環境準備

安裝包:

本教程是在VMware下安裝的，注意設置內存的時候，不要設置動態內存。

安裝Oracle前準備

創建運行oracle數據庫的系統用戶和用戶組

[jonathan@localhost ~]$ su root　　#切換到rootPassword:[root@localhost]# groupadd oinstall　　#創建用戶組oinstall[root@localhost]# groupadd dba　　#創建用戶組dba[root@localhost]# useradd -g oinstall -g dba -m oracle　　#創建oracle用戶，并加入到oinstall和dba用戶組[root@localhost]# passwd oracle　　#設置用戶oracle的登陸密碼，不設置密碼，在CentOS的圖形登陸界面沒法登陸Changing password for user oracle.New password: 　　# 密碼BAD PASSWORD: The password is shorter than 8 charactersRetype new password: 　　# 確認密碼passwd: all authentication tokens updated successfully.[root@localhost]# id oracle # 查看新建的oracle用戶uid=1001(oracle) gid=1002(dba) groups=1002(dba)

創建oracle數據庫安裝目錄

[jonathan@localhost ~]$ su rootPassword:[root@localhost]# mkdir -p /data/oracle　　#oracle數據庫安裝目錄[root@localhost]# mkdir -p /data/oraInventory　　#oracle數據庫配置文件目錄[root@localhost]# mkdir -p /data/database　　#oracle數據庫軟件包解壓目錄[root@localhost]# cd /data[root@localhost data]# ls　　#創建完畢檢查一下（強迫癥）database oracle oraInventory[root@localhost data]# chown -R oracle:oinstall /data/oracle　　#設置目錄所有者為oinstall用戶組的oracle用戶[root@localhost data]# chown -R oracle:oinstall /data/oraInventory[root@localhost data]# chown -R oracle:oinstall /data/database[root@localhost data]#

修改OS系統標識

Oracle默認不支持CentOS系統安裝，Oracle Database 11g Release 2 的 OS要求參考：link

修改文件 /etc/RedHat-release

[root@localhost data]# cat /proc/versionLinux version 3.10.0-327.el7.x86_64 ([email protected]) (gcc version 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) ) #1 SMP Thu Nov 19 22:10:57 UTC 2015[root@localhost data]# cat /etc/redhat-release　　CentOS Linux release 7.1.1503 (Core)[root@localhost data]# vi /etc/redhat-release[root@localhost data]# cat /etc/redhat-releaseredhat-7[root@localhost data]#

安裝oracle數據庫所需要的軟件包

Oracle Database Package Requirements for Linux x86-64 如下：（參考：https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#BABCFJFG）

復制代碼 代碼如下:
yum install gcc* gcc-* gcc-c++-* glibc-devel-* glibc-headers-* compat-libstdc* libstdc* elfutils-libelf-devel* libaio-devel* sysstat* unixODBC-* pdksh-*

根據具體情況去安裝,上面只是提供了一個大概的內容，不是很全

關閉防火墻

CentOS 7.2默認使用的是firewall作為防火墻

[root@localhost /]# systemctl status firewalld.service　　#查看防火墻狀態，運行中● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2016-04-07 18:54:29 PDT; 2h 20min ago Main PID: 802 (firewalld) CGroup: /system.slice/firewalld.service  └─802 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopidApr 07 18:54:25 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...Apr 07 18:54:29 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.[root@localhost /]# systemctl stop firewalld.service　　#關閉防火墻[root@localhost /]# systemctl status firewalld.service　　#再次查看防火墻狀態，發現已關閉● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: inactive (dead) since Thu 2016-04-07 21:15:34 PDT; 9s ago Main PID: 802 (code=exited, status=0/SUCCESS)Apr 07 18:54:25 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...Apr 07 18:54:29 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.Apr 07 21:15:33 localhost systemd[1]: Stopping firewalld - dynamic firewall daemon...Apr 07 21:15:34 localhost systemd[1]: Stopped firewalld - dynamic firewall daemon.[root@localhost /]# systemctl disable firewalld.service　　#禁止使用防火墻（重啟也是禁止的）Removed symlink /etc/systemd/system/dbus-org.Fedoraproject.FirewallD1.service.Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.[root@localhost /]#
