在Linux下配置JSP+TOMCAT+MYSQL环境

1 下载安装文件
 1) jdk-1_2_2_017-linux-i586.tar.gz
 下载地址
 2) jakarta-tomcat-4.1.31.tar.gz
 下载地址
 3) mysql-connector-java-3.1.6.tar.gz
 下载地址http://dev.mysql.com/downloads/connector/j/3.1.html

2 用root身份安装jdk,tomcat,mysql驱动
 1) 拷贝安装文件到/usr/local/目录
 cp /root/src/jdk-1_2_2_017-linux-i586.tar.gz /usr/local/
 cp /root/src/tar -zxvf ./jakarta-tomcat-4.1.31.tar.gz /usr/local/
 cp /root/src/tar -zxvf ./mysql-connector-java-3.1.6.tar.gz /usr/local/
 2) 解包
 cd /usr/local
 tar -zxvf ./jdk-1_2_2_017-linux-i586.tar.gz
 tar -zxvf ./jakarta-tomcat-4.1.31.tar.gz
 tar -zxvf ./mysql-connector-java-3.1.6.tar.gz
 3) 删除原安装文件
 rm -f ./*.tar.gz
 4) 拷贝mysql驱动
 cp ./mysql-connector-java-3.1.6/mysql-connector-java-3.1.6-bin.jar ./jakarta-tomcat-4.1.31/webapps/ROOT/WEB-INF/lib/

3 配置JDK环境变量
 修改/etc/profile,加入如下几行
 JAVA_HOME=/usr/local/jdk1.2.2
 JRE=/usr/local/jdk1.2.2/jre
 CLASSPATH=$JAVA_HOME/lib:$JRE/lib:/usr/local/jakarta-tomcat-4.1.31/webapps/ROOT/WEB-INF/lib/mysql-connector-java-3.1.6-bin.jar:.
 PATH=$PATH:$JAVA_HOME/bin:$JRE/bin:.

 export JAVA_HOME JRE CLASSPATH
 export PATH

4 启动TOMCAT
  /usr/local/jakarta-tomcat-4.1.31/bin/startup.sh

5 关闭TOMCAT
 /usr/local/jakarta-tomcat-4.1.31/bin/shutdown.sh

6 写mysql.jsp 测试
 <%@ page contentType="text/html;charset=gb2312"%>
 <%@ page import="java.sql.*"%>
 
 
 <%Class.forName("org.gjt.mm.mysql.Driver").newInstance();
 String url ="jdbc:mysql://localhost/phpbb?user=phpbb&password=phpbb&useUnicode=true&characterEncoding=8859_1";
 Connection conn= DriverManager.getConnection(url);
 Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
 String sql="show tables";
 ResultSet rs=stmt.executeQuery(sql);%>
 <%while(rs.next()) {%>
 <%=rs.getString(1)%>
 

 <%}%>
 <%rs.close();
 stmt.close();
 conn.close();
 %>
