创建本地源,使用yum install

sure_dandan — Thu, 20 Oct 2011 01:22:00 GMT

这几天安装oracle,检查包的时候,发现一些包没有装上,使用rpm来装的时候,又发现包的依耐性很重,所以就搭建一个本地的源,使用yum install来安装.

1.挂载安装介质

mount /dev/cdrom /mnt/cdrom

如果是实体机:
mount -o loop 镜像所在目录挂载点

2.vi /etc/yum.repos.d/server.repo

[dange]                                        #随意填
name=red hat                                   #随意填
baseurl=file:///mnt/cdrom/RedHat/Server        #光盘挂载，Server目录所在路径
enable=1                                       #yum开关
gpgcheck=1                                     #是否检查密钥
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release      #密钥所在地

3.如果安装软件包提示没有key的话导入key

cd /mnt/cdrom
rpm --import  RPM-GPG-KEY-redhat-release   //安装验证文件,导入key
yum list                                   //列出仓库中的所有软件,查看yum是否搭建成功
yum clean  all                             //清空yum仓库

4.OK,可以直接使用yum install了

Mount Options for Oracle files when used with NAS devices [ID 359515.1]

  Purpose
  Scope and Application
  Mount Options for Oracle files when used with NAS devices
     RAC
      Single Instance
  References

Applies to:

Oracle Server - Enterprise Edition - Version: 10.1.0.2 to 11.2.0.2 - Release: 10.1 to 11.2
Information in this document applies to any platform.
Oracle Clusterware, Oracle Real Application Clusters, NAS

Purpose

The purpose of this bulletin is to document the options with which the NAS systems should be mounted. This note does not cover the new dNFS feature that was introduced in 11g.

Scope and Application

This document is relevant to all environments using Oracle Clusterware & RAC.

Mount Options for Oracle files when used with NAS devices

RAC

In the table below

Binaries is the shared mount points where the Oracle Home and CRS_HOME is installed.
Datafiles includes Online Logs, Controlfile and Datafiles
nfsvers and vers are identical on those OS platforms that has nfsvers. The ver option is an alternative to the nfsvers option. It is included for compatibility with other operating systems
Please note that the mount options on each of the following cells are applicable only to those type of files listed in the column heading.
For RMAN backup sets, image copies, and Data Pump dump files, the "NOAC" mount option should not be specified - that is because RMAN and Data Pump do not check this option and specifying this can adversely affect performance.

* NFS mount option “forcedirectio” is required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)
** AIX is only supported with NAS on AIX 5.3 TL04 and higher with Oracle 10.2.0.1 and later (NetApp)
*** NAS devices are only supported with HPUX 11.23 or higher ONLY
**** As per BUG 11812928, the 'intr' & 'nointr' are deprecated in OEL 5.6 kernels and up including Oracle Linux 6. It is harmless to still include it, but the "NFS: ignoring mount option: nointr" will appears. This message can be ingnored.

# These mount options are for Linux kernels 2.6 and above for older kernels please check Note 279393.1

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4. This bug is fixed and included in 10.2.0.4 patchset.

用ntpd配置节点间的时间同步

sure_dandan — Sun, 16 Oct 2011 15:14:00 GMT

1.检查时区：

检查/etc/sysconfig/clock设置：
ZONE="Asia/Shanghai"(Linux会拷贝/usr/share/zoneinfo/Asia/Shanghai 到/etc/locatime作为本地时区,如果我们需要改变时区,那么只需要修改/etc/sysconfig/clock,并且将对应的/usr/share/zoneinfo/Asia的时区文件拷贝成/etc/localtime即可)
UTC=false
ARC=false

2.安装NTP包：

rpm -ivh ntp-xxxxxx.rpm
或者:
yum install ntp

3.编辑/etc/ntp.conf文件：

服务端:
server 127.127.1.0
fudge 127.127.1.0 stratum 11
driftfile /var/lib/ntp/drift
broadcastdelay 0.008
客户端:
server 192.168.0.11 prefer #192.168.0.11为服务端的ip地址
driftfile /var/lib/ntp/drift
broadcastdelay 0.008

4.重启ntp服务：

service ntpd restart

5.等待5分钟,测试客户端更新时间:

ntpdate 192.168.0.11
Oct 16 21:09:28 ntpdate[8316]: step time server 192.168.0.11 offset -1791.709393 sec

6.在客户端将更新时间加入crontab:

(1).cp /usr/sbin/ntpdate /usr/bin/
(2).crontab –e
加入
*/1 * * * * /usr/sbin/ntpdate 192.168.0.11 ; hwclock –w

7.加入自启动

chkconfig ntpd on

xmanager的使用

sure_dandan — Thu, 13 Oct 2011 17:35:00 GMT

当服务器没有装图形化界面的时候,如不能使用xhost之类的命令,就不能使用vnc了,那这个时候可以使用xmanager来代替

1.网上可以下载一个xmanager企业版,下载完后打开Xbrowser,在help-->about Xbrowser中输入注册码

2.在服务器端
DISPLAY=192.168.X.X:0.0
export DISPLAY
echo $DISPLAY

3.使用xmanager的xshell来打开图形化界面.(有可能会提醒运行一个rootpre之类的脚本)

redhat5配置裸设备

sure_dandan — Thu, 13 Oct 2011 17:28:00 GMT

在Redhat5之前通过/etc/sysconfig/rawdevices配置raw的控制文件,通过/etc/init.d/rawdevices来管理raw设备的启动和关闭.

在Redhat5之后,需要编辑/etc/udev/rules.d/60-raw.rules 这个文件.

1.假设已经把一个硬盘新建了几个区

fdisk -l /dev/sdc

/dev/sdc1

/dev/sdc2

/dev/sdc3

2.修改/etc/udev/rules.d/60-raw.rules

添加:

ACTION=="add", KERNEL=="sdc1",RUN+="/bin/raw /dev/raw/raw1 %N"

ACTION=="add", KERNEL=="sdc2",RUN+="/bin/raw /dev/raw/raw2 %N"

ACTION=="add", KERNEL=="sdc3",RUN+="/bin/raw /dev/raw/raw3 %N"

假设这个设备是给oracle用的,那再加上权限

KERNEL=="raw[1-3]*", NAME="raw/%k" OWNER="oracle" GROUP="oinstall", MODE="0660"

3.修改完之后重启服务

start_udev

4.查看

raw -qa 或者 ls -lrt /dev/raw/

5.取消映射

raw /dev/raw/rawX 0 0

关闭Sendmail服务

sure_dandan — Mon, 10 Oct 2011 03:36:00 GMT

在虚拟机上起动系统的时候,每次都发现Sendmail服务很费时间,决定将其关闭了,反正也没怎么用.
1.关闭sendmail服务

[root@node1 ~]# /etc/rc.d/init.d/sendmail stop
Shutting down sm-client: [ OK ]
Shutting down sendmail: [ OK ]

2.关闭sendmail自启动

[root@node1 ~]# chkconfig sendmail off

3.确认sendmail自启动已被关闭

[root@node1 ~]# chkconfig --list sendmail

sendmail 0:off 1:off 2:off 3:off 4:off 5:off 6:off
