2.OS安装(具体过程略过)

swap规则: 内存<8G则物理内存2倍，>8G <16G 则等于物理内存，>16G物理内存一半

3.OS准备工作

(1).关闭防火墙

systemctl status firewalld  查看防火墙状态
systemctl stop firewalld  关闭防火墙
systemctl disable firewalld  禁用防火墙

(2).关闭selinux

getenforce 查看selinux的模式

修改/etc/selinux/config 文件，SELINUX=enforce –> disable

#setenforce 0  配置生效

(3).设置FTP

查看 getsebool -a |grep ftp

修改权限

setsebool ftpd_use_nfs on

setsebool ftp_home_dir on

setsebool ftpd_full_access on

setsebool ftpd_use_passive_mode on

允许root登录FTP

注释掉ftpusers和user_list 中的root行
重启服务systemctl restart vsftpd.service

(4).配置yum

删除rm /etc/yum.repos.d/packagekit-media.repo
建立 local.repo 文件
[test]
name=test
baseurl="file:///run/media/root/RHEL-7.0 Server.x86_64"
gpgcheck=0
enable=1

# yum clean all
# yum list

(5). 根据官方文档进行patch

useradd -u 61002 -g oinstall -G dba,backupdba,oper,dgdba,kmdba,asmdba,asmadmin oracle

(8).创建软件安装目录

mkdir -p /oracle/app/grid
mkdir -p /oracle/app/12.2.0.1/grid
chown -R grid:oinstall /oracle

mkdir -p /oracle/app/oraInventory
chown -R grid:oinstall /oracle/app/oraInventory

mkdir -p /oracle/app/oracle
chown -R oracle:oinstall /oracle/app/oracle
chmod -R 775 /oracle

注释*          soft    nproc     4096
添加*          -       nproc     16384

(11)./etc/pam.d/login

添加
#ORACLE SETTING
session    required     pam_limits.so

(12).修改内核参数
#vi /etc/sysctl.conf
#ORACLE SETTING
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 524288

net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 9000 65500
# sysctl –p 配置生效

参考官方文档

https://docs.oracle.com/database/122/LADBI/minimum-parameter-settings-for-installation.htm#LADBI-GUID-CDEB89D1-4D48-41D9-9AC2-6AD9B0E944E3

kernel	说明
SHMMAX	Linux进程可以分配的单独共享内存段的最大值。一般设置为内存总大小的一半。这个值的设置应该大于SGA_MAX_TARGET或MEMORY_MAX_TARGET的值
SHMMIN	最小的内存segment的大小
shmall	设置共享内存总页数SHMMAX/4K

(13).配置环境变量
grid
PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
umask 022
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
export ORACLE_HOSTNAME=rac1
export ORACLE_SID=+ASM1
export ORACLE_TERM=xterm
export ORACLE_BASE=/oracle/app/grid
export ORACLE_HOME=/oracle/app/12.2.0.1/grid
export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"
PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH
export THREADS_FLAG=native

oracle
PS1="[`whoami`@`hostname`:"'$PWD]$'
export PS1
umask 022
export TMP=/tmp
export LANG=en_US
export TMPDIR=$TMP
export ORACLE_HOSTNAME=rac1
export ORACLE_UNQNAME=racdb12c
export ORACLE_BASE=/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0.1/db_1
export ORACLE_SID=racdb12c1

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH
export THREADS_FLAG=native

(14).配置SSH

在主节点上以grid,oracle用户身份生成公钥和私钥
mkdir ~/.ssh
ssh-keygen -t rsa
ssh-keygen -t dsa

在另外的节点上执行相同的操作
在1节点使用oracle(grid)用户执行以下操作
cat ~/.ssh/id_rsa.pub >> ./.ssh/authorized_keys
cat ~/.ssh/id_dsa.pub >> ./.ssh/authorized_keys
ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys

在1,2节点上测试ssh
ssh rac1 date
ssh rac2 date
ssh rac1-priv date
ssh rac2-priv date

4.修改虚拟机配置文件(.vmx),添加以下内容
disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
disk.EnableUUID = "TRUE"
scsi1.sharedBus = "VIRTUAL"

5.配置共享存储

Name	Size
dggrid1	40GB
dggrid2	10GB
dgsystem	21GB
dgrecover	22GB
dgdata1	23GB
dgdata2	24GB

(1).编辑/etc/scsi_id.config，添加下面内容
options=--whitelisted --replace-whitespace

(2).获取需要绑定ASM Disk磁盘的uuid
for i in b c d e f g;
do
echo "sd$i" "`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`";
done

sdb 36000c29b0e11cfc09873aa3dc45baf3e
sdc 36000c293313041c3f662d837263cbef3

sdg 36000c29e8abe980615022c02a11960d1

(3).编写udev rules 文件
for i in b c d e f g;
do
echo "KERNEL==\"sd*\",BUS==\"scsi\",PROGRAM==\"/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\",RESULT==\"`/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\",NAME=\"asm-disk$i\",OWNER=\"grid\",GROUP=\"asmadmin\",MODE=\"0660\""
done

redhat 7

# vi /etc/udev/rules.d/99-oracle-asmdevices.rules
#/sbin/udevadm trigger --type=devices --action=change

(4).重启udev设备
/sbin/udevadm control –reload-rules
/sbin/start_udev  #redhat7 整合到systemctl restart systemd-udev-trigger.service 中
ll /dev/asm*

6.安装VNC
#yum install libvncserver.x86_64 –y
#yum install tigervnc.x86_64 –y
#yum install tigervnc-server.x86_64 –y

# vncserver 开启服务并设置密码

7.安装cvuqdisk包并验证(所有节点都装)
# cd /tmp/wwj/GI/cv/rpm
# export CVUQDISK_GRP=oinstall
# rpm -ivh cvuqdisk-1.0.10-1.rpm

./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup –verbose
./runcluvfy.sh stage –post hwos –n rac1,rac2 –verbose

8.安装GI

su – grid
cd $ORACLE_HOME
unzip -q download_location/grid.zip

执行安装脚本
gridSetup.sh

安装后检查

9.创建ASM磁盘组

su – grid
$asmca

添加OCR磁盘组
[root@rac1 ~]# ocrconfig -add +dggrid2
[root@rac1 ~]# ocrcheck

10.安装数据库软件

su – oracle
export LANG=en_US
./runInstaller

11.创建数据库

$dbca

SGA大小设置为物理内存的45%~55%
PGA大小设置为物理内存的80%的20%

数据文件不要超过30G
每个表空间设置20G，取消自动扩展

日志文件
至少8个组 每个redo 200m

12.调整归档

SQL> alter system set cluster_database=FALSE scope=spfile;

System altered.

关闭数据库
srvctl stop database –d racdb12c –o immediate

启动1节点数据库
SQL>startup mount

SQL> alter system set log_archive_dest_1='location=+DGRECOVER' scope=spfile;

System altered.

SQL>alter database archivelog;

重启数据库
srvctl start database –d racdb12c

修改sqlnet.ora,使其他版本客户端可以连接12c数据库
SQLNET.ALLOWED_LOGON_VERSION_SERVER=10
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=10
