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
