在RockyLinux 9.3环境中采用RPM模式部署Oracle 19C

用途

在开发数据库系统时，可以验证功能是否与Oracle的表现一致，验证正确性和兼容性

限制

虚拟机安装，CPU 2*4 内存16G 磁盘100G
目标生产环境是RHEL 9.X，学习环境采用Rocky Linux 9.3
选择Oracle版本是长期支持版19C
只验证基础的功能，可以禁用CDB PDB
安装的Oracle只需要功能验证不用于生产环境，也不进行性能测试

查找资料

bing上查找资料，一般找到的安装Oracle的资料是CentOS 7.x,8.x，而9.x的比较少，找到：
- 基于RHEL9,ORACLE LINUX 9安装Oracle 19c 数据库
  可惜文中表示安装Oracle时需要安装库补丁，流程还是比较麻烦
- linux安装oracle19c完整版(图形+静默安装) 系统参数都是手工设置和通过界面设置，可以参考
直接查找官方文档
- Oracle Database Installation Guide 19c for Linux
  发现最新的19C没有要求安装补丁，并且支持RPM方式安装，过程非常简洁，尝试成功后总结，供大家参考。

准备环境

安装虚拟机的过程不再赘述，安装后需要做的准备工作如下：

关闭防火墙

#检查防火墙状态
systemctl status firewalld.service 
#关闭防火墙
systemctl stop firewalld.service 
#禁止开机启动防火墙
systemctl disable firewalld.service

关闭SELINUX

vi /etc/selinux/config

编辑内容：

#SELINUX=enforcing  #注释掉
SELINUX=disabled  #增加

存盘退出，下次重新启动后生效。如果想使配置立即生效，执行：

setenforce 0

配置域名
采用修改/etc/hostname的方式，重启后生效

vi /etc/hostname
oracle19c.learning.cn

配置域名解析

vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.154.19 oracle19c oracle19c.learning.cn

配置软件源
事先将rocky linux 9.3的ISO mount到/mnt/rocky9/

vi /etc/yum.repos.d/rocky.repo
[baseos]
name=Rocky Linux $releasever - BaseOS
baseurl=file:///mnt/rocky9/BaseOS/
gpgcheck=1
enabled=1
countme=1
metadata_expire=6h
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Rocky-9

[appstream]
name=Rocky Linux $releasever - AppStream
baseurl=file:///mnt/rocky9/AppStream/
gpgcheck=1
enabled=1
countme=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Rocky-9

准备Oracle RPM

预安装RPM：
访问Oracle Linux 9的软件源，如x86对应的是: https://yum.oracle.com/repo/OracleLinux/OL9/appstream/x86_64/，
找到对应Oracle 19c的预安装版本，如 oracle-database-preinstall-19c-1.0-1.el9.x86_64.rpm，下载该预安装rpm
Oracle 19C:
访问 Oracle下载页找到最新的19C版本，如
oracle-database-ee-19c-1.0-1.x86_64.rpm,然后下载到本地

Linux共享Windows目录
为了节省Linux的磁盘空间，直接在Linux中访问Windows下载的rpm

在Windows中共享保存rpm的文件夹，如名称为//192.168.154.1/Oracle
在Linux中链接Windows的共享

mkdir -p /mnt/oracle
mount -t cifs -o username=xxxx,password=yyyy //192.168.154.1/Oracle /mnt/oracle

请把"xxxx","yyyy"换成实际的用户名和密码

部署Oracle预安装RPM包

按官方文档，安装 Preinstallation RPM时会：

解析Oracle Grid Infrastructure和Oracle Database所需的依赖项,并自动下载和安装对应的RPM包
创建oracle用户，将其加入新创建的oraInventory (oinstall)和 OSDBA (dba)组中
按Oracle数据库预安装RPM程序的建议设置sysctl.conf、系统启动参数和驱动程序参数
设置硬和软资源限制 Linux进程资源访问限制
根据内核版本设置其他推荐参数
在Linux x86_64和Linux aarch64机器的内核中设置numa=off

dnf install -y /mnt/oracle/19c/oracle-database-preinstall-19c-1.0-1.el9.x86_64.rpm

检查进启动配置的变化

diff /boot/grub2/grub.cfg /boot/grub2/grub.cfg-oracle-database-preinstall-19c.orabackup
设置“numa=off transparent_hugepage=never”关闭了透明大页和numa
<   set kernelopts="root=/dev/mapper/rl-root ro crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M resume=/dev/mapper/rl-swap rd.lvm.lv=rl/root rd.lvm.lv=rl/swap rhgb quiet numa=off transparent_hugepage=never "

注意：修改了内核参数，需要重新启动

验证创建用户和用户组

groups oracle
oracle : oinstall dba oper backupdba dgdba kmdba racdba
id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54330(racdba)

从结果可见oracle属于7个组

验证透明大页是否关闭

cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
cat /sys/kernel/mm/transparent_hugepage/defrag
always defer defer+madvise [madvise] never

禁用CDB

vi /etc/init.d/oracledb_ORCLCDB-19c
...
export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1

export ORACLE_VERSION=19c
export ORACLE_SID=ORCLCDB

Database configuration completed successfully. The passwords were auto generated, you must change them by connecting to the database using 'sqlplus / as sysdba' as the oracle user.

可以查看详细一点儿的日志（输出了时间）

cat /opt/oracle/cfgtoollogs/dbca/ORCLCDB/ORCLCDB.log

本次初始化耗时6分钟，对比没有禁用CDB的一次实验，初始化耗时15分钟

修改oracle用户的环境变量

su - oracle
vi .bashrc
# 在原文件最后增加
umask 022
export TMP=/tmp
export TMPDIR=$TMP
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19c/dbhome_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export ORACLE_SID=ORCLCDB
export PATH=$ORACLE_HOME/bin:$PATH

小技巧：修改.bashrc 而不是.bash_profile的原因是可以支持非登录模式执行shell

验证基本功能

返回root重新以oracle用户执行

su - oracle
[oracle@oracle19c ~]$ sqlplus / as sysdba
SQL*Plus: Release 19.0.0.0.0 - Production on Thu Apr 18 17:23:03 2024

         A B
---------- ----------------
       200 天津
       100 beijing

重新启动系统后，发现服务不会自动重启，设置自动重启

采用RPM安装并没有设置自动重新启动Oracle的服务，运行 sqlplus / as sysdba 执行简单SQL报错，信息如下：

[oracle@oracle19c ~]$ sqlplus / as sysdba

SQL*Plus: Release 19.0.0.0.0 - Production on Thu Apr 18 22:59:25 2024

SQL> select * from t1 ;
select * from t1
*
ERROR at line 1:
ORA-01034: ORACLE not available
Process ID: 0
Session ID: 0 Serial number: 0

所以要手工增加自动重启的服务，此处主要参考ORACLE 19C 在centos 7的本地rpm包安装及调试，个别地方稍作修正

设置公共环境变量文件

vi /etc/sysconfig/ORCLCDB.oracledb
ORACLE_BASE=/opt/oracle
ORACLE_HOME=/opt/oracle/product/19c/dbhome_1
ORACLE_SID=ORCLCDB

创建监听服务

vi /usr/lib/systemd/system/ORCLCDB@lsnrctl.service
[Unit]
Description=Oracle Net Listener
After=syslog.target network.target

[Service]
Type=forking
EnvironmentFile=/etc/sysconfig/ORCLCDB.oracledb
ExecStart=/opt/oracle/product/19c/dbhome_1/bin/lsnrctl start
ExecStop=/opt/oracle/product/19c/dbhome_1/bin/lsnrctl stop
User=oracle

[Install]
WantedBy=multi-user.target

创建服务启动服务

vi /usr/lib/systemd/system/ORCLCDB@oracledb.service
[Unit]
Description=Oracle Database service
After=syslog.target network.target lsnrctl.service

[Service]
Type=forking
EnvironmentFile=/etc/sysconfig/ORCLCDB.oracledb

ExecStop=/opt/oracle/product/19c/dbhome_1/bin/dbshut $ORACLE_HOME
User=oracle

[Install]
WantedBy=multi-user.target

设置启动

vi /etc/oratab
...
#ORCLCDB:/opt/oracle/product/19c/dbhome_1:N
#将此处原来的N修改为Y
ORCLCDB:/opt/oracle/product/19c/dbhome_1:Y

激活服务
systemctl enable ORCLCDB@lsnrctl
systemctl enable ORCLCDB@oracledb
小技巧，先不忙着启动系统，先手工启动服务进行验证

systemctl start ORCLCDB@lsnrctl
systemctl start ORCLCDB@oracledb

如果有错误信息，则通过 systemctl status ORCLCDB@lsnrctl 分析问题

重启后检验服务状态

[root@oracle19c ansible]# netstat -tunlp | grep -E '1521|5500'
tcp6       0      0 :::5500                 :::*                    LISTEN      1090/tnslsnr

总结

本文的内容主要来自网络，但是经过了本人多次的验证和整理，剔除了一些不必要的环节，也为大家跳过了一些坑。如果有不足之处，请不吝指正，我一定及时修改更新。

1、RPM安装的限制

仅用于安装 Oracle 数据库软件，RAC不能这样安装，并且扣除preinstallation，安装rpm的难度与静默安装相当。
RPM 只能用于安装软件，而不能用于更新软件
无法控制软件安装的目录，即不一定能满足企业安装规范的目录约束
推荐仅用于实验环境，不要用于生产环境

2、一些坑（网上个别文档有些笔误）

19C 缺省在/etc/init.d/oracledb_ORCLCDB-19c 设置了字符集为AL32UTF8，无需在其他地方设置服务器字符集
/etc/hosts 一定要设置正确，但是无需删除127.0.0.1，::1 那两行
预安装RPM准备的内容见“验证预安装RPM的工作成果”部分，这些工作都不需要手工执行
仅仅功能验证的话不要启动CDB，否则连创建一个普通用户都要好几步操作

3、收获："验证预安装RPM的工作成果" 有一定的价值，可以验证网上其他RPM部署Oracle 19C的资料有哪些是重复的手工操作
