1. 安裝前准備
[1] 安裝軟件包
yum -y install binutils compat-libcap1 compat-libstdc++.i686 compat-libstdc++.x86_64 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc.i686 glibc.x86_64 glibc-devel.i686 glibc-devel.x86_64 ksh libgcc.i686 libgcc.x86_64 libstdc++.i686 libstdc++.x86_64 libstdc++-devel.i686 libstdc++-devel.x86_64 libaio.i686 libaio.x86_64 libaio-devel.i686 libaio-devel.x86_64 libXext libXtst libX11 libXau libxcb libXi make sysstat unixODBC-devel.i686 unixODBC-devel.x86_64 unixODBC.i686 unixODBC.x86_64 compat-libstdc++-33.i686 compat-libstdc++-33.x86_64
安裝軟件包 pdksh-5.2.14-36.el5.i386.rpm (這個包yum源里沒有,所以要手動安裝,不裝安裝oracle時會有警告出現,但不影響最后的使用)
請下載這個包上傳到CentOS后使用如下命令安裝。(單擊文件名稱下載)
[root@localhost public_root]# rpm -ivh pdksh-5.2.14-36.el5.i386.rpm
[2] 更改kernel參數
[root@localhost var]# vi /etc/sysctl.conf
# Disable netfilter on bridges.
#net.bridge.bridge-nf-call-ip6tables = 0
#net.bridge.bridge-nf-call-iptables = 0
#net.bridge.bridge-nf-call-arptables = 0
# Controls the default maxmimum size of a mesage queue
kernel.msgmnb = 65536
# Controls the maximum size of a message, in bytes
kernel.msgmax = 65536
# Controls the maximum shared segment size, in bytes
kernel.shmmax = 4294967295
# Controls the maximum number of shared memory segments, in pages
kernel.shmall = 268435456
# 在文件末尾添加
net.ipv4.ip_local_port_range = 9000 65500
fs.file-max = 6815744
kernel.shmall = 10523004
kernel.shmmax = 6465333657
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_max=1048576
fs.aio-max-nr = 1048576
執行以下命令使更改生效
[root@localhost var]# sysctl -p
[3] 創建安裝oracle所需用戶與用戶組
[root@localhost var]# groupadd -g 200 oinstall
[root@localhost var]# groupadd -g 201 dba
[root@localhost var]# useradd -u 440 -g oinstall -G dba -d /usr/oracle oracle
[root@localhost var]# passwd oracle
[root@localhost var]# vi /etc/pam.d/login
#%PAM-1.0
auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth include system-auth
account required pam_nologin.so
account include system-auth
password include system-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session required pam_loginuid.so
session optional pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open
session required pam_namespace.so
session required pam_limits.so
session optional pam_keyinit.so force revoke
session include system-auth
-session optional pam_ck_connector.so
[root@localhost var]# vi /etc/security/limits.conf
# 在文件末尾添加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
[root@localhost var]# vi /etc/profile
# 在文件末尾添加
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
[4] 切換到oracle用戶,並進行配置
[root@localhost ~]# su - oracle
[oracle@localhost ~]$ chmod 755 /usr/oracle
[oracle@localhost ~]$ mkdir /usr/oracle/app
[oracle@localhost ~]$ chmod 755 /usr/oracle/app/
[oracle@localhost ~]$ mkdir /usr/oracle/oradata
[oracle@localhost ~]$ chmod 755 /usr/oracle/oradata/
[oracle@localhost ~]$ vi ./.bash_profile
# 在文件末尾添加
umask 022
export ORACLE_BASE=/usr/oracle/app
2. 安裝oracle database
[1] 下載oracle安裝文件(for linux x86),並上傳到CentOS上
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
[2] 解壓安裝文件
[root@localhost public_root]# unzip linux_11gR2_database_1of2.zip
[root@localhost public_root]# unzip linux_11gR2_database_2of2.zip
[3] 以oracle用戶登陸,startx命令啟動圖形界面,打開一個終端窗口,進行到剛剛解壓database的文件夾,運行以下命令
[oracle@localhost database]$ ./runInstaller
[4] oracle安裝界面啟動如下圖所示,輸入郵件地址及密碼(oracle用戶),以從oralce接收安全更新等信息
[5] 僅安裝數據庫軟體
[6] 本實例中選擇安裝單實例數據庫
[7] 選擇語言
[8] 選擇要安裝的版本,這里選擇 “Enterprise Edition”
[9] 指定Oracle Base 與 Software Location, 我們在oracle用戶的profile文件里已設置此環境變量,此處保持默認
[10] 指定Inventory Directory, 本例保持默認
[11] 指定oralce特權用戶組,本例保持默認
[12] 接下來,oralce安裝程序會對安裝環境進行檢查,本例未檢查到任何問題,顯示安裝信息如下。直接Finish, 開始安裝。
[13] 靜待oracle安裝
[14] 當出現以下窗口時,另開一個終端,以root用戶登陸,並執行下面的命令。執行完畢后,點擊OK
[root@localhost ~]# /usr/oracle/oraInventory/orainstRoot.sh
Changing permissions of /usr/oracle/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.
Changing groupname of /usr/oracle/oraInventory to oinstall.
The execution of the script is complete.
[root@localhost ~]# /usr/oracle/app/product/11.2.0/dbhome_1/root.sh
Running Oracle 11g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /usr/oracle/app/product/11.2.0/dbhome_1
[15] 至此oracle 11g R2數據庫安裝完畢。
[16] 環境變量配置
[oracle@localhost ~]$ vi ~/.bash_profile
# 文件末尾增加
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export PATH=$PATH:$ORACLE_HOME/bin
