CentOS7.9环境Oracle12c静默安装

一、系统配置 

查看系统架构

[root@oracle ~]# uname -m
x86_64

查看安装版本

[root@oracle ~]# more /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

更改本机名

[root@oracle ~]# vi /etc/hostname #按I修改修改保存好后ESC :wq
[root@oracle ~]# cat /etc/hostname
oracle

添加本机hosts文件

#输入ifconfig，确认主机地址
[root@oracle ~]# ifconfig   #ip addr 也可以看见主机的IP地址

#  esc 退出编辑模式 :wq 保存并退出

关闭selinux和防火墙(根据需要来做)

[root@oracle ~]# vi /etc/selinux/config 


# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled   #原值为SELINUX=enforcing
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

#检查防火墙状态
systemctl status firewalld
#关闭防火墙
systemctl stop firewalld
#禁用防火墙
systemctl disable firewalld
