二、安装部署环境

2.1、安装部署环境规划

环境介绍 版本
主机环境 CentOS Linux release 7.4.1708 (Core) 
oracle环境 oracle19c
oracle实例名称 orcl19c（普通数据库：如同11gr2创建的数据库）
orclpdb19c（容器数据库：pdb）
服务器IP 172.21.109.122

2.2、操作系统环境准备

1、准备好服务器，虚拟机或物理机并安装后操作系统。


2、设置主机名和/etc/hosts文件

[root@manager oracle]# hostname
manager


[root@manager oracle]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.21.209.122 manager oracle

3、关闭防火墙和selinux

关闭防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service

关闭selinux
[root@manager oracle]# cat /etc/selinux/config 

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled                                            #修改为disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

2.3、配置本地yum源

下载并上传ISO镜像文件
[root@manager data]# pwd 
/data
[root@manager data]# ll|grep *.iso
-rw-r--r--  1 root    root    4588568576 May 19 14:30 CentOS-7.6-x86_64-DVD-1810.iso

挂载镜像文件
[root@manager data]# mkdir  centos76
[root@manager data]# mount -o loop /data/CentOS-7.6-x86_64-DVD-1810.iso  /data/centos76/
mount: /dev/loop0 is write-protected, mounting read-only

[root@manager data]# df -h

/dev/loop0      4.3G  4.3G     0 100% /data/centos76
[root@manager data]# 


编辑repo文件
vi redhat-base.repo

[local]
name=Red Hat Enterprise Linux 6.7
baseurl=file:///mnt
enabled=1
gpgcheck=1
gpgkey=file:///mnt/RPM-GPG-KEY-redhat-release

三、操作系统环境准备

3.1、创建组和用户

/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

3.2、修改用户oracle密码

passwd oracle

3.3、创建工作的目录，然后赋予相应的权限。

在root用户下执行命令

mkdir -p /u01/app/oracle/product/19.2.0/db_1
chown -R oracle:oinstall /u01/
chmod -R 775 /u01/

3.4、配置Oracle的环境变量

切换到oracle用户
su - oracle

打开环境变量文件，并输入一下内容
vi .bash_profile

ORACLE_SID=orcl19c;export ORACLE_SID
ORACLE_UNQNAME=orcl19c;export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/19.2.0/db_1; export ORACLE_HOME

NLS_DATE_FORMAT="YYYY:MM:DDHH24:MI:SS"; export NLS_DATE_FORMAT
NLS_LANG=american_america.ZHS16GBK; export NLS_LANG
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
ORA_NLS11=$ORACLE_HOME/nls/data; export ORA_NLS11
PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORA_CRS_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JRE
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export CLASSPATH

THREADS_FLAG=native; export THREADS_FLAG
export TEMP=/tmp
export TMPDIR=/tmp
umask 022

3.5、修改内核参数

首先退出到root用户，然后输入一下内容

vi /etc/sysctl.conf


fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
kernel.panic_on_oops = 1
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

执行如下命令，使生效。
sysctl --system

3.6、安装oracle依赖的包

yum install bc gcc gcc-c++ binutils compat-libcap1 compat-libstdc++ dtrace-modules dtrace-modules-headers 
dtrace-modules-provider-headers dtrace-utils elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc glibc-devel 
ksh libaio libaio-devel libdtrace-ctf-devel libX11 libXau libXi libXtst libXrender libXrender-devel libgcc librdmacm-devel 
libstdc++ libstdc++-devel libxcb make smartmontools sysstat 

注意：需要配置有本地yum源。

4、安装oracle19c数据库系统

4.1、上传下载的软件包并解压

上传文件到指定目录下
[root@manager oracle]# pwd
/data/oracle
[root@manager oracle]# ll
total 2988000
-rw-r--r-- 1 root root 3059705302 May  8 15:38 LINUX.X64_193000_db_home.zip


然后解压压缩包，如果没解压工具，则安装。
yum -y install zip unzip

su - oracle
unzip /data/oracle/LINUX.X64_193000_db_home.zip -d  /u01/app/oracle/product/19.2.0/db_1/  #-d表示解压到指定目录下。

4.2、图形化安装Oracle数据库

1、oracle登陆系统

登陆到操作系统图形化界面，切换到Oracle用户
[oracle@localhost db_1]$ export DISPLAY=:0
[oracle@localhost db_1]$ LANG=en_US ./runInstaller

注意：

linux7操作系统图形化安装Oracle软件时，需要设置DISPLAY环境变量，如果不设置DISPLAY环境变量，在启动图形界面的时候，很可能会遇到下面的错误。
[oracle@manager db_1]$ ./runInstaller 
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.

No X11 DISPLAY variable was set, but this program performed an operation which requires it.

处理方法：root用户查看display 环境变量
查看：xdpyinfo | head
设置：export DISPLAY=:0

2、执行安装脚本，安装oracle19c数据库。

5、登陆数据库

oracle19c刚安装完成后，登陆数据库时，是一个空数据库（无监听程序和进程，因此需要创建数据库和监听程序）。

1、登陆数据库

切换到oracle用户
[root@manager ~]# su - oracle
Last login: Thu May 20 12:24:52 CST 2021 on pts/1
[oracle@manager ~]$ 
加载环境变量
[oracle@manager ~]$ source .bash_profile 

以dba角色登陆数据库。
[oracle@manager ~]$ sqlplus / as sysdba

SQL*Plus: Release 19.0.0.0.0 - Production on Thu May 20 12:27:41 2021
Version 19.3.0.0.0

Copyright (c) 1982, 2019, Oracle.  All rights reserved.

Connected to an idle instance.

TNS-12541: TNS:no listener
 TNS-12560: TNS:protocol adapter error
  TNS-00511: No listener
   Linux Error: 111: Connection refused

3、查看oracle的进程，

[oracle@manager ~]$ ps -ef|grep orcl
oracle   14788 14372  0 12:32 pts/1    00:00:00 grep --color=auto orcl
[oracle@manager ~]$

4、查看监听端口

[oracle@manager ~]$ netstat  -lntp|grep orcl
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
[oracle@manager ~]$

6、创建数据库

1、以oracle用户登录数据库，命令行输入dbca，弹出会话框。
