RHEL6 Configuration

Step1：Setup hostname & Close the selinux

[root@jmilkfan Desktop]# hostname 
jmilk.fan.com

vim /etc/sysconfig/selinux

SELINUX=permissive

立即生效关闭防火墙

[root@jmilk ~]# setenforce 0

Step2：Setup Static IP
vim /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0C:29:F2:C6:8D"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="f129f448-7aa6-43bd-bf68-699774b0a553"
IPADDR=192.168.1.222
NETMASK=255.255.255.0

Re-start network service

Step3：Edit /etc/hosts
vim /etc/hosts

192.168.1.222 jmilk.fan.com

Step4：创建用户和用户组

/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
useradd -g oinstall -G dba oracle
(echo fanguiju;echo fanguiju) | passwd --stdin oracle

Step5：创建安装路径目录

[root@jmilk Desktop]# mkdir -p /u01/app/oracle
[root@jmilk Desktop]# chown -R oracle:oinstall /u01/app/oracle
[root@jmilk Desktop]# chmod -R 775 /u01/app/oracle
[root@jmilk Desktop]# ll -d /u01/app/oracle/
drwxrwxr-x. 2 oracle oinstall 4096 May 24 22:22 /u01/app/oracle/

Step6：配置内核参数
vim /etc/sysctl.conf

# Controls the maximum shared segment size, in bytes
kernel.shmmax = 2147483648

# Controls the maximum number of shared memory segments, in pages
kernel.shmall = 2097152
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576

刷新配置

sysctl-p

Step7：修改limits.conf配置文件

oraclesoft    nproc   2047
oracle           hard    nproc   16384
oracle           soft    nofile  1024
oracle           hard    nofile  65536

Step8：修改login配置文件
vim /etc/pam.d/login

#Use for Oracle
session    required     pam_limits.so

Step9：配置Oracle用户环境变量

[root@jmilk Desktop]# su - oracle

vim .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 ORACLE_SID=gsp
export ORACLE_BASE=/u01/app/oracle                     #ORACLE_BASE是最重要的，代表Oracle的安装路径
export ORACLE_HOME=$ORACLE_BASE/product/dbhome_1       
export ORACLE_OWNER=oracle
export PATH=$ORACLE_HOME/bin:$PATH
umask 022

刷新用户环境变量

source .bash_profile
DISPLAY=local_host:0.0 ; export DISPLAY

Step10：修改/etc/profile文件

if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
fi

Update JDK

卸载OpenJDK并更新JDK，下载JDK1.8 点这里

Step1：rpm安装JDK1.8

[root@jmilk Desktop]#  rpm -qa |grep java 
tzdata-java-2012j-1.el6.noarch
java-1.7.0-openjdk-1.7.0.9-2.3.4.1.el6_3.x86_64
java-1.6.0-openjdk-1.6.0.0-1.50.1.11.5.el6_3.x86_64
[root@jmilk Desktop]# rpm -e --nodeps tzdata-java-2012j-1.el6.noarch
[root@jmilk Desktop]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.9-2.3.4.1.el6_3.x86_64
[root@jmilk Desktop]# rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.50.1.11.5.el6_3.x86_64
[root@jmilk Desktop]# cd /opt/jdk1.8/
[root@jmilk jdk1.8]# ls

配置JDK环境变量
vim /etc/profile

JAVA_HOME=/usr/java/jdk1.8.0_91
JRE_HOME=/usr/java/jdk1.8.0_91/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export JAVA_HOME JRE_HOME PATH CLASSPATH 

加载配置

source /etc/profile
alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_91/bin/java 1
alternatives --install /usr/bin/javac javac /usr/java/jdk1.8.0_91/bin/javac 1
alternatives --config java
alternatives --config javac

配置Oracle安装环境

硬件检测

官方安装文档对硬件额要求：

#At least 512 MB of physical RAM
内存要大于512M
#The following table describes the relationship between installed RAM and the configured swap space requirement.
内存和Swap分区的大小要求

RAM	Swap Space
Up to 512 MB	2 times the size of RAM
Between 1024 MB and 2048 MB	1.5 times the size of RAM
Between 2049 MB and 8192 MB	Equal to the size of RAM
More than 8192 MB	0.75 times the size of RAM

#400 MB of disk space in the /tmp directory
必须被/tmp目录留下400MB
#Between 1.5 GB and 3.5 GB of disk space for the Oracle software, depending on the installation type
需要预留1.5G到3.5G的磁盘空间
#1.2 GB of disk space for a preconfigured database that uses file system storage

Step1：查看内存大小

[root@jmilk Desktop]# grep MemTotal /proc/meminfo
MemTotal:        8046852 kB

Step2：查看Swap空间大小

[root@jmilk Desktop]# grep SwapTotal /proc/meminfo
SwapTotal:       4194296 kB

Step3：查看/tmp分区的大小

[root@jmilk Desktop]# df -m /tmp
Filesystem           1M-blocks      Used Available Use% Mounted on
/dev/sda3                36088      5907     28349  18% /

软件检测

因为在安装Oracle的过程中，要重新编译安装许多内置软件程序。所以Oracle的安装环境需要软件依赖包的支撑，Oracle官方安装文档提供了需要预安装的软件包列表：

• Red Hat Enterprise Linux 4.0:
  
  • binutils-2.15.92.0.2-10.EL4
  • compat-db-4.1.25-9
  • control-center-2.8.0-12
  • gcc-3.4.3-9.EL4
  • gcc-c++-3.4.3-9.EL4
  • glibc-2.3.4-2
  • glibc-common-2.3.4-2
  • gnome-libs-1.4.1.2.90-44.1
  • libstdc++-3.4.3-9.EL4
  • libstdc++-devel-3.4.3-9.EL4
  • make-3.80-5
  • pdksh-5.2.14-30
  • sysstat-5.0.5-1
  • xscreensaver-4.18-5.rhel4.2

注意：因为Oracle 10g官方推荐在RHEL4上安装，所以提供的软件包列表版本会偏低。我们在RHEL6中安装Oracle时，无论是检测还是安装的过程中都需要忽略软件包的版本问题。

rpm-q gcc make binutils openmotif setarch compat-db compat-gcc compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel

Step1：配置光盘YUM源
vim /etc/yum.repos.d/local.repo

[local]
name=local
baseurl=file:///media
enabled=1
gpgcheck=0

Step2：安装依赖软件包

yuminstall -y gcc-*
yum install -y binutils-*
yum install -y openmotif-*
yum install -y compat-db-*
yum install -y compat-gcc-*
yum install -y compat-gcc-c++-*
yum install -y setarch*
yum install -y compat-libstdc++*
yum install -y compat-libstdc++-devel*
yum install -y compat-libstdc++-33
yum install -y glibc*
yum install -y libstdc++*
yum install -y make*
yum install libXt.i686
yum install libXtst.i686
yum install binutils-2.* compat-libstdc++-33* elfutils-libelf-0.* elfutils-libelf-devel-* gcc-4.* gcc-c++-4.* glibc-2.* glibc-common-2.* glibc-devel-2.* glibc-headers-2.* ksh-2* libaio-0.* libaio-devel-0.* libgcc-4.* libstdc++-4.* libstdc++-devel-4.* make-3.* sysstat-7.* unixODBC-2.* unixODBC-devel-2.* pdksh*
yum install -y compat-gcc* compat-glibc* compat-libstd*
rpm -ivh --force libXp-1.0.0-15.1.el6.x86_64.rpm   #需要到Package目录下强制安装

编辑配置文件

Step1：配置系统版本
注意：因为Oracle默认只支持到RHEL4，所以我们需要修改系统版本来欺骗Oracle安装程序。
vim /etc/redhat-release

Red Hat Enterprise Linux Server release 4.0 (Santiago)

安装Oracle Database

Step1：解压Oracle Database安装软件

mkdir /mnt/hgfs/DataBase/
cd /mnt/hgfs/DataBase/
gunzip10201_database_linux_x86_64.cpio.gz
cpio -idmv < 10201_database_linux_x86_64.cpio

Step2：重启并使用oracle用户账号登陆
注意：不能使用su - oracle

Step3：执行安装脚本

[oracle@jmilk Desktop]$ cd /mnt/hgfs/Database/database/
[oracle@jmilk database]$ ./runInstaller 

注意：安装过程中如果报“ORA-27125:unable to create shared memory segment”这个错误，一般原因是操作系统用户权限不足的问题，可以通过下面的方式来解决

id oracle
echo vm.hugetlb_shm_group=501 > /etc/sysctl.conf
sysctl -p

输入Oracle最高级管理员orcl的密码

忽略这个错误，点击Continue

完成安装
