二、安装前配置

---

1. 配置网路

[root@localhost ~]# hostname rac1.gavin.com

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

[root@localhost ~]# service network restart

Shutting down interface eth0:                              [  OK  ]

Shutting down loopback interface:                          [  OK  ]

Bringing up loopback interface:                            [  OK  ]

Bringing up interface eth0:  

Determining IP information for eth0... done.               [  OK  ]

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

#Public Host Names

192.168.37.145   rac1.gavin.com rac1

192.168.37.144   rac2.gavin.com rac2



#Private Host Names

192.168.1.145   rac1-priv.gavin.com rac1-priv

192.168.1.144   rac2-priv.gavin.com rac2-priv



#Virtual Host Names

192.168.1.45   rac1-vip.gavin.com rac1-vip

192.168.1.44  rac2-vip.gavin.com rac2-vip

 

 

 

 

 

[root@rac1 ~]# ping rac1.gavin.com

[root@rac1 ~]# ping rac2.gavin.com

 

 

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

OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"

 

 

2. 设置组和用户

[root@rac1 ~]# /usr/sbin/groupadd -g 501 oinstall

[root@rac1 ~]# /usr/sbin/groupadd -g 502 dba

[root@rac1 ~]# /usr/sbin/groupadd -g 504 asmadmin

[root@rac1 ~]# /usr/sbin/groupadd -g 506 asmdba

[root@rac1 ~]# /usr/sbin/groupadd -g 507 asmoper

[root@rac1 ~]# /usr/sbin/useradd -u 501 -g oinstall -G asmadmin,asmdba,asmoper grid

[root@rac1 ~]# /usr/sbin/useradd -u 502 -g oinstall -G dba,asmdba oracle



[root@rac1 ~]# id oracle

uid=502(oracle) gid=501(oinstall) groups=501(oinstall),502(dba),506(asmdba) context=root:system_r:unconfined_t:SystemLow-SystemHigh

[root@rac1 ~]# id grid

uid=501(grid) gid=501(oinstall) groups=501(oinstall),504(asmadmin),506(asmdba),507(asmoper) context=root:system_r:unconfined_t:SystemLow-SystemHigh

 

 

3. 配置共享存储

安装ASMLib库

[root@rac1 ~]# uname -a

Linux rac1.gavin.com 2.6.18-53.el5 #1 SMP Mon Nov 12 02:14:55 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

will be shown in brackets ('[]').  Hitting <ENTER> without typing an

answer will keep that current value.  Ctrl-C will abort.

4. 保护外壳和用户限制配置

[root@rac1 oracleasm]# vi /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

 

 

[root@rac1 oracleasm]# vi /etc/pam.d/login

session    required     pam_limit.s

 

 

 

5. 配置内核参数

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

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 512 x processes

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmen_default = 262144

net.core.wmen_max = 1048576

 

 

 

三、安装Oracle Grid Infrastructure

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

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

# SELINUX= can take one of these three values:

#       disabled - SELinux is fully disabled.

SELINUX=disabled

# SELINUXTYPE= type of policy in use. Possible values are:

#       targeted - Only targeted network daemons are protected.

#       strict - Full SELinux protection.

[root@rac1 oracleasm]# setenforce 0
