/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -g oinstall -G dba Oracle
passwd oracle
2. 创建安装录mkdir -p /u01/app/oracle/product/
chown -R oracle:oinstall /u01
chmod -R 777 /u01
3. 修改配置文件vi /etc/sysctl.conf

将CentOS release 5 (Final)修改成Red Hat Enterprise Linux AS release 5 (Taroon)
4. 重启计算机注意1:重启前必须配置好静态IP地址
注意2:重启后使用oracle用户登录
5. 解压缩安装文件注意1:用oracle用户解压安装包的ZIP文件;
注意2:两个压缩文件都解压到/u01下;
6. 安装Oracle 11g1、先切换到root用户,执行xhost +;
2、回到oracle用户,执行 runInstaller;
注意2:“步骤2/9”选择“仅安装数据库软件”;
注意3:“步骤9/12”如果“操作系统内核参数”有失败项,必须点“修补并再次检查”,按提示执行指定操作;
注意4:“步骤9/12”如果“程序包”有失败项,必须逐一安装;
注意5:安装完成后将补丁文件复制到/u01/app/oracle/product/11.2.0/dbhome_1/lib;
7. 修改用户配置注意1:执行vi ~/.bash_profile
注意2:修改后执行source ~/.bash_profile 让配置生效
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
ORACLE_OWNER=oracle; export ORACLE_OWNER
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1; export ORACLE_HOME
ORACLE_HOME_LISTNER=$ORACLE_HOME; export ORACLE_HOME_LISTNER
ORACLE_SID=ORACLE11G; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin; export PATH
8. 创建监听执行:/u01/app/oracle/product/11.2.0/dbhome_1/bin/netca
注意1:必须先设置你的静态IP地址;
注意2:必须修改配置文件vi /etc/resolv.conf ,将里面的IP改成你的静态IP;
注意3:创建下面的文件
vi /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
9. 创建数据库1、建议以root用户,执行chown -R oracle:oinstall /u01
2、建议以root用户,执行chmod -R 777 /u01
3、以oracle用户,执行:/u01/app/oracle/product/11.2.0/dbhome_1/bin/dbca
注意1:修改vi /etc/oratab
ORACLE11G:/u01/app/oracle/product/11.2.0/dbhome_1:Y
10. 测试安装结果
启动监听:
/u01/app/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start
启动数据库:
/u01/app/oracle/product/11.2.0/dbhome_1/bin/dbstart $ORACLE_HOME_LISTNER
启动管理平台:
/u01/app/oracle/product/11.2.0/dbhome_1/bin/emctl start dbconsole
