小编给大家分享一下RHEL7.3如何安装oracle12c 单点grid和rdbms，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
##安装桌面
yum -y groupinstall "Server with GUI"
#启动桌面
startx
#设置启动模式
[root@localhost ~]# systemctl get-default
multi-user.target
[root@localhost ~]# cat /etc/inittab
# inittab is no longer used when using systemd.
#
# ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# Ctrl-Alt-Delete is handled by /usr/lib/systemd/system/ctrl-alt-del.target
#
# systemd uses 'targets' instead of runlevels. By default, there are two main targets:
#
# multi-user.target: analogous to runlevel 3 #多用户模式
# graphical.target: analogous to runlevel 5 #图形化模式
#
# To view current default target, run:
# systemctl get-default
#
# To set a default target, run:
# systemctl set-default TARGET.target
#
[root@localhost ~]# systemctl set-default graphical.target
Removed symlink /etc/systemd/system/default.target.
Created symlink from /etc/systemd/system/default.target to /usr/lib/systemd/system/graphical.target.
[root@localhost ~]# systemctl get-default
graphical.target
##创建用户和组
groupadd -g 500 oinstall
groupadd -g 501 dba
groupadd -g 502 oper
groupadd -g 600 asmadmin
groupadd -g 601 asmdba
groupadd -g 602 asmoper
useradd -u 1000 -g oinstall -G dba,oper,asmdba oracle
useradd -u 1001 -g oinstall -G dba,asmdba,asmadmin,asmoper grid

/sbin/sysctl -p
##官方文档对shmmax的设置解释，(文档 ID 567506.1)，我一般直接使用当前设置/sbin/sysctl -a | grep shm
#Oracle Global Customer Support officially recommends a " maximum" for SHMMAX of "1/2 of physical RAM".
#The maximum size of a shared memory segment is limited by the size of the available user address space. On 64-bit systems, this is a theoretical 2^64bytes. So the "theoretical limit" for SHMMAX is the amount of physical RAM that you have. However, to actually attempt to use such a value could potentially lead to a situation where no system memory is available for anything else. Therefore a more realistic "physical limit" for SHMMAX would probably be "physical RAM - 2Gb".
#In an Oracle RDBMS application, this "physical limit" still leaves inadequate system memory for other necessary functions. Therefore, the common "Oracle maximum" for SHMMAX that you will often see is "1/2 of physical RAM". Many Oracle customers chose a higher fraction, at their discretion.
#Occasionally, Customers may erroneously think that that setting the SHMMAX as recommended in this NOTE limits the total SGA. That is not true. Setting the SHMMAX as recommended only causes a few more "shared memory segments" to be used for whatever total SGA that you subsequently configure in Oracle. For additional detail, please see

vi /etc/security/limits.conf

##创建安装目录
mkdir -p /u01/app/grid
mkdir -p /u01/app/gridhome
mkdir -p /u01/app/oracle
chown grid:oinstall /u01/app/grid
chown grid:oinstall /u01/app/gridhome
chown -R oracle:oinstall /u01/app/oracle
##修改hosts文件，<enp0s8>网卡名称
ip add | grep enp0s8 | grep inet | awk '{print $2}' | awk -F"/" '{printf $1" "}{cmd="hostname";system(cmd)}' >> /etc/hosts
cat /etc/hosts
##关闭防火墙和selinux
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
[root@rhel7ora11 ~]# getenforce
Enforcing
[root@rhel7ora11 ~]# setenforce 0
[root@rhel7ora11 ~]# getenforce
Permissive
[root@rhel7ora11 ~]# vi /etc/selinux/config
SELINUX=disabled
或
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
##udev绑定裸设备,这里只绑定权限
[root@rhel7-ora12c-ip156 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdb1

[root@rhel7-ora12c-ip156 ~]# systemctl restart systemd-udev-trigger.service

##设置用户参数文件
su - grid
export ORACLE_BASE=/u01/app/grid

##安装cvuqdisk
[root@rhel7-ora12c-ip156 gridhome]# rpm -ivh ./cv/rpm/cvuqdisk-1.0.10-1.rpm
##编辑ohas文件，在执行root.sh脚本以后一直监控/etc/init.d/init.ohasd文件，文件存在马上启动ohas服务
[root@rhel7-ora12c-ip156 ~]# vi /usr/lib/systemd/system/ohas.service
[Unit] Description=Oracle High Availability Services After=syslog.target [Service] ExecStart=/etc/init.d/init.ohasd run >/dev/null 2>&1 Type=simple Restart=always [Install] WantedBy=multi-user.target |
[root@rhel7-ora12c-ip156 ~]# chmod 777 /usr/lib/systemd/system/ohas.service
##执行root脚本以后，一直检查下面的文件是否存在，当文件存在马上手动启动oha，推介
[root@rhel7-ora12c-ip156 ~]# ls /etc/init.d/init.ohasd
/etc/init.d/init.ohasd
[root@rhel7-ora12c-ip156 ~]# systemctl start ohas.service
