RHEL5.4 64位 oracle11G 安装与卸载

1.配置系统内核参数

vi /etc/sysctl.conf

fs.aio-max-nr = 1048576
fs.file-max = 6815744

#kernel.shmall = 33554432
#kernel.shmmax = 68719476736
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128

vm.min_free_kbytes = 524288
vm.swappiness = 100


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

执行下面命令让内核参数立即生效

sysctl -p

2. SHELL 资源限制 /etc/security/limits.conf

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240

3.配置/etc/security/limits.conf，增加以下内容
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  1024
oracle              hard    nofile  65536
oracle              hard    stack   10240

4.创建oracle相关群组及用

groupadd -g 601 oinstall
groupadd -g 602 dba
useradd -g oinstall -G dba oracle
echo oracle | passwd oracle --stdin

5.创建安装目录并赋予oracle相应权限
mkdir -p /u01/app/oracle/product/11.2.0/db_1
mkdir -p /u01/app/oracle/oradata
chown -R oracle:oinstall /u01
chmod -R 775 /u01

6.配置oracle环境变量

su - oracle 
vi ~/.bash_profile

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH
export NLS_LANG="AMERICAN_AMERICA.AL32UTF8"
if [ $USER = "oracle" ]; then
  if [ $SHELL = "/bin/ksh" ]; then
    ulimit -p 16384
    ulimit -n 65536
  else
    ulimit -u 16384 -n 65536
  fi
fi
umask 022

执行source .bash_profile使环境变量生效

7.开始oracle11g安装

cd /home/oracle/database
./runInstaller

二、卸载

方法:手工删除文件办法

删除 /etc/ora*

删除/usr/local/bin/oraenv

删除/usr/local/bin/dbhome

删除/usr/local/bin/coraenv

删除$ORACLE_BASE/*
