1.检查相关软件包
rpm -qa binutils compat-libstdc++-33 elfutils-libelf elfutils-l
ibelf-devel gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers ksh libaio
libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-de
vel pdksh-5.2.14
安装相关软件包
yum -y install binutils compat-libstdc++-33 elfutils-libelf elfutils-l
ibelf-devel gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers ksh libaio
libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-de
vel pdksh-5.2.14
2.创建相关用户和组
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
passwd oracle #设置oracle密码
3.设置相关系统变量
vi /home/oracle/.bash_profile
umask 022
export ORACLE_BASE=/u01/app
export ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=ORCL
export PATH=$PATH:HOME/bin:$ORACLE_HOME/bin
vi /etc/sysctl.conf
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
sysctl -p 不重启生效
vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
vi /etc/pam.d/login
session required pam_limits.so
vi /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
4.创建相关目录
mkdir -p /u01/app/
chown -R oracle:oinstall /u01/app/
5.解压软件包到 /u01目录
unzip linux.x64_11gR2_database_1of2.zip linux.x64_11gR2_database_2of2.zip
mv database/* /u01
6.上传或编辑自动响答文件 --附件
7.安装
chmod -R 775 /u01/app
chown -R oracle.oinstall /u01
su - oracle
cd /u01
./runInstaller -silent -force -responseFile /u01/response/db_install.rsp
centos 6 需要运行./runInstaller -silent -ignorePrereq -responseFile /u01/response/db_install.rsp
提示用root帐号运行两个sheel脚本表示安装完成
另开一个终端运行下面两个脚本
sh /u01/app/oracle/oraInventory/orainstRoot.sh
sh /u01/app/oracle/product/11.2.0/dbhome_1/root.sh
安装监听
$ORACLE_HOME/bin/netca -silent -responsefile /u01/response/netca.rsp
安装实列（运行会不断闪不管它直接输入两遍密码过一段时间会出现进度百分比）
$ORACLE_HOME/bin/dbca /silent /responsefile /u01/response/dbca.rsp
再安装个OEM
emca -config dbcontrol db -repos recreate
