Exadata是Oracle软硬结合的一体机。通过自己的机子不可能全然模拟出来,这里搭建的虚拟机仅仅是一个简单的、能够供我们学习Exadata的环境。

最简单能够模拟的Exadata虚拟机须要两个节点,CELL节点和DB节点。

首先说一下CELL节点安装介质:

OEL5.6-x86-64

cell-11.2.3.3.1_LINUX.X64

这两个在https://edelivery.oracle.com/ 能够下载的到

以下是详细安装步骤:

关闭UEK。否则启动cellsrv会报错:

[root@CELL ~]# vi /etc/grub.conf

# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE:  You have a /boot partition.  This means that

#          all kernel and initrd paths are relative to /boot/, eg.

#          root (hd0,0)

#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00

#          initrd /initrd-version.img

#boot=/dev/sda

timeout=5

splashimage=(hd0,0)/grub/splash.xpm.gz

hiddenmenu

。。

。。

略。

重新启动系统:

[root@CELL ~]# reboot

hosts文件配置例如以下:

[root@CELL ~]# cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.90.151 CELL

网卡配置例如以下:

[root@CELL ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)

DEVICE=eth0

BOOTPROTO=static

IPV6INIT=yes

IPV6_AUTOCONF=yes

NETMASK=255.255.255.0

NETWORK=192.168.90.0

ONBOOT=yes

使用oracle-validated安装一些rpm包

[root@CELL ~]# vi /etc/yum.repos.d/public-yum-el5.repo

上传介质后解压:

[root@CELL soft]# tar -pxvf cellImageMaker_11.2.3.3.1_LINUX.X64_140708-1.x86_64.tar

ip配置好后依旧报错

alert日志位置:

/opt/oracle/cell11.2.3.3.1_LINUX.X64_140708/log/diag/asm/cell/CELL/trace/alert.log

从中能够看到下面内容:

The minimum number is 16384. Please change ulimit

CELLSRV boot failed to start due to the error 11 (Not enough open file descriptors)

接下来我们调整限制:

[root@CELL ~]# vi /etc/sysctl.conf

最后一行加入:

fs.file-max = 65536

生效一下:

[root@CELL ~]# sysctl -p

net.ipv4.ip_forward = 0

net.ipv4.conf.default.rp_filter = 2

net.ipv4.conf.default.accept_source_route = 0

kernel.shmmax = 68719476736

kernel.shmall = 4294967296

fs.file-max = 65536

继续改动/etc/security/limits.conf文件:

[root@CELL ~]# vi /etc/security/limits.conf

最后加入两行:

* soft nofile 65536

* hard nofile 65536

改动完后用celladmin用户又一次登录。查看限制:
