注： 以下配置，没有特殊说明，均在双节点执行
1、网络配置
以rac01为例，两node都要配置
eth0和eth2 做bond0
eth3和eth4 做bond1
Mac地址记录如下：
eth0 : 00:0C:29:12:28:2C
eth2 : 00:0c:29:12:28:36
eth3 : 00:0c:29:12:28:40
eth4 : 00:0c:29:12:28:4a
[root@test-rac01 network-scripts]# cat ifcfg-bond0

2、内核模块加载
[root@rac01 ~]# vi /etc/modprobe.d/dist.conf
添加内容
alias bond0 bonding
alias bond1 bonding
alias scsi_hostadapter2 lpfc
[root@rac01 ~]# vi /etc/modprobe.d/openfwwf.conf
添加内容
options lpfc lpfc_nodev_tmo=30 lpfc_lun_queue_depth=16 lpfc_discovery_threads=32
options hangcheck-timer hangcheck_tick=1 hangcheck_margin=10 hangcheck_reboot=1
options e1000 FlowControl=1
3、关闭sendmail服务
[root@test-rac01 ~]# chkconfig sendmail off
[root@test-rac01 ~]# chkconfig --list | grep sendmail
sendmail 0:off 1:off 2:off 3:off 4:off 5:off 6:off
4、配置hosts文件和DNS
[root@test-rac01 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 test-rac01 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
# Public IP for Oracle 11g RAC
10.109.67.52 rac01.localdomain rac01
10.109.67.53 rac02.localdomain rac02
# Private IP for Oracle 11g RAC
193.168.1.102 rac01pri.localdomain rac01pri
193.168.1.103 rac02pri.localdomain rac02pri
# Virtual IP for Oracle 11g RAC
10.109.67.46 rac01vip.localdomain rac01vip
10.109.67.47 rac02vip.localdomain rac02vip
保证两节点均可以利用host相互通信
配置DNS
[root@rac01 ~]# yum install bind*

5、YUM安装依赖包
[root@rac01 ~]# mount /dev/cdrom /mnt/
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@rac01 ~]# cd /etc/yum.repos.d/
[root@rac01 yum.repos.d]# cp rhel-source.repo rhel-source.repo.bak
[root@rac01 yum.repos.d]# vi rhel-source.repo
修改内容如下
[rhel6.5]
name=Red Hat 6.5
baseurl=file:///mnt/Server
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[root@rac01 yum.repos.d]# yum update

6、修改内核参数
[root@rac01 ~]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
kernel.shmmax = 4398046511104
kernel.shmall = 1073741824
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
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
7、设置Oracle和Grid用户的SHELL限制
[root@rac01 ~]# vi /etc/security/limits.conf
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 131072
grid hard nofile 65536
grid soft stack 10240
grid hard stack 32768
oracle soft nproc 131072
oracle hard nproc 131072
oracle soft nofile 131072
oracle hard nofile 65536
oracle hard nofile 131072
oracle soft nofile 131072
[root@rac02 ~]# vi /etc/pam.d/login
[root@rac01 ~]# cat /etc/security/limits.conf
ession required pam_limits.so
session required /lib64/security/pam_limits.so
[root@rac01 ~]# cat /etc/security/limits.d/90-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
* soft nproc 1024
root soft nproc unlimited
8、关闭防火墙，同步时间
[root@rac02 ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
9、创建用户和组 及相关目录
groupadd oinstall
groupadd dba
groupadd oper
groupadd backupdba
groupadd dgdba
groupadd kmdba
groupadd asmdba
groupadd asmoper
groupadd asmadmin
useradd -g oinstall -G dba,asmadmin,asmdba,asmoper grid
useradd -g oinstall -G dba,oper,backupdba,dgdba,kmdba,asmdba,asmadmin oracle
passwd grid
passwd oracle
mkdir -p /u01/app/12.1.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle/product/12.1.0/db_1
chown -R grid:oinstall /u01
chmod -R 775 /u01/
chown -R oracle:oinstall /u01/app/oracle
10、设置环境变量 grid用户PATH=$PATH:$HOME/bin
[root@rac02 ~]# su - grid
[grid@rac02 ~]$ vi .bash_profile
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/12.1.0/grid
export ORACLE_SID=+ASM
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export DISPLAY=:0.0
umask=022
[root@rac02 ~]# su - oracle
[oracle@rac02 ~]$ vi .bash_profile
PATH=$PATH:$HOME/bin
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/12.1.0/db_1
export ORACLE_SID=orcl2
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export DISPLAY=:0.0
umask=022
export PATH
11、配置ASM
依次安装
oracleasm-support-2.1.8-1.el6.x86_64.rpm
kmod-oracleasm-2.0.6.rh2-2.el6.x86_64.rpm
oracleasmlib-2.0.4-1.el6.x86_64.rpm
对磁盘进行分区(一个节点上执行)
