一 : CentOS6.3安装VBoxAdditions
CentOS6.3安装VBoxAdditions
CentOS6.3是安装在VirtualBox虚拟机上,安装好以后最好再将VBoxAdditions增强功能装上,
主要目的是能够在虚拟机和宿主机之间能够共享文件。

1. 更新内核。CentOS 6.3对应的kernel默认为2.6.32-279.el6.i686:
# uname -r
2.6.32-279.el6.i686
安装增强功能需要kernel-devel包,必须保证kernel-devel和kernel版本的一致。查看软件源中
kernel-devel的版本:
]# yum info kernel-devel
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirrors.163.com
* extras: mirrors.163.com
* updates: mirrors.163.com
Available Packages
Name : kernel-devel

Version : 2.6.32
Release : 279.19.1.el6
Size : 7.6 M
Repo : updates
Summary : Development package for building kernel modules to match the

当前的kernel-devel版本是2.6.32-279.19.1.e16。因此,必须升级kernel:
# yum update kernel
升级完后必须重启系统,新的kernel才能被使用。 www.2cto.com
2. 安装kernel-devel和gcc。
# yum install kernel-devel gcc gcc-c++
3. 安装增强功能。进入增强功能光盘根目录,执行Linux下的安装命令:
# ./VBoxLinuxAdditions.run

二 : 主题:Centos6.4安装JDK
1.先看看OpenJDK的安装包
$ rpm -qa |grep java
tzdata-java-2013b-1.el6.noarch
java-1.6.0-openjdk-1.6.0.0-1.61.1.11.11.el6_4.x86_64
java-1.7.0-openjdk-1.7.0.19-2.3.9.1.el6_4.x86_64
2.检查OpenJDK版本
$ java -version
java version "1.7.0_19"
OpenJDK Runtime Environment (rhel-2.3.9.1.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
3.卸载Openjdk
用root用户登录终端
$ su root
密码:
$ rpm -e --nodeps java-1.7.0-openjdk-1.7.0.19-2.3.9.1.el6_4.x86_64
$ rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.61.1.11.11.el6_4.x86_64
$ rpm -e --nodeps tzdata-java-2013b-1.el6.noarch
4安装jdk-7u17-linux-x64.rpm
下载地址:http://pan.baidu.com/share/link?shareid=397488&uk=638583574
$ cd /jdk1.7所在目录
$ rpm -ivh jdk-7u17-linux-x64.rpm
Preparing... ########################################### [100%]

localedata.jar...
Error: Could not open input file: /usr/java/jdk1.7.0_17/jre/lib/ext/localedata.pack
以上那些错误可以忽略,不影响jdk到安装和使用
5.配置环境变量
$vi /etc/profile
输入o,在最后加入以下内容:
JAVA_HOME=/usr/java/jdk1.7.0_17
JRE_HOME=/usr/java/jdk1.7.0_17/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export JAVA_HOME JRE_HOME PATH CLASSPATH
使环境变量立即生效
$source /etc/profile
6.测试安装是否成功
依次输入java,java -version,javac,看到输出信息即可,例如
[root@chenpc-cent tools]# java -version
java version "1.7.0_17"
Java(TM) SE Runtime Environment (build 1.7.0_17-b02)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)主题:Centos6.4安装JDK
三 : centos6.3安装smokeping
由于公司需要监控机房的网络质量无奈只能安装smokeping,鉴于网上的教程大多都是老版本的,所以今天我就讲诉一下我在centos上安装新版本的过程,有些得不好的地方还请大家多多原谅。[www.61k.com)以下所有安装包请到这里下载。
1.先关闭selinux和清空iptables
vim /etc/selinux/config
SELINUX=disabled
iptables -F
2.更改国内比较快的yum源,我修改为ustc的,个人感觉他比较快。
cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.bak
vim CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead.

ok,准备工作已做好,下面我们开始安装了。[www.61k.com]
3.安装环境所需要的yum包
yum -yinstall libxml2-devel libpng-devel glib pango pango-devel
freetypefreetype-devel fontconfig cairo cairo-devel libart_lgpl libart_lgpl-devel perl perl-Net-Telnet perl-Net-DNSperl-LDAP perl-libwww-perl perl-RadiusPerl perl-IO-Socket-SSL perl-Socket6perl-CGI-SpeedyCGI rrdtool-perl
4.安装rrdtool
wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.7.tar.gz
tar zxvf rrdtool-1.4.7.tar.gz
cd rrdtool-1.4.7
./configure --prefix=/usr/local/rrdtool
make && make install
5.安装smokeping依赖的软件
【cgilib】
tar zxvf cgilib-0.5.tar.gz
cd cgilib-0.5
make
cp libcgi.a /usr/local/lib
cp cgi.h /usr/include
ping6 centos6.3安装smokeping
【fping-2.4b2_to】
tar zxvf fping.tar.gz
cd fping-2.4b2_to
./configure
make
make check
make install
whereis fping
fping: /usr/local/sbin/fping
【echoping】
tar zxvf echoping-6.0.0.tar.gz
cd echoping-6.0.0
./configure
make
make test
遇到测试不成功等信息就 ctrl+c 回到命令行;
make install
whereis echoping
echoping: /usr/local/bin/echoping/usr/local/lib/echoping
安装echoping是有可能会报错,这是因为缺少popt支持,我们需要安装popt
要安装popt还需要gettext的支持,首先安装gettext
tar zxvf gettext-0.18.tar.gz
cd gettext-0.18
./configure
make && make install
cd ..
tar zxvf popt-1.10.4.tar.gz
cd popt-1.10.4
./configure
make && make install
cd .. cd echoping-6.0.0
./configure
make && make install
6.安装smokeping
wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.8.tar.gz
tar zxvf smokeping-2.6.8.tar.gz
cd smokeping-2.6.8
./configure –prefix=/usr/local/smokeping
编译的时候会报错提示缺少很多的扩展程序,这时候我们只需要执行一个安装脚本就好了 ./setup/build-perl-modules.sh /usr/local/smokeping/thirdparty
等他安装完再继续编译安装
./configure –prefix=/usr/local/smokeping
ping6 centos6.3安装smokeping
gmake install
安装完毕,下面修改配置文件。www.niubb.net
进入bin目录,修改smokeping文件
#vim smokeping
第八行: use lib qw(); # PERL5LIB
修改为: use lib qw(/usr/local/rrdtool/lib/perl);
进入htdocs目录
# mv smokeping.fcgi.dist smokeping.fcgi
进入etc目录
cp config.dist config
修改config文件
#vim config

创建存放数据文件的目录
mkdir c/usr/local/smokeping/data /usr/local/smokeping/var /usr/local/smokeping/cache
修改smokeping的目录为apache运行用户的属主、组
chown -R daemon.daemon smokeping/
chmod 600 /usr/local/smokeping/etc/smokeping_secrets.dist
chmod –R 777 /usr/local/smokeping/cache /usr/local/smokeping/data /usr/local/smokeping/var
创建smokeping的log文件
touch /var/log/smokeping.log
chown daemon.daemon /var/log/smokeping.log
启动smokeping
perl /usr/local/smokeping/bin/smokeping --logfile=/var/log/smokeping.log 建立smokeping启动脚本,方便启动
vim /etc/init.d/smokeping
添加为以下内容:

# chmod 755 /etc/init.d/smokeping
设置开机启动smokeping
Chkconfigure –level 35 smokeping on
配置apache
#vim /etc/httpd/conf/httpd.conf
最后加入

四 : U盘安装centos6.5教程(两种实现方法)
从centOS6.5开始直接把iso文件写入u盘就行了。
下载地址为:
windows平台:
1.用UltraISO打开iso(如:CentOS-6.5-x86_64-bin-DVD1.iso)
2.然后点“启动”->"写入硬盘映像",硬盘驱动器是你的u盘,映像文件安装光盘iso,写入方式是USB-HDD+,点击“写入”按钮。完成后安装u盘就做好了。
linux平台:
用 dd命令将iso文件写入u盘即可。dd if=iso文件 of=u盘。(如:dd if=/CentOS-6.5-x86_64-bin-DVD1.iso of=/dev/sdb1)
注:dd命令运行后不显示复制状态,要查看复制状态可以再打开一个终端,输入“while killall -USR1 dd; do sleep 5; done”查看复制状态。
这种方法64位,32位通吃。我安装的就是64位。
注意:只有从CentOS6.5开始才能用这种方法,6.4及以下版本还得用老方法。
可能有许多人已经知道这个方法了,但是网上很多教程还都是老方法。我写出来就是想传播一下,让新手少走弯路。
补充方法:
U盘安装centos6.5和安装centos6.3没啥本质区别
所需工具:
一、UltraISO(用来制作 U 盘启动)
二、CentOS 6.5 位系统镜像(建议下载bin版镜像,minimal也行)
三、U 盘一只
要求:U 盘容量 8G
四、vesamenu.c32 文件——用来替换 CentOS 6.5 默认文件(附件中我提供了哦,解压缩后替换原来的文件)这里我没用到
安装步骤:
一、制作 U 盘启动引导盘
1、电脑插上 U 盘,打开 UltraISO 软件,文件---打开,选择你下载好的CentOS-6.3-i386-bin-DVD1.iso 文件,点启动--写入硬盘镜像,在硬盘驱动器里面选择你的 U 盘(看清楚,千万别选错),写入方式默认为:USB-HDD+,然后点格式化。格式化完成后,关闭对话框,然后再点写入,等几分钟,完成后,点返回,然后关闭 UltraISO。
2、打开 U 盘根目录下面的 syslinux 文件夹,用附件中的 vesamenu.c32 替换里面原有
的文件。
3、删除 U 盘根目录下面的 Packages 文件夹(不删除也可以,如果你U盘空间足够大)
4、把下载好的系统镜像 CentOS-6.3-i386-bin-DVD1.iso和CentOS-6.3-i386-bin-DVD2.iso 复制到 U 盘根目录下面。(不用改名字,安装时会自动识别)
至此,U 盘启动盘制作完成,然后退出 U 盘,这个 U 盘现在已经可以用来安装 CentOS 6.3 了。
二、安装 CentOS 6.3
1、开机设置 U 盘第一启动,重启之后会出来安装界面:
默认选择第一项,回车。
2、出现安装过程中使用的语言界面:
选择 Chinese(Simplified),简体中文,然后回车
3、出现语言确认界面直接回车
4、下面出现键盘模式选择界面:
选择键盘模式,默认
5、定位在 Hard drive 上, directory holding image此项不用填写,系统会自动去填写。(其实这项是搜索image目录下的install.img文件)选择 OK,按回车
6、这里的/dev/sdb4 代表你的 U 盘分区,我们前面已经把系统镜像拷贝到 U 盘根目录下面了,这里系统会自动识别
7、直接点 OK,会出现安装界面:
点击下一步
8、选择驱动器:
选第一项
9、设置计算机名:
可以根据自己喜好填写
10、设置时区:
默认即可
11、设置root密码(注意:如果你使用的密码过于简单,系统会自动提示,这里选择“仍然使用”
12、为centos建立分区
选择最后一项,自定义分区
13、注意:这里可以看到磁盘信息,切忌要确定在自己所要分区的磁盘上分区,否则其他磁盘会被格式化。
14、点创建,选择标准分区,点确定
(1)创建swap分区
文件系统类型:选择 swap
允许的驱动器:只勾选自己电脑磁盘,把u盘取消掉
大小:2048
其它大小选项:固定大小
(2)创建boot分区
挂载点: /boot
文件系统类型:ext4
允许的驱动器:只勾选自己电脑磁盘,把u盘取消掉
大小:100MB
其它大小选项:固定大小
(3)创建根分区
挂载点: /
文件系统类型:ext4
允许的驱动器:只勾选自己电脑磁盘,把u盘取消掉
大小:默认
其它大小选项:使用全部可用空间
点击下一步
选择第二项,将修改写入磁盘
注意:分区之前,自己先要规划好怎么分区?
特别说明:用于正式生产的服务器,切记必须把数据盘单独分区,防止系统出问题时,保证
数据的完整性。比如可以再划分一个/data 专门用来存放数据。
15、点更改设备(千万注意引导程序安装的地方,引导写到电脑磁盘上的MBR,不是U盘的,千万注意)
点 BIOS 驱动器顺序
第一 BIOS 驱动器:选择 本地磁盘驱动器
第二 BIOS 驱动器:选择 U 盘驱动器
点确定
说明:这一步至关重要,如果按照默认方式安装,会把系统启动引导安装到 U 盘里面,这也
就是很多网友安装完系统之后,只要把 U 盘拔了,系统就启动不了,插上 U 盘系统又能正常
启动的原因了!
16、默认是第三个,这里选择第一个,桌面安装,想用来开发的朋友也可以选择最后一项。
如果有想特意安装些特别的软件的网友,可以注意,在此处添加安装。
下一步,直到出现安装界面。
17、安装完成后,点重新引导
18、重新启动,把U盘拔出,电脑自动引导到centos系统
19、点击前进
20、选择第一项,同意许可协议,前进
21、这里是创建普通账号,可以不用创建,前进
22、设置时间,默认
23、完成
,进入登录界面
点“其他”
用户名输入:root
输入你 root 账号的密码
点“关闭”
备注:如果不替换 vesamenu.c32 文件,用 U 盘启动后会卡在下面的界面:Press the <Enter>
key to begin the installation process
原因:U 盘根目录下面的 syslinuxsyslinux.cfg 文件里面第一行引用到了
vesamenu.c32 这个文件,而在 CentOS 6.3 系统里面,这个文件是有 bug的,所以要用 CentOS 6.0 系统的这个文件来替换。
(也就是我附件中提供的这个文件)这里我没用到vesamenu.c32。
