1.环境信息准备
注意： 在配置网络时，Oracle RAC的每个节点必须具有至少两个以上的网卡，一张网卡对外提供网络服务，另一张网卡用于各个节点间的通信和心跳检测等。在配置RAC集群的网卡时，如果节点1的公共接口是eth0，则所有节点的公共接口必须是eth0。（配置私有网口时也必须一致）另外，每个节点的主机名必须符合RFC 952标准，不允许使用下划线。对于Oracle 11G RAC双节点说，Oracle要求我们至少有7个ip地址，Public IP、Virtual IP和Scan IP在同一个网段下，Private IP在另一个网段中。
| 主机名 | rac1 | rac2 |
| Public IP | 10.186.63.52 | 10.186.63.53 |
| Private IP | 10.186.202.2 | 10.186.202.3 |
| Virtual ip | 10.186.63.203 | 10.186.63.204 |
| Scan ip | 10.186.63.205 | |
| NFS ip | 10.186.63.26 | |
2.共享存储规划
| 磁盘名 | 磁盘数量 | 磁盘大小 | 冗余模式 |
|---|---|---|---|
| OCR | 3 | 10G/个 | Normal |
| DATA | 1 | 50G | External |
| FRA | 1 | 20G | External |
3.安装步骤
3.1主机配置
#修改主机名
#10.186.63.52
hostnamectl set-hostname rac1
#10.186.63.53
hostnamectl set-hostname rac2
#修改/etc/hosts文件 rac1和rac2一样文件末加入如下内容
vi /etc/hosts
#Public ip
10.186.63.52 rac1
10.186.63.53 rac2
# Private ip
10.186.202.2 rac1priv
10.186.202.3 rac2priv
# Virtual ip
10.186.63.203 rac1vip
10.186.63.204 rac2vip
# Scan ip
10.186.63.205 racscan
#NFS
10.186.63.26 nfs
#刷新
exec bash
#查看是否生效，注意hostname不生效可能导致安装失败
cat /etc/hostname 3.2创建用户组和用户
groupadd oinstall -g 500
groupadd dba -g 501
groupadd oper -g 502
groupadd asmadmin -g 2003
groupadd asmdba -g 2004
groupadd asmoper -g 2005
useradd -u 500 -g oinstall -G dba,oper,asmdba,asmadmin,asmoper -d /home/oracle oracle
useradd -u 2001 -g oinstall -G asmadmin,asmdba,asmoper,dba -d /home/grid grid
echo oracle | passwd --stdin oracle &&\
echo grid | passwd --stdin grid3.3 禁用firewalld和selinux
systemctl stop firewalld
systemctl disable firewalld
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 03.4禁用 avahi-daemon服务
systemctl stop avahi-daemon
systemctl disable avahi-daemon
echo 'NOZEROCONF=yes' >> /etc/sysconfig/network
3.5关闭透明大页和NUMA
#查看透明页情况
cat /sys/kernel/mm/transparent_hugepage/enabled
#结果显示
[always] madvise never 表示开启了透明页
#关闭透明大页
cat <<EOF>> /etc/rc.d/rc.local
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
EOF
授权
chmod +x /etc/rc.d/rc.local
#关闭numactl(关闭交换页面)
sed -i 's/quiet/quiet transparent_hugepage=never numa=off/' /etc/default/grub
#生成启动规则
grub2-mkconfig -o /boot/grub2/grub.cfg
#重启服务器
reboot3.6修改nsswitch.conf
nsswitch.conf保存的是域名检索顺序，在一些系统配置中，NIS(Network Information system)可能会引起SCAN域名解析异常
sed -i "s/^hosts: files dns myhostname/hosts: files dns myhostname nis/g" /etc/nsswitch.conf3.7调整磁盘调度模式
为了获得Oracle ASM的最佳性能，Oracle建议使用Deadline I/O调度
#查看当前系统的I/O调度方法
cat /sys/block/sda/queue/scheduler
noop [deadline] cfq #表示是使用deadline I/O调度
#如果磁盘调度为noop或者是cfq，则需要修改为deadline,通过如下命令处理
#永久的更改I/O调度方法：修改内核引导参数，加入elevator=调度程序名
grubby --update-kernel=ALL --args="elevator=deadline"
#需要重启生效
reboot
#再次查看当前系统的I/O调度方法
cat /sys/block/sda/queue/scheduler
结果显示：
noop [deadline] cfq #此时已经是deadline了3.8禁用NTP服务
Oracle会在安装时检测是否有NTP服务，如果有，则会认为你的服务器是使用NTP来同步节点时间的，会将自身的CTSS服务配置成观察状态；如果检测到没有NTP服务，则会使用CTSS服务来同步时间。CTSS服务会将安装Grid软件的那台来作为主节点，然后让集群的其他节点时间与主节点的时间进行同步。
禁用NTP服务，使用Oracle的CTSS服务来同步节点的时间,如果时间和时间差异比较大，则将其修改为主节点的时区，并将时间调整到与主节点相近的时间，后续CTSS服务会修正时间
#停止NTP服务并关闭开机自启
systemctl stop ntpd && systemctl disable ntpd && rm -fr /etc/ntp.conf3.9 配置内核参数
cat <<EOF>> /etc/sysctl.conf
fs.file-max = 6815744

sysctl -p配置注解：
配置讲解：
(1)fs.file-max：最大打开文件数
(2)kernel.shmall：共享内存的总量，8G内存设置：(8*1024*1024)KB/4KB=2097152
(3)kernel.shmmax：最大共享内存的段大小，一般设置为服务器的80%内存总大小：物理内存大小*1024*1024*1024-1,必须要大于等于SGA，
比如8G=oracle 内存8G*0.8=6.4 (SGA=6.4*0.8=5.12+PGA=6.4*0.2）---->=SGA=5*1024*1024*1024
oracle 内存设置： oracle 内存=物理内存*40%-80%，生产服务器内存比较大可以设置为60%，小可以设置为80%
物理内存的80%， 物理内存的40%
oracle = SGA (80%)+ PGA(20%)
SGA=物理内存的80%的80%=8*0.8*0.8=5
PGA=物理内存的80%的20%=8*0.8*0.2=1.2
shmmax=5*1024*1024*1024
shmall=shmmax/PAGESIZE
nr_hugepages=SGA/2+100~500=2600
shmall参数：控制共享内存页数： = shmmax/PAGESIZE
getconf PAGESIZE 获取每而大小
shmmni参数：共享内存段最大数量
vm.nr_hugepages:大页，系统内存大于8G，生产一定要设置，设置了大页会让oracle运行得更快
SGA/2M+200
(4)net.ipv4.ip_local_port_range：可使用的ipv4端口范围
如果服务器只运行单个实例(数据库)，可以参考下下面的建议值
内存为12G
kernel.shmall = 3145728
kernel.shmmax = 12884901887
内存为16G
kernel.shmall = 4194304

[oracle@rac2 ~]$4.配置NFS共享存储(10.186.63.26 nfs)
4.1创建lvm（10.186.63.26 nfs服务端操作）
vgcreate vg01 /dev/vdb
vgcreate vg02 /dev/vdc
lvcreate -n lv01 -l 100%free vg01
lvcreate -n lv02 -l 100%free vg02
注意：lvcreate -n lv02 -l 100%free vg02&vg01创建的时候选择分配所有空间，不然后面安装grid执行root.sh时节点2可能会重新创建表决盘而无法加入集群。
4.2挂载共享目录
mkdir -p /ora_data
mkdir -p /ora_arch
mkfs.xfs /dev/vg01/lv01
mkfs.xfs /dev/vg02/lv02
mount /dev/vg01/lv01 /ora_data
mount /dev/vg02/lv02 /ora_arch
vi /etc/fstab
/dev/vg01/lv01 /ora_data xfs defaults 0 0
/dev/vg02/lv02 /ora_arch xfs defaults 0 0
mount -a
/ora_data存放oracle数据，ora_arch存放归档日志
#挂载后如图：
4.3配置NFS共享目录，让目标节点可以识别到
yum install -y nfs-utils rpcbind
vi /etc/exports
#rac1\rac2-ASM
/ora_data 10.186.63.52/32(rw,sync,no_wdelay,insecure,no_root_squash)
/ora_data 10.186.63.53/32(rw,sync,no_wdelay,insecure,no_root_squash)
#ra1\rac2-arch
/ora_arch 10.186.63.52/32(rw,sync,no_wdelay,insecure,no_root_squash)
/ora_arch 10.186.63.53/32(rw,sync,no_wdelay,insecure,no_root_squash)
systemctl start nfs-server.service && systemctl enable nfs-server.service
systemctl status nfs-server
exportfs -v
10.186.63.52&53为oracle rac两个节点ip
#配置好后截图如下：

5.上传安装包并解压(rac1节点执行即可)
unzip p13390677_112040_Linux-x86-64_1of7.zip -d /u01/software
unzip p13390677_112040_Linux-x86-64_2of7.zip -d /u01/software
unzip p13390677_112040_Linux-x86-64_3of7.zip -d /u01/software
chown -R grid:oinstall /u01/software/grid
chown -R oracle:oinstall /u01/software/database6.安装依赖包（rac1&&rac2）
yum -y install gcc* compat-libstdc* elfutils-libelf-devel* glibc-devel* glibc-headers* libaio-devel* libstdc* ksh* compat-libcap1*
rpm -ivh pdksh-5.2.14-30.x86_64.rpm --force --nodeps
rpm -ivh compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm
# 安装Grid软件带的依赖包
rpm -ivh /u01/software/grid/rpm/cvuqdisk-1.0.9-1.rpm
7.安装前校验(一个节点执行即可)
[grid@rac1 ~]$ cd /u01/software/grid
# 校验
[grid@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose
根据报错调整，重新执行检查
#添加swap
dd if=/dev/zero of=/home/swap bs=8M count=1000
mkswap /home/swap
swapon /home/swap
echo "/home/swap swap swap defaults 0 0" >>/etc/fstab
8.静默安装Grid软件
8.1 grid用户登录rac1进行安装
# 进入响应文件目录
[grid@rac1 grid]$ cd response
# 编辑Grid软件
[grid@rac1 response]$ vim grid_install.rsp
#文件末尾添加如下内容：

# oracle用户进入到响应文件中
[oracle@rac1 ~]$ cd /u01/software/database/response
# 编辑响应文件
[oracle@rac1 response]$ vim db_install.rsp
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oraInventory
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=oper
oracle.install.db.CLUSTER_NODES=rac1,rac2
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
oracle.installer.autoupdates.option=SKIP_UPDATES
10.3静默安装
# 退至上一级目录
[oracle@rac1 response]$ cd ..
# 静默安装
[oracle@rac1 database]$ ./runInstaller -silent -responseFile /u01/software/database/response/db_install.rsp -ignorePrereq
10.4执行root脚本
执行后根据提示的日志文件目录去查看下日志，看是否有报错。
rac2:
/u01/app/oraInventory/orainstRoot.shrac1:
/u01/app/oracle/product/11.2.0/dbhome_1/root.shrac2:
/u01/app/oracle/product/11.2.0/dbhome_1/root.sh11.添加监听至集群中(rac1&rac2)
grid用户登录rac1和rac2执行
su - grid
srvctl status listener
# 添加监听
srvctl add listener
srvctl start listener
srvctl status listener
12.安装数据库
12.1编辑dbca.rsp响应文件
# 进入响应文件目录
[oracle@rac1 ~]$ cd /u01/software/database/response
# 编辑响应文件
[oracle@rac1 response]$ mv dbca.rsp dbca.rsp_bak
[oracle@rac1 response]$ vim dbca.rsp

12.1静默安装(在rac1节点执行即可)
[oracle@rac1 response]$ dbca -silent -responseFile /u01/software/database/response/dbca.rsp
#登录oracle数据库验证是否安装成功（rac1&rac2）
13.检查集群状态
su - grid
crsctl status res -t
