2节点RAC搭建

原创 Oracle 作者：hzplslxy 时间：2017-09-15 20:17:51 0 删除 编辑
  1. 规划：两节点rac

系统：redhat 6.3

 


节点1

节点2

主机名

rac1

Rac2

eth0：Public IP

192.168.2.101

192.168.2.102

eth0：VIP

192.168.2.103

192.168.2.104

eth1：Private IP

192.168.1.101

192.168.1.102

2. 硬件环境

项目

要求

检查方法

内存

只安装grid 内存至少要1.5G
安装grid和RDBMS至少2.5G

Grip MemTotal/proc/meminfo

Swap空间

取决于节点的物理内存数
物理内存<2G:1.5*物理内存
物理内存2G-16G:=物理内存
物理内存>16G:16G

/sbin/swapon-s

临时空间

/tmp>1GB


Grid home目录空间

Oracle建议5.5G，如果考虑到补丁，log文件，定义到10GB


ASM voting/OCR

这个文件取决于选择的冗余方式
External redundancy：OCR,votingfile都按照每个文件300M空间准备
Normal redundancy：有3个votingfile和2个OCR所以一共需准备1.5G，放在3个failure group中的三个单独磁盘上
High redundancy：有5个votingfile和三个OCR
，共需准备2.4G而且是5个failure group中的5个单独磁盘上。


4. 安装虚拟机

略

5. 配置

  • 内核参数：

[root@rac1 ~]# vi /etc/sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 4294967295

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

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 = 1048586

[root@rac1 ~]# /sbin/sysctl -p

  • 安全限制调整

[root@rac1 ~]# vi /etc/security/limits.conf

oracle              soft    nproc   2047

oracle              hard    nproc   16384

oracle              soft    nofile  1024

oracle              hard    nofile  65536

oracle              soft    stack   10240

 

grid              soft    nproc   2047

grid              hard    nproc   16384

grid              soft    nofile  1024

grid              hard    nofile  65536

grid              soft    stack   10240

  • hosts文件设置

[root@RACDB1 ~]# vi /etc/hosts

##Public Network - (eth0)

192.168.2.101  rac1

192.168.2.102  rac2

##Private Interconnect - (eth1)

192.168.1.101  rac1-priv

192.168.1.102  rac2-priv

##Public Virtual IP (VIP) addresses - (eth0)

192.168.2.103  rac1-vip

192.168.2.104  rac2-vip

##scan IP

192.168.2.110 rac-scan

设置IP地址

[root@rac1 network-scripts]# pwd

/etc/sysconfig/network-scripts

[root@rac3 network-scripts]# cat ifcfg-eth0

# Intel Corporation 82540EM Gigabit Ethernet Controller

DEVICE=eth0

BOOTPROTO=static

IPADDR=192.168.2.107

NETMASK=255.255.255.0

GETWAY=192.168.2.1

ONBOOT=yes

6. 创建用户和组

groupadd -g 501 oinstall

groupadd -g 502 dba

groupadd -g 503 oper

groupadd -g 504 asmadmin

groupadd -g 505 asmdba

groupadd -g 506 asmoper

useradd -u 501 -d /home/grid -g oinstall -G asmadmin,asmdba,asmoper grid

passwd grid

useradd -u 502 -d /home/oracle -g oinstall -G dba,asmdba,oper oracle

passwd oracle

7.   创建存放安装目录

mkdir /soft

chown -R oracle:oinstall /soft

chmod -R 775 /soft

8.   创建目录

mkdir -p /u01/app/11.2.0/grid

mkdir -p /u01/app/grid

mkdir -p /u01/app/oracle

mkdir -p /u01/app/oracle/11.2.0

chown -R oracle:oinstall /u01

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

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

chmod -R 775 /u01/

9. 设置环境变量

  • 设置oracle用户环境变量

su - oracle

vi .bash_profile

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

export ORACLE_SID=racdb1

export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin

  • 设置grid用户环境变量

su - grid

vi .bash_profile

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/11.2.0/grid

export ORACLE_SID=+ASM1

export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH

10.安装rpm包

  • 安装YUM

root用户下

vi /etc/yum.repos.d/yum-el5.repo

[oel6]

name = Enterprise Linux 6.3 DVD

baseurl=file:///mnt/

gpgcheck=0

enabled=1

[root@rac1 ~]# mount /dev/cdrom /mnt

[root@rac1 ~]# yum install binutils.x86_64 compat-libcap1.x86_64 compat-libstdc++-33.x86_64 compat-libstdc++-33.i686 gcc.x86_64 gcc-c++.x86_64 glibc.i686 glibc.x86_64 glibc-devel.x86_64 glibc-devel.i686 ksh.x86_64 libgcc.i686 libgcc.x86_64 libstdc++.x86_64 libstdc++.i686 libstdc++-devel.x86_64 libstdc++-devel.i686 libaio.x86_64 libaio.i686 libaio-devel.x86_64 libaio-devel.i686 make.x86_64 sysstat.x86_64 unixODBC.x86_64 unixODBC.i686 unixODBC-devel.x86_64 unixODBC-devel.i686

11.复制虚拟机

修改主机名：vi /etc/sysconfig/network

修改MAC地址和ip地址

或重新生成网络文件/etc/udev/rule.d

修改oracle和grid用户的环境变量

关闭防火墙

12.创建共享磁盘

关闭RAC1,RAC1两个虚拟机

  • 在windows的cmd下执行：

E:

cd E:\vm\server\RAC1
