# 清理缓存
yum clean all
# 建缓存
yum makecache
#安装epel源

#selinux修改后需要重启主机生效：
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

配置Hosts文件

cat <<EOF >>/etc/hosts
##OracleBegin##
##Public IP
192.168.129.191     oracle11g
##OracleEnd##
EOFhostnamectl set-hostname orcl

防火墙配置

systemctl stop firewalld
systemctl disable firewalld

配置ZeroConf

##关闭Zeroconf service的服务守护进程
systemctl stop avahi-daemon.socket
systemctl stop avahi-daemon.service
systemctl disable avahi-daemon.service
systemctl disable avahi-daemon.socket

##关闭NOZEROCONF

cat <<EOF >>/etc/sysconfig/network
#OracleBegin
NOZEROCONF=yes
#OracleEnd
EOF

关闭GRUB

sed -i 's/quiet/quiet transparent_hugepage=never numa=off/' /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg

配置系统参数文件

##配置系统参数
cat <<EOF >>/etc/sysctl.conf

net.core.wmem_default = 262144
net.core.wmem_max = 1048576
EOF##系统参数生效
sysctl -p

配置系统资源限制

cat <<EOF >>/etc/security/limits.conf

创建用户和组

/usr/sbin/groupadd -g 54321 oinstall
/usr/sbin/groupadd -g 54322 dba
/usr/sbin/groupadd -g 54323 oper/usr/sbin/useradd -u 54321 -g oinstall -G dba,oper oracle
echo oracle | passwd --stdin oracle

mkdir -p /u01/app/oraInventory
mkdir -p /u01/app/oracle/oradata
chown -R oracle:oinstall /u01/app
chmod -R 775 /u01/app

配置用户环境变量

cat <<EOF >>/home/oracle/.bash_profile

解压Oracle软件安装包

##需要按顺序解压1，2安装包：
cd /soft
unzip -q Linux-x86-64_1of2.zip
unzip -q Linux-x86-64_2of2.zip
##授权/soft给oracle读写权限
chown -R oracle:oinstall /soft

安装VNC软件

yum install -y tigervnc*su - oracle
vncserver
##输入密码export DISPLAY=192.168.129.191:1

连接VNC远程工具或者直接打开虚拟机图形化界面

##右键打开终端工具：
进入/soft/database开始安装Oracle软件：
su oracle
./runInstaller

之后按照提示进行操作

swap设置的太小。

#创建swap文件 bs的设置的值一般为内存的1.5倍以上 
swapoff -a rm /var/swap
dd if=/dev/zero of=/var/swap bs=1024 count=8000000
#需要更改swap文件的权限，确保只有root才可读
chmod 600 /var/swap
#告知系统将该文件用于swap
mkswap /var/swap
#开始使用该swap
swapon /var/swap
#使Swap文件永久生效,/etc/fstab加入配置
echo "/var/swap   swap    swap    sw  0   0" >> /etc/fstab
