ASM磁盘组 |
OCRVT: 2G * 3 MGMT: 40G * 1 DATA: 8G * 1 ARCH: 5G * 1 |
安装操作系统，添加ASM共享磁盘省略
第二分部 操作系统环境配置
2.1 更改IO调度为deadline，关闭numa和透明大页
（1）.vi /etc/default/grub(编辑 /etc/default/grub 文件，在GRUB_CMDLINE_LINUX 条目后面添加"elevator=deadline","transparent_hugepage=never" 和”numa=off”，
执行grub2-mkconfig -o /boot/grub2/grub.cfg 最后重启操作系统)
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=rootvg/root rd.lvm.lv=rootvg/swap rhgb quiet elevator=deadline transparent_hugepage=never numa=off net.ifnames=0 biosdevname=0"
grub2-mkconfig -o /boot/grub2/grub.cfg
（2）. 重启操作系统使配置生效.
2.2 使用CTSS时钟同步
/sbin/service ntpd stop
chkconfig ntpd off
mv /etc/ntp.conf /etc/ntp.conf.org
systemctl stop chronyd
systemctl disable chronyd
2.3 配置/etc/hosts解析表
vi /etc/hosts添加
#config for 18c RAC
192.168.56.11 rac1
192.168.56.12 rac2
192.168.56.13 rac1-vip
192.168.56.14 rac2-vip
172.16.56.11 rac1-priv
172.16.56.12 rac2-priv
192.168.56.15 rac-scan
2.4 关闭防火墙
systemctl disable firewalld.service
systemctl stop firewalld.service
2.5 关闭selinux
vi /etc/selinux/config
SELINUX=disabled
2.6 关闭NetworkManager
systemctl disable NetworkManager
systemctl stop NetworkManager
2.7 停止avahi-daemon
systemctl stop avahi-daemon.socket avahi-daemon.service
systemctl disable avahi-daemon.socket avahi-daemon.service
2.8 配置NOZEROCONF
vi /etc/sysconfig/network 添加
NOZEROCONF=yes
2.9 内核参数修改
vi /etc/sysctl.conf
#kernel configuration for oracle 18c
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 268435456
kernel.shmmax = 549755813760
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
是配置生效
sysctl -p
2.10 添加用户和组
/usr/sbin/groupadd -g 54321 oinstall
/usr/sbin/groupadd -g 54322 dba
/usr/sbin/groupadd -g 54323 oper
/usr/sbin/groupadd -g 54324 backupdba

/usr/sbin/useradd -u 54321 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba,oper oracle
/usr/sbin/useradd -u 54322 -g oinstall -G asmadmin,asmdba,racdba,asmoper grid
echo oracle | passwd --stdin oracle
echo oracle | passwd --stdin grid
2.11 创建软件安装目录
mkdir -p /u01/app/18.0.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle/product/18.0.0/db_1
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/
2.12 用户环境变量配置
#为grid用户添加环境变量
vi /home/grid/.bash_profile EOF
export ORACLE_BASE=/u01/app/grid
export ORACLE_SID=+ASM1 (节点2改为+ASM2)
export ORACLE_HOME=/u01/app/18.0.0/grid

(1).多路径方式安装配置
yum -y install device-mapper*
--生成默认配置文件
mpathconf --enable
vi /etc/multipath.conf 修改

第三部分 安装GRID软件
3.1 解压软件
unzip LINUX.X64_180000_grid_home.zip -d /u01/app/18.0.0/grid
3.2 配置用户ssh对等性（方便检查rac2节点配置，也可以OUI界面配置）
su - grid
cd /u01/app/18.0.0/grid/oui/prov/resources/scripts
./sshUserSetup.sh -user grid -hosts "rac1 rac2" -advanced –noPromptPassphrase
3.3 安装前环境预检查
su - grid
cd /u01/app/18.0.0/grid
./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -fixup –verbose
3.4 开始安装grid软件
export DISPLAY=192.168.56.1:0.0
cd /u01/app/18.0.0/grid
./gridSetup.sh
分别在rac1，rac2执行上面2个脚本
执行完成后，点击OK继续完成安装。
INS-20802 报错可以忽略
至此grid软件安装完成。
第四部分 创建ASM磁盘组
su - grid
export DISPLAY=192.168.56.1:0.0
asmca
创建DATA和ARCH磁盘组
第五部分 安装database软件
5.1 解压db软件
su - oracle
unzip /soft/LINUX.X64_180000_db_home.zip –d /u01/app/oracle/product/18.0.0/db_1
5.2 开始安装db软件
su - oracle
export DISPLAY=192.168.56.1:0.0
cd /u01/app/oracle/product/18.0.0/db_1
./runInstaller
如果前面没有配置oracle用户的ssh对等性，则输入oracle用户密码，点击setup进行配置
分别在rac1，rac2节点执行/u01/app/oracle/product/18.0.0/db_1/root.sh脚本
至此database软件安装完成。
第六部分 创建数据库
su - oracle
export DISPLAY=192.168.56.1:0.0
dbca
至此dbca创建数据库完成。
