安装Oracle 11g R2 RAC-Linux一万小时
一、准备单实例数据库服务器1、准备操作系统
注：建议安装oracle数据库使用oracle linux操作系统，本实例以oracle linux 6.8做为操作系统。
#关闭iptables
chkconfig iptables off
#关闭selinux
vim /etc/sysconfig/selinux
SELINUX=disabled
#将主机名添加到hosts文件
vim /etc/hosts
188.188.1.141 scan-cluster.localdomain scan-cluster
188.188.1.142 oraclerac01.localdomain oraclerac01
188.188.1.144 oraclerac01-vip.localdomain oraclerac01-vip
10.10.1.142 oraclerac01-priv.localdomain oraclerac01-priv
188.188.1.143 oraclerac02.localdomain oraclerac02
188.188.1.145 oraclerac02-vip.localdomain oraclerac02-vip
10.10.1.143 oraclerac02-priv.localdomain oraclerac02-priv
#重启服务器
reboot
2、初始化操作系统，执行以下脚本
#用户初始化脚本preusers.sh
注：节点2需要更改ORACLE_SID、ORACLE_HOSTNAME

3、配置ASM磁盘组
注：由于oracle rac使用了asm存储数据文件，单实例数据库也使用asm存储数据库文件，磁盘组需要与RAC磁盘组一致，方便还原
#磁盘分区
fdisk /dev/sd*
n-p-1-w
#安装asm
yum install -y kmod-oracleasm-2.0.8-13.el6_8.x86_64.rpm oracleasmlib-2.0.4-1.el6.x86_64.rpm oracleasm-support-2.1.8-1.el6.x86_64.rpm
#创建asm磁盘
----------------------------------------------------------------------------------------------------------------------------
# oracleasm status
# oracleasm configure -i
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver.The following questions will determine whether the driver is
loaded on boot and what permissions it will have.The current values
will be shown in brackets ('[]').Hittingwithout typing an
answer will keep that current value.Ctrl-C will abort.
Default user to own the driver interface []: grid
Default group to own the driver interface []: asmadmin
Start Oracle ASM library driver on boot (y/n) : y
Scan for Oracle ASM disks on boot (y/n) : y
Writing Oracle ASM library driver configuration: done
# oracleasm init
# oracleasm configure
# oracleasm listdisks
# oracleasm createdisk VOL1 /dev/sdb1
# oracleasm querydisk /dev/sd*
----------------------------------------------------------------------------------------------------------------------------
#另一节点挂载asm磁盘
# oracleasm scandisks
# oracleasm listdisks
4、安装必备rpm
yum install -y binutils elfutils-libelf glibc compat-libstdc++-33.x86_64 libgcc unixODBCglibc.i686 elfutils-libelf-devel gcc-c++ libaio-devel libstdc++-devel unixODBC-devel pdksh xorg-x11-* compat-libcap1 ksh-20100621
5、配置2节点oracle、grid互相ssh免密码登录
#配置oracle，grid用户类似配置
su - oracle
ssh-keygen -t rsa
ssh-keygen -t dsa
cat .ssh/id_dsa.pub >>authorized_keys
cat .ssh/id_rsa.pub >>authorized_keys
#另一节点的id_dsa.pub、id_rsa.pub的内容也添加到authorized_keys，并将authorized_keys传到另一节点
ssh oraclerac02
ssh oraclerac01-priv
ssh oraclerac01
ssh oraclerac01.localdomain
ssh oraclerac01-priv.localdomain
ssh oraclerac02
ssh oraclerac02-priv.localdomain
ssh oraclerac02.localdomain
ssh oraclerac02-priv
6、安装grid
注：新打开一个未登录xshell窗口，使用grid账户登录，如果直接从root切换到grid账户,则xshell无法打开安装grid图像化界面
ssh grid@188.188.1.120
cd grid/
#检查配置
./runcluvfy.sh stage -pre crsinst -n oraclerac01,oraclerac02 -fixup -verbose
./runInstaller
#创建和rac数据库一样的磁盘组
asmca
7、安装oracle，只需安装软件，不创建数据库
注：新打开一个未登录xshell窗口，使用oracle账户登录，如果直接从root切换到oracle账户,则xshell无法打开安装oracle图像化界面
ssh oracle@188.188.1.120
cd database/
./runInstaller
#创建数据库
dbca
