# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#
#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.

mysql 遠程訪問的設置

VNC，全稱為Virtual Network Computing，它是一個桌面共享系統。它的功能，類似于Windows中的遠程桌面功能。VNC使用了RFB(Remote FrameBuffer，遠程幀緩沖）協議來實現遠程控制另外一臺計算機。它把鍵盤、鼠標動作發送到遠程計算機，并把遠程計算機的屏幕發回到本地。

VNC技術與平臺無關，VNC VIEwer可以和VNC Server在不同的操作系統上。VNC幾乎支持所有的操作系統，也支持Java，甚至可以通過支持Java的瀏覽器來訪問VNC Server。多個VNC客戶端可以同時連接到一個VNC Server上。

VNC最初由AT&T開發的，它的源代碼是開源的。

在CentOs 4.3上配置VNC服務很簡單(這里假定你的計算機上已經安裝了VNC軟件)

首先需要配置VNC密碼，密碼在使用客戶端連接服務器時使用。

注意：VNC密碼保存在用戶的主目錄中，每個用戶都可以設置自己的密碼。因此，請使用你的用戶名(盡量不要使用root)運行下列命令：

vncpasswd

然后輸入密碼。

接下來就可以啟動VNC server了。在啟動VNC server時，需要為你的server指定一個display參數。你可以把display理解為一個桌面，每個用戶都可以有自己的桌面。VNC客戶端在連接時，可以指定連接到哪個桌面上。在系統中，display號不能重復，也就是說，如果有用戶已經建立了名為“:1”的display，另外一個用戶就不能再使用“:1”了，他可以使用“:2”。

啟動VNC server的命令是：

vncserver ＜display＞

例如，

vncserver :1

最后，需要配置一下防火墻，允許VNC客戶端連接VNC server。VNC server監聽的端口從5900開始，display :1的監聽5901，display :2監聽5902，以此類推。CentOs的防火墻缺省是不允許連接這些端口的，所以需要使用下面的步驟打開防火墻（需要root權限)：

vi /etc/sysconfig/iptables

找到下面的語句：

-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited

在此行之前，加上下面的內容：

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5900:5903 -j ACCEPT

這句話的含義是，允許其它機器訪問本機的5900到5903端口，這樣，display:1, display:2, display:3的用戶就可以連接到本機。

然后使用root身份重新啟動防火墻：

/sbin/service iptables restart

好了，現在就可以運行客戶端軟件，連接到VNC server上了。

VNC客戶端軟件很多，在Linux下有vncviewer，KDE還提供了一個krdc（它的菜單項就是”Remote Desktop Connection"，遠程桌面連接）。

在window也有不少vnc客戶端，你可以到http://www.realvnc.com/去下載一個，安裝就可以用了。

假設VNC server的IP地址是192.168.1.1，display是:1。在VNC viewer的server欄中輸入：“192.168.1.1:1”，然后連接。OK，你可以看到自己的桌面了。以后不管你什么時候關閉自己的本地PC機都不怕了，只要server不關機，你只要連接到VNC server，你就可以看到你前一天關閉本地PC機時的桌面還保持著原樣。

不過...這個桌面怎么這么丑？！

原來vncserver默認使用的窗口管理器是twm，這是一個很簡陋的窗口管理器，你可以把你的桌面改成GNOME或KDE。

方法是，進入你自己的home目錄，然后編輯這個文件：.vnc/xstartup，下面是這個文件的內容：

#!/bin/sh

# Uncomment the following two lines for normal desktop:

#unset SESSION_MANAGER

#exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

xsetroot -solid grey

vncconfig -iconic &

xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

#twm &

gnome-session &

你可以把像上面這樣把"twm &"這一行注釋掉，然后在下面加入一行"gnome-session &"，或者是"startkde &"，分別啟動GNOME桌面和KDE桌面。

如果server重啟了，那你就需要重新運行一次vncserver命令來啟動VNC server，這很麻煩。有沒有更好的方法呢？

有！我們可以把VNC server啟動成后臺服務。執行如下步驟：

首先要允許VNC server在系統啟動過程中被啟動。這可以通過“系統設置-->服務器設置-->服務”菜單來配置，把vncserver一項選上就可以了。

如果使用命令行的話，以root身份運行以下兩條命令：

cd /etc/rc5.d

mv K35vncserver S35vncserver

然后編輯/etc/sysconfig/vncservers，以下是文件內容：

																# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the line below to start a VNC server on display :1
# as my 'myusername' (adjust this to your own).  You will also
# need to set a VNC passWord; run 'man vncpasswd' to see how
# to do that.
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted!  For a secure way of using VNC, see
# <URL:http://www.uk.research.att.com/vnc/sshvnc.HTML>.
VNCSERVERS="1:user1 2:user2 3:user3"
VNCSERVERARGS[1]="-geometry 1024x768"
VNCSERVERARGS[2]="-geometry 1024x768"
VNCSERVERARGS[3]="-geometry 800x600"
														

解釋一下這個文件：

VNCSERVERS這一行是配置在系統啟動時啟動幾個VNC server，上面的例子里運行了三個VNC server，其中user1在display :1，user2在display :2，user3在display :3。

VNCSERVERARGS這三行，分別為VNC server 1, 2, 3配置啟動參數，上面的例子里對user1和user2使用屏幕分辨率1024x768，對user3使用800x600。

其它支持的參數請使用“man vncserver”命令查詢。

編輯好這個文件后，保存，然后以root身份運行：

/sbin/service vncserver start

這樣user1, user2, user3的vncserver就啟動了。

以后每次系統重啟時，都會自動啟動這三個用戶的vncserver。

注意：上面三個用戶必須已經使用vncpasswd命令設置過vnc密碼，不然他的vncserver啟動會失敗

Linux 9 安裝過程。
首先在bios中的啟動順序改為從cd-rom 啟動，同時修改相關的io-device。設置為auto
格式化選擇自動分區。
安裝過程中版本選擇選擇服務器版本。
4.root的用戶密碼默認為：123456
完成安裝。

二..jdk安裝
1.到java官方網站去下載linux版本的jdk 1.5（prm）
2.運行相應的jdk rpm 安裝文件,自動安裝到/usr/java/jdk1.5.0_14?? 目錄下面
3設置類路徑:
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC
export JAVA_HOME=/usr/java/jdk1.5.0_14
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin
在 /etc/profile? 添加上面的代碼即可
重起計算機運行javac即可完成測試: 如果出現javac相關的信息則說明安裝成功。
二。openfire的安裝以及部署
到openfire官方網站上去下載最新的openfire
關于openfire? 的部署以及啟動.自動安裝到opt/openfire目錄下面 相應的啟動文件為
/opt/openfire/bin/openfire.sh
?將oracle9驅動classses12.jar復制到 /opt/openfire/lib目錄下面,同時還需要修改配置文件/opt/openfire/conf/openfire.xml??

?如果是oracle則需要將classses12.jar復制到 /opt/openfire/lib目錄下面,同時還需要修改配置文

件/opt/openfire/conf/openfire.xml
<?xml version="1.0" encoding="UTF-8"?>

??? Oracle9i 在Linux9上的安裝過程

添加安裝過程中需要用到的用戶和組，這當中會用到二個用戶一個是root，一個是oracle
#groupadd oinstall
#groupadd dba
#useradd –g oinstall –G dba oracle
#passwd oracle
?(二）新建安裝目錄
#mkdir –p /data/oracle9/product/9.2.0
#chown –R oracle.oinstall /data/oracle9
#mkdir /var/opt/oracle
#chown oracle.dba /var/opt/oracle
#chmod 755 /var/opt/oracle
（三）為了一開機系統就能自動幫你設好這些參數，
也可改動 /etc/sysctl.conf 這個文件，加入以下的語句：
kernel.shmmax = 8589934590
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

注意：如果你的共享內存不夠大的話，在安裝的過程中會提示ORA-27123錯誤，到時候你只要把/proc/sys/kernel/shmmax的值調大就

可以了到于多大就看你的了

(六） oracle對文件的要求：編輯文件：
/etc/security/limits.conf 加入以下語句：
oracle 　　　soft 　　　nofile 　　 65536
oracle 　　　hard 　　 nofile　　　65536
oracle 　　　soft 　　　nproc 　　 16384
oracle 　　　hard 　　 nproc 　　 16384

設置oracle的環境
vi ~/.bash_profile
export LD_ASSUME_KERNEL=2.4.10
export ORACLE_BASE=/data/oracle9
export ORACLE_HOME=/data/oracle9/product/9.2.0
export ORACLE_SID=ora9i
export ORACLE_TERM=xterm
#export NLS_LANG=AMERICAN
export ORACLE_OWNER=oracle
export THREADS_FLAG=native
#export LANG=en_US
export ORA_NLS33=$OROCLE_HOME/ocommon/nls/admin/data
export LD_LIBRARY_PAHT=/data/oracle9/product/9.2.0/lib:/lib:/usr /lib:/usr/local/lib
export PAHT=/data/oracle9/product/9.2.0/bin:$PATH
export PATH=$PATH:$ORACLE_HOME/bin

#su – oracle
$ vi ~/.bash_profile export LD_ASSUME_KERNEL=2.4.1
#export DISPLAY=”192.168.9.205:0.0” (127.0.0.1:0.0)
export ORACLE_BASE=/data/oracle9 export ORACLE_HOME=/data/oracle9/product/9.2.0
export ORACLE_SID=ora9i (數據庫全局變量名)
export ORACLE_TERM=xterm (xterm窗口模式 vt100 終端調試模式)
export NLS_LANG=AMERICAN (設置語言AMERICAN英文)
export ORACLE_OWNER=oracle
export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data
export THREADS_FLAG=native
export LD_LIBRARY_PATH=/data/oracle9/product/9.2.0/lib:/lib:/usr /lib:/usr/local/lib export

PATH=/data/oracle9/product/9.2/bin:$PATH export PATH=$PATH:$ORACLE_HOME/bin

然后注銷再重新登錄就可以,oracle 的環境就應該生效了 （要用英文環境）
安裝oracle ：
ship_9204_linux_disk1.cpio.gz
ship_9204_linux_disk2.cpio.gz
ship_9204_linux_disk3.cpio.gz
用zcat ship_9204_linux_disk1.cpio.gz|cpio -idmv
zcat ship_9204_linux_disk2.cpio.gz|cpio -idmv
zcat ship_9204_linux_disk3.cpio.gz|cpio -idmv
生成三個文件夾Disk1，Disk2，Disk3；
你也可以用（我用的是這個）
cpio -idmv < ship_9204_linux_disk1.cpio
cpio -idmv < ship_9204_linux_disk2.cpio
cpio -idmv < ship_9204_linux_disk3.cpio
在當前目錄上會產生三個目錄：
Disk1,Disk2,Disk3
#cd Disk1
#./runInstaller 出現圖形安裝界面。
按照提示完成安裝即可。
安裝過程中可能遇到的問題
1.遇到亂碼時首先運行 export LANG=en_US
2.創見一個指向的鏈接:
ln -s /data/oracle9/product/9.2.0/oracle.swd.jre/bin/i386/native_threads/java

/data/oracle9/product/9.2.0/oracle.swd.jre/bin/i386/native_threads/jre
配置監聽器服務命名還有目錄服務 net config assistent
?/data/oracle9/product/9.2.0/bin/netca
啟動oracle監聽器.
/data/oracle9/product/9.2.0/bin/lsnrctl start TLINK
配置啟動oracle服務器
?/data/oracle9/product/9.2.0/bin/dbca
在gui模式下啟動oracle

linux 常見命令:
neat? =====redhat-config-network 配置網絡
redhat-config-users 配置用戶
?rpm -Uvv openfire.rpm --force?? 強制更新軟件
rpm -ql package 列出該軟件的所有文件所在的目錄???? | less? 分頁顯示結果
rpm -qa 列出所有已安裝的包
rpm -qi package 列出包信息
?/etc/rc.d/init.d/httpd start
啟動 apache：
/etc/rc.d/init.d/httpd stop
關閉apache
? 關于ssh 因為在linux下是內置的服務，所以只要啟動服務即可。讓在window下用ssh的客戶端即可進行操作
