2.  验证需要的rpm包

rpm -q binutils compat-libcap1 compat-libstdc++- gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXext libXtst libX11 libXau libxcb libXi make sysstat

查询结果

binutils-2.27-.base.el7.x86_64
compat-libcap1-1.10-.el7.x86_64
package compat-libstdc++- is not installed
gcc-4.8.-.el7.x86_64
gcc-c++-4.8.-.el7.x86_64
glibc-2.17-.el7.x86_64
glibc-devel-2.17-.el7.x86_64
package ksh is not installed
libaio-0.3.-.el7.x86_64
package libaio-devel is not installed
libgcc-4.8.-.el7.x86_64
libstdc++-4.8.-.el7.x86_64
libstdc++-devel-4.8.-.el7.x86_64
libXext-1.3.-.el7.x86_64
libXtst-1.2.-.el7.x86_64
libX11-1.6.-.el7.x86_64
libXau-1.0.-2.1.el7.x86_64
libxcb-1.12-.el7.x86_64
libXi-1.7.-.el7.x86_64
make-3.82-.el7.x86_64
sysstat-10.1.-.el7.x86_64

安装没有安装的仨个包

yum install -y compat-libstdc++-
yum install -y libaio-devel
yum install -y ksh

3. 修改 系统配置

vi /etc/sysctl.conf
添加或修改下面参数

kernel.shmmax =
kernel.shmall = 10
kernel.shmmni =
kernel.sem =
net.core.rmem_default =
net.core.rmem_max =
net.core.wmem_default =
net.core.wmem_max = 1
net.ipv4.ip_local_port_range =
fs.file-max=70
fs.aio-max-nr=

修改

/etc/security/limits.conf

内容中添加如下配置。

oracle soft nproc
oracle hard nproc
oracle soft nofile
oracle hard nofile
oracle soft stack
oracle hard stack 

关闭防火墙 关闭selinux

添加用户

groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
修改密码
passwd oracle
创建oracle主目录
mkdir -p /u01/oracle
修改目录权限
chown -R oracle:oinstall /u01/oracle
chmod -R  /u01/oracle

修改环境变量. 在/etc/profile.d目录下新增一个oracle.sh 增加内容为

ORACLE_BASE=/u01/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/18.3./db_1; export ORACLE_HOME

ORACLE_SID=ora18c; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=/usr/sbin:$PATH; export PATH

PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

if [ $USER = "oracle" ]; then

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

ulimit -p 

ulimit -n 

else

ulimit -u  -n 

fi

fi

重新登录 验证 环境变量正常

echo $ORACLE_HOME
echo $ORACLE_SID

4. 上传linux 的安装包文件

xftp或者其他方式

解压缩 修改 安装权限

修改host 关闭防火墙 关闭 selinux 等步骤不在复述

5. 进入 GUI 图形化安装

注意 18c 与之前的不一样 需要将 安装文件放到 oracle_home 路径下来执行安装 没有再选择 oracle_home的选项了

mkdir -p $ORACLE_HOME
mv -R * $ORACLE_HOME

6. dbca 建库

tips 本次安装与其他的区别

注意加黑与红色字体部分

这次安装失败了三次 才想到官网找解决方案.

. 下载地址
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
. 本次安装应用端的速度很快好像更改了部分地方
官网地址:
https://docs.oracle.com/en/database/oracle/oracle-database/18/ladbi/running-oracle-universal-installer-to-install-oracle-database.html#GUID-DD4800E9-C651-4B08-A6AC-E5ECCC6512B9

. Log in as the Oracle installation owner user account (oracle) that you want to own the software binaries.
Download the Oracle Database installation image files (db_home.zip) to a directory of your choice. For example, you can download the image files to the /tmp directory.
Create the Oracle home directory and extract the image files that you have downloaded in to this Oracle home directory. For example:

$ mkdir -p /u01/app/oracle/product/18.0./dbhome_1
$ chgrp oinstall /u01/app/oracle/product/18.0./dbhome_1
$ cd /u01/app/oracle/product/18.0./dbhome_1
$ unzip -q /tmp/db_home.zip

Note:

. Oracle recommends that the Oracle home directory path you create is in compliance with the Oracle Optimal Flexible Architecture recommendations. Also, unzip the installation image files only in this Oracle home directory that you created.
From the Oracle home directory, run the runInstaller command to start the Oracle Database Setup Wizard.

$ cd /u01/app/oracle/product/18.0.0/dbhome_1
$ ./runInstaller
Note:

Run the runInstaller command from the Oracle home directory only. Do not run runInstaller from any other location.

. In the Select Configuration Option screen, select Create and configure a single instance database.

.Select your installation type.
Installation screens vary depending on the installation option you select. Respond to the configuration prompts as needed.

Note:

Click Help if you have any questions about the information you are asked to submit during installation.
