1.2、创建账户
分别在两台服务器上创建如下账户。
groupadd-g 1000 oinstall
groupadd -g 1200asmadmin
groupadd -g 1201asmdba
groupadd -g 1202asmoper
useradd -m -u 1100 -goinstall -G asmadmin,asmdba,asmoper -d /home/grid -s /bin/bash grid
groupadd -g 1300 dba
groupadd -g 1301oper
useradd -m -u 1101 -goinstall -G dba,oper,asmdba -d /home/oracle -s /bin/bash oracle
mkdir -p /u01/app/grid
mkdir -p /u01/app/11.2.0/grid
chown -R grid:oinstall/u01
mkdir -p /u01/app/oracle
chown -R oracle:oinstall/u01/app/oracle
chmod -R 775 /u01
passwd oracle
1.3、配置hosts文件
配置两台服务器hosts文件。
#vi /etc/hosts
10.18.199.209 jason1
10.0.0.1 jason1-priv
10.18.199.221 jason1-vip
10.18.199.210 jason2
10.0.0.2 jason2-priv
10.18.199.222 jason2-vip
10.18.199.223 jason-cluster jason-cluster-scan
1.4、安装所需rpm包
两节点均查看所需rpm包，安装所需rpm包。
#rpm -q binutils gcc gcc-32bit gcc-c++ glibc glibc-32bitglibc-devel glibc-devel-32bit ksh libaio libaio-32bit libaio-devellibaio-devel-32bit libstdc++33 libstdc++33-32bit libstdc++43 libstdc++43-32bitlibstdc++43-devel libstdc++43-devel-32bit libgcc43 libstdc++-devel make sysstatunixODBC unixODBC-devel unixODBC-32bit unixODBC-devel-32bit libcap1

1.5、修改内核参数
设置两台服务器的内核参数
#vi /etc/sysctl.conf
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
fs.inotify.max_user_watches = 65536
net.ipv4.conf.default.promote_secondaries = 1
net.ipv4.conf.all.promote_secondaries = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 978288640
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
vm.hugetlb_shm_group= 1000 ###此处为oinstall group number
1.6、设置Shell对Oracle与grid用户的限制
#vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
编辑/etc/pam.d/login，添加如下内容：
vi /etc/pam.d/login
session required pam_limits.so
1.7、禁用NTP服务
在两台服务器上均禁止NTP服务
service ntp stop
chkconfig ntp off
mv /etc/ntp.conf /etc/ntp.conf.bak

}
添加/etc/udev/rules.d/99-oracle-asmdevices.rules文件，修改设备文件权限。
使用如下命令查询
for i in 1 2 3
do
echo "KERNEL==\"dm-*\", SUBSYSTEM==\"block\",PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\",RESULT==\"` /sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/dm-$i`\", OWNER=\"grid\",GROUP=\"asmadmin\", MODE=\"0660\""
done
