Configure the linux server to support Xbrowser remote Desktop connections

Introduction to related configuration files

1. The default configuration files for the 2./etc/inittab-init process, the main configuration file of the 2./etc/inittab-init process, the custom configuration file of 3./etc/gdm/custom.conf-GNOME, view the defaults.conf from that software package: # rpm-qf / usr/share/gdm/defaults.conf gdm-2.16.0-59.el5

View the description of the gdm package:

# rpm-qf / usr/share/gdm/defaults.conf gdm-2.16.0-59.el5# rpm-qi gdm Name: gdm Relocations: (not relocatable) Version: 2.16.0 Vendor: Red Hat Inc.Release: 59.el5 Build Date: Saturday, October 29, 2011 05:54:09 Install Date: Monday, January 05, 2015 09:54:18 Build Host: hs20-bc2-3.build.redhat.comGroup: User Interface/X Source RPM: gdm-2.16.0-59.el5.src.rpmSize: 11673818 License: LGPL/GPLSignature: DSA/SHA1 On Wednesday, November 30, 2011, 22:34:06, Key ID 5326810137017186Packager: Red Hat, Inc. URL: ftp://ftp.gnome.org/pub/GNOME/sources/gdmSummary: GNOME display Manager. Description: Gdm (GNOME display Manager) is a highly configurable reimplementation of xdm (X display Manager). Gdm allows you to log in on a system running an X window system and supports several X sessions running simultaneously on your local machine.

Server configuration

1. Change the defaults.conf file permissions. The default is read-only chmod 700 / usr/share/gdm/defaults.conf2. Configure as follows-Edit / usr/share/gdm/defaults.confEnable=trueDisplaysPerHost=10Port=177AllowRoot=trueAllowRemoteroot=trueAllowRemoteAutoLogin=false3. Do the following configuration-edit / etc/gdm/ custom.confs [xdmcp] Enable=14. Do the following configuration-Edit / etc/inittab (do not modify the original setting, add the following line at the end) x:5:respawn:/usr/sbin/gdm# this setting can be tested without adding 5. Reload GNOME Desktop configuration init 3 nit 5

Mount the optical drive to install the software name required for the oracle software installation:

Create oracle users and groups:

# groupadd oinstall# groupadd dba # useradd-g oinstall-G dba oracle

Use the xftp that comes with Xmanager Enterprise 4 to upload oracle software and extract it:

# mkdir / oraapp # cd / orapp# unzip linux.x64_11gR2_database_1of2.zip & & unzip linux.x64_11gR2_database_2of2.zip# chown-R oracle:oinstall / oraapp/database

Configure files related to system core parameters: / etc/sysctl.conf

# vi / etc/sysctl.conf fs.aio-max-nr = 1048576fs.file-max = 6815744kernel.shmall = 2097152kernel.shmmax = 536870912kernel.shmmni = 4096kernel.sem = 32000 100 128net.ipv4.ip_local_port_range = 9000 65500net.core.rmem_default = 262144net.core.rmem_max = 4194304net.core.wmem_default = 262144net.core.wmem_max = 1048576

Use the system core parameters to take effect:

# sysctl-p

Modify Shell Limits to improve the efficiency of Oracle execution:

# vi / etc/security/limits.conforacle soft nofile 131072oracle hard nofile 131072oracle soft nproc 131072oracle hard nproc 131072oracle soft core unlimitedoracle hard core unlimitedoracle soft memlock 50000000oracle hard memlock 50000000

Create an oracle installation directory

# mkdir-p / u01/app/oracle# chown-R oracle:oinstall / u0mm chmod-R 755 / U01

Modify the oracle environment variable:

# my oracle setexport TMP=/tmpexport TMPDIR=$TMPexport EDITOR=vimexport ORACLE_BASE=/u01/app/oracleexport ORACLE_HOME=$ORACLE_BASE/product/11.2/db_1export ORACLE_SID=secoolerexport NLS_LANG=american_america.zhs16gbkexport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/libexport PATH=$ORACLE_HOME/bin:$PATHumask 022

Test whether the oracle environment variable is configured successfully:

$echo $ORACLE_HOME/u01/app/oracle/product/11.2/db_1 [oracle@dba ~] $echo $ORACLE_BASE/u01/app/oracle

Enter the graphical environment to install

# xhost + # export DISPLAY=192.168.1.4:0.0# su-oracle # cd / oraapp/database/$. / runInstaller if you don't want oracle to check the prerequisites. / runInstaller-ignoresysprereqs

The first interface for oracle11gR2 installation:

Do not receive security updates next step

Choose to install only the database software next

The next step in installing a single instance database

Default next step

The next step of the enterprise edition

Default next step

Default next step

Default next step

Prerequisite check to ensure that all dependent packages are installed

Complete

During the installation process, you need to run two scripts as follows

/ u01/app/oraInventory/orainstRoot.sh/u01/app/oracle/product/11.2/db_1/root.sh runs the above two scripts as oracle user environment root: [root@dba Server] # su-oracle [oracle@dba ~] $su password: # cd $ORACLE_HOME#. / root.sh # cd $ORACLE_BASE#.. / oraInventory/orainstRoot.sh
