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

 

• 创建目录：

# 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'

export EDITOR=vi

export LANG=C

• 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
