# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
关闭防火墙：
[[email protected] ~]#chkconfig iptables off
[[email protected] ~]#service iptables stop
3、内核及其它相关参数设置

#
#Where:
#<domain> can be:

# - "hard" for enforcing hard limits
#
#<item> can be one of the following:
# - core - limits the core file size (KB)
# - data - max data size (KB)
# - fsize - maximum filesize (KB)
# - memlock - max locked-in-memory address space (KB)
# - nofile - max number of open files
# - rss - max resident set size (KB)
# - stack - max stack size (KB)
# - cpu - max CPU time (MIN)
# - nproc - max number of processes
# - as - address space limit
# - maxlogins - max number of logins for this user
# - maxsyslogins - max number of logins on the system
# - priority - the priority to run user process with
# - locks - max number of file locks the user can hold
# - sigpending - max number of pending signals
# - msgqueue - max memory used by POSIX message queues (bytes)
# - nice - max nice priority allowed to raise to
# - rtprio - max realtime priority
#
#<domain> <type> <item> <value>
#
#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#@student - maxlogins 4
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 4096
oracle hard nofile 65536
oracle soft stack 10240
# End of file
[[email protected] ~]# cat /etc/pam.d/login

unixODBC-devel-2.2.11 (64-bit) or later
unixODBC-2.2.11 (64-bit) or later
最好重启机器，以确保之前配置的相关内容生效。
5、创建用户及组
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba,oper oracle
passwd oracle
6、创建安装目录
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/11.2.0.4/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
If you are using X Emulation, login as root and issue the following command.
xhost +
7、设置oracle用户环境变量
Login as the oracle user and add the following lines at the end of the "/home/oracle/.bash_profile" file.
以oracle用户登录添加如下内容到这个文件：/home/oracle/.bash_profile
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=rusky-oel.com; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
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=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
===================================
修改系统环境变量/etc/profile
修改环境变量/etc/profile，加入以下内容
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
8、执行安装
installation
Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
DISPLAY=192.168.1.203:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
./runInstaller DISPLAY报错处理：http://www.cnblogs.com/rusking/p/4232835.html
