一、安装前配置

1.1、配置本地主机名解析  /etc/hosts

1.2、 禁用 selinux

# 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
# 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

重启验证 [root@rhel64 ~]# reboot

[root@rhel64 ~]# getenforce

1.3、配置 yum 软件仓库

[root@ora19c ~]# mkdir /mnt/dvd
[root@ora19c ~]# mount /dev/sr0 /mnt/dvd
[root@ora19c ~]# df -Th

 在默认配置文件中追加写入信息

[root@ora19c ~]# vi /etc/yum.repos.d/rhel-source.repo

[rhel6.4]
name=rhel64
baseurl=file:///mnt/dvd/Server
gpgcheck=0

[root@rhel64 ~]# yum clean all
[root@rhel64 ~]# yum list
[root@rhel64 ~]# yum install lrzsz

二、软件安装环境准备

2.1  yum安装软件包

[root@ora19c ~]# yum install gcc* binutils* compat* glibc* ksh* libgcc* libstdc* libaio* make* sysstat* unixODBC* -y

2.2  创建用户和组

[root@ora19c ~]# groupadd oinstall
[root@ora19c ~]# groupadd dba
[root@ora19c ~]# groupadd oper
[root@ora19c ~]# useradd -g oinstall -G dba,oper oracle
[root@ora19c ~]# passwd oracle

[oracle@ora19c ~]$ id
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba),1003(oper)

[root@ora19c ~]# mkdir -p /u01/app/oracle
[root@ora19c ~]# chown -R oracle:oinstall /u01
[root@ora19c ~]# chmod -R 775 /u01/app/oracle

unset TNS_ADMIN
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.3.0/dbhome_1
export ORACLE_SID=PROD
export PATH=$ORACLE_HOME/bin:$PATH

[oracle@ora19c ~]$ source .bash_profile
[oracle@ora19c ~]$ echo $ORACLE_BASE
/u01/app/oracle
[oracle@ora19c ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/19.3.0/dbhome_1
[oracle@ora19c ~]$ echo $ORACLE_SID
PROD

[root@ora19c u01]# mkdir software

[oracle@ora19c ~]$ cd /u01/software/
[oracle@ora19c software]$ ll
total 2987996
-rw-r--r-- 1 root root 3059705302 May 30 05:58 LINUX.X64_193000_db_home.zip

[oracle@ora19c ~]$ unzip /u01/software/LINUX.X64_193000_db_home.zip -d $ORACLE_HOME/

[oracle@dba ~]$ export DISPLAY=192.168.100.1:0.0
[oracle@ora19c ~]$ cd $ORACLE_HOME
