ORACLE 11.2.0.4 安装在 rhel6 上

. 修改host文件，添加本机的host记录
[root@RACDG ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.16    RACDG. 修改/etc/sysctl.conf文件，添加如下几行
[root@RACDG ~]# vi /etc/sysctl.conf
fs.suid_dumpable =
fs.aio-max-nr =
fs.file-max =
kernel.shmall =
kernel.shmmax =
kernel.shmmni =
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem =
net.ipv4.ip_local_port_range =
net.core.rmem_default=
net.core.rmem_max=
net.core.wmem_default=
net.core.wmem_max=

. 运行下面命令使其生效
[root@RACDG ~]# /sbin/sysctl -p

. 编辑/etc/security/limit.conf,添加下面几行
[root@RACDG ~]# vi /etc/security/limits.conf
oracle              soft    nproc
oracle              hard    nproc
oracle              soft    nofile
oracle              hard    nofile
oracle              soft    stack   

. 添加用户和组，以及添加oracle用户密码：
[root@RACDG ~]# groupadd -g  oinstall
[root@RACDG ~]# groupadd -g  dba
[root@RACDG ~]# groupadd -g  oper
[root@RACDG ~]# groupadd -g  asmadmin
[root@RACDG ~]# groupadd -g  asmdba
[root@RACDG ~]# groupadd -g  asmoper
[root@RACDG ~]# useradd -u  -g oinstall -G dba,asmdba,oper oracle
[root@RACDG ~]# passwd oracle

. 修改/etc/security/limits.d/-nproc.conf,做如下修改：
[root@RACDG ~]# vi /etc/security/limits.d/-nproc.conf
# Change this
*          soft    nproc    

# To this
* - nproc 

. 创建目录：
[root@RACDG ~]# mkdir -p /u01/app/oracle/product/11.2./db_1
[root@RACDG ~]# chown -R oracle:oinstall /u01
[root@RACDG ~]# chmod -R  /u01

.修改环境变量，添加如下几行：
[root@RACDG ~]# su - oracle
[oracle@RACDG ~]$ vi .bash_profile 

ORACLE_HOSTNAME=RACDG; export ORACLE_HOSTNAME
ORACLE_UNQNAME=orcl; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2./db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID

PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH

. 配置yum源：
[root@RACDG ~]# mkdir /mnt/rhel6
[root@RACDG ~]# mount /dev/cdrom /mnt/rhel6/
mount: block device /dev/sr0 is write-protected, mounting read-only
. 修改配置文件如下：
[root@RACDG ~]# vi /etc/yum.repos.d/rhel-source.repo
[rhel-source]
name=Rhel-Source
baseurl=file:///mnt/rhel6
enabled=
gpgcheck=

. 安装依赖包：
[root@RACDG ~]# yum install -y binutils compat-libcap1 compat-libstdc++ gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel sysstat make elfutils-libelf-devel compat-libstdc++--3.2.
Complete!

. 创建临时路径，将安装包上传到该路径下面，并解压该安装包
[root@RACDG ~]# mkdir /tmp/orasoft
[root@RACDG ~]# cd /tmp/orasoft/
[root@RACDG orasoft]# unzip p13390677_112040_Linux-x86-64_1of7.zip
[root@RACDG orasoft]# unzip p13390677_112040_Linux-x86-64_2of7.zip  

. 解压完成之后，可以看到生成了database文件夹
[root@RACDG orasoft]# ls
database  pdksh-5.2.-.el5_8..i386.rpm

. 利用Xmanager中的Xmanager-Passive进行图形化安装
[root@RACDG orasoft]# export DISPLAY=192.168.56.1:0.0
[root@RACDG orasoft]# xhost +
[root@RACDG orasoft]# su - oracle
[oracle@RACDG ~]$ cd /tmp/orasoft/database/
[oracle@RACDG database]$ ./runInstaller

. 进行网络配置
[oracle@RACDG database]$ netca

. 进行数据库安装
[oracle@RACDG database]$ dbca
