Linux下虛擬主機配置

發(fā)布時間: 2012/8/5 13:27:12

　目標，在Linux進行apache2.2版本和tomcat6版本的虛擬主機配置。有些時候apache2.2是不能將請求轉發(fā)給tomcat的（例如直接處理靜態(tài)頁面的顯示），所以我們直接用ajp代理之類的簡單策略就沒有辦法區(qū)分動態(tài)項目和靜態(tài)項目處理方式了。在這個方面，tomcat早有準備，推出了tomcat-connectors進行了支持。
　　前期安裝：
　　1、apache已經(jīng)完全安裝到了/usr/local/apache2.2目錄下了，web服務端口是80。啟動后是apache的it works！提示
　　2、tomcat6已經(jīng)安裝到了/usr/local/tomcat6目錄下了。8009端口開發(fā)，web服務端口是8080。啟動后是tomcat的默認頁。
　　我在tomcat6的webapps下已經(jīng)部署了兩個jsp項目MicTrader 和MicSeller。通過
　　http://ip:8080/MicTrader和http://ip:8080/MicSeller能訪問
　　3、jdk已經(jīng)安裝了，并且上邊的兩個服務已經(jīng)可用了
　　4、linux的RedHat4版本，相關編譯包已經(jīng)ok了
　　下載：
　　1、connector包：Apache Tomcat Connectors (mod_jk) 1.2.30 for Linux i586
　　命令：wget http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.30/i586/mod_jk-1.2.30-httpd-2.2.X.so
　　注意：http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.30/i586/這個頁面有介紹當前版本支持的linux版本以及apache和tomcat的版本，千萬別下載錯了版本，否則linux的系統(tǒng)不支持訪問
　　2、下載后的so文件名：mod_jk-1.2.30-httpd-2.2.X.so
　　將文件拷貝并重命名到：/usr/local/apache2.2/modules/mod_jk.so
　　給文件賦予系統(tǒng)讀寫權限：cd /usr/local/apache2.2/modules
　　chmod 777 mod_jk.so
　　3、進行相關文件的配置(操作前請備份一份)
　　（1）、配置httpd.conf。注意內部標注add by kongqz的地方。都是我加上去的。主要是進行了mod_jk.so模塊加載，以及虛擬主機的配置兩個配置工作
　　#
　　# This is the main Apache HTTP server configuration file. It contains the
　　# configuration directives that give the server its instructions.
　　# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
　　# In particular, see
　　# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
　　# for a discussion of each configuration directive.
　　#
　　# Do NOT simply read the instructions in here without understanding
　　# what they do. They're here only as hints or reminders. If you are unsure
　　# consult the online docs. You have been warned.
　　#
　　# Configuration and logfile names: If the filenames you specify for many
　　# of the server's control files begin with "/" (or "drive:/" for Win32), the
　　# server will use that explicit path. If the filenames do *not* begin
　　# with "/", the value of ServerRoot is prepended -- so "logs/foo_log"
　　# with ServerRoot set to "/usr/local/apache2.2" will be interpreted by the
　　# server as "/usr/local/apache2.2/logs/foo_log".
　　#
　　# ServerRoot: The top of the directory tree under which the server's
　　# configuration, error, and log files are kept.
　　#
　　# Do not add a slash at the end of the directory path. If you point
　　# ServerRoot at a non-local disk, be sure to point the LockFile directive
　　# at a local disk. If you wish to share the same ServerRoot for multiple
　　# httpd daemons, you will need to change at least LockFile and PidFile.
　　#
　　ServerRoot "/usr/local/apache2.2"
　　#
　　# Listen: Allows you to bind Apache to specific IP addresses and/or
　　# ports, instead of the default. See also the <VirtualHost>
　　# directive.
　　#
　　# Change this to Listen on specific IP addresses as shown below to
　　# prevent Apache from glomming onto all bound IP addresses.
　　#
　　#Listen 12.34.56.78:80
　　Listen 80

　　# Dynamic Shared Object (DSO) Support
　　#
　　# To be able to use the functionality of a module which was built as a DSO you
　　# have to place corresponding `LoadModule' lines at this location so the
　　# directives contained in it are actually available _before_ they are used.

　　# to be loaded here.

　　# Redirect: Allows you to tell clients about documents that used to

　　# will make a new request for the document at its new location.
　　# Example:
　　# Redirect permanent /foo http://www.example.com/bar
　　#
　　# Alias: Maps web paths into filesystem paths and is used to
　　# access content that does not live under the DocumentRoot.
　　# Example:
　　# Alias /webpath /full/filesystem/path
　　#
　　# If you include a trailing / on /webpath then the server will
　　# require it to be present in the URL. You will also likely
　　# need to provide a <Directory> section to allow access to
　　# the filesystem path.
　　#
　　# ScriptAlias: This controls which directories contain server scripts.
　　# ScriptAliases are essentially the same as Aliases, except that
　　# documents in the target directory are treated as applications and
　　# run by the server when requested rather than as documents sent to the

　　# If your server contains mostly text or HTML documents, "text/plain" is
　　# a good value. If most of your content is binary, such as applications

　　#
　　# If the AddEncoding directives above are commented-out, then you
　　# probably should define those extensions to indicate media types:
　　#
　　AddType application/x-compress .Z
　　AddType application/x-gzip .gz .tgz
　　#
　　# AddHandler allows you to map certain file extensions to "handlers":
　　# actions unrelated to filetype. These can be either built into the server
　　# or added with the Action directive (see below)
　　#
　　# To use CGI scripts outside of ScriptAliased directories:
　　# (You will also need to add "ExecCGI" to the "Options" directive.)

　　#AddHandler cgi-script .cgi
　　# For type maps (negotiated resources):
　　#AddHandler type-map var
　　#
　　# Filters allow you to process content before it is sent to the client.
　　#
　　# To parse .shtml files for server-side includes (SSI):
　　# (You will also need to add "Includes" to the "Options" directive.)

　　#AddType text/html .shtml
　　#AddOutputFilter INCLUDES .shtml

　　# Customizable error responses come in three flavors:

　　（2）、增加mod_jk.conf配置文件。這里我將host表中的ip指向服務器，并將域名seller.linuxidc.com和trader.linuxidc.com也一并指向到此服務器

　　4、進行訪問：
　　配合上邊的三個文件的配置，我就可以通過
　　http://seller.linuxidc.com/MicSeller/
　　http://trader.linuxidc.com/MicTrader/
　　訪問指定的項目了
　　5、如果是靜態(tài)html文件項目的訪問咋辦？
　　就在我們的http.conf項目中的配置更改如下：
　　<VirtualHost *:80>
　　DocumentRoot /usr/local/static
　　ServerName static.linuxidc.com
　　ErrorLog logs/static-error_log.log
　　CustomLog logs/static-access_log.log common
　　# JkMount /* worker1
　　</VirtualHost>
　　就是不做轉發(fā)了，將JkMount 這行去掉
　　6、如果是我想配合php也一并部署到一個節(jié)點上行嗎？
　　經(jīng)過測試，在windows下沒有問題。安裝完畢php后，直接配置部署php相關模塊在httpd.conf中，還是老樣子，只要不指定JkMount.請求就不會轉發(fā)到tomcat。
　　總結：上邊我只是配置了java項目的虛擬主機配置方案。更多的時候是為了兼容php或者apache直接進行靜態(tài)文件的訪問。如果只是想在tomcat前放個apache，有更簡單的方法，ajp反向代理，直接進行8009端口轉發(fā)。
