实验拓扑

服务器	连接状态	网卡名称	IP	网卡模式
rac1	VMnet8	eth0	192.168.1.101	公有
rac1	VMnet1	eth1	10.10.0.1	私有
rac2	VMnet8	eth0	192.168.1.102	公有
rac2	VMnet1	eth1	10.10.0.2	私有

第一部分，系统配置

修改主机名

[root@hostname ~]vim /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=rac1

修改hosts文件

[root@rac1 ~]# vim /etc/hosts

192.168.1.101   rac1
192.168.1.102   rac2
10.10.0.1           rac1-priv
10.10.0.2           rac2-priv
192.168.1.103   rac1-vip
192.168.1.104   rac2-vip
192.168.1.110   rac-scan

禁用防火墙

[root@rac1 ~]# service iptables stop
[root@rac1 ~]# chkconfig iptables off

禁用selinux

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

SELINUX=disabled

修改/etc/pam.d/login

[root@rac1 ~]# vim /etc/pam.d/login

session required pam_limits.so

修改/etc/profile

[root@rac1 ~]# vim /etc/profile

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

修改/etc/csh.login

[root@rac1 ~]# vim /etc/csh.login

if ( /$USER == "oracle" || /$USER == "grid" ) then
limit maxproc 16384
limit descriptors 65536
endif

修改/etc/sysctl.conf

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

fs.aio-max-nr = 1048576
fs.file-max = 6815744
#kernel.shmall = 2097152
#kernel.shmmax =42950000000
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 ~]# sysctl -p

为用户设置资源限制

[root@rac1 ~]# vim /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

配置CTSS
使用集群时间同步服务在集群中提供同步服务，需要卸载网络时间协议 (NTP) 及其配置。要停用 NTP 服务，必须停止当前的 ntpd 服务，从初始化序列中禁用该服务，并删除 ntp.conf 文件。

[root@rac1 ~]# /sbin/service ntpd stop
[root@rac1 ~]# chkconfig ntpd off
[root@rac1 ~]# mv /etc/ntp.conf /etc/ntp.conf.original
[root@rac1 ~]# rm /var/run/ntpd.pid

创建用户和组

[root@rac1 ~]# groupadd -g 501 oinstall
[root@rac1 ~]# groupadd -g 502 asmadmin
[root@rac1 ~]# groupadd -g 503 asmdba
[root@rac1 ~]# groupadd -g 504 asmoper
[root@rac1 ~]# groupadd -g 505 dba
[root@rac1 ~]# groupadd -g 506 oper
[root@rac1 ~]# useradd -m -u 1100 -g oinstall -G asmadmin,asmdba,asmoper -d /home/grid -s /bin/bash -c "Grid Infrastructure Owner" grid
[root@rac1 ~]# useradd -m -u 1101 -g oinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle

创建目录及授权

[root@rac1 ~]# mkdir -p /u01/app/grid
[root@rac1 ~]# mkdir -p /u01/app/11.2.0/grid
[root@rac1 ~]# chown -R grid:oinstall /u01
[root@rac1 ~]# mkdir -p /u01/app/oracle
[root@rac1 ~]# chown oracle:oinstall /u01/app/oracle
[root@rac1 ~]# chmod -R 775 /u01

修改用户环境变量
