首先，准备好网络、主机名、存储等相关配置，以下会跳过相关程度不大的步骤

2.4 创建用户和组

要确保每个节点的用户和组有相同的UID和GID

点击(此处)折叠或打开

groupadd oinstall
groupadd dba
groupadd oper
useradd -u 200 -g oinstall -G dba,oper oracle
passwd oracle

配置用户等效性

以oracle用户登录

点击(此处)折叠或打开

mkdir ~/.ssh
chmod 700 ~/.ssh
ssh-keygen -t rsa
ssh-keygen -t dsa
#在所有节点完成后继续以下
touch ~/.ssh/authorized_keys
cd ~/.ssh
ssh node1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
ssh node1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
ssh node2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
ssh node2 cat /home/oracle/.ssh/id_dsa.pub >>authorized_keys
scp authorized_keys node2:/home/oracle/.ssh/

在所有节点上配置完后，验证：

点击(此处)折叠或打开

ssh node1 date
ssh node2 date

2.5 配置用户环境变量

点击(此处)折叠或打开

vi .bash_profile

export ORACLE_SID=racdb

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/local/lib

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin/:/usr/local/bin:/usr/X11R6/bin:$PATH

export NLS_LANG='american_america.zhs16gbk'

export NLS_DATE_FORMAT='dd-mm-yy hh24:mi:ss'

export ORACLE_TERM=vt100

export LANG="en_US.UTF-8"

2.7 配置/etc/hosts
