篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了OracleExadata虚拟机配置相关的知识，希望对你有一定的参考价值。
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：
[[email protected] ~]# 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
default=1 原本为0 改为1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
。。
。。
略。
。
。
重新启动系统：
[[email protected] ~]# reboot
hosts文件配置例如以下：
[[email protected] ~]# 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：
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.90.255
HWADDR=00:0C:29:3D:9A:03
IPADDR=192.168.90.151
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
[[email protected] ~]# vi /etc/yum.repos.d/public-yum-el5.repo
[oel5]
name = Enterprise Linux 5.6 DVD
baseurl=file:///mnt/Server/
gpgcheck=0
enabled=1
[[email protected] ~]# mount /dev/cdrom /mnt
mount: block device /dev/cdrom is write-protected, mounting read-only
[[email protected] ~]# yum install oracle-validated
Loaded plugins: rhnplugin, security
This system is not registered with ULN.
ULN support will be disabled.

建立文件夹：
[[email protected] ~]# mkdir -p /var/log/oracle
[[email protected] ~]# chmod -R 775 /var/log/oracle
上传介质后解压：
[[email protected] soft]# tar -pxvf cellImageMaker_11.2.3.3.1_LINUX.X64_140708-1.x86_64.tar

Installation SUCCESSFUL.
Starting RS and MS... as user celladmin
Done. Please Login as user celladmin and create cell to startup CELLSRV to complete cell configuration.
If this is a manual installation, please stop and restart ExaWatcher to pick up newly installed binaries.
You can run "/opt/oracle.ExaWatcher/ExaWatcher.sh --stop" and then "/opt/oracle.ExaWatcher/ExaWatcher.sh --fromconf" to stop and restart ExaWatcher.
Logout and then re-login to use the new cell environment.

CELL-02018: Internal error detected: Not enough open file descriptors.
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：
Number of open file descriptors per process is 1024
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：
[[email protected] ~]# vi /etc/sysctl.conf
最后一行加入：
fs.file-max = 65536
生效一下：
[[email protected] ~]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 2
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
fs.file-max = 65536
继续改动/etc/security/limits.conf文件：
[[email protected] ~]# 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：
[[email protected] ~]$ ulimit -a
