本文文檔結構：

這一步的DG機器配置就相當于安裝單實例的DB+ASM 一樣，這里我把之前的文檔內容直接拷貝過來了，也不做過多的解釋了

1. 安裝之前的配置工作

1. 檢查硬件

在正式安裝開始前，請先檢查你的軟硬件條件是否滿足安裝需要。

硬件上可以使用命令查看內存情況和 CPU 特性：

#more /proc/meminfo

#more /proc/cpuinfo

其中內存的要求是不低于 1G

下面的不是必須的，可選使用

#df –k /dev/shm 檢查共享內存

#df –k /tmp 檢查臨時磁盤空間

#more /proc/version 檢查操作系統版本

#uname –r 檢查內核版本

內存

# grep MemTotal /proc/meminfo

交換空間

# grep SwapTotal /proc/meminfo

磁盤空間

# df -ah

# free

#free -m

1. 安裝軟件包檢查

可以統一檢查：

rpm -q binutils \

compat-libstdc++-33 \

elfutils-libelf \

gcc \

gcc-c++ \

glibc \

glibc-common \

glibc-devel \

glibc-headers \

ksh \

libaio \

libaio-devel \

libgomp \

libgcc \

libstdc++ \

libstdc++-devel \

make \

sysstat \

unixODBC \

unixODBC-devel \

numactl-devel

我們可以看到沒有安裝過的包會已is not installed 出現：

[root@rhel6_lhr ~]# rpm -q binutils \

[root@rhel6_lhr ~]#

如果部分包不存在

可以批量更新安裝，但如果依賴關系缺失，可能需要多執行兩遍

或者手工調整

1. 修改主機名

永久生效：

[root@zijuan /]# vim /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=yes

HOSTNAME=dg

注意：修改主機名后，需要重啟系統后生效，或者切換個用戶然后切換回來就OK

查看/etc/hosts文件中必須包含a fully qualified name for the server

 [root@localhost lhr]# cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.59.140 dg

[root@localhost lhr]# hostname dg

[root@localhost lhr]# hostname

dg

1. 磁盤準備

這里為了節省空間，我們采用dd命令來faking 5塊裸設備磁盤

1塊硬盤安裝操作系統

234塊用于實現ASM 存儲數據

5塊硬盤用于存儲FRA

------------------------ 直接貼腳本，root用戶下執行

mkdir /asmdisk

losetup –d /dev/loop1

1. 配置目錄、用戶等

1. 配置用戶及用戶組

利用 /usr/sbin/groupadd 命令

------這里Oracle用戶可能已經安裝過的，沒有影響：

代碼：

groupadd oinstall

groupadd dba

groupadd oper

groupadd asmadmin

groupadd asmoper

groupadd asmdba

--添加用戶到組

useradd -g oinstall -G dba,asmdba,oper,asmadmin oracle

useradd -g oinstall -G asmadmin,asmdba,asmoper,dba grid

--修改密碼

passwd oracle

passwd grid

echo oracle | passwd --stdin lhr

echo grid | passwd --stdin lhr

---查看屬主

[root@rhel_linux_asm ~]# id oracle

uid=501(oracle) gid=502(dba) groups=502(dba),501(oinstall),504(asmadmin),506(asmdba)

[root@rhel_linux_asm ~]# id grid

uid=502(grid) gid=501(oinstall) groups=501(oinstall),502(dba),504(asmadmin),505(asmoper),506(asmdba)

[root@rhel_linux_asm ~]#

1. 創建目錄并且配置 grid 和 oracle 用戶的配置文件

代碼：

--root用戶下：

mkdir -p /u01/app/oracle

mkdir -p /u01/app/grid

mkdir -p /u01/app/11.2.0/grid

chown -R grid:oinstall /u01/app/grid

chown -R grid:oinstall /u01/app/11.2.0/grid

chown -R oracle:oinstall /u01/app/oracle

chmod -R 775 /u01

mkdir -p /u01/app/oraInventory

chown -R grid:oinstall /u01/app/oraInventory

chmod -R 775 /u01/app/oraInventory

--------Oracle User----切換到Oracle用戶下------

[root@rhel_linux_asm ~]# su - oracle

[grid@rhel_linux_asm ~]$ vi ~/.bash_profile

export ORACLE_SID=phydb

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

alias alert_listener='tail -200f $ORACLE_BASE/diag/tnslsnr/rhel6/listener/trace/listener.log'

--------Grid User-----切換到grid用戶下-----

cd /home/grid

vim .bash_profile

export ORACLE_SID=+ASM

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/11.2.0/grid

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"

export PATH=$ORACLE_HOME/bin:$PATH

alias sqlplus='rlwrap sqlplus'

alias asmcmd='rlwrap asmcmd'

alias alert_log='tail -200f $ORACLE_BASE/diag/asm/+asm/$ORACLE_SID/trace/alert_$ORACLE_SID.log'

修改完成后執行source .bash_profile 讓設置生效

1. 系統內核參數修改

   1. 編輯 /etc/security/limits.conf 文件，在文件尾部添加如下內容：

[root@localhost ~]# tail -8 /etc/security/limits.conf

# add by lhr for oracle and grid on 2014-05-02

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

grid soft nproc 2047

grid hard nproc 16384

grid soft nofile 1024

grid hard nofile 65536

1. 編輯 /etc/pam.d/login 文件，在文件尾部添加如下內容：

[root@localhost ~]# tail -1 /etc/pam.d/login

session required pam_limis.so

[root@localhost ~]#

1. 編輯 /etc/profile 文件，設置 shell 限制，在文件尾部添加如下內容：

[root@localhost ~]# tail -9 /etc/profile

if [ /$USER = "oracle" ] || [ /$USER = "grid" ]; then

if [ /$SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

umask 022
