1.搭建RAC架构前的准备工作
1.1安装VirtualBox自带的增强功能（与VMware虚拟机的VM Tools功能相仿）
当前系统无法建立内核模块，运行Linux内核头文件：
yum install kernel-devel-2.6.32-431.el6.x86_64
特别注意：设置共享剪切板和拖放的选项是双向，重启虚拟机后，即可复制粘贴文本，拖放文件。
1.2关闭一系列服务
关闭防火墙
service iptables stop（当前关闭，重启无效） chkconfig iptables off（更改文件，重启生效）
关闭网络管理服务
service NetworkManager stop chkconfig NetworkManager off
1.3修改配置文件信息
修改selinux设置
vim /etc/selinux/config
修改内核设置
vim /etc/grub.conf
1.4配置网络：绑定网卡
1.4.1相关概念
Bonding(绑定)是一种Linux系统下的网卡绑定技术，可以把服务器上n个物理网卡在系统内部抽象(绑定)成一个逻辑上的网卡，能够提升网络吞吐量、实现网络冗余、负载等功能，有很多优势。 Bonding 技术是 Linux 系统内核层面实现的，它是一个内核模块(驱动)。使用它需要系统有这个模块，我们可以modinfo命令查看下这个模块的信息，一般来说都支持。
1.4.2工作模式
Bonding提供了7种工作模式，在使用的时候需要指定一种，每种有各自的优缺点。在这里仅粗略介绍3种工作模式：
mode=0 balance-rr 默认。有高可用（容错）和负载均衡的功能，需要交换机的配置，每块网卡轮询发包（流量分发比较均衡）
mode=1 active-backup 只有高可用功能，不需要交换机配置，这种模式只有一块网卡工作，对外只有一个MAC地址。缺点是端利用口率比较低
mode=6 balance-alb 有高可用 ( 容错 ) 和负载均衡的功能，不需要交换机配置 ( 流量分发到每个接口不是特别均衡 )
1.4.3绑定步骤
关闭虚拟机，添加一块物理网卡设备，重启虚拟机。
1.4.4.1加载Bonding模块
[root@vastdata3 Desktop]# modprobe --first-time bonding
1.4.4.2查看模块是否被加载
[root@vastdata3 Desktop]# lsmod | grep bonding
1.4.4.3创建基于bond0接口的配置文件
[root@vastdata4 named]# cat /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 TYPE=Bond IPADDR=192.168.0.12 NETMASK=255.255.255.0 USERCTL=no BOOTPROTO=none ONBOOT=yes BONDING_MASTER=yes BONDING_OPTS="mode=0 miimon=100" ---工作模式、监视网络链接的频度（毫秒）
1.4.4.4修改eth0接口的配置文件
[root@vastdata4 named]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 USERCTL=no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none
1.4.4.5修改eth1接口的配置文件
[root@vastdata4 named]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 USERCTL=no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none
1.4.4.6追加dist.conf配置文件
[root@vastdata4 named]# vim /etc/modprobe.d/dist.conf alias bond0 bonding options bonding miimon=100 mode=0
1.4.4.7测试
重启网络服务
[root@vastdata3 Desktop]# service network restart
查看bond0接口的状态信息
[root@vastdata4 named]# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009) Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 08:00:27:ef:f6:15 Slave queue ID: 0 Slave Interface: eth1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 1 Permanent HW addr: 08:00:27:82:3a:57 Slave queue ID: 0
1.4.4.8查看网卡信息
[root@vastdata4 named]# ifconfig bond0 Link encap:Ethernet HWaddr 08:00:27:EF:F6:15 inet addr:192.168.0.12 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:feef:f615/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:348 errors:0 dropped:0 overruns:0 frame:0 TX packets:376 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:32868 (32.0 KiB) TX bytes:25441 (24.8 KiB) eth0 Link encap:Ethernet HWaddr 08:00:27:EF:F6:15 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:321 errors:0 dropped:0 overruns:0 frame:0 TX packets:188 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:31248 (30.5 KiB) TX bytes:12386 (12.0 KiB) eth1 Link encap:Ethernet HWaddr 08:00:27:EF:F6:15 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:27 errors:0 dropped:0 overruns:0 frame:0 TX packets:188 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1620 (1.5 KiB) TX bytes:13055 (12.7 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:177 errors:0 dropped:0 overruns:0 frame:0 TX packets:177 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:16325 (15.9 KiB) TX bytes:16325 (15.9 KiB)
1.5添加private私网物理网卡设备
添加两块物理网卡设备，桥接网络，10.0.0.0网段，修改配置文件，重启网络服务。
1.6配置DNS
1.6.1配置主域名解析服务器
1.6.1.1通过yum安装
[root@vastdata3 Desktop]# yum install bind bind-chroot -y
1.6.1.2修改DNS主配置文件
[root@vastdata3 Desktop]# cd /etc/ [root@vastdata3 etc]# vim named.conf [root@vastdata3 etc]# cp -p named.conf named.conf.bak [root@vastdata3 Desktop]# cat /etc/named.conf // // named.conf // // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS // server as a caching only nameserver (as a localhost DNS resolver only). // // See /usr/share/doc/bind*/sample/ for example named configuration files. // options { listen-on port 53 { any; }; directory "/var/named"; allow-query { any; }; allow-query-cache { any; }; recursion no; }; zone "." IN { type hint; file "named.ca"; }; zone "us.oracle.com" IN { type master; file "us.oracle.com.zone"; } zone "0.168.192.in-addr.arpa" IN { type master; file "192.168.0.local"; };
1.6.1.3配置正向域名解析文件
[root@vastdata3 Desktop]# cd /var/named/ [root@vastdata3 named]# cp -p named.localhost us.oracle.com.zone [root@vastdata3 named]# cp -p us.oracle.com.zone 192.0.2.local [root@vastdata3 Desktop]# cat /var/named/us.oracle.com.zone $TTL 1D @ IN SOA vastdata3.us.oracle.com. root.us.oracle.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS dns.us.oracle.com. vastdata3 A 192.168.0.11 vastdata4 A 192.168.0.12 vastdata-scan A 192.168.0.33 vastdata-scan A 192.168.0.34 vastdata-scan A 192.168.0.35 dns A 192.168.0.44 vastdata3-vip A 192.168.0.22 vastdata4-vip A 192.168.0.23 vastdata3-priv1 A 10.0.0.2 vastdata3-priv2 A 10.0.0.3 vastdata4-priv1 A 10.0.0.4 vastdata4-priv2 A 10.0.0.5
1.6.1.4配置反向域名解析文件
[root@vastdata3 Desktop]# cat /var/named/192.168.0.local $TTL 1D @ IN SOA vastdata3.us.oracle.com. root.us.oracle.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum IN NS dns.us.oracle.com. 11 IN PTR vastdata3.us.oracle.com. 12 IN PTR vastdata4.us.oracle.com. 33 IN PTR vastdata-scan.us.oracle.com. 34 IN PTR vastdata-scan.us.oracle.com. 35 IN PTR vastdata-scan.us.oracle.com. 44 IN PTR dns 22 IN PTR vastdata-vip.us.oracle.com. 23 IN PTR vastdata-vip.us.oracle.com.
1.6.1.5重启网络服务
[root@vastdata3 Desktop]# service network restart
1.6.1.6重启named服务并设置为开机启动
[root@vastdata3 Desktop]# service named restart [root@vastdata3 Desktop]# chkconfig named on [root@vastdata3 Desktop]# chkconfig named --list
1.6.1.7解析测试
[root@vastdata3 Desktop]# nslookup vastdata-scan.us.oracle.com Server: 192.168.0.12 Address: 192.168.0.12#53 Name: vastdata-scan.us.oracle.com Address: 192.168.0.34 Name: vastdata-scan.us.oracle.com Address: 192.168.0.35 Name: vastdata-scan.us.oracle.com Address: 192.168.0.33
1.6.2配置从域名解析服务器
它作为主域名解析服务器的辅助和备份服务器，自身不建立区域文件，而是从主域名解析服务器中查询并保存域名信息。
它可以与主域名解析服务器提供相同的解析服务，须在不同于主域名解析服务器的主机中构建。
1.6.2.1修改从域名解析服务器的主配置文件
[root@vastdata4 ~]# cd /etc/ [root@vastdata4 etc]# cat named.conf // // named.conf // // Provided by Red Hat bind package to configure the ISC BIND named(8) DNS // server as a caching only nameserver (as a localhost DNS resolver only). // // See /usr/share/doc/bind*/sample/ for example named configuration files. // options { directory "/var/named"; allow-query { any; }; recursion no; }; zone "us.oracle.com" IN { type slave; file "slave/us.oracle.com.zone"; masters { 192.168.0.11; }; allow-transfer { none; }; }; zone "0.168.192.in-addr.arpa" IN { type slave; file "slave/192.168.0.rev"; masters { 192.168.0.11; }; };
type设置为"slave"，代表当前DNS服务器是该域的从域名服务器类型，区域文件应从主域名解析服务器中获取，并保存在"slaves"子目录中，为便于管理，尽量使用与主服务器相同的区域文件名。使用master设置主域名解析服务器的IP地址。
1.6.2.2修改 resolv.conf配置文件
[root@vastdata4 ~]# cat /etc/resolv.conf # Generated by NetworkManager search us.oracle.com # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com nameserver 192.168.0.11
1.6.2.3启动named服务
[root@vastdata3 Desktop]# service named start
1.6.2.4解析测试
[root@vastdata4 ~]# service named restart Stopping named: [ OK ] Starting named: [ OK ] [root@vastdata4 ~]# nslookup vastdata-scan.us.oracle.com Server: 192.168.0.11 Address: 192.168.0.11#53 Name: vastdata-scan.us.oracle.com Address: 192.168.0.33 Name: vastdata-scan.us.oracle.com Address: 192.168.0.34 Name: vastdata-scan.us.oracle.com Address: 192.168.0.35
