秀脱linux笔记之tomcat6实战篇 转载请说明出处： http://hi.baidu.com/xiutuo/blog/item/4222e119ad9a914743a9adbc.html 环境： -------------------------------------------- 操作系统：centos 4.5_x86 数据库oracle 10.2.01_x86_32 jre：1.6：jdk-6u1-linux-i586-rpm.bin tomcat6.0:编译好的二进制软件包apache-tomcat-6.0.13.tar.gz tomcat6.0 安装路径：/usr/local/tomcat6 oracle jdbc:class12.jar 软件包存放的路径：/home/xiutuo/software/ -------------------------------------------- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 一：安装jre 1.安装jre软件包， # cd /home/xiutuo/software 进入软件包存放目录 # chmod a+x jdk-6u1-linux-i586-rpm.bin 使它有执行权限 # ./jdk-6u1-linux-i586-rpm.bin 多敲几个空格，然后看到[yes]的时候输入yes，回车 然后在当前目录下就生成了jdk-6u1-linux-i586-rpm # rpm -ivh jdk-6u1-linux-i586-rpm 安装jdk 如果之前有其他老版本的jdk，卸载掉，如： rpm -e j2sdk-1.4.1-fcs 2.：设置环境变量 仅设置某个用户而不是所有用户可以修改~/.cshrc,~/.bash_profile文件, 追加下面一段,如果为所有用户以及以后添加的用户都加上环境变量的话, 追加/etc/profie文件. ***主意不要在profile和~/.cshrc或~/.bash_profile中重复追加** 这里： # vi /etc/profile //java //如果你安装的j2sdk的路径不一样,请自行修改 JAVA_HOME=/usr/java/jdk1.6.0_01 export JAVA_HOME CLASSPATH=/usr/java/jdk1.6.0_01/lib:/usr/java/jdk1.6.0_01/jre/lib export CLASSPATH PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin export PATH JRE=/usr/java/jdk1.6.0_01/jre export JRE 3：立即生效 //如果你修改的是/etc/profile # source /etc/profile //如果你修改的是~/.cshrc # source ~/.cshrc //如果你修改的是~/.bash_profile # source ~/.bash_profile 4：测试成功否 # java -version 出现 java version "1.4.2" //这里比较怪，本来是jre是1.6这里居然…… gcj (GCC) 3.4.6 20060404 (Red Hat 3.4.6-8) Copyright (C) 2006 Free Software Foundation, Inc.

The file is currently setup for running Tomcat 4.1.x, so it is necessary to edit it and change the classname from BootstrapService to Bootstrap. Note that the Commons-Daemon JAR file must be on your runtime classpath to run Tomcat in this manner. The Commons-Daemon JAR file is in the Class-Path entry of the bootstrap.jar manifest, but if you get a ClassNotFoundException or a NoClassDefFoundError for a Commons-Daemon class, add the Commons-Daemon JAR to the -cp argument when launching jsvc. 三：配置tomcat应用实列 浏览器输入：http://localhost:8080/ 点击manager：输入刚才配置的tomcat用户：用户admin和密码admin 配置虚拟目录test，并通过 http://localhost:8080/test/来访问 1.手动配置 在 /usr/local/tomcat6/webapps目录下， 建立testdir目录，把相关jsp原代码放入该目录。 新建test.xml，并配置context和连接池 # cd /usr/local/tomcat6/webapps/ # vi test.xml 内容如下： <Context path="/test" docBase="/usr/local/tomcat6/webapps/testdir" debug="5" reloadable="true" crossC> <Resource name="jdbc/myoracle" auth="Container" type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@192.168.1.159:1521:db01" username="oracele_db_user" password="db_owner_password" maxActive="20" maxIdle="10" maxWait="-1"/> </Context> 其中： context path="/test"----就是http://localhost:8080/test/里的test虚拟目录 <Resource name="jdbc/myoracle" ---- myoracle连接池名 url="jdbc:oracle:thin:@192.168.1.159:1521:db01" --192.168.1.159:1521:db01是数据库ip:端口:SID， username="oracele_db_owner_user" password="db_owner_password" ---分别是数据库用户和用户密码 打开http://localhost:8080/，点击manager，进入后， 在Deploy 这一栏里 Deploy directory or WAR file located on server Context Path (optional): /test XML Configuration file URL: /usr/local/tomcat6/testdir/test.xml WAR or Directory URL: 留空即可 点击deploy按钮。即配置了一个web应用 2.通过war文件来配置。 在WAR file to deploy这一栏里 Select WAR file to upload：通过浏览把war文件路径添加上， 就可以架设应用事例了，可以参照官方文档Sample应用实例 ---------------------------------------------------- Sample Application The example app has been packaged as a war file and can be downloaded here (Note: make sure your browser doesn't change file extension or append a new one). The easiest way to run this application is simply to move the war file to your CATALINA_HOME/webapps directory. Tomcat will automatically expand and deploy the application for you. You can view it with the following URL (assuming that you're running tomcat on port 8080 as is the default): http://localhost:8080/sample If you just want to browse the code you can unpack the war file with the jar command. jar -xvf sample.war --------------------------------------------------- ************************************** 补充： 当然可以把test.xml的内容放在 /usr/local/tomcat6/conf/server.xml中的<host>与</host>之间 然后这个应用的程序的文件夹里新建 WEB-INF/web.xml 内容如下： <resource-ref> <description>Oracle Datasource example</description> <res-ref-name>jdbc/myoracle</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> 测试jdbc代码： <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <sql:query var="rs" dataSource="jdbc/TestDB"> select id, foo, bar from testdata </sql:query> <html> <head> <title>DB Test</title> </head> <body> <h2>Results</h2> <c:forEach var="row" items="${rs.rows}"> Foo ${row.foo}<br/> Bar ${row.bar}<br/> </c:forEach> </body> </html> *************************************** 其他的数据源连接池子参照官方文档， 基本上修改test.xml里的<Resource里的内容就好了 *************************************** |
