一、环境准备

1.1 软件下载

下载地址：https://www.oracle.com/database/technologies/oracle19c-linux-downloads.html

其中client的是需要图形界面安装的，client_home是静默安装的，可自行选择，本文采用图形界面安装

1.2 基础环境配置

1. 修改主机名

# hostnamectl set-hostname node1

1. 关闭防火墙与SELinux

# systemctl stop firewalld
# systemctl disable firewalld
##如果打开防火墙的话，需放开Oracle1521端口
##firewall-cmd --zone=public --add-port=1521/tcp --permanent
##firewall-cmd --reload
# setenforce 0
# sed -ri '/^[^#]*SELINUX=/s#=.+$#=disabled#' /etc/selinux/config
# cat /etc/sysconfig/selinux
# getenforce

1. 配置本地yum源，如果有互联网这一步可以省略
2. 安装依赖包

dnf -y install gcc automake autoconf libtool make

1. 创建Oracle相关的用户和组

# /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 oracle
# echo "Gistack123" |passwd --stdin oracle
# /usr/sbin/usermod -g oinstall -G dba,oper oracle
# id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper)

1. 创建文件夹并赋权

# mkdir -p /u01/app/oracle/product/19.0.0/client_1
# mkdir -p /u01/soft
# chown -R oracle:oinstall /u01/
# chmod -R 775 /u01

1. 配置环境变量

# su - oracle
$ vim ~/.bash_profile
umask 022

export HOST=`hostname | cut -f1 -d"."`

export LANG=en_US

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.3/client_1
export ORACLE_SID=oratestdb
export ORACLE_TERM=xterm;
export PATH=.:$PATH:$HOME/.local/bin:$HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/bin
export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"
export NLS_LANG=AMERICAN_CHINA.ZHS16GBK
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

$ source ~/.bash_profile

1. 解压安装包

# unzip /software/LINUX.X64_193000_client.zip -d /u01/soft/
# chown -R oracle:oinstall /u01/

1. 配置DISPLAY环境变量

$ export DISPLAY=192.168.88.112:0.0

二、安装client

1. 运行安装程序

$ cd /u01/soft/
$ ./runInstaller

用的管理员模式安装，安装过程省略。
2. 配置客户端登录

$ vim /u01/app/oracle/product/19.3/client_1/network/admin/tnsnames.ora
ORATESTDB =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.88.75)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = oratestdb)
      (SERVER = DEDICATED)
    )
  )
  ## 其中ORATESTDB可以随便取，后面sqlplus的连接名用这个
  
  ## 测试登录
  $ sqlplus system/Gistack123@ORATESTDB

三、报错整理

1. 执行./runInstaller报错没有swap，创建swap

# dd if=/dev/zero of=/swapfile bs=1024MB count=4
# mkswap /swapfile
# chmod 0600 /swapfile
# swapon /swapfile
# swapon -s

1. 执行./runInstaller报错：libXext.so.6找不到

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2023-03-24_05-37-07PM. Please wait ...[oracle@vm088078 client]$ Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/OraInstall2023-03-24_05-37-07PM/jdk/jre/lib/amd64/libawt_xawt.so: libXext.s
o.6: cannot open shared object file: No such file or directory

##解决办法
# dnf -y install libXext.so.6

1. 执行./runInstaller报错无法执行xdpyinfo

>>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set.    Failed <<<<

## 解决办法
# dnf -y install xdpyinfo

1. 图形化安装报错：INS-08101

[INS-08101] Unexpected error while executing the action at state: 'clientSupportedOSCheck'

## 解决办法
$ export CV_ASSUME_DISTID=RHEL7.6
