2.停不必要的服务[RHEL5U1]
chkconfig acpid off
chkconfig anacron off
chkconfig apmd off
chkconfig auditd off
chkconfig autofs off
chkconfig avahi-daemon off
chkconfig bluetooth off
chkconfig cpuspeed off
chkconfig cups off
chkconfig firstboot off
chkconfig gpm off
chkconfig haldaemon off
chkconfig hidd off
chkconfig ip6tables off
chkconfig iptables off
chkconfig irqbalance off
chkconfig isdn off
chkconfig mcstrans off
chkconfig mdmonitor off
chkconfig microcode_ctl off
chkconfig netfs off
chkconfig pcscd off
chkconfig readahead_early off
chkconfig restorecond off
chkconfig rhnsd off
chkconfig rpcgssd off
chkconfig rpcidmapd off
chkconfig sendmail off
chkconfig setroubleshoot off
chkconfig smartd off
chkconfig xfs off
chkconfig yum-updatesd off
3.修改系统配置参数/etc/sysctl.conf
echo "kernel.shmall = 2097152">>/etc/sysctl.conf
echo "kernel.shmmax = 4294967295">>/etc/sysctl.conf
echo "kernel.shmmni = 4096">>/etc/sysctl.conf
echo "kernel.sem = 250 32000 100 128">>/etc/sysctl.conf
echo "net.ipv4.ip_local_port_range = 9000 65500">>/etc/sysctl.conf
echo "net.core.rmem_default = 262144">>/etc/sysctl.conf
echo "net.core.rmem_max = 2097152">>/etc/sysctl.conf
echo "net.core.wmem_default = 262144">>/etc/sysctl.conf
echo "net.core.wmem_max = 1048576">>/etc/sysctl.conf
echo "fs.file-max = 262144">>/etc/sysctl.conf
让参数生效
sysctl -p
注：
shmall 是全部允许使用的共享内存大小，shmmax 是单个段允许使用的大小。这两个可以设置为内存的 90%。
例如 16G 内存，16*1024*1024*1024*90% = 15461882265，shmall 的大小为 15461882265/4k(getconf PAGESIZE可得到) = 3774873。
5.创建Oracle用户和组
groupadd -g 600 oinstall
groupadd -g 601 dba
groupadd -g 602 oper
useradd -u 600 -g oinstall -G dba,oper oracle -d /home/oracle
passwd oracle
6.创建ORACLE安装目录变更属主
mkdir -p /oracle/product/10.2.0/crs
mkdir -p /oracle/product/10.2.0/db
chown -R oracle:oinstall /oracle
7.修改ORACLE用户默认限制
echo "oracle soft nproc 2047">>/etc/security/limits.conf
echo "oracle hard nproc 16384">>/etc/security/limits.conf
echo "oracle soft nofile 4096">>/etc/security/limits.conf
echo "oracle hard nofile 65536">>/etc/security/limits.conf
echo "session required /lib/security/pam_limits.so">>/etc/pam.d/login
echo "session required pam_limits.so">>/etc/pam.d/login
echo "if [ $USER = "oracle" ]; then">>/etc/profile
echo " if [ $SHELL = "/bin/ksh" ]; then">>/etc/profile
echo " ulimit -p 16384">>/etc/profile
echo " ulimit -n 65536">>/etc/profile
echo " else">>/etc/profile
echo " ulimit -u 16384 -n 65536">>/etc/profile
echo " fi">>/etc/profile
echo "fi">>/etc/profile
8.配置ORACLE环境变量
1）ORACLE用户.bash_profile
su - oracle
echo "export ORACLE_BASE=/oracle">>~/.bash_profile
echo "export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db">>~/.bash_profile
echo "export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs">>~/.bash_profile
echo "export ORACLE_SID=racdb1 # The Second Node is Named racdb2">>~/.bash_profile
echo "export PATH=$PATH:$ORA_CRS_HOME/bin:$ORACLE_HOME/bin:$ORACLE_HOME/dcm/bin:$ORACLE_HOME/webcache/bin:$ORACLE_HOME/opmn/bin">>~/.bash_profile
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:/usr/lib:/usr/local/lib">>~/.bash_profile
echo "export TMPDIR=/tmp">>~/.bash_profile
echo "export TMP=/tmp">>~/.bash_profile
2)ROOT用户.bash_profile">>~/.bash_profile
su -
echo "export ORACLE_BASE=/oracle">>~/.bash_profile
echo "export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db">>~/.bash_profile
echo "export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs">>~/.bash_profile
echo "export PATH=$PATH:$ORA_CRS_HOME/bin">>~/.bash_profile
9.配置/etc/hosts网络文件
cp /etc/hosts /etc/hosts.back
echo "192.168.56.101 rac1">>/etc/hosts
echo "192.168.56.111 rac1-vip">>/etc/hosts
echo "10.10.10.101 rac1-priv">>/etc/hosts
echo "192.168.56.102 rac2">>/etc/hosts
echo "192.168.56.112 rac2-vip">>/etc/hosts
echo "10.10.10.102 rac2-priv">>/etc/hosts
10.节点间建立SSH 用户等效项
1)在各节点创建RAS与DSA密钥
su - oracle
mkdir ~/.ssh
chmod 700 ~/.ssh
ssh-keygen -t rsa
注：三次回车。
ssh-keygen -t dsa
注：三次回车。
2)在欲进行RAC安装OUI的节点上，添加密钥到授权密钥文件authorized_keys中
$ssh rac1 cat ~/.ssh/id_rsa.pub>>~/.ssh/authorized_keys
$ssh rac1 cat ~/.ssh/id_dsa.pub>>~/.ssh/authorized_keys
$ssh rac2 cat ~/.ssh/id_rsa.pub>>~/.ssh/authorized_keys
$ssh rac2 cat ~/.ssh/id_dsa.pub>>~/.ssh/authorized_keys
$chmod 600 ~/.ssh/authorized_keys
3)拷贝副本到其它节点对应目录下并授权
节点一：
$scp ~/.ssh/authorized_keys rac2:/home/oracle/.ssh/
节点二：
$chmod 600 ~/.ssh/authorized_keys
4)在OUI节点上测试SSH等效性
$ssh rac1 hostname
$ssh rac2 hostname
注：如果无需输入密码就出现主机名，说明SSH配置成功。
11.配置hangcheck timer内核模块
echo "options hangcheck-timer hangcheck_tick=30 hangcheck_margin=180">>/etc/modprobe.conf
echo "modprobe hangcheck_timer">>/etc/rc.d/rc.local
12.配置两节点LINUX操作系统时间同步<视情况定是否需要>
1)在节点一进行如下操作
cp /etc/ntp.conf /etc/ntp.conf.back
echo "restrict 10.1.120.0 mask 255.255.255.0 nomodify notrap">>/etc/ntp.conf
service ntpd start
2)在节点二进行如下操作
#crontab -e
1-59 * * * * ntpdate 10.1.120.201
13.在其中一个节点配置集群注册表OCR、表决磁盘voting共享LV
1)创建一个分区
fdisk /dev/sdd
n
p
t
8e
w
2)创建一个pv
pvcreate /dev/sdd1
pvscan
3)创建一个vg
vgcreate crsvg /dev/sdd1
vgscan
注：vgcreate datavg /dev/sdc1 /dev/sdd1 /dev/sde1
4)创建db所需的lv
lvcreate -L 300M -n lvocr1 crsvg
lvcreate -L 300M -n lvocr2 crsvg
lvcreate -L 120M -n lvvoting1 crsvg
lvcreate -L 120M -n lvvoting2 crsvg
lvcreate -L 120M -n lvvoting3 crsvg
lvcreate -L 20M -n lvasmpwd crsvg
lvscan
5)重启所有节点，加载共享磁盘信息
#reboot
6)配置lv关联至raw
cp /etc/sysconfig/rawdevices /etc/sysconfig/rawdevices.back
echo "/dev/raw/raw1 /dev/crsvg/lvocr1">>/etc/sysconfig/rawdevices
echo "/dev/raw/raw2 /dev/crsvg/lvocr2">>/etc/sysconfig/rawdevices
echo "/dev/raw/raw3 /dev/crsvg/lvvoting1">>/etc/sysconfig/rawdevices
echo "/dev/raw/raw4 /dev/crsvg/lvvoting2">>/etc/sysconfig/rawdevices
echo "/dev/raw/raw5 /dev/crsvg/lvvoting3">>/etc/sysconfig/rawdevices
echo "/dev/raw/raw6 /dev/crsvg/lvasmpwd">>/etc/sysconfig/rawdevices
/sbin/service rawdevices restart
7)配置raw属主
cp /etc/rc.local /etc/rc.local.back
echo "chown oracle:dba /dev/raw/raw[0-9]">>/etc/rc.local
echo "chmod 660 /dev/raw/raw[0-9]">>/etc/rc.local
dd if=/dev/zero of=/dev/raw/raw1 bs=8192k count=3000
dd if=/dev/zero of=/dev/raw/raw2 bs=8192k count=3000
dd if=/dev/zero of=/dev/raw/raw3 bs=8192k count=1200
dd if=/dev/zero of=/dev/raw/raw4 bs=8192k count=1200
dd if=/dev/zero of=/dev/raw/raw5 bs=8192k count=1200
dd if=/dev/zero of=/dev/raw/raw6 bs=8192k count=200
8)查看相前raw的信息
raw -qa
9)重启所有节点，加载raw映射信息
#reboot
14.主节点安装开始
$export LANG=en_US
$export DISPLAY=192.168.108.1:0.0 --本机IP地址，将图形界面引到本机
$ ./runInstaller -ignoreSysPrereqs
15.BUG
1)在最后的节点运行root.sh脚本时报如下错误——
Oracle CRS stack installed and running under init(1M)
Running vipca(silent) for configuring nodeapps
/home/oracle/crs/oracle/product/10/crs/jdk/jre//bin/java: error while loading
shared libraries: libpthread.so.0: cannot open shared object file:
No such file or directory
解决办法：
在安装最后，运行root.sh脚本之前，修改下列文件
<CRS_HOME>/bin/vipca
<CRS_HOME>/bin/srvctl
<RDBMS_HOME>/bin/srvctl
<ASM_HOME>/bin/srvctl
中的内容
***VIPCA*********************************************************************
if [ "$arch" = "i686" -o "$arch" = "ia64" -o "$arch" = "x86_64" ]
then
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
fi
#增加如下内容
unset LD_ASSUME_KERNEL <<<== Line to be added
*****************************************************************************
***SRVCTL********************************************************************
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
#增加如下内容
unset LD_ASSUME_KERNEL <<<== Line to be added
*****************************************************************************
修改完成后，在二节点上手动运行./vipca，配置完成后关闭图形界面。
2）在最后节点运行vipca时，报如下错误——
Error 0(Native: listNetInterfaces:[3])
[Error 0(Native: listNetInterfaces:[3])]
解决办法：
<CRS_HOME>/bin # ./oifcfg setif -global eth0/192.168.56.0:public
<CRS_HOME>/bin # ./oifcfg setif -global eth1/172.10.10.0:cluster_interconnect
<CRS_HOME>/bin # ./oifcfg getif
eth0 192.168.56.0 global public
eth1 172.10.10.0 global cluster_interconnect
<CRS_HOME>/bin # ./oifcfg iflist
eth0 192.168.56.0
eth1 172.10.10.0
15.禁止/启用 CRS跟随操作系统自动启动
/etc/init.d/init.crs disable
/etc/init.d/init.crs enable
注：启动CRS crsctl start crs
亦可以——
/etc/init.d/init.cssd start
/etc/init.d/init.crs start
评论暂时关闭
