在RockyLinux 9.3环境中采用RPM模式部署Oracle 19C

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

  1. 虚拟机安装,CPU 2*4 内存16G 磁盘100G
  2. 目标生产环境是RHEL 9.X,学习环境采用Rocky Linux 9.3
  3. 选择Oracle版本是长期支持版19C
  4. 只验证基础的功能,可以禁用CDB PDB
  5. 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

  1. 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:
  2. 直接查找官方文档

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:

  1. 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 
  1. 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 
  1. 配置域名
    采用修改/etc/hostname的方式,重启后生效
vi /etc/hostname
oracle19c.learning.cn
  1. 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
  1. 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
  1. 准备Oracle RPM
  1. 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:

  1. 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
  2. 创建oracle用户,将其加入新创建的oraInventory (oinstall)和 OSDBA (dba)组中
  3. 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
  4. 设置硬和软资源限制 Linux进程资源访问限制
  5. 根据内核版本设置其他推荐参数
  6. 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

注意:安装完成后重新启动系统,确认所有的系统参数已经应用

验证预安装RPM的工作成果(不是强迫症无需关注这一部分)

  1. 检查依赖项,执行命令
dnf repoquery --requires oracle-database-preinstall-19c-1.0-1.el9.x86_64.rpm
/bin/sh
/etc/redhat-release
/usr/bin/bash
bc
bind-utils
binutils
ethtool
glibc
glibc-devel
initscripts
ksh
libaio
libaio-devel
libgcc
libnsl
libstdc++
libstdc++-devel
make
module-init-tools
net-tools
nfs-utils
openssh-clients
pam
policycoreutils
policycoreutils-python-utils
procps
psmisc
smartmontools
sysstat
tar
unzip
util-linux-ng
xorg-x11-utils
xorg-x11-xauth

显示所有的依赖项,说明在部署预安装RPM过程中,检查3个文件和31个rpm的依赖关系

  1. 检查系统配置/etc/sysctl.conf 增加了内容
cat /etc/sysctl.conf
# oracle-database-preinstall-19c setting for fs.file-max is 6815744
fs.file-max = 6815744
# oracle-database-preinstall-19c setting for kernel.sem is '250 32000 100 128'
kernel.sem = 250 32000 100 128

kernel.shmmni = 4096
# oracle-database-preinstall-19c setting for kernel.shmall is 1073741824 on x86_64
kernel.shmall = 1073741824

kernel.shmmax = 4398046511104
# oracle-database-preinstall-19c setting for kernel.panic_on_oops is 1 per Orabug 19212317
kernel.panic_on_oops = 1
# oracle-database-preinstall-19c setting for net.core.rmem_default is 262144
net.core.rmem_default = 262144
# oracle-database-preinstall-19c setting for net.core.rmem_max is 4194304
net.core.rmem_max = 4194304
# oracle-database-preinstall-19c setting for net.core.wmem_default is 262144
net.core.wmem_default = 262144

net.core.wmem_max = 1048576
# oracle-database-preinstall-19c setting for net.ipv4.conf.all.rp_filter is 2
net.ipv4.conf.all.rp_filter = 2
# oracle-database-preinstall-19c setting for net.ipv4.conf.default.rp_filter is 2
net.ipv4.conf.default.rp_filter = 2
# oracle-database-preinstall-19c setting for fs.aio-max-nr is 1048576
fs.aio-max-nr = 1048576
# oracle-database-preinstall-19c setting for net.ipv4.ip_local_port_range is 9000 65500
net.ipv4.ip_local_port_range = 9000 65500

注: 原文件备份在/etc/sysctl.d/99-initial-sysctl.conf

  1. 检查系统配置/etc/sysconfig/network 增加了内容
cat /etc/sysconfig/network
# Created by anaconda
# oracle-database-preinstall-19c : Add NOZEROCONF=yes
NOZEROCONF=yes
  1. 检查进程资源配置
cat /etc/security/limits.d/oracle-database-preinstall-19c.conf
# oracle-database-preinstall-19c setting for nofile soft limit is 1024
oracle soft nofile 1024
# oracle-database-preinstall-19c setting for nofile hard limit is 65536
oracle hard nofile 65536
# oracle-database-preinstall-19c setting for nproc soft limit is 16384

# oracle-database-preinstall-19c setting for stack hard limit is 32768KB
oracle hard stack 32768
# oracle-database-preinstall-19c setting for memlock hard limit is maximum of 128GB on x86_64 or 3GB on x86 OR 90 % of RAM
oracle hard memlock 134217728
# oracle-database-preinstall-19c setting for memlock soft limit is maximum of 128GB on x86_64 or 3GB on x86 OR 90% of RAM
oracle soft memlock 134217728
# oracle-database-preinstall-19c setting for data soft limit is 'unlimited'
oracle soft data unlimited
# oracle-database-preinstall-19c setting for data hard limit is 'unlimited'
oracle hard data unlimited
  1. 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 "
---
> 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 "

注意:修改了内核参数,需要重新启动

  1. 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

  1. 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
  1. 也可以查看安装日志
cat /var/log/oracle-database-preinstall-19c/results/orakernel.log

修改oracle用户的环境变量

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

重新启动系统后,发现服务不会自动重启

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:

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

  • 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 
tcp6 0 0 :::1521 :::* 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

  1. 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。
  2. RPM 只能用于安装软件,而不能用于更新软件
  3. 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
  4. 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)

  1. 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
  2. /etc/hosts 一定要设置正确,但是无需删除127.0.0.1,::1 那两行
  3. 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
