3. 创建用户，组

[root@oracle_node1 ~]# /usr/sbin/groupadd -g 501 oinstall
[root@oracle_node1 ~]# /usr/sbin/groupadd -g 502 dba
[root@oracle_node1 ~]# /usr/sbin/groupadd -g 503 oper
[root@oracle_node1 ~]# /usr/sbin/groupadd -g 504 asmadmin
[root@oracle_node1 ~]# /usr/sbin/groupadd -g 505 asmdba
[root@oracle_node1 ~]# /usr/sbin/groupadd -g 506 asmoper
[root@oracle_node1 ~]# /usr/sbin/useradd -u 501 -g oinstall -G dba,asmdba,oper oracle
[root@oracle_node1 ~]# /usr/sbin/useradd -u 502 -g oinstall -G asmadmin,asmdba,asmoper,dba grid
[root@oracle_node1 ~]# passwd oracle
[root@oracle_node1 ~]# passwd grid
[root@oracle_node1 ~]# mkdir -p /u01/app/oracle
[root@oracle_node1 ~]# mkdir -p /u01/app/oracle/product/12.1.0/db_1
[root@oracle_node1 product]# mkdir -p /u01/app/grid
[root@oracle_node1 product]# mkdir -p /u01/app/12.1.0/grid
[root@oracle_node1 product]# mkdir -p /u01/app/oraInventory
[root@oracle_node1 product]# chown -R oracle:oinstall /u01/app/oracle
[root@oracle_node1 product]# chown -R grid:oinstall /u01/app/grid
[root@oracle_node1 product]# chown -R grid:oinstall /u01/app/oraInventory
[root@oracle_node1 app]# chown -R grid:oinstall /u01/app/12.1.0/

4. 环境变量

[oracle@oracle_node1 ~]$ vi .bash_profile
PATH=$PATH:$HOME/bin

export PATH
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
export ORACLE_UNQNAME=orcl
export ORACLE_SID=orcl1
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH:$ORACLE_BASE/scripts12c
stty erase ^H

[grid@oracle_node1 ~]$ vi .bash_profile

PATH=$PATH:$HOME/bin

export PATH
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/12.1.0/grid
export ORACLE_SID=+ASM1
export PATH=$ORACLE_HOME/bin:$PATH
umask 022

5. 资源限制

[root@oracle_node1 ~]# vi /etc/security/limits.conf
root  soft  nofile  65536
root  hard  nofile  65536
* soft memlock unlimited
* hard memlock unlimited
grid  soft  nproc  65536
grid  hard  nproc  65536
grid  soft  nofile 65536
grid  hard  nofile 65536
oracle soft nproc  65536
oracle hard nproc  65536
oracle soft nofile 65536
oracle hard nofile 65536
#Oracle recommended value for stack is set to 10240 for user grid
grid  soft  stack  10240
#Oracle recommended value for stack is set to 10240 for user oracle
oracle  soft  stack  10240

6. 配置ssh互信 Oracle_123

oracle,grid都要执行
./sshUserSetup.sh -user grid -hosts "oracle-node3 oracle-node4" -advanced –noPromptPassphrase
./sshUserSetup.sh -user oracle -hosts "oracle-node3 oracle-node4" -advanced –noPromptPassphrase

Oracle_123

7. 配置共享存储

--磁盘分区
fdisk /dev/sdd >u>n>p>1>default>default>w
--编译rules文件
--查看scsi_id
[root@oracle-node3 ~]# /usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/sdd1  
3600144f0593d8f320000598134750007
touch /etc/udev/rules.d/99-oracle-asmdevices.rules

[root@oracle-node3 ~]# vi /etc/udev/rules.d/99-Oracle-asmdevices.rules
KERNEL=="sd*", ENV{ID_SERIAL}=="3600144f0593d8f320000598134750007",SYMLINK+="asm_data", OWNER="grid", GROUP="asmadmin", MODE="0660"
--使udev生效
[root@oracle-node3 ~]# udevadm control --reload-rules  
[root@oracle-node3 ~]# udevadm trigger
