2.DB安装前的准备工作

1.配置yum源

略

2.配置透明巨页

cat <<EOF  >> /etc/rc.local
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then  
    echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
   echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
fi
EOF
chmod 775 /etc/rc.d/rc.local

3.配置系统内核参数

cat <<EOF >> /etc/sysctl.conf
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1835008
kernel.shmmax = 7516192768
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.conf.all.rp_filter = 2
net.ipv4.conf.default.rp_filter = 2
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
EOF
/sbin/sysctl -p

4.配置系统资源参数

cat <<EOF >>/etc/security/limits.conf
oracle   soft   nofile    1024
oracle   hard   nofile    65536
oracle   soft   nproc    16384
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768
oracle   hard   memlock    134217728
oracle   soft   memlock    134217728
EOF

5.配置用户登录限制

echo "session required /lib/security/pam_limits.so" >> /etc/pam.d/login
echo "session required pam_limits.so" >> /etc/pam.d/login

6.配置资源限制

echo "if [ \$USER = \"oracle\" ]; then" >>/etc/profile
echo " if [ \$SHELL = \"/bin/ksh\" ]; then" >> /etc/profile
echo "   ulimit -p 16384" >> /etc/profile
echo "   ulimit -n 65536" >> /etc/profile
echo " else" >>/etc/profile
echo "   ulimit -u 16384 -n 65536" >> /etc/profile
echo " fi" >> /etc/profile
echo "umask 022" >> /etc/profile
echo "fi" >> /etc/profile

7.创建oracle用户

groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
groupadd -g 54324 backupdba
groupadd -g 54325 dgdba
groupadd -g 54326 kmdba
groupadd -g 54327 asmdba
groupadd -g 54330 racdba
useradd -u 54321 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba,oper oracle
echo "###################################"
echo "Password settings for oracle:"
echo oracle | passwd --stdin oracle

8.创建目录

mkdir  -p  /u01/app/oracle
chown -R  oracle:oinstall   /u01/app  /oradata /backup
chmod  -R  775  /u01/app   /oradata /backup

9.修改系统环境变量参数

9.1.配置10g和11g别名

[oracle@yuanzj.com:/home/oracle]$ cat .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
export PS1="[`whoami`@`hostname`:"'$PWD]$ '

alias 10g='source /home/oracle/.db10g'
alias 11g='source /home/oracle/.db11g'
[oracle@yuanzj.com:/home/oracle]$ ls -lh .db1*
-rw-r--r-- 1 oracle oinstall 816 Feb 16 16:14 .db10g
-rw-r--r-- 1 oracle oinstall 816 Feb 16 16:15 .db11g

9.2.Oracle10g环境变量：

[oracle@yuanzj.com:/home/oracle]$ cat .db10g 
export TMP=/tmp
export TMPDIR=$TMP

export ORACLE_HOSTNAME=yuanzj.com
export ORACLE_UNQNAME=orcl10g
export ORACLE_BASE=/u01/app/ora10g
export ORACLE_HOME=/u01/app/ora10g/product/10.2.0/db_1
export ORACLE_SID=orcl10g
export ORACLE_TERM=xterm

export PATH=/usr/sbin:/usr/local/bin:$PATH
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"

alias sqlplus='rlwrap sqlplus'
alias sas='rlwrap sqlplus / as sysdba'
alias scott='rlwrap sqlplus scott/tiger'
alias hr='rlwrap sqlplus hr/hr'
alias rman='rlwrap rman'

9.3.Oracle11g环境变量：

[oracle@yuanzj.com:/home/oracle]$ cat .db11g 
export TMP=/tmp
export TMPDIR=$TMP

export ORACLE_HOSTNAME=yuanzj.com
export ORACLE_UNQNAME=orcl11g
export ORACLE_BASE=/u01/app/ora11g
export ORACLE_HOME=/u01/app/ora11g/product/11.2.0/db_1
export ORACLE_SID=orcl11g
export ORACLE_TERM=xterm

export PATH=/usr/sbin:/usr/local/bin:$PATH
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"

alias sqlplus='rlwrap sqlplus'
alias sas='rlwrap sqlplus / as sysdba'
alias scott='rlwrap sqlplus scott/tiger'
alias hr='rlwrap sqlplus hr/hr'
alias rman='rlwrap rman'

注意：规划好不同版本数据库部署路径和实例名

10.配置selinux

cp /etc/selinux/config{,.bak} && sed -i '/SELINUX/s/enforcing/disabled/g;/SELINUX/s/permissive/disabled/g'   /etc/selinux/config
setenforce 0
getenforce

11.配置防火墙

service iptables stop
chkconfig iptables off

12.配置hosts文件

[oracle@yuanzj.com:/home/oracle]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.2.18 yuanzj.com yuanzj

注意：如果主机名是yuanzj.com类似的，一定要写yuanzj，不然oem启动失败
