linux下Oracle11g RAC搭建（六）
五、校验安装前的环境
root身份下完成解压grid、database安装包
[grid@node1 soft]$ su -
Password:
[root@node1 ~]# cd /soft
[root@node1 soft]# ls
asm linux_11gR2_database_1of2.zip linux_11gR2_database_2of2.zip linux_11gR2_grid.zip
[root@node1 soft]# unziplinux_11gR2_grid.zip
[root@node1 soft]# unziplinux_11gR2_database_1of2.zip
[root@node1 soft]# unziplinux_11gR2_database_2of2.zip
grid 身份下校验安装环境
[root@node1 soft]#su – grid
[grid@node1 ~]$ cd /soft/grid
[grid@node1 grid]$ ./runcluvfy.shstage -pre crsinst -nnode1,node2 -fixup -verbose
//pre-安装前，post-安装后，阶段名称叫crsinst-crsinstall，-n-节点之间校验，verbose-校验的过程
检测crs安装环境(node1、node2)，安装失败的包如下：
sysstat-7.0.2
unixODBC-2.2.11
unixODBC-devel-2.2.11
libaio-devel-0.3.106
详细列表如下：
Check: Package existence for "sysstat-7.0.2"
Node Name Available Required Comment
------------ ------------------------ ------------------------ ----------
node2 missing sysstat-7.0.2 failed
node1 missing sysstat-7.0.2 failed
Result: Package existence check failed for"sysstat-7.0.2"
Check: Package existence for "unixODBC-2.2.11"

Check: Package existence for "unixODBC-devel-2.2.11"

------------ ------------------------ ------------------------ ----------
node2 missing unixODBC-devel-2.2.11 failed
node1 missing unixODBC-devel-2.2.11 failed
Check: Package existence for "libaio-devel-0.3.106"
Node Name Available Required Comment
------------ ------------------------ ------------------------ ----------
node2 missing libaio-devel-0.3.106 failed
node1 missing libaio-devel-0.3.106 failed
补充：
若出现swap分区大小不足，参考如下更改：
[root@hylbest1 localdisk]# dd if=/dev/zeroof=/localdisk/swapfile bs=1024 count=4096000
[root@hylbest1 localdisk]# mkswap/localdisk/swapfile
[root@hylbest1 localdisk]# swapon/localdisk/swapfile
[root@hylbest1 localdisk]# vi/etc/fstab
添加/localdisk/swapfile swap swap defaults 0 0
[root@hylbest1 localdisk]# cat/proc/swaps
查看swap详细：
Filename Type Size Used Priority
/dev/mapper/VolGroup00-LogVol01 partition 2097144 136 -1
/localdisk/swapfile file 4095992 0 -2
配置yum install安装工具（node1、node2）
为node1配置yum
yum工具：可以自动解决软件包之间的依赖关系，使用它之前要先创建软件仓库。
以下，开始构建软件仓库：
[root@node1 grid]$ su –
[root@node1 ~]# cd/etc/yum.repos.d/ //进入到该目录下生成一个配置文件
[root@node1 yum.repos.d]# ls
[root@node1 yum.repos.d]# cprhel-debuginfo.repo yum.repo
//做一个拷贝
[root@node1 yum.repos.d]# mv rhel-debuginfo.repo rhel-debuginfo.repo.bak
//修改原来文件名
[root@node1 yum.repos.d]#vi yum.repo
//文件内容改为如下
修改如下：
[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
说明：
media这个就是安装光盘挂载所在位置，Server下就是一些安装包，S是大写。
enabled=1表示启动，gpgcheck=0表示校验关闭。
为node2配置yum
[root@node1 yum.repos.d]# scpyum.repo node2:/etc/yum.repos.d
//把yum.repo拷贝到node2
根据校验结果使用yum安装缺失软件包（node1、node2）
Vbox中挂载IOS光盘（node1、node2）
[root@node1 yum.repos.d]#mount/dev/hdc /media 或者mount /dev/cdrom /media
//vbox设置完毕后，手工挂载光盘
[root@node1 yum.repos.d]# ls /media/ //可以查看一下目录下文件
[root@node1 yum.repos.d]# ls/media/Server|more
//再看一下server下应该有很多软件包
至此，yum仓库构建完成。

安装node2中缺失的软件包
Vbox中挂载IOS光盘（node1、node2）
[root@node2 ~]#mount/dev/hdc /media 或者mount /dev/cdrom /media
//vbox设置完毕后，手工挂载光盘
参考“安装node1中缺失的软件包”
grid身份下再次校验安装环境
重新启动node1、node2系统，在node1以grid身份再次完成环境校验（“参考grid身份下校验安装环境”）
