第十天 Oracle安装前准备工作

确认root身份:

# id

硬件配置：

# grep MemTotal /proc/meminfo 内存

# grep SwapTotal /proc/meminfo 交换内存

# vi /etc/fstab（永久修改）

tmpfs /dev/shm tmpfs defaults,size=2G 0 0

# mount -o remount /dev/shm

临时修改

# mount -t tmpfs shmfs -o size=2g /dev/shm

# uname -m

# df -h

替代6 7 8 9步

# cd /media/OL6.4 x86_64 Disc 1 20130225/Packages/

# yum install oracle-rdbms-server-11gR2-preinstall //安装这个安装包会把其他的软件包一块安装并且修改内核参数环境设置

6. rpm检查并安装：

# cat /etc/oracle-release

# cat /etc/redhat-release

# uname -r

# rpm -qa | grep glibc

# yum install glibc

# yum install glibc.i686

创建用户：

# groupadd -g 1000 oinstall

# groupadd -g 1001 dba

# groupadd -g 1002 oper

# useradd -u 1000 -g oinstall -G dba,oper oracle

# passwd oracle

修改内核参数：

# vi /etc/sysctl.conf

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 = 1048576

# sysctl -p

修改资源限制：

# vi /etc/security/limits.conf

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft stack 10240

oracle hard stack 32768

# mkdir -p /u01/app/oracle

# chown -R oracle:oinstall /u01

# chmod -R 775 /u01

修改概要文件：

# vi ~oracle/.bash_profile

export ORACLE_SID=orcl

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export ORACLE_HOSTNAME=node1.test.com

export ORACLE_UNQNAME=orcl

export PATH=$PATH:$ORACLE_HOME/bin

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

export NLS_LANG=american_america.AL32UTF8

export NLS_DATE_FORMAT='yyyy-mm-dd hh24:mi:ss'

使用hosts文件解析主机名：

# hostname

node1.test.com

# vi /etc/hosts

192.168.0.1 node1.test.com node1

# ping node1

# ping node1.test.com
