Oracle检查与安装操作内容

Oracle 安装：

检查安装包
rpm -q binutils compat-libstdc++ elfutils-libelf elfutils-libelf-devel elfutils-libelf-devel-static gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers kernel-headers ksh libaio libaio-devel libgcc libgomp libstdc++ libstdc++-devel make numactl-devel sysstat

vi /etc/sysctl.conf
添加参数

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 = 1048586 

改变当前系统内核参数值（让/etc/sysctl.conf立即生效）
# sysctl -p  

创建用户与组
groupadd -g 505 dba
groupadd -g 506 oinstall
useradd -g oinstall -G dba -s /bin/bash -u 555 oracle

passwd oracle

vi /etc/selinux/config
SELINUX=disabled

修改/etc/security/limits.conf文件
vim /etc/security/limits.conf
在打开的文件底部添加下面内容
oracle soft nproc 20470
oracle hard nproc 16384
oracle soft nofile 10240
oracle hard nofile 65536
oracle soft stack 10240  

mkdir -p /oracle/app/oracle/product/11.2/db_1
chown -R oracle:oinstall /oracle

vi .bash_profile
export PATH
export EDITOR=vi
export ORACLE_SID=redhat
export ORACLE_BASH=/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASH/product/11.2/db_1
