安装包 网盘地址
[root@oracleMaster ~]# vim /etc/selinux/config
修改 SELINUX 为 disabled
# 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 #此处修改为disable
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@oracleMaster ~]# setenforce 0
setenforce: SELinux is disabled
不推荐
systemctl stop firewalld.service
推荐
查看端口是否开放:
firewall-cmd --query-port=1521/tcp
永久开放1521端口号:
firewall-cmd --permanent --zone=public --add-port=1521/tcp
重启防火墙:
systemctl restart firewalld.service
查看防火墙状态
systemctl status firewalld.service

检查一下配置是否已经写入文件
sysctl -p
vim /etc/security/limits.conf
在文件末尾增加配置
#oracle config date 2023-07-12
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

vim /etc/pam.d/login
文件末尾增加如下配置
session required /lib64/security/pam_limits.so
session required pam_limits.so
vim /etc/profile
文件末尾增加如下配置
##oracle config date 2023-07-12
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536

mkdir -p /data/oracle/product/11.2.0/db_01
mkdir /data/oracle/oradata
mkdir /data/oracle/inventory
mkdir /data/oracle/fast_recovery_area
chown -R oracle:oinstall /data/oracle
chmod -R 775 /data/oracle
vim /etc/hosts
在文件末尾增加如下配置,对应两台机器的ip和用户名
192.168.46.61 oracleMaster
创建安装包存放目录
[root@oracleMaster ~]# mkdir -p /opt/oracle
[root@oracleMaster oracle]# pwd
/opt/oracle
将 2个安装包放到此目录下
[root@oracleMaster oracle]# ls
linux.x64_11gR2_database_1of2.zip linux.x64_11gR2_database_2of2.zip
解压安装包,会得到一个 database 文件夹
[root@oracleMaster oracle]# ls
database linux.x64_11gR2_database_1of2.zip linux.x64_11gR2_database_2of2.zip
这个目录会在安装时使用
/opt/oracle/database
切换到 oracle 用户
[root@oracleMaster ~]# su -l oracle
上一次登录:三 7月 12 10:28:39 CST 2023pts/0 上
[oracle@oracleMaster ~]$ vim .bash_profile
在文件末尾增加如下配置
ORACLE_BASE=/data/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_01
ORACLE_SID=orcl
PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
使环境变量生效
source .bash_profile
登录 oracle 用户,在 oracle 用户下面操作
[root@oracleMaster ~]# su -l oracle
Last login: Thu Jul 13 22:30:30 EDT 2023 on pts/0
[oracle@oracleMaster ~]$
[oracle@oracleMaster ~]$ cp -R /opt/oracle/database/response .
安装文件在一、安装前准备 第11步骤那个目录下面
[oracle@oracleMaster ~]$ cd response
[oracle@oracleMaster response]$ vim db_install.rsp
修改如下配置
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=CentOS
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/data/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOME=/data/oracle/product/11.2.0/db_01
ORACLE_BASE=/data/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba
DECLINE_SECURITY_UPDATES=true
cd /opt/oracle/database
./runInstaller -silent -responseFile /home/oracle/response/db_install.rsp -ignorePrereq
安装时会遇到一些问题,运气好的话全程不会报错,主要看机器的环境(我是新搭虚拟机,干净环境)
当出现:
The following configuration scripts need to be executed as the "root" user.
#!/bin/sh
#Root scripts to run
/data/oracle/inventory/orainstRoot.sh
/data/oracle/product/11.2.0/db_01/root.sh
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts
4. Return to this window and hit "Enter" key to continue
Successfully Setup Software.
Successfully Setup Software表示安装成功
,中间提示warning不需要理会,当提示成功以后可以退出当前窗口了,然后根据提示执行脚本切换到root用户继续执行一下操作
[oracle@oracleMaster ~]$ exit
logout
[root@oracleMaster ~]#
sh /data/oracle/inventory/orainstRoot.sh
sh /data/oracle/product/11.2.0/db_01/root.sh
启动监听:lsnrctl start
停止监听:lsnrctl stop
重启监听:lsnrctl reload
查看监听:lsnrctl status
切换到oracle 用户
su -l oracle
$ORACLE_HOME/bin/netca /silent /responseFile /home/oracle/response/netca.rsp
查看是否监听成功
lsnrctl status
vim /home/oracle/response/dbca.rsp
填写下面的参数,SYSTEMPASSWORD 和 SYSTEMPASSWORD 必须设置不然不会安装,在ssh软件中安装会清屏,在 vmware esxi 中安装才会提示输入这两个用户的密码,坑
