做的好的装修公司网站搜索引擎优化的主要工作有

在openEuler-23.09上安装Oracle19c，创建非容器数据库实例(含静默安装)

操作系统版本
openEuler-23.09-x86_64-dvd.iso ，安装步骤此处省略。。。

最常用且直接的方法来查看openEuler的版本号是查看/etc/os-release文件

[root@openEuler ~]$ cat /etc/os-release
NAME="openEuler"
VERSION="23.09"
ID="openEuler"
VERSION_ID="23.09"
PRETTY_NAME="openEuler 23.09"
ANSI_COLOR="0;31"

Oracle19c
LINUX.X64_193000_db_home.zip

特殊说明
LINUX.X64_193000_db_home.zip 该文件你可以直接放到ORACLE_HOME目录下或者你解压的时候，将压缩包里的内容解压到$ORACLE_HOME目录下即可

1、操作系统配置

1.1、配置/etc/hosts

[root@openEuler tmp]# cat /etc/hosts
# Loopback entries; do not change.
# For historical reasons, localhost precedes localhost.localdomain:
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.80.239 openEuler

1.2、检查主机名和网络

[root@openEuler tmp]# hostname
openEuler
[root@openEuler tmp]# ping openEuler
PING openEuler (192.168.80.239) 56(84) bytes of data.
64 bytes from openEuler (192.168.80.239): icmp_seq=1 ttl=64 time=0.065 ms
64 bytes from openEuler (192.168.80.239): icmp_seq=2 ttl=64 time=0.036 ms
64 bytes from openEuler (192.168.80.239): icmp_seq=3 ttl=64 time=0.038 ms

1.3、关闭防火墙

-- 检查防火墙状态
[root@openEuler tmp]# systemctl status firewalld.service
