Подготовка:
* Установка всех зависимостей для устанавливаемой БД
# yum install oracle-rdbms-server-11gR2-preinstall # yum update
* Отключение фаервола
# service iptables stop # chkconfig iptables off
* Доп. настройка
Set the password for the "oracle" user.

# passwd oracle
Amend the "/etc/security/limits.d/90-nproc.conf" file as described below.

# Change this * soft nproc 1024 # To this * - nproc 16384
Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=permissive
Once the change is complete, restart the server.

If you have the Linux firewall enabled, you will need to disable or configure it, as shown here or here.

Create the directories in which the Oracle software will be installed.

# mkdir -p /u01/app/oracle/product/11.2.0/db_1 # chown -R oracle:oinstall /u01 # chmod -R 775 /u01

Login as the oracle user and add the following lines at the end of the ".bash_profile" file.

# Oracle Settings TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIR ORACLE_HOSTNAME=ol6-112.localdomain; export ORACLE_HOSTNAME ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME ORACLE_SID=DB11G; export ORACLE_SID PATH=/usr/sbin:$PATH; export PATH PATH=$ORACLE_HOME/bin:$PATH; export PATH LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

Поправляем /etc/hosts, вкорячиваем туда ol6-112.localdomain на 127.0.0.1
