1. 操作系统版本
[root@master ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.3 (Maipo)
2. 操作系统包要求
[root@master yum.repos.d]# vi yum.sh
yum install -y binutils-*
yum install -y compat-libcap1-*
yum install -y compat-libstdc++-*
yum install -y gcc-*
yum install -y gcc-c++-*
yum install -y glibc-*
yum install -y glibc-devel-*
yum install -y ksh
yum install -y libaio-*
yum install -y libaio-devel-*
yum install -y libgcc-*
yum install -y libstdc++-*
yum install -y libstdc++-devel-
yum install -y libXi-*
yum install -y libXtst-*
yum install -y make-*
yum install -y sysstat-*
yum install -y unixODBC*
chmod +x yum.sh
3. 操作系统内核配置
vi /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967296
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
保存退出编辑器，执行以下命令使设置生效
# sysctl -p
4. 操作系统资源配置
vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32786
5. 操作系统SELINUX配置
/etc/selinux/config：
SELINUX=disabled
6. 操作系统防火墙配置
systemctl stop firewalld
systemctl disable firewalld.service
7. 创建用户
[root@master ~]# groupadd oinstall
[root@master ~]# groupadd dba
[root@master ~]# useradd -g oinstall -G dba oracle
[root@master ~]# id oracle
uid=1000(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)
[root@master ~]# passwd oracle
8. 创建目录
创建/u01
# lvcreate -L 20G -n oracle_lv datavg
# mkfs.ext4 /dev/ datavg/oracle_lv
# cd /
# mkdir -p /u01/app/oracle
# mount /dev/ datavg/oracle_lv /u01
# chown -R oracle:oinstall /u01
修改/etc/fstab文件使创建目录重启自动挂载
vi /etc/fstab
/dev/mapper/datavg-oracle_lv /u01 ext4 defaults 1 1
9. 设置用户环境变量
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1
export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH
export ORACLE_SID=orcl
TEMP=/tmp
TMPDIR=/tmp
export PATH TEMP TMPDIR
10. 安装软件
11.安装数据库DBCA
