PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=$JAVA_HOME/lib/tools.jar
export JAVA_HOME CLASSPATH
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=$JAVA_HOME/lib/tools.jar
export JAVA_HOME CLASSPATH
e) source /etc/profile
f) 验证安装：java –version

g) cd /usr/local/mysql
h) chown -R mysql .
i) chgrp -R mysql .
j) /usr/local/mysql/bin/mysql_install_db --user=mysql
k) chown -R root .
l) chown -R mysql var
m) bin/mysqld_safe --user=mysql &>/dev/null
n) 修改root用户密码：./mysqladmin -u root password '123456'
o)
p) 创建名为test1的数据库，并建立pet的表：
q) mysql> Create database test1 use test1
r) mysql> CREATE TABLE pet (name VARCHAR(20), owner VARCHAR(20), species VARCHAR(20), sex CHAR(1), birth DATE, death DATE);
s) 在本地新建一个文件名为pet.txt内容如下：
name owner species sex birth death

t) 导入pet.txt到pet表
u) mysql> load data local infile '/pet.txt' into table pet;
(四) 安装mysql-connector-java-3.2.0-alpha
a) tar zxvf mysql-connector-java-3.2.0-alpha.tar.gz
b) cp mysql-connector-java-3.2.0-alpha-bin.jar /usr/local/jdk/lib/
c) cp mysql-connector-java-3.2.0-alpha-bin.jar /usr/local/tomcat/common/lib/
(五) 配置mysql数据源
a) vi /usr/local/tomcat/conf/tomcat-users.xml 加入如下内容：
重启tomcat
b)
http://192.168.1.8:8080/admin
用户名：admin 密码：111111。选择Resources－Data sources进入配置数据源界面，选择Data Source Actions －>选择Create New Data Source,进入配置详细信息界面，内容如下：
JNDI Name: jdbc/mysql
Data Source URL: jdbc:mysql://192.168.1.8/test1
JDBC Driver Class: org.gjt.mm.mysql.Driver
User Name: root
Password: 123456
Max. Active Connections: 4
Max. Idle Connections: 2
Max. Wait for Connection: 500
Validation Query:
c) vi /usr/local/tomcat/conf/web.xml：在前加入如下内容：
d) vi /usr/local/tomcat/conf/Catalina/localhost/ROOT.xml 加入如下
e) 测试连接代码：vi /usr/local/tomcat/webapps/ROOT/test.jsp

Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
String sql="SELECT * FROM "+tableName;
ResultSet rs = statement.executeQuery(sql);
//获得数据结果集合
ResultSetMetaData rmeta = rs.getMetaData();
//确定数据集的列数，亦字段数
int numColumns=rmeta.getColumnCount();
// 输出每一个数据值
out.print("name"+" ");
out.print("owner"+" ");
out.print("species");
out.print("species");
out.print("birth");
out.print("death");
out.print("

");
while(rs.next()) {
out.print(rs.getString(1)+" ");
out.print(rs.getString(2)+" ");
out.print(rs.getString(3));
out.print("yuan RMB");
out.print("
