-----------------------------

yum -y install compat-libstdc++-33

yum -y install elfutils-libelf-devel

yum -y install gcc

yum -y install gcc-c++

yum -y install glibc-devel

yum -y install glibc-headers

yum -y install ksh

yum -y install libaio-devel

yum -y install libstdc++-devel

yum -y install unixODBC

yum -y install unixODBC-devel

yum -y install compat-libcap1

安装cvu包，进入到grid解压后的目录

cd /soft/grid/rpm

rpm -ivh cvuqdisk-1.0.9-1*

1、修改hosts

如果有多个scan ip ，那么scan ip不能添加到hosts中。

如果只有一个scan ip，将scan ip添加到hosts中

vi /etc/hosts

192.168.56.101 ogg1

192.168.56.102 ogg2

10.10.10.1 oggpriv1

10.10.10.2 oggpriv2

192.168.56.201 oggvip1

192.168.56.202 oggvip2

192.168.56.110 scanip

如果在dns中配置了ip，那么就得在所有节点上更改主机的搜索顺序

vi /etc/nsswitch.conf

Old:

hosts: files nis dns

New:

hosts: dns files nis

重启服务

#/sbin/service nscd restart

2、修改limit限制

vi /etc/security/limits.conf

添加如下内容

grid soft nproc 2047

grid hard nproc 16384

grid soft nofile 1024

grid hard nofile 65536

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

3、修改/etc/profile文件

添加如下内容

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

fi

4、修改/etc/csh.login

添加如下内容

if ( $USER = "oracle" || $USER = "grid" ) then

limit maxproc 16384

limit descriptors 65536

endif

5、配置核心参数

vi /etc/sysctl.conf

添加如下内容

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 6553600

fs.aio-max-nr = 1048576

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

配置后执行

sysctl -p

6、配置/etc/pam.d/login文件

vi /etc/pam.d/login

添加如下内容

session required pam_limits.so

7、添加用户和组

/usr/sbin/groupadd -g 501 oinstall

/usr/sbin/groupadd -g 502 dba

/usr/sbin/groupadd -g 504 asmadmin

/usr/sbin/groupadd -g 506 asmdba

/usr/sbin/groupadd -g 507 asmoper

/usr/sbin/useradd -u 501 -g oinstall -G asmadmin,asmdba,asmoper,dba grid

/usr/sbin/useradd -u 502 -g oinstall -G dba,asmdba oracle

passwd oracle

passwd grid

8、创建目录

创建oracle目录

mkdir -p /u01/app/oraInventory

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

chmod -R 775 /u01/app/oraInventory

创建grid目录

mkdir -p /u01/app/11.2.0/grid/product/db_1

chown -R grid:oinstall /u01/app/11.2.0/grid/product/db_1

chmod -R 775 /u01/app/11.2.0/grid/product/db_1

mkdir -p /u01/app/grid

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

chmod -R 775 /u01/app/grid

创建ORACLE_BASE目录和rdbms目录

mkdir -p /u01/app/oracle

mkdir /u01/app/oracle/cfgtoollogs

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

chmod -R 775 /u01/app/oracle

mkdir -p /u01/app/oracle/product/11.2.0/db_1

chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1

chmod -R 775 /u01/app/oracle/product/11.2.0/db_1

9、配置raw

修改/etc/udev/rules.d/60-raw.rules 文件

添加如下内容：

ACTION=="add", KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add", KERNEL=="sdd1",RUN+="/bin/raw /dev/raw/raw3 %N"

ACTION=="add", KERNEL=="sde1",RUN+="/bin/raw /dev/raw/raw4 %N"

ACTION=="add", KERNEL=="sdf1",RUN+="/bin/raw /dev/raw/raw5 %N"

ACTION=="add", KERNEL=="sdg1",RUN+="/bin/raw /dev/raw/raw6 %N"

ACTION=="add", KERNEL=="sdh1",RUN+="/bin/raw /dev/raw/raw7 %N"

KERNEL=="raw[1-7]",OWNER="grid",GROUP="asmadmin" MODE="660"

添加完成后执行如下命令

start_udev

raw -qa

--partprobe

10、关闭ntp服务

使用oracle11G rac的时间同步

service ntpd stop

chkconfig ntpd off

mv /etc/ntp.conf /etc/ntp.conf.orig

rm /var/run/ntpd.pid

11、配置环境变量

su - oracle

vi .bash_profile

添加如下内容

export TMP=/tmp;

export TMPDIR=$TMP;

export ORACLE_BASE=/u01/app/oracle;

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1;

export ORACLE_SID=racdb1; （在第二个节点为racdb2）

export ORACLE_TERM=xterm;

export PATH=/usr/sbin:$PATH;

export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH;

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

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

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK;

配置结束后执行：source .bash_profile

su - grid

vi .bash_profile

添加如下内容

export TMP=/tmp;

export TMPDIR=$TMP;

export ORACLE_SID=+ASM1; （在第二个节点为+ASM2）

export ORACLE_BASE=/u01/app/grid;

export ORACLE_HOME=/u01/app/11.2.0/grid/product/db_1;

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

export THREADS_FLAG=native;

export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH;

export THREADS_FLAG=native;

export PATH=$ORACLE_HOME/bin:$PATH;

配置结束后执行：source .bash_profile

11、配置互信（可以在安装grid和oracle软件的时候通过图形界面执行，建议在图形界面配置）

cd /u01/soft

unzip p10404530_112030_Linux-x86-64_3of7.zip

su - grid

cd grid/sshsetup

./sshUserSetup.sh -user grid -hosts "ogg1 ogg2" -advanced -noPromptPassphrase

cd /u01/soft

unzip p10404530_112030_Linux-x86-64_1of7.zip

unzip p10404530_112030_Linux-x86-64_2of7.zip

su - oracle

cd /u01/soft/database/sshsetup/

./sshUserSetup.sh -user oracle -hosts "ogg1 ogg2" -advanced -noPromptPassphrase
