2、置：修改你的虚拟机配置文件（vmware configure file）.在这个文件的最后边加上三个参数disk.locking = FALSEscsi1.sharedBus = virtualscsi1:0.mode = persistentdiskLib.dataCacheMaxSize = 0diskLib.dataCacheMaxReadAheadSize = 0diskLib.DataCacheMinReadAheadSize = 0diskLib.dataCachePageSize = 4096diskLib.maxUnsyncedWrites = 0三、DNS 配置Oracle1
3、1gr2 RAC 是使用Single Client Access Name(SCAN),所以要DNS服务器来对SCANIP进行解析。以上是对DNS服务器的相关配置。这里是把DNS服务器放在节点一中来进行解析。1. DNS服务器所需要的RPM包：bind-9.3.6-4.P1.el5_4.2bind-libs-9.3.6-4.P1.el5_4.2bind-chroot-9.3.6-4.P1.el5_4.2bind-utils-9.3.6-4.P1.el5_4.2bind-devel-9.3.6-4.P1.el5_4.2bind-sdb-9.3.6-4.P1.el5_4.2caching-name
4、server-9.3.6-4.P1.el5_4.22. 对DNS主配置文件由于REDHAT5.0是用chroot来对DNS服务器的配置。所以直接去/var/named/chroot/etc/named.conf在named.conf 添加以下内容options listen-on port 53 192.168.2.111; directory /var/named; dump-file /var/named/cache_dump.db; statistics-file /var/named/data/named_stats.txt; memstatistics-file /var/named
5、/data/named_mem_stats.txt; allow-query 192.168.2.0/24; ;include /etc/rndc.key;zone type master; file /var/named/.hosts; ;zone 2.168.192.in-addr.arpa type master; file /var/named/192.168.2.rev; ;zone 1.1.10.in-addr.arpa type master; file /var/named/10.1.1.rev; ;3. 编辑正向，反向解析配置文件DNS服务器需要对服务器的名字进行正向，反向
6、的解释。Named 的默认目录是/var/named/chroot里面.以下是正向解释Cd /var/named/chroot/var/namedVi .hosts$ttl 86400 IN SOA . .( 1282236195 10800 3600 604800 38400 ) IN NS . IN A . IN A 192.168.2.112testdb-. IN A 192.168.2.115testdb1-. IN A 10.1.1.121testdb2-. IN A 10.1.1.122testdb1-. IN A 192.168.2.113testdb2-. IN A 192.1
7、68.2.114testdb-. IN A 192.168.2.116testdb-. IN A 192.168.2.117还要反向对public,以及private进行解释Public的反向解释：Vi 192.168.2.rev$ttl 86400 IN SOA . . ( 1282236195 10800 3600 604800 38400 ) IN NS .111.2.168.192.in-addr.arpa. IN PTR .112.2.168.192.in-addr.arpa. IN PTR .113.2.168.192.in-addr.arpa. IN PTR testdb1-.1
8、14.2.168.192.in-addr.arpa. IN PTR testdb2-.115.2.168.192.in-addr.arpa. IN PTR testdb-.116.2.168.192.in-addr.arpa. IN PTR testdb-.117.2.168.192.in-addr.arpa. IN PTR testdb-.Private 的反向解释：Vi 10.1.1.rev$ttl 86400 IN SOA . ( 1282248634 10800 3600 604800 38400) IN NS .121.1.1.10.in-addr.arpa IN PTR testd
9、b1-.122.1.1.10.in-addr.arpa IN PTR testdb2-.然后启动DNS服务：Service named restart配置连接的DNS连接Vi /etc/resolv.confsearch nameserver 192.168.2.1114. 对DNS进行正向，反向验证正向验证roottestdb1 named# nslookup testdb-Server: 192.168.2.111Address: 192.168.2.111#53Name: testdb-Address: 192.168.2.117Name: testdb-Address: 192.168
10、.2.115Name: testdb-Address: 192.168.2.116反向验证roottestdb1 named# host 192.168.2.115115.2.168.192.in-addr.arpa domain name pointer testdb-.三、主机名设置：分别在两台节点做以下设定计算机名Hostname rac1 (一机)Hostname rac2 （二机）Vi /etc/hosts127.0.0.1localhost.localdomain localhost:1localhost6.localdomain6 localhost6192.168.2.100
