#SCAN
172.16.30.225 rac12c-scan.localdomain rac12c-scan
禁用Selinux：
[root@rac12c1 ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@rac12c1 ~]# setenforce 0
修改/dev/shm大小为8G
tmpfs /dev/shm tmpfs rw,exec,size=2048M 0 0
[root@rac12c1 ~]# mount -o remount /dev/shm/
禁用防火墙：
[root@rac12c1 ~]# systemctl start firewalld.service
[root@rac12c1 ~]# systemctl stop firewalld.service
[root@rac12c1 ~]# ]# systemctl disable firewalld.service
rm '/etc/systemd/system/basic.target.wants/firewalld.service'
rm '/etc/systemd/system/dbus-org.Fedoraproject.FirewallD1.service'
重启各个节点操作系统，检查各个节点网络连通性：

[root@rac12c1 ~]# ping rac12c2pri
[root@rac12c1 ~]# ping rac12c2
，，，
配置YUM:
[root@rac12c1 ~]# cat /etc/yum.repos.d/base.repo
[ol7_latest]
name=Oracle Linux $releasever Latest ($basearch)
baseurl=file:///mnt
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=0
enabled=1
安装oracle相关的依赖包：
[root@rac12c1 ~]# yum install oracle-rdbms-server-12cR1-preinstall –y
创建用户组和用户，上步操作依据创建了oinstall 54321 dba 54322用户组）和用户oracle（54321），所以执行如下操作创建相关的用户组和用户
添加组
[root@rac12c1 ~]# groupadd -g 54323 oper
[root@rac12c1 ~]# groupadd -g 54325 asmdba
[root@rac12c1 ~]# groupadd -g 54328 asmadmin
[root@rac12c1 ~]# groupadd -g 54329 asmoper
添加grid用户
[[root@rac12c1 ~]# useradd -u 54322 -g oinstall -G dba,asmdba,asmadmin,asmoper grid
为oracle和grid用户设置密码
1
2
[[root@rac12c1 ~]#passwd oracle
[root@rac12c1 ~]# passwd grid
确保oracle是oper，asmdba组成员
1
[root@rac12c1 ~]# usermod -g oinstall -G dba,oper,asmdba oracle
修改用户资源限制:grid soft nofile 1024
grid hard nofile 65536

[root@rac12c1 ~]# /etc/init.d/oracleasm configure -i
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
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]: grid
Default group to own the driver interface [asmadmin]: asmadmin
Scan for Oracle ASM disks on boot (y/n) [y]: y
