1.软件准备

　　oracle12c.zip 安装包

　　VMware 虚拟机

　　redhat7.0 系统

　　Xmanagement

2. 在VMware下安装redhat7.0系统

　　注：硬盘80GB

3.配置linux7.0

　　3.1 IP 网关配置

[root@localhost ~]# nmcli conn modify eno16777736 ipv4.addresses ‘192.168.144.128/24 192.168.144.1‘
[root@localhost ~]# nmcli conn modify eno16777736 ipv4.method manual
[root@localhost ~]# nmcli conn modify eno16777736 connection.autoconnect yes

　　3.2 配置ssh服务端，停止在链接的ssh的时候启用dns解析

 　　vim /etc/ssh/sshd_config 
　　#UseDNS yes
    UseDNS no

　　3.3 禁用防火墙

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
   Active: inactive (dead)

　　3.4 禁用selinux

[root@localhost ~]# getenforce
Permissive
[root@localhost ~]# 
[root@localhost ~]# setenforce 0
[root@localhost ~]# 
[root@localhost ~]# vim /etc/selinux/
SELINUX=permissive

　　3.5 完成后重启

[root@localhost ~]# reboot

4. 　安装前配置

　　4.1 安装软件包

[root@localhost ~]# vim /etc/yum.repos.d/base.repo
    [base]
    name=base
    baseurl=file:///mnt
    enable=1
    gpgcheck=0

[root@localhost ~]# yum clean all

[root@localhost ~]# mount /dev/sr0 /mnt
mount: /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0 is already mounted or /mnt busy
       /dev/sr0 is already mounted on /mnt
[root@localhost ~]# 
[root@localhost ~]# yum install -y compat-libcap1 glibc-devel ksh libaio-devel libstdc++-devel gcc gcc-c++ uni

　　4.2系统组和用户

[root@localhost ~]# groupadd oinstall
[root@localhost ~]# groupadd dba
[root@localhost ~]# useradd -g oinstall -G dba oracle
[root@localhost ~]# echo oracle | passwd --stdin oracle
Changing password for user oracle.
passwd: all authentication tokens updated successfully.
[root@localhost ~]# id oracle
uid=1001(oracle) gid=1001(oinstall) groups=1001(oinstall),1002(dba)

　　4.3检查内核参数

1、共享内存
[root@localhost ~]# vim /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 429496729
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576


	生效该内核参数
[root@localhost ~]# sysctl -p

	2、资源限制
[root@localhost ~]# vim /etc/security/limits.conf
oracle              soft    nproc    2047
oracle              hard    nproc    16384
oracle              soft    nofile   1024
oracle              hard    nofile   65536
oracle              soft    stack    10240
oracle              hard    stack    10240

　　4.4 硬盘扩容，开机启动

[root@localhost ~]# fdisk /dev/sda

[root@localhost ~]# partprobe 

[root@localhost ~]# mkfs.xfs /dev/sda5

[root@localhost ~]# mkdir /u01
[root@localhost ~]# 
[root@localhost ~]# mount /dev/sda5 /u01

[root@localhost ~]# blkid
/dev/sda1: UUID="9bed2ed9-71b1-498f-be9c-445d3e20ed62" TYPE="xfs" 
/dev/sda2: UUID="cf5a1986-223c-46e3-a276-54718b9e21da" TYPE="swap" 
/dev/sda3: UUID="4f7c87bc-f4f6-4c9f-8bab-e82a423f7382" TYPE="xfs" 
/dev/sda5: UUID="013ca86b-4062-4ce7-aebb-177823462cb7" TYPE="xfs" 
/dev/sr0: UUID="2014-05-07-03-58-46-00" LABEL="RHEL-7.0 Server.x86_64" TYPE="iso9660" PTTYPE="dos" 
[root@localhost ~]# 
[root@localhost ~]# vim /etc/fstab

[root@localhost ~]# mount -a
[root@localhost ~]# 
[root@localhost ~]# mount

　　4.5 检查需要的目录，权限

[root@localhost ~]# cd /u01
[root@localhost u01]# mkdir app

[root@localhost ~]# chmod 775 /u01/ -R
[root@localhost ~]# chown oracle:oinstall /u01/ -R
[root@localhost ~]# 
[root@localhost ~]# ll /u01/ -d
drwxrwxr-x. 3 oracle oinstall 16 Aug  7 22:11 /u01/
[root@localhost ~]# ll /u01/app -d
drwxrwxr-x. 2 oracle oinstall 6 Aug  7 22:11 /u01/app

　注：权限修改不对，安装时会出现错误

　　4.6 复制安装文件到系统

[root@localhost ~]# cd /home/oracle/
[root@localhost oracle]# 
[root@localhost oracle]# ll
total 3372752
-rw-r--r--. 1 root root 3453696911 Aug  7 22:13 ORACLE12C.zip
[root@localhost oracle]# unzip ORACLE12C.zip 

[root@localhost oracle]# chmod 777 database/ -R
[root@localhost oracle]# chown oracle:oinstall database/ -R

　　4.7执行xhost +

[root@localhost oracle]# xhost +
access control disabled, clients can connect from any host
[root@localhost oracle]#

　4.8 重启

注：没有重启的话，出现错误

5. 安装oracle12C

5.1 oracle用户登录执行

[oracle@localhost ~]$ cd database/

[oracle@localhost database]$ ./runInstaller 
Starting Oracle Universal Installer...
Checking Temp space: must be greater than 500 MB.   Actual 9085 MB    Passed
Checking swap space: must be greater than 150 MB.   Actual 1999 MB    Passed
Checking monitor: must be configured to display at least 256 colors.    Actual 16777216    Passed
le@localhost database]$ You can find the log of this install session at:
 /u01/app/oraInventory/logs/installActions2017-08-07_10-18-09PM.log
[oracle@localhost database]$

5.2 安装步骤选项

5.3 安装停下的话，出现以下界面用root用户登录，执行脚本

技术分享

[root@localhost ~]# cd /home/oracle/
[root@localhost oracle]# cd database/

[root@localhost database]# /u01/app/oraInventory/orainstRoot.sh

[root@localhost database]# /u01/app/oracle/product/12.2.0/dbhome_1/root.sh

[root@localhost database]#

　注：执行第二个脚本，还要下一步，下一步，不然，无法成功安装数据库命令

6.进入SQL

oracle登录，进入

注： ORACLE_SID = [oracle] ? oracle01  注：oracle01为 数据库名字

[oracle@localhost database]$ . oraenv

ORACLE_SID = [oracle] ? oracle01
The Oracle base has been set to /u01/app/oracle

[oracle@localhost database]$ sqlplus / as sysdba

SQL> select instance_name,status from v$instance;
