JAVA operating environment: j2sdk-1_4_2_05

Database Server: MySQL-4.0.20d

Web server: Tomcat 5.0.27

JDBC driver: mysql-connector-java-3.0.14-production-bin.jar

1. Build JAVA operating environment

(1) Download j2sdk-1_4_2_05-linux-i586-rpm.bin from Sun

(2) For document read executable document:

[root@eframe62 tuzq]# chmod +x j2sdk-1_4_2_05-linux-i586-rpm.bin

(3) Execute self-extracting files:

[root@eframe62 tuzq]# ./ j2sdk-1_4_2_05-linux-i586-rpm.bin

(4) Decompress to generate rpm file j2sdk-1_4_2_05-linux-i586-rpm, install rpm:

[root@eframe62 tuzq]# rpm ? ivh j2sdk-1_4_2_05-linux-i586-rpm

(5) The file is installed in/usr/java/j2sdk1.4.2_05 directory, for convenience to make a simple connection in/usr directory:

[root@eframe62 usr]# ln ? s /usr/java/j2sdk1.4.2_05 jdk

(6) Adding environmental variables:

[root@eframe62 usr]# export JAVA_HOME=/usr/jdk

[root@eframe62 usr]# export CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib:.

[root@eframe62 usr]# export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

(7) Test JAVA runtime environment: write a java program to verify

[root@eframe62 usr]# vi HelloWorld.java

Enter the following:

public class HelloWorld{

public static void main(String args[]){

System.out.println("Hello，Wrold");

}

}

Write to disk and exit editor:

:wq

[@more@]

[root@eframe62 usr]# javac HelloWorld.java

(No mistakes)

[root@eframe62 usr]# java HelloWorld

Hello,World

The Java operating environment is set up.

2. Install MySQL database

MySQL database server can be downloaded from www.mysql.com. One is the binary version (compiled) mysql-standard-4.0.20-pc-linux-i686.tar.gz, installed as follows:

(1) Add users and groups named mysql:

[root@eFrame62 root]# groupadd mysql

[root@eFrame62 root]# useradd -g mysql mysql

(2) Extract the file to/usr/local directory:

[root@eFrame62 root]# cd /usr/local

[root@eFrame62 local]# gunzip

< /home/tuzq/mysql-standard-4.0.20-pc-linux-i686.tar.gz | tar xvf ? 　　 　　（3）创建一个方便使用的连接： 　　 　　[root@eFrame62 local]# ln -s /usr/local/mysql-standard-4.0.20-pc-linux-i686 mysql 　　 　　（4）执行mysql_install_db脚本，初始化数据库（创建系统数据库和表）： 　　 　　[root@eFrame62 local]# cd mysql 　　 　　[root@eFrame62 mysql]# scripts/mysql_install_db --user=mysql 　　 　　如果出现类似下面错误，加上--force参数： 　　 　　Neither host 'eframe62' and 'localhost' could not be looked up with ./bin/resolveip 　　 　　（5）修改所有者： 　　 　　[root@eFrame62 mysql]# chown -R root　. 　　 　　[root@eFrame62 mysql]# chown -R mysql data 　　 　　[root@eFrame62 mysql]# chgrp -R mysql . 　　 　　（6）启动数据库服务器： 　　 　　[root@eFrame62 mysql]# bin/mysqld_safe --user=mysql & 　　 　　另一种是RPM版本，包括：MySQL-server-4.0.20-0.i386.rpm（服务器）和MySQL-client-4.0.20-0.i386.rpm（客户程序）。执行下面的命令安装，会自动执行上面的操作，启动好服务器： 　　 　　rpm -ivh MySQL-server-4.0.20-0.i386.rpm 　　 　　rpm -ivh MySQL-client-4.0.20-0.i386.rpm 　　 　　注意：RPM版本的MySQL的安装目录有所不同，主要有下面一些目录： 　　 　　l　　　　　/usr/bin：客户程序和脚本 　　 　　l　　　　　/usr/sbin：mysqld服务程序 　　 　　l　　　　　/var/lib/mysql：日志文件和数据库 　　 　　如果不能正常启动服务，可能需要修改/var/lib/mysql的所有者为mysql： 　　 　　chown -R mysql:mysql /var/lib/mysql 　　 　　 　　 　　MySQL初始的root口令为空，需要修改。为了能够使用客户工具（如Windows下的图形工具）远程连接，需要增加权限： 　　 　　[root@eFrame62 mysql]# mysql -u root ?p 　　 　　mysql>

use mysql

mysql> grant all privileges on *.* to root@"%" identified by '012345' with grant option;

The above command creates a super account that can be logged in as root from any machine, password 012345. This allows you to log in and manipulate with convenient graphical tools, including changing root's password.

3. Install Tomcat

Tomcat can be downloaded from www.jakarta.org as a binary package (compiled): jakarta-tomcat-5.0.27.tar.gz.

(1) Extract the file to/usr/local directory

[root@eFrame62 local]# gunzip < /home/tuzq/jakarta-tomcat-5.0.27.tar.gz | tar xvf ?

(2) Create convenient connections

[root@eFrame62 local]# ln -s /usr/local/jakarta-tomcat-5.0.27.tar.gz tomcat

(3) Set JDK path

[root@eFrame62 local]# cd tomcat

[root@eFrame62 tomcat]# vi bin/catalina.sh

Add at the beginning of catalina.sh:

export JAVA_HOME=/usr/jdk

export CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib:.

export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

(4) Start Tomcat

[root@eFrame62 tomcat]# bin/startup.sh

Enter http://machine domain name or IP address:8080/in the browser to display Tomcat welcome interface.

5) Stop Tomcat

[root@eFrame62 tomcat]# bin/shutdown.sh

(6) To start Tomcat automatically at system startup, add to/etc/rc.d/rc.local:

/usr/local/tomcat/bin/startup.sh

(7) Management of Tomcat

Modify/usr/local/tomcat/conf/tomcat-users.xml to add an administrator account (Tomcat needs to be restarted):

[root@eFrame62 tomcat]# vi conf/tomcat-users.xml

Insert the following line in:

Enter http://machine domain name or IP address:8080/admin in the browser to log in as administrator to enter the management interface.

(8) Creating Context Content

Create a standard Web application (such as quickstart): Include the WEB-INF directory, which has the classes and lib directories under it.

One way is to copy the entire directory to/usr/local/tomcat/webapps/and restart Tomcat, which loads automatically.

Another method is to copy the entire directory to a directory (such as/home/tuzq/quickstart). In the admin interface, select Tomcat Server/Service (Catalina)/Host(localhost) on the left, select Create New Context in the Host Actions drop-down box on the right, specify Document Base as/home/tuzq/quickstart, specify Path as/quickstart, and set Use Naming to True to use JNDI.

This allows you to access Web application content via http://machine domain name or IP address:8080/quickstart.

(9) Setting up JDBC

To access the specified database, copy the corresponding JDBC driver (in this case mysql-connector-java-3.0.14-production-bin.jar) to the directory/usr/local/tomcat/common/lib, Tomcat loads automatically at startup
