但是我们的DB SERVER无法连接外网，也就无法使用YUM连接ORACLE LINUX的更新服务器获得更新。从ORACLE LINUX 6.3开始可以从ORACLE LINUX安装光盘获得preinstall安装包。 1. 挂载光盘
[root@oem ~]# df -h
文件系统容量已用可用已用%% 挂载点
/dev/sda3 24G 8.4G 14G 38% / tmpfs 3.0G 100K 3.0G 1% /dev/shm /dev/sda1 97M 51M 42M 55% /boot
/dev/sr0 3.5G 3.5G 0 100% /media/OL6.4 x86_64 Disc 1 20130225
2. 修改yum repository配置
[root@oem tmp]# cd /etc/yum.repos.d/
[root@oem yum.repos.d]# cp public-yum-ol6.repo public-yum-ol6.repo.bak [root@oem yum.repos.d]# vi public-yum-ol6.repo
[ol6_dvd]
name=Oracle Linux DVD
baseurl=file:///media/OL6.4\\ x86_64\\ Disc\\ 1\\ 20130225/Server #gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=0 enabled=1
3. 安装oracle-rdbms-server-11gR2-preinstall包
[root@oem yum.repos.d]# yum update
[root@oem yum.repos.d]# yum install oracle-rdbms-server-11gR2-preinstall
手动配置
如果不使用preinstall包自动配置，就需要手工的做配置，具体的配置工作如下： 1. 修改/etc/sysctl.conf文件
Oracle需求的最小配置如下：
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
可以使用如下命令来查看某个参数值：
/sbin/sysctl -a | grep
在/etc/sysctl.conf文件里在添加或者修改如下内容：
fs.suid_dumpable = 1 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default=4194304 net.core.rmem_max=4194304 net.core.wmem_default=262144 net.core.wmem_max=1048586
修改完成之后执行如下命令使修改生效：
/sbin/sysctl –p
2. 在/etc/security/limits.conf文件里添加如下内容
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 4096 oracle hard nofile 65536 oracle soft stack 10240
3. 安装相关的RPM 包
# From Oracle Linux 6 DVD cd /media/cdrom/Server/Packages rpm -Uvh binutils-2*x86_64*
rpm -Uvh glibc-2*x86_64* nss-softokn-freebl-3*x86_64* rpm -Uvh glibc-2*i686* nss-softokn-freebl-3*i686* rpm -Uvh compat-libstdc++-33*x86_64* rpm -Uvh glibc-common-2*x86_64* rpm -Uvh glibc-devel-2*x86_64* rpm -Uvh glibc-devel-2*i686*
rpm -Uvh glibc-headers-2*x86_64* rpm -Uvh elfutils-libelf-0*x86_64* rpm -Uvh elfutils-libelf-devel-0*x86_64* rpm -Uvh gcc-4*x86_64* rpm -Uvh gcc-c++-4*x86_64* rpm -Uvh ksh-*x86_64* rpm -Uvh libaio-0*x86_64* rpm -Uvh libaio-devel-0*x86_64* rpm -Uvh libaio-0*i686* rpm -Uvh libaio-devel-0*i686* rpm -Uvh libgcc-4*x86_64* rpm -Uvh libgcc-4*i686* rpm -Uvh libstdc++-4*x86_64* rpm -Uvh libstdc++-4*i686*
rpm -Uvh libstdc++-devel-4*x86_64* rpm -Uvh make-3.81*x86_64* rpm -Uvh numactl-devel-2*x86_64* rpm -Uvh sysstat-9*x86_64*
rpm -Uvh compat-libstdc++-33*i686* rpm -Uvh compat-libcap* cd / eject
4. 创建groups和users
groupadd -g 501 oinstall groupadd -g 502 dba groupadd -g 503 oper groupadd -g 504 asmadmin groupadd -g 505 asmoper groupadd -g 506 asmdba
useradd -u 502 -g oinstall -G dba,asmdba,oper oracle passwd oracle
其它设置
1. 设置oracle用户密码
passwd oracle
2. 修改/etc/security/limits.d/90-nproc.conf
See MOS Note [ID 1487773.1]
# Change this
* soft nproc 1024
# To this * - nproc 16384
3. 禁用SELINUX
在/etc/selinux/config里设置：
SELINUX=disabled
修改这个参数需要重启系统才能生效。 4. 防火墙设置
To turn off the firewall do the following as the \
# service iptables stop # chkconfig iptables off
5. 创建ORACLE安装目录并赋权
mkdir -p /u01/app/oracle/product/11.2.0/db_1 chown -R oracle:oinstall /u01 chmod -R 775 /u01
6. 切换到oracle用户，并修改.bash_profile 文件
# Oracle Settings TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=oem.localdomain; export ORACLE_HOSTNAME ORACLE_UNQNAME=oem; export ORACLE_UNQNAME ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME ORACLE_SID=oem; export ORACLE_SID
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=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
3. 使用ORACLE用户，上传并解压ORACLE安装文件
将下载的ORACLE安装文件
