1.j2sdk-1_4_2-windows-i586.exe //jdk
2.mysql-4.0.20d-win.zip //mysql数据库
3.mysqlcc-0.9.4-win32.zip //mysqlGUI控制
4.jakarta-tomcat-5.0.27.exe //tomcat服务器
5.mysql-connector-java-3.0.14-production.zip //内含mysql驱动
安装步骤:
1.安装jdk
2.安装tomcat
3.安装mysql
4.安装mysqlcc
5.将驱动包解压,拷贝mysql-connector-java-3.0.14-production-bin.jar到tomcat/common/lib下
或者下载mm.mysql-2.0.14-you-must-unjar-me.jar,解压后拷贝其中的mm.mysql-2.0.14-bin.jar
Tomcat5.0配置 本例使用安装密码 198277
1.配置manager 管理应用程序
在conf/server.xml 中
添加如下
<Service name="Catalina">
...
<Context path="/manager" debug="0" privileged="true"
docBase="/usr/local/kinetic/tomcat5/server/webapps/manager">
</Context>
</Service>
限制ip访问配置
<Context path="/manager" debug="0" privileged="true"
docBase="/usr/local/kinetic/tomcat5/server/webapps/manager">
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127.0.0.1"/>
</Context>
测试为:/jishu511524536http://localhost:8080/manager/html'>http://localhost:8080/manager/html
2.配置JDBCRealm容器管理安全,以mysql-4.0数据库为例
a.拷贝驱动mm.mysql-2.0.14-bin.jar到common/lib/下
b.在数据库ycg中建表
create table users (
user_name varchar(15) not null primary key,
user_pass varchar(15) not null
);
create table user_roles (
user_name varchar(15) not null,
role_name varchar(15) not null,
primary key (user_name, role_name)
);
c.修改server.xml如下(默认数据库为root,无密码,如果有形如:connectionURL="jdbc:mysql://localhost/authority?
user=dbuser&password=dbpass")
<Realm className="org.apache.catalina.realm.JDBCRealm" debug="99"
driverName="org.gjt.mm.mysql.Driver"
connectionURL="jdbc:mysql://localhost/ycg?user=root"
connectionName="" connectionPassword=""
userTable="users" userNameCol="user_name" userCredCol="user_pass"
userRoleTable="user_roles" roleNameCol="role_name" />
d.在数据库中添加入tomcat的默认配置数据:
+-----------+-----------+
user_name role_name
+-----------+-----------+
admin admin
admin manager
both role1
both tomcat
role1 role1
tomcat tomcat
+-----------+-----------+
+-----------+-----------+
user_name user_pass
+-----------+-----------+
tomcat tomcat
both tomcat
role1 tomcat
admin 198277
+-----------+-----------+
e.启动mysql,启动tomcat,此后tomcat将从数据库中读用户规则认证.默认的conf/tomcat-users.xml失效
3.DBCP的配置
a.设置
<parameter>
<name>removeAbandoned</name>
<value>true</value>
</parameter>
可使失效的数据连接重新启用.
配套设置
<parameter>
<name>removeAbandonedTimeout</name>
<value>60</value>
</parameter>
失效时间
如果要写入日志
设置
<parameter>
<name>logAbandoned</name>
<value>true</value>
</parameter>
以上三个默认都是false
b.以mysql为例,配置数据连接池
c.配置新的用户与数据库,必须设定密码,空密码将导致连接失败
e.
指定root密码:mysqladmin -u root -h localhost password "198277"
(需修改上面的jdbcrealm设置connectionURL="jdbc:mysql://localhost/ycg?user=root&password=198277")
命令mysql进入匿名连接到服务器
密码访问
shell> mysql -h host -u user -p
Enter password: ********
//如果root没有密码,以下是不成功的.(试过了)
mysql> GRANT ALL PRIVILEGES ON *.* TO javauser@localhost
-> IDENTIFIED BY 'javadude' WITH GRANT OPTION;
mysql> create database javatest;
mysql> use javatest;
mysql> create table testdata (
-> id int not null auto_increment primary key,
-> foo varchar(25),
-> bar int);
在conf/server.xml中<host></host>中添加
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_DBTest_log." suffix=".txt"
timestamp="true"/>
<Resource name="jdbc/TestDB"
auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/TestDB">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<!-- Maximum number of dB connections in pool. Make sure you

</parameter>
-->
<!-- Class name for the official MySQL Connector/J driver -->
<parameter>

<value>com.mysql.jdbc.Driver</value>
</parameter>
<!-- The JDBC connection url for connecting to your MySQL dB.
The autoReconnect=true argument to the url makes sure that the
mm.mysql JDBC Driver will automatically reconnect if mysqld closed the
connection. mysqld by default closes idle connections after 8 hours.

<name>url</name>
<value>jdbc:mysql://localhost:3306/javatest?autoReconnect=true</value>
