First, install the operating system (slightly)Note that I use the Oel 5u5 version here because it comes with the environment variable installation package provided by Oracle, so it is easy to install the Oracle software, so it is recommended to use this version
Second, configure local Yum source
--mount the mounting plate to mediamount-t Iso9660/dev/cdrom/media
--Configure repos Add the following vi/etc/yum.repos.d/oel5.repos[oel5]name = Oel 5 Dvdbasurl = File:///media/Servergpgcheck =0enabled = 1--1 means enable this repos
Iii. Configuring Trust Relationships (Oracle users)
--Node 1 and Node 2 are executed separately:ssh-keygen-t RSAssh-keygen-t DSA
--Node 1 execution:cat ~/.ssh/*.pub >> ~/.ssh/authorized_keysssh rac2 cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys SCP ~/.ssh/authorized_keys Rac2:~/.ssh/authorized_keys
In short, the 2-side node information is written to the public key file, and then ssh with each other no longer need the password, because the RAC installation needs to copy files between the nodes
--Authentication Node 1 execution: SSH rac1 datessh rac2 datessh rac1-priv datessh rac2-priv Date
Node 2 execution: SSH rac1 datessh rac2 datessh rac1-priv datessh rac2-priv Date
Multiple authentication several times, until no need to enter the password, here to pay attention to Authorized_keys do not miss S, I have tried for a long time also did not succeed, finally found that the public key file name is wrong, less a s caused by
iv. Configuring shared disks
--Add several block disks and partition FDISK-LFDISK/DEV/SDBFDISK/DEV/SDCFDISK/DEV/SDDFDISK/DEV/SDE
If you encounter the need to restart to identify the partition information, you can use the Linux partporbe command, you can do it without restarting to let kernel recognize the new partition can also perform partprobe-s to view
[Email protected] ~]#FDISK/DEV/SDC

Just add the Red section and restart Udev,when configured correctly, the following is displayed:

vi. installation of Clusterware
--Before the pre-installation checkCD./clusterware/cluvfy
./cluvfy.sh-stage Pre crsinst-n Rac1,rac2-verbose
Will list a lot of content, detect whether to meet the conditions of installing clusterware, which need to install a compat_db package separately, oracle-validated package will not install this will also report a few other COMPAT packet detection failure is ignored, Because it's just the wrong version. If you encounter other content that is not passed, you need to deal with it until you pass all but the above errors.
--Start the installation CD./clusterware
./RUNINSTALL-IGNORESYSPREREQS (parameter can ignore case, command does not allow)
Running Oui to the end will require 2 scripts to be executed at 2 nodes, in the order of:Script 1:rac1->rac2Script 2:rac1->rac2The first 3 executions are no problem, to the 4th step, the execution of root.sh on Node 2, will be error:

You need to wait a few minutes (90s+600s), and then an error occurs because of a bug in Oracle on 10.2.0.1, the workaround is toModify $ora_crs_home/bin full VIPCA and Srvctl files, add unset ld_assume_kernel Save at the end of the file, and then re-execute Node 2 root.sh

At this time because there is no VIP configured, so no resources are registered, go to any node to run VIPCA (if the node's VIPCA has been modified), if the following error is reported:
[email protected] bin]$ VIPCAError 0 (native:listnetinterfaces:[3])[Error 0 (native:listnetinterfaces:[3])]
Then you need to configure the network card: [[email protected] bin]$./oifcfg iflisteth0 192.168.1.0eth1 10.0.0.0[Email protected] bin]$/oifcfg getif[[email protected] bin]$./oifcfg Setif-global eth0/192.168.1.0:public[Email protected] bin]$./oifcfg Setif-global eth1/10.10.10.1:cluster_interconnect[Email protected] bin]$/oifcfg getifeth0 192.168.1.0 Global Publiceth1 10.10.10.1 Global Cluster_interconnect
Note that you have permission to open the GUI and use the root user to execute VIPCA instead of the Oracle user, otherwise you will be reporting insufficient permissions [[email protected] bin]$ vipcainsufficient privileges. Insufficient privileges.
Then will jump out of the VIP Configuration Assistant Oui interface, start to configure VIP, enter the VIP node alias will automatically fill the VIP IP address (process slightly) run out of VIPCA after the exit, execute Crs_stat again, you will find that the resources have been registered to the CRS [email protected] bin]#./crs_stat-tname Type Target state Host ----------------------------------------------------- -------ORA.RAC1.GSD Application online online &NBSP;RAC1 &NBS P;ora.rac1.ons Application online online &NBSP;RAC1 ora .
