RHEL5 安装 Oracle 11g

1、安装必要的rpm

yum install binutils compat-libstdc++ elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel glibc-headers gcc gcc-c++ libaio libaio-devel libgcc libstdc++ libstdc++-devel make numactl-devel sysstat

2、修改内核参数 limits

vim /etc/security/limits.conf

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft nproc 2047

oracle hard nproc 16384

3、修改内核参数 sysctl

vim /etc/sysctl.conf

kernel.shmmax = 4294967295

kernel.shmmni = 4096

kernel.shmall = 268435456

kernel.sem = 250 32000 100 128

fs.file-max = 6815744

net.ipv4.ip_local_port_range = 1024 65500

net.core.rmem_default = 4194304

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

fs.aio-max-nr = 1048576

4、让内核生效

/sbin/sysctl -p

5、添加用户和组

groupadd dba

groupadd oinstall

useradd -g oinstall -G dba oracle

6、修改profile

vim /etc/profile

在尾部加入

if [ $USER = "oracle" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

fi

7、建目录

mkdir -p /u01/app/oracle /u01/tmp

chown -R oracle:oinstall /u01/app/oracle /u01/tmp

chmod -R 775 /u01/app

chmod -R 777 /u01/tmp

8、编辑oracle用户配置文件

vim /home/oracle/.bash_profile

umask 022

TMP=/u01/tmp

TMPDIR=/u01/tmp

export TMP TMPDIR

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

export PATH=$ORACLE_HOME/bin:$PATH

export ORACLE_SID=orcl

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

export LANG=en_US

9、解压缩安装文件

tar zxvf oracle11gr2.tar.gz

chown -R oracle:oinstall database

10、开始安装

xhost +

su - oracle

./runInstaller

11、安装完毕执行

在root用户下执行

/u01/app/oracle/oraInventory/orainstRoot.sh

/u01/app/oracle/product/11.2.0/dbhome_1/root.sh
