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
[root@rac12c1~]# passwd oracle [root@rac12c1~]# passwd grid
确保oracle是oper，asmdba组成员
[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 grid soft nproc 16384 grid hard nproc 16384 grid soft stack 10240 grid hard stack 32768 grid hard memlock 134217728 grid soft memlock 134217728 # # # Oracle user oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 16384 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 32768 oracle hard memlock 13217728 oracle soft memlock 134217728 # End of file

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 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
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
