一、认证检查

根据文档Certification Information for Oracle Database on Linux x86-64 (Doc ID 1304727.2) ，11.2.0.4针对Oracle Linux 8 and Red Hat Enterprise Linux 8新增了认证。

二、操作系统要求

参考文档：
Supported Red Hat Enterprise Linux 8 Distributions for x86-64 for Oracle Database

安装环境检查：

[root@linux8 ~]# uname -a 
Linux linux8 4.18.0-240.el8.x86_64 #1 SMP Wed Sep 23 05:13:10 EDT 2020 x86_64 x86_64 x86_64 GNU/Linux
[root@linux8 ~]# cat /etc/redhat-release

192.168.31.83 linux8
[root@linux8 ~]#

三、操作系统配置

其余操作系统级别必要的配置请参考官方文档，这里不再赘述。

3.1 安装软件包

3.1.1 本地yum源配置参考如下

[root@linux8 ~]# mount /dev/cdrom /mnt/
mount: /mnt: WARNING: device write-protected, mounted read-only.
[root@linux8 ~]# 
[root@linux8 ~]# cat /etc/yum.repos.d/linux8.repo 
[BaseOS]
name=BaseOS
baseurl=file:///mnt/BaseOS
gpgcheck=0
enbaled=1
[AppStream]
name=AppStream
baseurl=file:///mnt/AppStream
gpgcheck=0
enabled=1
[root@linux8 ~]# 

3.1.2 安装软件包

因为有的包安装被忽略，所以最终进行多次安装。这里安装不全的话，图形化安装检测的时候也能提示出来。

yum install -y psmisc  binutils compat-libstdc++-33 gcc gcc-c++ glibc glibc-common  glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat openssh-clients compat-libcap1   xorg-x11-utils xorg-x11-xauth elfutils unixODBC unixODBC-devel libXp elfutils-libelf elfutils-libelf-devel smartmontools glibc-headers
yum install -y bc  binutils  compat-openssl10  elfutils-libelf  glibc  glibc-devel  ksh  libaio  libXrender  libX11  libXau  libXi  libXtst  libgcc  libnsl  libstdc++  libxcb  libibverbs  make  policycoreutils  policycoreutils-python-utils  smartmontools  sysstat
yum install -y gcc  gcc-c++ libaio-devel  elfutils-libelf-devel  libstdc++-devel pdksh

四、安装过程

4.1 安装db soft

安装检测过程中问题：

根据官方文档说明，这两个包可以忽略。
但是因为我本地有如下包，也选择了安装。
compat-libstdc+±33-3.2.3-72.el7.x86_64.rpm
pdksh-5.2.14-37.el5.x86_64.rpm

官方文档截图如下：

link过程中问题：

安装到86%的时候，ins_precomp.mk link报错。
根据官方文档说明，link报错全部忽略，点击continue后，后面提示的报错也全部continue,最终安装完成。

官方文档截图如下：

4.2 应用DBPSU 11.2.0.4.220118

安装opatch，应用PSU

[oracle@linux8 soft]$ unzip p6880880_112000_Linux-x86-64.zip -d $ORACLE_HOME

[oracle@linux8 soft]$ unzip p33477185_112040_Linux-x86-64.zip
[oracle@linux8 soft]$ cd 33477185/

opatch prereq CheckConflictAgainstOHWithDetail -ph ./
opatch apply

根据官方文档，出现任何link失败的问题，先忽略。
安装过程relink报错如下：

4.3 应用one-off patch 33991024

The one-off patch 33991024 will take care of the database linking errors and DBPSU 11.2.0.4.220118 patch warnings.

[oracle@linux8 soft]$ unzip p33991024_11204220118_Generic.zip
[oracle@linux8 soft]$ cd 33991024/

writing relink log to: /u01/app/oracle/product/11.2.0/db_1/install/relink.log
[oracle@linux8 soft]$

Relink过程中会出现的error,可以忽略

[oracle@linux8 ~]$ grep -in err /u01/app/oracle/product/11.2.0/db_1/install/relink.log
778:collect2: error: ld returned 1 exit status
780:make[1]: *** [/u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk:135: /u01/app/oracle/product/11.2.0/db_1/sysman/lib/emagent] Error 1

4.6 创建DB

五、总结

安装过程忽略link错误，然后安装必要的PSU及one off patch后手工执行relink，最终安装完成。
