G, swap space should be

Beg for

1.5 times memory:

[] # free

To view the current server swap swap partition size, you can use the following command:

[] # grep SwapTotal / proc/meminfo

To view the current shared memory of the system, you can use the df command, for example:

[root@jssnode1~] # df-h / dev/shm

View system architecture

[root@jssnode1~] # uname-m

First of all, / tmp must have at least 1g of free space. Check the disk space of / tmp, or you can check it through the df command, for example

Such as:

[root@jssnode1~] # df-h / tmp

Software environment check

[root@jssnode1~] # cat / etc/issue

You can view the kernel version through the uname command, for example:

[root@jssnode1~] # uname-r

Find the missing package from the "server" directory of CD and copy it to the newly created directory / rpms:

Remount:

Different operating systems and architectures require different system packages to be installed. Here, only think twice about using 64bit.

For example, OracleEnterpriseLinux5 requires the following system packages: (29 packages)

Binutils-2.17.50.0.6

Compat-libstdc++-33-3.2.3

Compat-libstdc++-33-3.2.3 (32bit)

Elfutils-libelf-0.125

Elfutils-libelf-devel-0.125

Gcc-4.1.2

Gcc-c++-4.1.2

Glibc-2.5-24

Glibc-2.5-24 (32bit)

Glibc-common-2.5

Glibc-devel-2.5

Glibc-devel-2.5 (32bit)

UnixODBC-2.2.11

UnixODBC-2.2.11 (32bit)

UnixODBC-devel-2.2.11

UnixODBC-devel-2.2.11 (32bit)

To check that the installation of the specified system package is still quite large, you can use the rpm-q command, for example

Such as:

[root@jssnode1~] # rpm-aq gcc

[root@jssnode1~] # rpm-aq grep | gcc

[root@localhost /] # rpm-aq | grep compat

[root@localhost /] # rpm-aq | grep elfutils

[root@localhost /] # rpm-aq | grep libstdc

[root@localhost /] # rpm-aq | grep sysstat

[root@localhost /] # rpm-aq | grep unixODBC

[root@localhost /] # rpm-aq | grep libaio

[root@localhost /] # rpm-aq | grep libgcc

[root@localhost /] # rpm-aq | grep make

[root@localhost /] # rpm-aq | grep ksh

[root@localhost /] # rpm-aq | grep binu

.

Create a directory for uninstalled packages:

[root@linuxserv5 ~] # mkdir / rpms

Get the uninstalled package:

[root@localhost rpms] # ls

Compat-libstdc++-33-3.2.3-61.i386.rpm unixODBC-2.2.11-7.1.i386.rpm

Libaio-devel-0.3.106-3.2.i386.rpm unixODBC-devel-2.2.11-7.1.i386.rpm

Sysstat-7.0.2-3.el5.i386.rpm

For system packages that have not yet been installed, you can also install them through the rpm command, such as installing sysstat system packages.

The line operation is as follows (of course, rpm must first find the package before installing, usually to the installation CD of the operating system.

Looking for

If it is not on the CD, you can also check the operating system website):

[root@localhost rpms] # rpm-Uvh *

Or install one by one:

[root@jssnode1Server] # rpm-ivh sysstat-7.0.2-3.el5.x86_64.rpm

Modify Linux kernel parameters

Use the vi command to edit the / etc/sysctl.conf file, for example:

Press the "o" key to enter the paste, ": wq" to save exit:

[root@jssnode1Server] # vi/etc/sysctl.conf

Add the following to the file:

Fs.aio-max-nr=1048576

Fs.file-max=6815744

Kernel.shmall=2097152

Kernel.shmmax=536870912

Kernel.shmmni=4096

Kernel.sem=25032000100128

Net.ipv4.ip_local_port_range=900065500

Net.core.rmem_default=262144

Net.core.rmem_max=4194304

Net.core.wmem_default=262144

Net.core.wmem_max=1048586

Or:

Kernel.sem = 250 32000 100 128

Net.ipv4.ip_local_port_range = 1024 65000

Net.core.rmem_default = 4194304

Net.core.rmem_max = 4194304

Net.core.wmem_default = 262144

Net.core.wmem_max = 262144

Make the kernel parameters take effect immediately:

[root@linuxserv7] # sysctl-p

Use the groupadd command to create a group as follows:

[root@jssnode1~] # groupadd-g 502 dba

Then create an OracleInventory group, whose name is usually defined as oinstall, with the following creation command:

[root@jssnode1~] # groupadd oinstall

Generally speaking, the owner user who created ORACLE is also ordered to oracle, and the operations are as follows:

[root@jssnode1~] # useradd-u 502-g oinstall-G dba oracle

Then set the password for the user as follows:

[root@jssnode1~] # passwd oracle

Verify the nobody user:

[root@localhost rpms] # id nobody

Uid=99 (nobody) gid=99 (nobody) groups=99 (nobody)

Context=root:system_r:unconfined_t:SystemLow-SystemHigh

[root@localhost rpms] # id oracle

Uid=501 (oracle) gid=501 (oinstall) groups=501 (oinstall), 502 (dba)

Context=root:system_r:unconfined_t:SystemLow-SystemHigh

Create a file system / db (if / space size allows, you can also create a directory directly under the / file system

/ db).

Change the owner of the file system / db so that the database is later mounted on the / db file system:

[root@localhost rpms] # cd /

[root@localhost /] # ls

Bin dev home lost+found misc net proc rpms selinux sys usr

Boot etc lib media mnt opt root sbin srv tmp var

[root@localhost /] # mkdir db

[root@localhost /] # ls

Bin dev lib misc opt rpms srv usr

Boot etc lost+found mnt proc sbin sys var

Db home media net root selinux tmp

[root@localhost /] # chown oracle:oinstall / db

[root@linuxserv7 ~] # chown oracle:oinstall / db/sw

[root@localhost /] # mkdir / db/sw

[root@localhost /] #

Set the environment variable for the oracle user:

Edit the .bash _ profile parameter file with the text editor vi:

[oracle@linuxserv7 ~] $pwd

/ home/oracle

[oracle@linuxserv7 ~] $vi .bash _ profile

# .bash _ profile

# Get the aliases and functions

If [- f ~ / .bashrc]; then

. ~ / .bashrc

Fi

# User specific environment and startup programs

ORACLE_SID=sdzy

ORACLE_BASE=/db/oracle

ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1

Export ORACLE_SID ORACLE_BASE ORACLE_HOME

PATH=$PATH:/$ORACLE_HOME/bin:$HOME/bin

Export PATH

~

In the previous step, you can set it as follows:

/ *

Finally, use the chown command to change the owner of the directory to oracle:

[root@jssnode1~] # chown-Roracle:oinstall/data/ora11g

[root@jssnode1~] # chown-Roracle:oinstall/data/software

Use the vi command to edit / home/oracle/.bash_profile, adding the following:

ExportTMP=/tmp

ExportTMPDIR=$TMP

ExportORACLE_BASE=/data/ora11g

ExportORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

ExportORACLE_SID=jssdb

After some preparation, we finally entered the installation step. Here we use OUI to install ORACLE because

This operation needs to be done under the window interface. As the oracle user starts to the window state, open a terminal.

Tip:

If you start as a root user, you need to execute the following first:

[root@jssnode1~] # xhost+

Access control disabled,clients can connect from any host

Close all connections to execute successfully

/ *

LINUX sets xhost access control disabled, clients can connect from any host

Step 1: log in to linux with root and start the vnc service

Step 2: according to the port of vnc, set export DISPLAY=localhost:1 (1 means that vnc is in the first

Launched on tty)

Step 3: execute xhost + and prompt "access control disabled, clients can connect"

"from any host" is correct.

The operation log under linux is as follows:

New 'localhost:1 (root)' desktop is localhost:1

Starting applications specified in / root/.vnc/xstartup

Log file is / root/.vnc/localhost:1.log

/

[root@jssnode1~] # su-oracle

[oracle@jssnode1~] $

Go to the installation directory of the oracle software and execute runInstall:

[oracle@jssnode1~] $cd / db/sw/database/

[oracle@jssnode1database] $. / runInstaller

StartingOracleUniversalInstaller...

To set the environment variable, log in to the IP address of the client (the local remote login using SecureCRT), note

Start

Xmanager passive and start X11 in the SecureCRT setting.

[oracle@localhost Disk1] $export DISPLAY=134.98.105.169:0.0

[oracle@localhost Disk1] $

[root@jssnode1~] # su-root

[root@linuxserv7 ~] # sh / db/or acle/oraInventory/orainstRoot.sh

[root@linuxserv7 ~] # sh / db/ oracle/product/11.1.0/db_1/root.sh

$ORACLE_HOME/bin/netca

[oracle@linuxserv7 ~] $netca

[oracle@linuxserv7 ~] $dbca

Instead of using remote management tools to manage desktops, later positioning is a problem with xhost. The solution is as follows:

1 use root users to log in, check the DISPLAY variable-echo $DISPLAY, and make sure it is ": 0.0"

2 run xclock to ensure that the clock can be ejected

3 run "xhost +", the explanation of this command:

+

+

Because Xserver does not allow graphics from other users' graphics programs to be displayed on the current screen by default. If necessary

If you want the graphics of another user to be displayed on the current screen, you should use the user who is currently logged in, that is, before switching identities.

The user executes the following command

Xhost +

This command will allow graphics programs started by other users to display graphics on the current screen.

Xhost is used to control X server access.

Usually when you log in from hostA to hostB to run applications on hostB

As an application, hostA is client, but as a graphic,

It is displayed on hostA and needs to use hostA's Xserver, so hostA is

Server. So you need to run xhost + on hostA before logging in to hostB

To enable other users to access hostA's Xserver.

Xhost + enables all users to access Xserver.

Xhost + ip enables users on ip to access Xserver.

Xhost + nis:user@domain enables nis user user on domain to access

Xhost + inet:user@domain makes it accessible to inet users on domain.

+

4 switch to oracle, run. / runInstall to install.
