一、安装说明
1、环境说明

2、软件存放位置规划如下：

3、RAC数据库需要共享存储：
CRSDG：3块至少3GB以上的盘，用于存放ocr、voting disk，asm的spfile。
DATADG：至少200GB，用于存放redolog、控制文件、数据库的spfile、数据库的system表空间、undo表空间、temp表空间。根据实际业务需求，增加DATADG的容量。
ARCHDG：至少100GB，用户存放归档日志。根据实际业务需求，增加DATADG的容量。

sysstat-10.1.5-1.el7.x86_64

2、系统参数
可参考系统内核参数MOS Doc ID: 169706.1

vi /etc/sysctl.conf:
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 10485760
kernel.shmmax = 34359738368
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 = 1048586

3、设置oracle用户shell限制：

/etc/security/limits.conf
oracle  soft  nproc   2047
oracle  hard  nproc   16384
oracle  soft  nofile  1024
oracle  hard  nofile  65536
oracle  soft  stack   10240
oracle  hard  stack   32768

4、/etc/pam.d/login添加：

session required pam_limits.so
/etc/profile添加：
if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
       ulimit -u 16384
       ulimit -n 65536
    else
       ulimit -u 16384 -n 65536
    fi
fi

5、hosts

vi /etc/hosts
192.168.3.2  tim1
10.10.10.1  tim1-priv
192.168.3.88  tim1-vip
192.168.3.3  tim2
10.10.10.2  tim1-priv
192.168.3.99  tim2-vip
192.168.3.111  rac-scan

6、用户与组

groupadd -g 200 oinstall
groupadd -g 201 dba
groupadd -g 202 oper
groupadd -g 203 asmadmin
groupadd -g 204 asmoper
groupadd -g 205 asmdba

useradd -u 200 -g oinstall -G dba,asmdba,oper oracle
useradd -u 201 -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid

7、目录

mkdir -p /u01/app/oraInventory
chown -R grid:oinstall /u01/app
chmod -R 775 /u01/app/oraInventory/
mkdir -p /u01/11.2.0/grid
chown -R grid:oinstall /u01/11.2.0
chmod -R 775 /u01/11.2.0
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/cfgtoollogs
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle

8、环境变量
###注意以下环境变量参数为Node1，与Node2不同之处在于Oracle_sid。
grid用户

export EDITOR=vi
export ORACLE_SID=+ASM1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/11.2.0/grid
export GRID_HOME=/u01/11.2.0/grid
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export THREADS_FLAG=native
export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
umask 022

oracle用户

export EDITOR=vi
export ORACLE_SID=prod1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
umask 022

8、udev
###node1，node2都需要配置

[root@tim1 ~]#vi /etc/udev/rules.d/60-raw.rules     按照example编写如下：
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="33",RUN+="/bin/raw /dev/raw/raw1 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="34",RUN+="/bin/raw /dev/raw/raw2 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="35",RUN+="/bin/raw /dev/raw/raw3 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="36",RUN+="/bin/raw /dev/raw/raw4 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="37",RUN+="/bin/raw /dev/raw/raw5 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="38",RUN+="/bin/raw /dev/raw/raw6 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="39",RUN+="/bin/raw /dev/raw/raw7 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="40",RUN+="/bin/raw /dev/raw/raw8 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="41",RUN+="/bin/raw /dev/raw/raw9 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="42",RUN+="/bin/raw /dev/raw/raw10 %M %m"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="43",RUN+="/bin/raw /dev/raw/raw11 %M %m"
KERNEL=="raw[1-9]", OWNER="grid", GROUP="dba", MODE="660"
KERNEL=="raw10", OWNER="grid", GROUP="dba", MODE="660"
KERNEL=="raw11", OWNER="grid", GROUP="dba", MODE="660"
[root@node1 ~]# start_udev
[root@node2 ~]# ll /dev/raw/raw*
crw-rw---- 1 grid dba 162,  1 Apr 17 21:10 /dev/raw/raw1
crw-rw---- 1 grid dba 162, 10 Apr 17 21:10 /dev/raw/raw10

crw-rw---- 1 grid dba 162,  7 Apr 17 21:10 /dev/raw/raw7
crw-rw---- 1 grid dba 162,  8 Apr 17 21:10 /dev/raw/raw8
crw-rw---- 1 grid dba 162,  9 Apr 17 21:10 /dev/raw/raw9

9、启动图形化


10、安装grid




Grid只认出了Node1节点，Node2需要手动添加一下。













11、安装oracle




可将简体中文加上







这是在向node2复制数据，可以在node2的$ORACLE_HOME下，
通过du -sh 查看进度

至此安装结束！！可能有些刚了解oracle 的按此步骤会报错，因为我没有配置两个节点grid、oracle用户互信，其实可以在图形化中操作，努力找一找吧！！
12、检查

查看集群资源
        [grid@tim1 ~]$ crsctl status res -t
检查ASM状态
        [grid@tim1 ~]$ asmcmd -p
检查ocr状态
        [grid@tim1 ~]$ ocrcheck
检查voting disk状态
        [grid@tim1 ~]$ crsctl query css votedisk
检查节点信息
        [grid@tim1 ~]$ srvctl config nodeapps
检查数据库信息
        [grid@tim1 ~]$ srvctl config database -d prod
检查接口状态
        [grid@tim1 ~]$ oifcfg iflist -p -n

        [grid@tim1 ~]$ oifcfg getif -global
检查监听状态
        [grid@tim1 ~]$ lsnrctl status
