Oracle 11gR2构建RAC之(3)--安装grid前环境检测
系统环境:
操作系统:RedHat EL5
Cluster: Oracle GI(Grid Infrastructure)
Oracle: Oracle 11.2.0.1.0
如图所示:RAC 系统架构
三、安装GI之前,可以以grid用户的身份对环境进行检测。
以grid 用户的身份校验安装环境(在grid的安装软件包目录下)

[grid @node1 grid]$ ./runcluvfy.sh stage -pre crsinst -n node1,node2 -fixup -verbose
---在检测中会提示,“failed”的位置,需要fixup.
1 、需要安装的软件包(all nodes)
配置yum安装环境: [root @node1 yum.repos.d]# cp rhel-debuginfo.repo yum.repo
[root @node1 yum.repos.d]# ls
rhel-debuginfo.repo yum.repo [root @node1 yum.repos.d]# cat yum.repo
[Base] name=Red Hat Enterprise Linux baseurl=file: ///media/Server
enabled= 1
gpgcheck= 0
gpgkey=file: ///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
挂载linux ISO 光盘: [root @node1 yum.repos.d]#mount /dev/hdc /media
安装软件: libaio-devel.i386 0 : 0.3 . 106 - 5 sysstat.i386 0 : 7.0 . 2 - 3 .el5
unixODBC- 2.2 . 11 - 7.1
unixODBC-devel- 2.2 . 11 - 7.1
unixODBC-kde- 2.2 . 11 - 7.1
2 、配置用户之间的信任关系(oracle和grid)
建立节点之间oracle 、grid 用户之间的信任(通过ssh 建立公钥和私钥) =====Oracle========== 1 )生成**对(all nodes)
[oracle @node1 ~]$ ssh-****** -t rsa
Generating public / private rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa): Enter passphrase (empty for no passphrase):
Enter same passphrase again: Your identification has been saved in /home/oracle/.ssh/id_rsa. Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
The key fingerprint is: 64 :a6:4a: 77 :db: 33 :a4:aa:6e:ca:8f:5f:2f: 77 :0f: 40 oracle @node1
[oracle @node1 ~]$ ssh-****** -t dsa
Generating public / private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa): Enter passphrase (empty for no passphrase):
Enter same passphrase again: Your identification has been saved in /home/oracle/.ssh/id_dsa. Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is: 7c: 41 :b5:0f: 81 : 06 :ad: 30 : 07 :4f:8b:1a:9b: 94 : 68 : 14 oracle @node1
2 )配置信任关系
[oracle @node1 ~]$ ls .ssh
id_dsa id_dsa.pub id_rsa id_rsa.pub known_hosts [oracle @node1 ~]$ cat .ssh/id_rsa.pub >>.ssh/authorized_keys
[oracle @node1 ~]$ cat .ssh/id_dsa.pub >>.ssh/authorized_keys
[oracle @node1 ~]$ ssh node2 cat .ssh/id_rsa.pub >>.ssh/authorized_keys
oracle @node2 's password:
[oracle @node1 ~]$ ssh node2 cat .ssh/id_dsa.pub >>.ssh/authorized_keys
oracle @node2 's password:
[oracle @node1 ~]$ scp .ssh/authorized_keys node2:~/.ssh
oracle @node2 's password:
authorized_keys 100 % 1992 2 .0KB/s 00 : 00 3 )验证信任关系 (all nodes)
[oracle @node1 ~]$ ssh node2 date
Thu May 2 14 : 46 : 30 CST 2013
[oracle @node1 ~]$ ssh node2-priv date
The authenticity of host 'node2-priv (10.10.10.2)' can't be established.
RSA key fingerprint is 16 : 28 : 88 : 50 : 27 : 30 : 92 :cb: 49 :be: 55 : 61 :f6:c2:a1:3f.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'node2-priv,10.10.10.2' (RSA) to the list of known hosts.
Thu May 2 14 : 47 : 03 CST 2013
[oracle @node1 ~]$ ssh node1 date
Thu May 2 14 : 48 : 19 CST 2013
[oracle @node1 ~]$ ssh node1-priv date
The authenticity of host 'node1-priv (10.10.10.1)' can't be established.
RSA key fingerprint is 39 : 04 : 88 :3b: 54 : 34 :3c: 34 :d2:df: 74 : 37 :fe:5f: 92 :2d.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'node1-priv,10.10.10.1' (RSA) to the list of known hosts.
Thu May 2 14 : 48 : 35 CST 2013
=========grid=========== 步骤同oracle 一样 @至此,GI安装之前的准备工作基本完成。
