Oracle11g+asm+RAC安装指导
环境说明：
网络接口、IP分配： # public bind0
192.100.65.19 tpps-ora01 192.100.65.20 tpps-ora02 # vip
192.100.65.21 tpps-ora01-vip 192.100.65.22 tpps-ora02-vip
# private
172.16.65.19 tpps-ora01-priv 172.16.65.20 tpps-ora02-priv
# scan
192.100.65.23 orascan
主机名：
修改hostname如主节点tpps-ora01,次节点tpps-ora02
注：图里的rac01改为tpps-ora01,rac02改为tpps-ora02下面所有图都是如此操作。 [root@localhost ~]#vi/etc/sysconfig/network
关闭SELINUX配置：
[root@localhost ~]#cat /etc/selinux/config
# This file controls the state of SELinux on the system. # SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing. # 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. SELINUXTYPE=targeted 关闭防火墙：
[root@localhost ~]#chkconfig --list iptables
iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off [root@localhost ~]#chkconfigiptables off [root@localhost ~]# chkconfig --list iptables
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
1.检查每个节点的OS环境
1检查可用空间： ○
[root@localhost ~]# df -h
FilesystemSize Used Avail Use% Mounted on
/dev/sda2 124G 4.2G 114G 4% /
/dev/sda1 494M 17M 452M 4% /boot tmpfs 2.0G 0 2.0G 0% /dev/shm 2网络配置： ○
登录系统，修改/etc/sysconfig/network-scripts路径下文件 将对应网卡地址改为相应的IP。
3时间同步协议NTP配置：（不建议使用NTP） ○
备份ntp.conf文件
[root@tpps-ora01 ~]#cp /etc/ntp.conf /etc/ntp.conf.bak [root@tpps-ora02 ~]# cp /etc/ntp.conf /etc/ntp.conf.bak [root@tpps-ora02 ~]# vi /etc/ntp.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html). #server 0.rhel.pool.ntp.org #server 1.rhel.pool.ntp.org #server 2.rhel.pool.ntp.org
server 10.10.11.26
[root@tpps-ora01 ~]#chkconfigntpd on [root@tpps-ora02 ~]#chkconfigntpd on [root@tpps-ora01 ~]#servicentpd start [root@tpps-ora02 ~]# servicentpd start ntpq–p
4NSLOOKUP域名解析：（无域名解析） ○
节点1
[root@tpps-ora01 ~]# mv /usr/bin/nslookup /usr/bin/nslookup.bak [root@tpps-ora01 ~]# vi /usr/bin/nslookup
#!/bin/bash
HOSTNAME=${1}
if [[ $HOSTNAME=\echo \ 192.100.65.21\echo \ 192.100.65.21#53\echo \echo \ orascan\echo \ 192.100.65.23\else
/usr/bin/nslookup.bak $HOSTNAME fi
[root@tpps-ora01 ~]# chmod 755 /usr/bin/nslookup [root@tpps-ora01 ~]# nslookuporascan
节点2
[root@tpps-ora02 ~]#mv /usr/bin/nslookup /usr/bin/nslookup.bak [root@tpps-ora02 ~]#vi /usr/bin/nslookup
#!/bin/bash
HOSTNAME=${1}
if [[ $HOSTNAME=\echo \ 192.100.65.22\echo \ 192.100.65.22#53\echo \echo \ orascan\echo \ 192.100.65.22\else
/usr/bin/nslookup.bak $HOSTNAME fi
[root@tpps-ora02 ~]# chmod 755 /usr/bin/nslookup [root@tpps-ora02 ~]# nslookuporascan 5OS调整 ○
