rac2-private ip

192.168.2.107

 

二.配置hostnamehosts文件两台都需要设置

172.20.0.25 rac1:

[root@localhost ~]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=rac1

172.20.0.26 rac2

[root@localhost ~]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=rac2

 

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

172.20.0.25 rac1

172.20.0.186 rac1-vip

192.168.2.112 rac1-priv

172.20.0.26 rac2

172.20.0.189 rac2-vip

192.168.2.107 rac2-priv

172.20.0.174 scan-ip

三.关闭防火墙,NTP服务,关闭selinux

rac1rac2都需要关闭

 

[root@rac1 ~]# vi /etc/sysconfig/selinux

SELINUX=disabled

这里需要重启生效

[root@rac1 ~]# getenforce

disabled

[root@rac1 ~]#/etc/init.d/iptables stop

[root@rac1 ~]# chkconfig iptables off

[root@rac1 ~]# chkconfig ntpd off

四.创建必要的用户、组和目录,并授权

两个节点rac1rac2都需要创建,这里只演示rac1上面的操作。

[root@rac1 ~]# /usr/sbin/groupadd -g 1000 oinstall

[root@rac1 ~]# /usr/sbin/groupadd -g 1020 asmadmin

[root@rac1 ~]# /usr/sbin/groupadd -g 1021 asmdba

[root@rac1 ~]# /usr/sbin/groupadd -g 1022 asmoper

[root@rac1 ~]# /usr/sbin/groupadd -g 1031 dba

[root@rac1 ~]# /usr/sbin/groupadd -g 1032 oper

[root@rac1 ~]# useradd -d /opt/grid -u 1100 -g oinstall  -G asmadmin,asmdba,asmoper,oper,dba grid

[root@rac1 ~]# useradd -d /opt/oracle -u 1101 -g  oinstall -G dba,asmdba,oper oracle

[root@rac1 ~]# passwd oracle

Changing password for user oracle.

New password:

BAD PASSWORD: it is based on a dictionary word

BAD PASSWORD: is too simple

Retype new password:

passwd: all authentication tokens updated successfully.

[root@rac1 ~]# passwd grid

Changing password for user grid.

New password:

BAD PASSWORD: it is too short

BAD PASSWORD: is too simple

Retype new password:

passwd: all authentication tokens updated successfully.

[root@rac1 ~]# mkdir -p /u01/app/11.2.0/grid

[root@rac1 ~]# mkdir -p /u01/app/grid

[root@rac1 ~]# mkdir /u01/app/oracle

[root@rac1 ~]# chown -R grid:oinstall /u01

[root@rac1 ~]# chown oracle:oinstall /u01/app/oracle

[root@rac1 ~]# chmod -R 775 /u01/

[root@rac1 ~]#

. 节点配置检查

查看内存和swap大小,内存大小:至少2.5GB

root@rac1 ~]# grep MemTotal /proc/meminfo

MemTotal:        8061904  kB

[root@rac1 ~]# grep SwapTotal /proc/meminfo

SwapTotal:        3145720 kB

[root@rac1 ~]#

 

六.参数文件修改

1)内核参数设置

[root@rac1  ~]# vi /etc/sysctl.conf

#  Controls the maximum shared segment size, in bytes

kernel.shmmax  = 68719476736(已有)物理内存的1/2(M)*1024*1024

 

#  Controls the maximum number of shared memory segments, in pages

kernel.shmall  = 4294967296(已有)

#oracle  setting

fs.aio-max-nr  = 1048576

fs.file-max  = 6815744

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  = 1048576

 

#/sbin/sysctl -p 执行该命令,使修改生效

 

[root@rac1  ~]# /sbin/sysctl -p

2)配置oraclegrid用户的shell限制 

[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

3)配置login 

[root@rac1  ~]# vi /etc/pam.d/login
 session required pam_limits.so

七.安装所需的依赖包

 

yum -y install binutils  compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++

yum -y install glibc glibc-common  glibc-devel glibc-headers ksh libaio libaio-devel

yum -y install libgcc libstdc++  libstdc++-devel make numactl-devel sysstat unixODBC unixODBC-devel

yum install libcap

八.添加软连接

 

[root@rac1 ~]# cd /lib64

ln -s libcap.so.2 libcap.so.1

九.配置gridoracle用户环境变量

Oracle_sid需要根据节点不同进行修改 

[root@rac1  ~]# su - grid 
 [grid@rac1 ~]$ vi .bash_profile

export  TMP=/tmp

export  TMPDIR=$TMP

export  ORACLE_SID=+ASM1  # RAC1

export  ORACLE_SID=+ASM2  # RAC2

export  ORACLE_BASE=/u01/app/grid

export  ORACLE_HOME=/u01/app/11.2.0/grid

export  PATH=/usr/sbin:$PATH

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

umask  022


需要注意的是ORACLE_UNQNAME是数据库名,创建数据库时指定多个节点是会创建多个实例,ORACLE_SID指的是数据库实例名

[root@rac1  ~]# su - oracle 
 [oracle@rac1 ~]$ vi .bash_profile

export  TMP=/tmp

export  TMPDIR=$TMP

export  ORACLE_SID=orcl1  # RAC1

export  ORACLE_SID=orcl2  # RAC2

export  ORACLE_UNQNAME=orcl

export  ORACLE_BASE=/u01/app/oracle

export  ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export  TNS_ADMIN=$ORACLE_HOME/network/admin

export  PATH=/usr/sbin:$PATH

export  PATH=$ORACLE_HOME/bin:$PATH

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

$ source .bash_profile使配置文件生效

十.手工配置grid用户互信

配置过程如下:

各节点生成Keys:

配置过程如下:

各节点生成Keys:

[root@rac1  ~]# su - grid

[grid@rac1  ~]$ mkdir ~/.ssh

[grid@rac1  ~]$ chmod 700 ~/.ssh

[grid@rac1  ~]$ ssh-keygen -t rsa

[grid@rac1  ~]$ ssh-keygen -t dsa

[root@rac2  ~]# su - grid

[grid@rac2  ~]$ mkdir ~/.ssh

[grid@rac2  ~]$ chmod 700 ~/.ssh

[grid@rac2  ~]$ ssh-keygen -t rsa

[grid@rac2  ~]$ ssh-keygen -t dsa

 

在节点1上进行互信配置:

[grid@rac1  ~]$ touch ~/.ssh/authorized_keys

[grid@rac1  ~]$ cd ~/.ssh

[grid@rac1  .ssh]$ ssh rac1 cat ~/.ssh/id_rsa.pub >> authorized_keys

[grid@rac1  .ssh]$ ssh rac2 cat ~/.ssh/id_rsa.pub >> authorized_keys

[grid@rac1  .ssh]$ ssh rac1 cat ~/.ssh/id_dsa.pub >> authorized_keys

[grid@rac1  .ssh]$ ssh rac2 cat ~/.ssh/id_dsa.pub >> authorized_keys

 

在rac1把存储公钥信息的验证文件传送到rac2上

[grid@rac1  .ssh]$ pwd

/home/grid/.ssh

[grid@rac1  .ssh]$ scp authorized_keys rac2:‘pwd‘

grid@rac2‘s  password:

authorized_keys  100% 1644 1.6KB/s 00:00

 

设置验证文件的权限

在每一个节点执行:

$  chmod 600 ~/.ssh/authorized_keys

 

启用用户一致性

在你要运行OUI的节点以grid用户运行(这里选择rac1):

[grid@rac1  .ssh]$ exec /usr/bin/ssh-agent $SHELL

[grid@rac1  .ssh]$ ssh-add

Identity  added: /home/grid/.ssh/id_rsa (/home/grid/.ssh/id_rsa)

Identity  added: /home/grid/.ssh/id_dsa (/home/grid/.ssh/id_dsa)

 

验证ssh配置是否正确

以grid用户在所有节点分别执行:

ssh  rac1 date

ssh  rac2 date

ssh  rac1-priv date

ssh  rac2-priv date

 

如果不需要输入密码就可以输出时间,说明ssh验证配置成功。必须把以上命令在两个节点都运行,每一个命令在第一次执行的时候需要输入yes。

如果不运行这些命令,即使ssh验证已经配好,安装clusterware的时候也会出现错误:

The  specified nodes are not clusterable

因为,配好ssh后,还需要在第一次访问时输入yes,才算是真正的无障碍访问其他服务器。

 

需要注意的是生成密钥时不设置密码,授权文件权限为600,同时需要两个节点互相ssh通过一次。

十一.配置裸盘

使用asm管理存储需要裸盘,前面配置了共享硬盘到两台主机上。配置裸盘的方式有两种(1oracleasm添加

2/etc/udev/rules.d/60-raw.rules配置文件添加(字符方式帮绑定udev)

采用第二种

fdisk /dev/sdb

Command (m forhelp): n

Command action

   e   extended

   p   primary partition (1-4)

p

Partition number (1-4): 1

…….

这里我分了三个区:OCR(投票盘),DATA(数据文件)),FAR(快速恢复区)

最后 w 命令保存更改

partx -a /dev/sdb

 

分别在两个节点创建裸设备映射(两个节点都要编辑)(两个节点都要编辑)

 

[root@rac1 rules.d]# vi  /etc/udev/rules.d/60-raw.rules

# Enter raw device bindings here.

#

# An example would be:

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

# to bind /dev/raw/raw1 to /dev/sda, or

#    ACTION=="add", ENV{MAJOR}=="8",  ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"

# to bind /dev/raw/raw2 to the device  with major 8, minor 1.

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

ACTION=="add",  KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add",  KERNEL=="sdb3", RUN+="/bin/raw /dev/raw/raw3 %N"

KERNEL=="raw[1-3]",OWNER="grid",GROUP="asmadmin"  MODE="660"

 

启动并查看裸盘

[root@rac1 ~]# start_udev

Starting udev:                                              [  OK  ]

[root@rac1 ~]# ll /dev/raw/

total 0

crw-rw---- 1 grid asmadmin 162, 1 Apr 13  13:51 raw1

crw-rw---- 1 grid asmadmin 162, 2 Apr 13  13:51 raw2

crw-rw---- 1 grid asmadmin 162, 3 Apr 13  13:51 raw3

crw-rw---- 1 root disk     162, 0 Apr 13 13:51 rawctl

 

[root@rac1 rules.d]# raw -qa

/dev/raw/raw1:       bound to major 8, minor 17

/dev/raw/raw2:       bound to major 8, minor 18

/dev/raw/raw3:       bound to major 8, minor 19

查看裸设备的主从设备号

[root@rac1 rules.d]# ls -l /dev/raw/

total 0

crw-rw---- 1 grid asmadmin 162, 1  Aug  5 12:44 raw1

crw-rw---- 1 grid asmadmin 162, 2  Aug  5 12:44 raw2

crw-rw---- 1 grid asmadmin 162, 3  Aug  5 12:44 raw3

 

节点2强制刷新

[root@rac2 rules.d]# partprobe

[root@rac2 ~]# start_udev

Starting udev:                                              [  OK  ]

[root@rac1 rules.d]# raw -qa

/dev/raw/raw1:       bound to major 8, minor 17

/dev/raw/raw2:       bound to major 8, minor 18

/dev/raw/raw3:       bound to major 8, minor 19

查看裸设备的主从设备号

[root@rac1 rules.d]# ls -l /dev/raw/

total 0

crw-rw---- 1 grid asmadmin 162, 1  Aug  5 12:44 raw1

crw-rw---- 1 grid asmadmin 162, 2  Aug  5 12:44 raw2

crw-rw---- 1 grid asmadmin 162, 3  Aug  5 12:44 raw3

 

十二.grid安装

rac1grid软件目录下执行runcluvfy.sh命令开始预安装检查:

grid下解压grid,执行预安装检查。

[grid@rac1  ~]$ cd grid/

[grid@rac1  grid]$ ls
