Build a WEB application environment in Linux

Article Title: Build a WEB application environment in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

JAVA environment: j2sdk-1_4_2_05

Database Server: MySQL-4.0.20d

Web server: Tomcat5.0.27

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

1. Build a JAVA Runtime Environment

(1) to Sun Company download j2sdk-1_4_2_05-linux-i586-rpm.bin

(2) Change the file to an executable file:

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

(3) execute the self-extracting file:

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

(4) decompress to generate the 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 the/usr/java/j2sdk1.4.2 _ 05 directory. To facilitate a simple connection in the/usr directory:

[Root @ eframe62 usr] # ln? S/usr/java/j2sdk1.4.2 _ 05 jdk

(6) add environment 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 the JAVA Runtime Environment: Write a java program for verification.

[Root @ eframe62 usr] # vi HelloWorld. java

Enter the following content:

Public class HelloWorld {

Public static void main (String args []) {

System. out. println ("Hello, Wrold ");

}

}

Write the disk and exit the Editor:

: Wq

[Root @ eframe62 usr] # javac HelloWorld. java

(No error)

[Root @ eframe62 usr] # java HelloWorld

Hello, World. The JAVA Runtime Environment has been set up.

2. Install the MySQL database

The MySQL database server can be downloaded from www.mysql.com. One is the two-step Installation Tool (compiled mysql-standard-4.0.20-pc-linux-i686.tar.gz). The installation is as follows:

(1) Add a user and group named mysql:

[Root @ eFrame62 root] # groupadd mysql

[Root @ eFrame62 root] # useradd-g mysql

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

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

[Root @ eFrame62 local] # gunzip

(3) create a convenient connection:

[Root @ eFrame62 local] # ln-s/usr/local/mysql-standard-4.0.20-pc-linux-i686 mysql

(4) execute the mysql_install_db script to initialize the database (Create a system database and table ):

[Root @ eFrame62 local] # cd mysql

[Root @ eFrame62 mysql] # scripts/mysql_install_db -- user = mysql

If an error similar to the following occurs, add the -- force parameter:

Neither host 'eframe62' and 'localhost' cocould not be looked up with./bin/resolveip

(5) modify the owner:

[Root @ eFrame62 mysql] # chown-R root.

[Root @ eFrame62 mysql] # chown-R mysql data

[Root @ eFrame62 mysql] # chgrp-R mysql.
