ulimit -u 16384 -n 65536 fi umask 022 fi
(6)执行命令(rac1、rac2) source /etc/profile
(7)修改rac1和rac2的/etc/csh.login vi /etc/csh.login
if ( $USER = \
limit maxproc 16384 limit descriptors 65536 endif EOFCSH
(8)修改grid用户的环境变量 rac1
su - grid
vi .bash_profile
export ORACLE_SID=+ASM1
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid/product/db_1 export PATH=$PATH:$ORACLE_HOME/bin rac2
su - grid
vi .bash_profile

su - oracle
vi .bash_profile
export ORACLE_SID=PROD2
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export PATH=$PATH:$ORACLE_HOME/bin (11)执行命令(rac1、rac2) source .bash_profile
7.配置SSH互信
(1)使用oracle用户，在所有节点执行 su –oracle mkdir ~/.ssh cd .ssh
ssh-keygen -t rsa ssh-keygen -t dsa 在rac1上：
touch authorized_keys
ssh rac1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys ssh rac2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys ssh rac1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys ssh rac2 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys ssh rac1-priv cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys ssh rac2-priv cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys ssh rac1-priv cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys ssh rac2-priv cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys scp authorized_keys rac2:/home/oracle/.ssh/ 分别在rac1，rac2测试ssh互信 rac1
ssh ssh rac1 date ssh rac2 date
ssh rac1-priv date ssh rac2-priv date rac2
ssh rac1 date ssh rac2 date
ssh rac1-priv date ssh rac2-priv date
(2)使用grid用户，在所有节点执行 su –grid mkdir ~/.ssh cd .ssh
ssh-keygen -t rsa ssh-keygen -t dsa 在rac1上：
touch authorized_keys
ssh rac1 cat /home/grid/.ssh/id_rsa.pub >> authorized_keys ssh rac2 cat /home/grid/.ssh/id_rsa.pub >> authorized_keys ssh rac1 cat /home/grid/.ssh/id_dsa.pub >> authorized_keys ssh rac2 cat /home/grid/.ssh/id_dsa.pub >> authorized_keys ssh rac1-priv cat /home/grid/.ssh/id_rsa.pub >> authorized_keys ssh rac2-priv cat /home/grid/.ssh/id_rsa.pub >> authorized_keys ssh rac1-priv cat /home/grid/.ssh/id_dsa.pub >> authorized_keys ssh rac2-priv cat /home/grid/.ssh/id_dsa.pub >> authorized_keys scp authorized_keys rac2:/home/grid/.ssh/ 分别在rac1，rac2测试ssh互信 rac1
ssh ssh rac1 date
ssh rac2 date
ssh rac1-priv date ssh rac2-priv date rac2
ssh rac1 date ssh rac2 date
ssh rac1-priv date ssh rac2-priv date
8.安装ASM
(1)检查系统及内核版本 uname -a
(2)下载与系统及内核版本对应的ASM,并安装 下载地址：
http://www.oracle.com/technetwork/server-storage/linux/downloads/index.html 例如：
rpm -ivh --nodeps oracleasmlib-2.0.4-1.el5.x86_64.rpm
rpm -ivh --nodeps oracleasm-support-2.1.8-1.el5.x86_64.rpm
rpm -ivh --nodeps oracleasm-2.6.18-164.el5-2.0.5-1.el5.x86_64.rpm rpm -ivh --nodeps oracleasm-2.6.18-164.el5-debuginfo-2.0.5-1.el5.x86_64.rpm
rpm -ivh --nodeps oracleasm-2.6.18-164.el5debug-2.0.5-1.el5.x86_64.rpm rpm -ivh --nodeps oracleasm-2.6.18-164.el5xen-2.0.5-1.el5.x86_64.rpm 如果操作系统为oracle版本的linux，直接使用yum安装即可 yum install -y oracleasm*
(3)初始化asmlib，在所有节点执行 oracleasm configure -i
[root@rac01 ~]# 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 ('[]'). Hitting
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) [n]: y Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done (4)ASMlib加载到内核，在所有节点执行
