HISTTIMEFORMAT="%Y:%M:%D %H-%m-%s"
export=HISTTIMEFORMAT
[root@rac1 ~]# source .bash_profile
4 grid和oracle 的bash文件
[grid@rac1 ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=+ASM1
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
umask 022
[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ vi .bash_profile
[root@rac1 ~]# cat /home/oracle/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=bol1
export ORACLE_UNQNAME=bol
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
$ source .bash_profile使配置文件生效
[root@rac1 ~]# source /home/grid/.bash_profile
[root@rac1 ~]# source /home/oracle/.bash_profile
5 克隆主机rac1并修改
克隆并配置虚拟主机rac2 或者重新配置rac2
[root@rac2 ~]# cat /home/grid/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=+ASM2
export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/11.2.0/grid
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
umask 022
export PATH
[root@rac2 ~]# cat /home/oracle/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=bol2
export ORACLE_UNQNAME=bol
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export PATH
6 配置ssh等效性
各节点生成Keys:
[root@rac1 ~]# su - oracle
[oracle@rac1 ~]$ mkdir ~/.ssh
[oracle@rac1 ~]$ chmod 700 ~/.ssh
[oracle@rac1 ~]$ ssh-keygen -t rsa
[oracle@rac1 ~]$ ssh-keygen -t dsa
[root@rac2 ~]# su - oracle
[oracle@rac2 ~]$ mkdir ~/.ssh
[oracle@rac2 ~]$ chmod 700 ~/.ssh
[oracle@rac2 ~]$ ssh-keygen -t rsa
[oracle@rac2 ~]$ ssh-keygen -t dsa
在节点1上进行互信配置:
[oracle@rac1 ~]$ touch ~/.ssh/authorized_keys
[oracle@rac1 ~]$ cd ~/.ssh
[oracle@rac1 .ssh]$ ssh rac1 cat ~/.ssh/id_rsa.pub >> authorized_keys
[oracle@rac1 .ssh]$ ssh rac2 cat ~/.ssh/id_rsa.pub >> authorized_keys
[oracle@rac1 .ssh]$ ssh rac1 cat ~/.ssh/id_dsa.pub >> authorized_keys
[oracle@rac1 .ssh]$ ssh rac2 cat ~/.ssh/id_dsa.pub >> authorized_keys
在rac1把存储公钥信息的验证文件传送到rac2上
[oracle@rac1 .ssh]$ pwd
/home/oracle/.ssh
[oracle@rac1 .ssh]$ scp authorized_keys oracle@10.15.7.12:/home/oracle/.ssh/.
设置验证文件的权限
在每一个节点执行:
$ chmod 600 ~/.ssh/authorized_keys
启用用户一致性
在你要运行OUI的节点以oracle用户运行(这里选择rac1):
[oracle@rac1 .ssh]$ exec /usr/bin/ssh-agent $SHELL
[oracle@rac1 .ssh]$ ssh-add
Identity added: /home/oracle/.ssh/id_rsa (/home/oracle/.ssh/id_rsa)
Identity added: /home/oracle/.ssh/id_dsa (/home/oracle/.ssh/id_dsa)
验证ssh配置是否正确
以oracle用户在所有节点分别执行:
ssh rac1 date
ssh rac2 date
ssh rac1priv date
ssh rac2priv date
===========
[oracle@rac1 .ssh]$ su - grid
Password:
[grid@rac1 ~]$ mkdir ~/.ssh
[grid@rac1 ~]$ ssh-keygen -t rsa
[grid@rac1 ~]$ ssh-keygen -t dsa
[grid@rac1 ~]$ chmod 700 ~/.ssh
[oracle@rac2 .ssh]$ su - grid
Password:
[grid@rac2 ~]$ mkdir ~/.ssh
[grid@rac2 ~]$ ssh-keygen -t rsa
[grid@rac2 ~]$ ssh-keygen -t dsa
[grid@rac2 ~]$ chmod 700 ~/.ssh
[grid@rac1 ~]$ touch ~/.ssh/authorized_keys
[grid@rac1 ~]$ cd ~/.ssh
[grid@rac1 .ssh]$ ssh rac1 cat ~/.ssh/id_rsa.pub >> authorized_keys
[grid@rac1 .ssh]$ ssh rac2 cat ~/.ssh/id_rsa.pub >> authorized_keys
[grid@rac1 .ssh]$ ssh rac1 cat ~/.ssh/id_dsa.pub >> authorized_keys
[grid@rac1 .ssh]$ ssh rac2 cat ~/.ssh/id_dsa.pub >> authorized_keys
[grid@rac1 .ssh]$ scp authorized_keys grid@rac2:/home/grid/.ssh/.
[grid@rac1 .ssh]$ exec /usr/bin/ssh-agent $SHELL
[grid@rac1 .ssh]$ ssh-add
Identity added: /home/grid/.ssh/id_rsa (/home/grid/.ssh/id_rsa)
Identity added: /home/grid/.ssh/id_dsa (/home/grid/.ssh/id_dsa)
[grid@rac1 .ssh]$
ssh rac1 date
ssh rac2 date
ssh rac1priv date
ssh rac2priv date
[grid@rac2 .ssh]$
ssh rac1 date
ssh rac2 date
ssh rac1priv date
ssh rac2priv date
7 配置共享存储

/usr/bin/xterm -ls -display $DISPLAY
=[INS-41104]存在找不到private网卡,
几番试过之后,把eth1删除,然后重启,ifconfig找到eth1的hwaddr,cp eth0 eth1 ,并修改hwaddr和ipaddr,device,name,注释uuid
