一.前期环境准备
1.网络及主机名规划
2.安装软件包
使用YUM安装
# yum install -y binutils-* compat-libstdc++-* elfutils-libelf-*elfutils-libelf-devel-* gcc-* gcc-c++-* glibc-* glibc-common-* glibc-devel-*glibc-headers-* ksh-* libaio-* libaio-devel-*libgcc-* libstdc++-*make-*sysstat-* expat-* pdksh-* unixODBC-* libXp*
3. 建立用户和组
/usr/sbin/groupadd -g 501 oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 504 asmadmin
/usr/sbin/groupadd -g 506 asmdba
/usr/sbin/groupadd -g 507 asmoper
/usr/sbin/useradd -u 501 -g oinstall -G asmadmin,asmdba,asmoper,dba grid
/usr/sbin/useradd -u 502 -g oinstall -G dba,asmdba oracle
4. 创建grid目录结构
mkdir -p /u01/app/oraInventory
chown -R grid:oinstall /u01/app/oraInventory
chmod -R 775 /u01/app/oraInventory
mkdir -p /u01/app/grid
chmod -R 775 /u01/app/grid
chown -R grid:oinstall /u01/app/grid
mkdir -p /u01/app/11.2.0/grid
chown -R grid:oinstall /u01/app/11.2.0/grid
chmod -R 775 /u01/app/11.2.0/grid
mkdir -p /u01/software
chown -R grid:oinstall /u01/software/
chmod -R 775 /u01/software/
5.创建oracle目录结构
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/cfgtoollogs
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1
chmod -R 775 /u01/app/oracle/product/11.2.0/db_1
mkdir –p /u01/software
chmod -R 775 /u01
6. 配置内核参数
vi /etc/sysctl.conf
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6553600
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
生效：sysctl -p
7. 修改limits文件
vi /etc/security/limits.conf
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
8. 配置hangcheck-timer(11gr2+不用配置)
modprobe hangcheck-timer hangcheck_tick=1 hangcheck_margin=10 hangcheck_reboot=1
9. 修改pam文件
#vi /etc/pam.d/login
添加一行
session required pam_limits.so
10.配置ssh互信
(oracle和grid两个用户)
su - oracle
方法一：
（1）ssh-keygen -t rsa
（2）cd .ssh/
（3）mv id_rsa.pub authorized_keys
（4）ls -l
（5）chmod 600 authorized_keys
（6）cd ..
（7）scp -r .ssh/ 192.168.54.2:/home/oracle
grid测试：
ssh lxdrac1 date && ssh lxdrac1priv date && ssh lxdrac2 date && ssh lxdrac2priv date
ssh racjtv1 date && ssh racjtv1pri date && ssh racjtv2 date && ssh racjtv2pri date
oracle测试：
方法二：
$GI_OUI/sshsetup/sshUserSetup.sh -user grid -hosts "lxdrac1 lxdrac2" -advanced -noPromptPassphrase
$OUI_HOME/sshsetup/sshUserSetup.sh -user oracle -hosts "lxdrac1 lxdrac2" -advanced -noPromptPassphrase
11.用户环境变量设置
grid用户
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_SID=+ASM2
oracle用户
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export ORACLE_SID=lxdrac1
12. 关闭不需要的服务
chkconfigautofs off
chkconfigacpid off
chkconfigsendmail off
chkconfigcups-config-daemon off
chkconfigcpus off
chkconfigxfs off
chkconfiglm_sensors off
chkconfiggpm off
chkconfigopenibd off
chkconfigpcmcia off
chkconfigcpuspeed off
chkconfignfslock off
chkconfigip6tables off
chkconfigrpcidmapd off
chkconfigapmd off
chkconfigsendmail off
chkconfigarptables_jf off
chkconifgmicrocode_ctl off
chkconfigrpcgssd off
chkconfig ntpd off
/sbin/service ntpd stop
mv /etc/ntp.conf /etc/ntp.conf.bak （这时候oracle会自动启用自己的NTP服务）
13.共享存储规划
Vote_OCR |
/dev/sdb1 |
/dev/raw/raw1 |
2g |
Vote_OCR |
/dev/sdb2 |
/dev/raw/raw2 |
2g |
Vote_OCR |
/ dev/sdb3 |
/dev/raw/raw3 |
2g |

dev/sdb5 |
/dev/raw/raw4 |
5g |
DATA |
dev/sdb6 |
/dev/raw/raw5 |
5g |
DATA |
dev/sdb7 |
/dev/raw/raw6 |
5g |
做完分区之后 在两个节点上分别执行以下命令：
# partprobe
配置raw设备（每个节点都操作）
#vi /etc/udev/rules.d/60-raw.rules
ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdb3", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sdb5", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="sdb6", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="sdb7", RUN+="/bin/raw /dev/raw/raw6 %N"
KERNEL=="raw*", OWNER="grid" GROUP="asmadmin", MODE="0660"
# start_udev
启动 udev：
[确定]
二.安装GI
三.安装数据库软件
四.配置ASM DATADG
五.建库
