环境：centos7.9? ? ? ? Oracle11.2.0.4
###准备工作###
1、云服务器两台
IP：10.10.161.60，10.10.161.68
2、共享磁盘五块找基础设施组申请。
磁盘规划：
100G数据盘，50G归档盘，3个10G的OCR盘
/dev/sdb ocr
/dev/sdc ocr
/dec/sdd ocr
/dev/sde arch
/dev/sdf data
3、网卡两块找基础设施组申请。
4、心跳IP两个、VIP两个、scan-ip一个找网络组预留。
预留心跳ip：
172.16.10.21
172.16.10.22
vip:
10.10.161.160
10.10.161.168
预留scan ip:
10.10.161.200
准备工作完成后，下面开始操作
二、磁盘分区
这里我们简介一些，我相信安装O
racle软件的都会磁盘分区
fdisk /dev/sdb
n
p
回车

三、上传软件包到服务器
?四、节点安装集群相关安装包（两个节点执行）
#注意：要配好yum源
#检查软件依赖环境
yum install binutils elfutils-libelf-devel zlib-devel ?sysstat ??make libXtstlibXi libstdc++-devel libstdc++- libgcc ?libaio-devellibaio? ksh glibc-devel glibc ??gcc-c++ ?compat-libstdc++-33 compat-libcap1 ?gcc? -y
#覆盖一次
yum -y install binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel
#安装完成后，检查依赖是否安装成功
rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel | grep "not installed"五、设置主机名并关闭防火墙、selinux（两个节点执行）
#节点1
hostnamectl set-hostname rac1
bash
systemctl stop firewalld
systemctl disable firewalld?
setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
#节点2
hostnamectl set-hostname rac2
bash
systemctl stop firewalld
systemctl disable firewalld?
setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config
六、创建用户（两个节点执行）
groupadd -g 502 dba
groupadd -g 503 oper
groupadd -g 504 asmadmin
groupadd -g 505 asmoper
groupadd -g 506 asmdba
groupadd -g 507 oinstall
useradd -g oinstall -G dba,asmdba,oper oracle
useradd -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid
#修改用户密码(自己要能记住)
passwd oracle
passwd grid七、创建目录（两个节点执行）
mkdir -p /u01/app/grid
mkdir -p /u01/app/11.2.0/grid
chown -R grid:oinstall /u01
mkdir -p /u01/app/oraInventory
chown -R grid:oinstall /u01/app/oraInventory
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01八、设置系统参数（两个节点执行）
[root@rac1 /]# vi /etc/security/limits.d/20-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
#* soft nproc4096
rootsoft nproc unlimited
*- nproc 16384
[root@rac1 /]# vi /etc/security/limits.conf
#ORACLE SETTING
grid soft nproc2047
grid hard nproc16384
grid soft nofile1024
grid hard nofile65536
grid soft stack10240
grid hard stack32768
oracle soft nproc2047
oracle hard nproc16384
oracle soft nofile1024
oracle hard nofile65536
oracle soft stack10240
oracle hard stack32768
使用centos 7.2 安装grid时，需要修改这个参数，不然asm组件会起不来，crs时好时不好
[root@rac1 /]# vi /etc/systemd/logind.conf

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 <ENTER> without 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

[grid@rac1:/home/grid]$ cd /u01/app/soft/grid
[grid@rac1:/home/grid]$ ./runInstall三、grid图形化安装

#安装完成?来解决这个参数的问题，后面有yes的直接店第二个选项用root执行下面这个脚本，然后再检查（两个节点）
#开始安装
#根据弹窗提示，执行弹窗中的脚本
要求：以root用户登录，首先在第1个节点上执行成功后，再到其他节点上执行。?
?
?执行此脚本时会报错
CRS-2101:The OLR was formatted using version 3.
需要执行命令在开个窗口执行---/etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null &
会继续执行，后面出现successfully。
?说明：
安装过程中，创建了OCR、vote disk。
OCR:集群的配置信息
Vote disk:表决磁盘
10g:无表决磁盘
11g:DATA磁盘组
#节点1执行完，开始执行节点2
可能还会报别的错，因为11g适合在centos6用，centos7一般适用于12c的库了，继续往下走
?报错?[client(345280)]CRS-2101:The OLR was formatted using version 3.
执行完完继续往下走---/etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null &
?又说执行失败，Disk Group OCR creation failed with the following message，创建OCR失败，去用命令扫一下磁盘
?find / -name *OCR* 去找下磁盘路径
--------------------------------------------------------------------------------
?这就神奇了，能扫出来磁盘，但是脚本报错找不到磁盘，如果这步扫不出来，但是磁盘确认已经创了，那就chown 一下磁盘组的所属主和组，先改成root，在改回来grid:asmadmin，
[grid@rac2:/home/grid]$?kfod disks=all status=ture ?asm_diskstring='/dev/oracleasm/disks/*'??
?如果还不行，重启下服务器，要先启集群，在开始执行root.sh，不然会报集群css挂了和检查集群状态，/etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null &，然后重新执行root.sh脚本
?重启完，观察日志的流动less /u01/app/11.2.0/grid/cfgtoollogs/crsconfig/rootcrs_rac2.log ,显示节点2已经注册好了
?#点OK，下一步，提示报错[INS-20802]，点击跳过忽略（不影响）
?
?输入命令查看grid安装情况：
crs_stat -t
?
查看asm进程
ps -ef|grep ASM
?
?###安装数据库软件###
一、拷贝Oracle软件，并使用root权限授权777，然后用oracle用户解压。
chmod +777 p13390677_112040_Linux-x86-64_*
?二、登录oracle用户，设置变量DISPLAY
[oracle@rac1:/home/oracle]$export DISPLAY=10.10.161.60:1.0
[root@rac1 ~]# xhost +
access control disabled, clients can connect from any host三、解压两个p13390677_112040_Linux-x86-64.zip
四、到目录执行脚本

（对等性安装完成后即可测试ssh在节点1和2之间互相连接测试）
?
?#选择语言

?#默认安装企业版
?#默认Oracle的base目录和Oracle的home目录
?#修改数据库组（OSOPER）为oinstall,默认SODBA为dba
?#因为没有DNS，提示Task和SCAN报错，2个错误均可忽略，然后下一步。
?#开始安装
?#Error in invoking target ‘agent nmhs‘ of makefile 报错，应该是86%报错，我是56%报错，但是报错信息一致
解决方案：
在makefile中添加链接libnnz11库的参数
修改$ORACLE_HOME/sysman/lib/ins_emagent.mk，将
$(MK_EMAGENT_NMECTL)修改为：$(MK_EMAGENT_NMECTL) -lnnz11
建议修改前备份原始文件
[oracle@ysserver ~]$?cd $ORACLE_HOME/sysman/lib
[oracle@ysserver lib]$?cp ins_emagent.mk ins_emagent.mk.bak
[oracle@ysserver lib]$?vi ins_emagent.mk末行模式查找 /NMECTL 后面添加? ? -lnnz11
#然后重试?
#需要root用户执行脚本，然后ok
?#完成后查看监听状态（两个节点oracle和grid都要查看）
??###ASMCA建磁盘组###
?一、创建磁盘组
#因为刚装完grid，可以直接调用图形化
asmca#可以看到，ASM中已经存在了一个OCR磁盘组，现在要给数据库创建DATA磁盘组，选择【Disk Groups】选项卡，点击左下角【Create】
?二、asmca调用图形化创建的时候出现了一个问题，桌面显示不齐
