Oracle 11g RAC 搭建详细步骤

Oracle RAC 搭建步骤详解

前期准备：

数据库:11.2.0.4

OS：Centos 6.8

IP分配：

#publice ip

192.168.180.2 rac1

192.168.180.3 rac2

#private ip

10.10.10.2  rac1-priv

10.10.10.3  rac2-priv

#vip

192.168.180.4 rac1-vip

192.168.180.5 rac2-vip

#scan ip

192.168.180.6 rac-scan

RAC 存储配置：

   OCR_VOTING  3个 4G

   DATA         1个 50G

   FRA_ARC      1个 20G

1. 配置udev（所有节点）

关于RAC 共享存储可参考：http://blog.csdn.net/shiyu1157758655/article/details/56837550

用如下脚本获取绑定脚本：注意这里的 c d e f g是要作为共享的存储的磁盘，要根据自己实际情况修改。

for i in c d e f g ;

do

echo "KERNEL==\"sd*\", BUS==\"scsi\",PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace--device=/dev/\$name\", RESULT==\"`/sbin/scsi_id --whitelisted--replace-whitespace --device=/dev/sd$i`\", NAME=\"asm-disk$i\",OWNER=\"grid\", GROUP=\"asmadmin\",MODE=\"0660\""     >> /etc/udev/rules.d/99-oracle-asmdevices.rules

done

重启start_udev

2. 添加组和用户（所有节点）

groupadd -g 1000 oinstall

groupadd -g 1200 asmadmin

groupadd -g 1201 asmdba

groupadd -g 1202 asmoper

groupadd -g 1300 dba

groupadd -g 1301 oper

useradd -m -u 1100 -g oinstall -Gasmadmin,asmdba,asmoper,dba -d /home/grid-s /bin/bash grid

useradd -m -u 1101 -g oinstall -Gdba,oper,asmdba -d /home/oracle -s/bin/bash oracle

--将用户grid添加到dba组：

[root@rac1 app]# gpasswd -a grid dba

Adding user grid to group dba

--确认用户信息：

[root@rac1 ~]# id oracle

uid=502(oracle)gid=507(oinstall)groups=507(oinstall),502(dba),503(oper),506(asmdba)

[root@rac1 ~]# id grid

uid=1100(grid) gid=507(oinstall)groups=507(oinstall),504(asmadmin),506(asmdba),505(asmoper)

--修改密码：

passwd oracle

passwd grid

3.  禁用防火墙和SELNUX（所有节点）

关闭防火墙：

service iptables status

service iptables stop

chkconfig iptables off

chkconfig iptables –list    

设置/etc/selinux/config 文件，将SELINUX设置为disabled。

[root@rac1 ~]# cat/etc/selinux/config

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

#     enforcing - SELinux securitypolicy is enforced.

#     permissive - SELinux printswarnings instead of enforcing.

#     disabled - No SELinux policyis loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

#     targeted - Targeted processesare protected,

#     mls - Multi Level Securityprotection.

SELINUXTYPE=targeted

4.  配置时间同步(所有节点)

这里我们使用CTSS.所以要停用 NTP 服务，并从初始化序列中禁用该服务，并删除 ntp.conf 文件。以 root 用户身份在两个 OracleRAC 节点上运行以下命令：

[root@rac1 ~]# /sbin/service ntpd stop

Shutting down ntpd: [ OK ]

[root@rac1 ~]# chkconfig ntpd off

[root@rac1 ~]# mv /etc/ntp.conf/etc/ntp.conf.original

[root@rac1 ~]# chkconfig ntpd --list

ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off

还要删除以下文件：

rm /var/run/ntpd.pid

此文件保存了 NTP 后台程序的 pid

5.  创建目录结构（所有节点）

Inventory 目录：/u01/app/oraInventory

ORACLE BASE 目录：/u01/app/oracle

Grid Infrastructure HOME 目录：/u01/app/grid/product/11.2.0/grid_1

RDBMS HOME 目录：/u01/app/oracle/product/11.2.0/db_1

配置相关目录的属主及权限

Inventory 目录：属主，grid:oinstall；权限，775

ORACLE BASE 目录：属主，oracle:oinstall；权限，775

Grid Infrastructure HOME 目录：属主，grid:oinstall；权限，775

RDBMS HOME 目录：属主，oracle:oinstall；权限，775

mkdir -p/u01/app/oraInventory

mkdir -p/u01/app/oracle

mkdir -p/u01/app/grid/product/11.2.0/grid_1

mkdir -p/u01/app/oracle/product/11.2.0/db_1

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

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

[root@rac1 ~]#chown -R grid:oinstall /u01/app/grid/product/12.1.0/grid_1/

[root@rac1 ~]#chown -R oracle:oinstall /u01/app/oracle/product/12.1.0/db_1/

6.  配置主机/etc/hosts 别名（所有节点）

如果需要没有计划采用 DNS 服务器，需要在服务器本地配置服务器主机名与 IP 地址的映射

关系。具体涉及的主要配置文件为：

/etc/hosts

该配置文件主要的配置信息建议如下

    127.0.0.1   localhost  //记住这个一定要加上

#public ip

192.168.180.2  rac1

192.168.180.3  rac2

#private ip

10.10.10.2     rac1-priv

10.10.10.3     rac2-priv

#vip

192.168.180.4  rac1-vip

192.168.180.5  rac2-vip

#scan ip

192.168.180.6  rac-scan

注意：除了本机主机名映射地址条目外，两个节点的/etc/hosts 配置文件需要一致。上述建议

信息中：public ip、virtual ip、scan 为提供服务的 ip；privateip 为心跳私有 ip

7.  配置节点互信机制（所有节点）

需要将 grid 用户、oracle 用户配置好集群节点之间的互信机制。配置集群节点互信机制建议

采用ssh 协议。主要涉及的配置文件有：

$HOME/.ssh/authorized_keys

注意：此文件需要手工创建。

具体可参考：http://blog.csdn.net/shiyu1157758655/article/details/56838603

8.  配置环境变量（所有节点）

需要对 grid 用户、oracle 用户配置好环境变量。

grid 用户的环境变量配置建议如下：

umask 022

PS1='$ORACLE_SID'":"'$PWD'"@"`hostname`">"

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

ORACLE_HOME=/u01/app/grid/product/11.2.0/grid_1; export ORACLE_HOME

ORACLE_SID=+ASM1; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

TMPDIR=/var/tmp; export TMPDIR

NLS_DATE_FORMAT="YYYY/MM/DD hh24:mi:ss"; export NLS_DATE_FORMAT

ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data; export ORA_NLS33

TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN DISPLAY

LIBPATH=$ORACLE_HOME/lib; export LIBPATH

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

Oracle用户的环境变量配置建议如下：

umask 022

PS1='$ORACLE_SID'":"'$PWD'"@"`hostname`">"

ORACLE_BASE=/u01/app/oracle_base; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME

ORACLE_SID=rac1; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

TMPDIR=/var/tmp; export TMPDIR

NLS_DATE_FORMAT="YYYY/MM/DD hh24:mi:ss"; export NLS_DATE_FORMAT

ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data; export ORA_NLS33

TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN DISPLAY

LIBPATH=$ORACLE_HOME/lib; export LIBPATH

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

9.  修改/etc/security/limits.conf（所有节点）

以 root 用户身份，在每个 OracleRAC 节点上，在 /etc/security/limits.conf 文件中添加如下内容，或者执行执行如下命令：

root@rac1 ~]# cat >> /etc/security/limits.conf < 
  
grid soft nproc 2047
 
  
grid hard nproc 16384
 
  
grid soft nofile 1024
 
  
grid hard nofile 65536
 
  
oracle soft nproc 2047
 
  
oracle hard nproc 16384
 
  
oracle soft nofile 1024
 
  
oracle hard nofile 65536
 
  
EOF
 
  
10. 修改/etc/pam.d/login（所有节点）
 
  
在每个 OracleRAC 节点上，在/etc/pam.d/login 文件中添加或编辑下面一行内容：
 
  
[root@rac1 ~]# cat >> /etc/pam.d/login < 
  
session required pam_limits.so
 
  
EOF
 
  
11. 配置系统默认 profile （所有节点）
 
  
确认以下配置加载到系统的默认 profile 中。具体涉及到的主要配置文件如下：
 
  
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
 
  
if [ $SHELL = "/bin/ksh" ]; then
 
  
  ulimit -p 16384
 
  
  ulimit -n 65536
 
  
else
 
  
  ulimit -u 16384 -n 65536
 
  
fi
 
  
 umask 022
 
  
fi
 
  
12. 修改/etc/sysctl.conf（所有节点）
 
  
#vi /etc/sysctl.conf
 
  
kernel.shmmax = 4294967295
 
  
kernel.shmall = 2097152
 
  
kernel.shmmni = 4096
 
  
kernel.sem = 250 32000 100 128
 
  
fs.file-max = 6815744
 
  
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
 
  
fs.aio-max-nr=1048576
 
  
kernel.panic_on_oops=1
 
  
使修改的参数生效：
 
  
[root@rac1 ~]# sysctl -p

点击ok继续安装：
 
  
 
 
  
这里有个报错，我选择忽略掉，貌似没啥影响。
 
  
 
  
到此grid已经安装成功。
 
  
 
 
  
15. 创建ASM磁盘组
 
  
以grid用户登陆，执行asmca
 
  
选择【create】
 
  
 
  
 
  
 
 
  
16. 安装Oracle RDBMS软件
 
  
在创建完磁盘组之后，即可安装RDBMS软件
 
  
注意：安装RDBMS软件，需要使用oracle用户创建
 
  
./runInstaller
 
  
 
  
 
  
 
  
 
 
  
这里仅安装软件
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
 
  
忽略上面2个报错
 
  
 
  
点击安装即可
 
  
 
 
  
17. 创建数据库
 
  
以oracle用户执行dbca
 
  
 
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
  
 
 
  
点击执行即可
 
  
18. 总结
 
  
到此oracle11g rac 安装完成，期间遇到的各种问题，需要耐心的一个个解决。
