实战：如何正确在LINUX8.0上安装Oracle 11.2.0.4

写这个测试的主要原因是前两天群里大佬们一直在讨论如何在REDHAT8.0上安装ORACLE 11G，我还好奇了，现在一般不是都用7.9来跑11G么？？

沟通一下才了解redhat 7快要停保了，正规的企业为了避免以后的问题，都考虑迁移到新版本的系统上。

关于红帽7的生命周期，又查询了一下，发现还能挺几年。

我这目前所处的客户环境还比较落后，要么都切到国产化了，都是一些小应用，那咱也得学啊！

于的查阅了相关的官方文档、BLOG确认11G确实是支持在linux8.0上运行。

汇总了这么一篇，写的有问题欢迎大家一起指正。有需要安装介质的可以添加我的微信公众号（见文末），回复oracle11gonlinx8获取文章内相关软件下载地址

也欢迎大家入jiekexu dba技术交流群一起讨论数据库问题，群里成员每天都积极发言、活跃，欢迎添加会长微信入群，加入著名数据库势力 青学会  @。@

1、关于版本认证

目前在MOS上查证，oracle database 11.2.0.4己经通过oracle linux8的认证

同样11GR2的官方文档也进行了相应的更新，增了关于OEL8以及RHEL8的说明，支持11.2.0.4数据库，但是8.2以后的系统不支持11.2.0.4的GI，如果想要实现高可用，需要安装19C的GI

2、硬件要求

内存要求是最小1G，建议2G或以上

SWAP要求如下配置

RAM	Swap Space
Between 1 GB and 2 GB	1.5 times the size of the RAM
Between 2 GB and 16 GB	Equal to the size of the RAM
More than 16 GB	16 GB

关于存储空间遵从11GR2官方手册的要求

至少要有1G以上的/tmp空间

至少4.4G的空间用来安装database软件

至少1.7G的空间还创建数据库

文件系统可以是EXT2/EXT3/EXT4/XFS等(see Note:236826.1 for further information)

3、关于LINUX8.0认证的操作系统

Kernel requirements

The following kernels are supported:

Oracle Linux 8.2 with the Unbreakable Enterprise Kernel 6: 5.4.17-2136.302.7.2.1.el8_5.x86_64 or later    

Oracle Linux 8.2 with the Red Hat Compatible Kernel: 4.18.0-348.12.2.el8_5.x86_64 or later    

Red Hat Enterprise Linux 8.2: 4.18.0-348.12.2.el8_5.x86_64 or later

Runlevel : 3 or 5

4、安装oracle

4.1、LINUX系统安装

我这里使用了oracle linux 8.9

系统安装的时候，选择最小安装，勾选了一些常用的工具和开发包。

安装完，查看当前系统版本

[root@oracle ~]# uname -a
Linux oracle 5.15.0-200.131.27.el8uek.x86_64 #2 SMP Wed Oct 4 22:19:10 PDT 2023 x86_64 x86_64 x86_64 GNU/Linux
[root@oracle ~]# cat /etc/oracle-release
Oracle Linux Server release 8.9

4.2、配置主机名

hostnamectl set-hostname oracle
echo "192.168.56.200 oracle" >>/etc/hosts

4.3、创建用户、参数配置

#create user
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/groupadd oper
/usr/sbin/useradd -g oinstall -G dba,oper oracle
echo "oracle" | passwd --stdin oracle
 
#change system parameter 
cp /etc/sysctl.conf /etc/sysctl.conf.bak
echo "#oracle" >> /etc/sysctl.conf
echo "kernel.shmmni = 4096" >> /etc/sysctl.conf
echo "fs.aio-max-nr = 1048576" >> /etc/sysctl.conf
echo "fs.file-max = 6815744" >> /etc/sysctl.conf
echo "kernel.sem = 250 32000 100 128" >> /etc/sysctl.conf
echo "net.ipv4.ip_local_port_range = 9000 65500" >> /etc/sysctl.conf
echo "net.core.rmem_default = 262144" >> /etc/sysctl.conf
echo "net.core.rmem_max = 4194304" >> /etc/sysctl.conf
echo "net.core.wmem_default = 262144" >> /etc/sysctl.conf
echo "net.core.wmem_max = 1048586" >> /etc/sysctl.conf
echo "vm.swappiness = 10" >> /etc/sysctl.conf
echo "kernel.shmmax= $(free|grep Mem |awk '{print int($2*1024*0.85)}')" >> /etc/sysctl.conf
echo "kernel.shmall = $(free|grep Mem |awk '{print int(($2*1024*0.85)/4096)}')" >> /etc/sysctl.conf
echo "vm.nr_hugepages = $(free -m|grep Mem |awk '{print int(($2*0.8*0.8)/2)}')" >> /etc/sysctl.conf
free -m
sysctl -p
echo "#oracle" >> /etc/security/limits.conf
echo "oracle soft nproc 2047" >> /etc/security/limits.conf
echo "oracle hard nproc 16384" >> /etc/security/limits.conf
echo "oracle soft nofile 1024" >> /etc/security/limits.conf
echo "oracle hard nofile 65536" >> /etc/security/limits.conf
echo "* soft memlock $(free |grep Mem|awk '{print int($2*0.90*1024)}')" >> /etc/security/limits.conf
echo "* hard memlock $(free |grep Mem|awk '{print int($2*0.90*1024)}')" >> /etc/security/limits.conf
#add oracle profile
cat >> /etc/profile <

4.4、禁用Transparent HugePages

cd /etc/default/

cp grub grub.bak

修改grub文件内容

GRUB_CMDLINE_LINUX="crashkernel=auto resume=/dev/mapper/ol-swap rd.lvm.lv=ol/root rd.lvm.lv=ol/swap rhgb quiet"

改为

GRUB_CMDLINE_LINUX="crashkernel=auto resume=/dev/mapper/ol-swap rd.lvm.lv=ol/root rd.lvm.lv=ol/swap rhgb quiet transparent_hugepage=never"

此处有差异

On BIOS-based machines（安装系统时使用传统 BIOS的改法）:

grub2-mkconfig -o /boot/grub2/grub.cfg

On UEFI-based machines（安装系统时使用UEFI-BIOS时的改法）:

grub2-mkconfig -o/boot/efi/EFI/redhat/grub.cfg

生成之后，重启服务器再检查

以下为输出

[root@oracle ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
[root@oracle ~]# cd /etc/default/
[root@oracle default]# cp grub grub.bak

4.5、创建目录，上传软件

mkdir /soft
chmod -R 777 /soft/--上传软件包到/soft目录下--包括OPATCH：p6880880_112000_Linux-x86-64--补丁包：p33477185_112040_Linux-x86-64、p33991024_11204220118_Generic--DB安装包：p13390677_112040_Linux-x86-64_1of7、p13390677_112040_Linux-x86-64_2of7
mkdir -p /u01
chow -R oracle:oinstall /u01

4.6、关闭SELINUX和防火墙

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
setenforce 0
systemctl disable firewalld && systemctl stop firewalld

4.7、配置YUM源

挂载系统安装介质ISO

mount /dev/cdrom /mnt
rm -rf /etc/yum.repos.d/*.repo
cat >/etc/yum.repos.d/local.repo<

4.8、安装软件包

dnf install bc binutils compat-openssl10 elfutils-libelf glibc glibc-devel ksh libaio libaio-devel libXrender libX11 libXau libXi libXtst libgcc libnsl libstdc++ libxcb libibverbs make policycoreutils policycoreutils-python-utils smartmontools sysstat -y

4.9、配置用户环境变量

cat >> /home/oracle/.bash_profile <

4.10、解压DB软件

su - oracle
cd /soft
unzip p13390677_112040_Linux-x86-64_1of7.zip
unzip p13390677_112040_Linux-x86-64_2of7.zip

4.11、创建静默安装文件

cat >> /soft/db_install.rsp <

4.12、创建oraInst.loc文件

以下以root用户执行

cat >> /etc/oraInst.loc <

4.13、开始安装

采用静默安装

su - oracle
cd /soft/database
./runInstaller -silent -noconfig -ignorePrereq -responseFile /soft/db_install.rsp

以下显示过程

[oracle@oracle database]$ ./runInstaller -silent -noconfig -ignorePrereq -responseFile /soft/db_install.rsp

Successfully Setup Software.

之所以不选择图形安装，是因为这个安装过程中会报好多错误需要你手动点，这可能会劝退很多小伙伴

其实看了官方文档，多数是己知BUG，安装的过程中只能忽略，安装完再打补丁修复

我举几个例子：

Bug 33830284

When you install Oracle Database on Oracle Linux 8.2, the Cluster Verification Utility (CVU) reports compat-libstdc++-33-3.2.3, and pdksh-5.2.14 missing errors.

Workaround:

In the Perform Prerequisites Checks screen, for the above errors, select Ignore All, and click Install to continue with the installation.

Ignore any linking errors during the installation. <<<-------------MOS上建议直接忽略接下来的所有错误

Bug 19375887

Backup and edit the $ORACLE_HOME/sysman/lib/ins_emagent.mk file.

In the ins_emagent.mk file, change $(MK_EMAGENT_NMECTL) to $(MK_EMAGENT_NMECTL) -lnnz11.

In the installer, click Retry to complete the installation.

测试没用，还是直接continue

后续还有好几个ins的失败，选择全部continue

4.14、解压opatch安装补丁

这一章节都是使用oracle执行

先替换opatch,然后安装补丁33477185

su - oracle
cd $ORACLE_HOME
mv OPatch/ OPatch.old
cd /soft
unzip p6880880_112000_Linux-x86-64.zip
unzip p33477185_112040_Linux-x86-64.zip
mv OPatch/ $ORACLE_HOME/
opatch version
cd /soft/33477185
opatch apply

以下为输出，结果太长截图部分

再安装补丁33991024

cd /soft
unzip p33991024_11204220118_Generic.zip
cd 33991024/
opatch apply

以下为输出

最后，按补丁要标relink

[oracle@oracle 33991024]$ $ORACLE_HOME/bin/relink all

OPatch succeeded.

之后就可以正常使用，netca DBCA创建数据库即可

安装完之后，官方文档还有几句
