A total of the following steps are divided:

First, install the configuration JDK

Second, install the configuration tomcat

Iii. installation of PostgreSQL

Four, Tomcat test

V. Connecting to the Database

The software you need:

j2sdk-1_4_2-linux-i586-rpm.bin
jakarta-tomcat-4.1.30.tar.gz
postgresql-7.4.1-1PGDG.i386.rpm
postgresql-jdbc-7.4.1-1PGDG.i386.rpm
postgresql-server-7.4.1-1PGDG.i386.rpm
postgresql-libs-7.4.1-1PGDG.i386.rpm

All of these software are/download in a backup.

#mkdir/download

1 Installation configuration JDK

Download Address: http://java.sun.com/j2se/1.4.2/download.html

Download the RPM package, which is actually a. bin file

#chmod u+x J2sdk-1_4_2-linux-i586-rpm.bin
#./j2sdk-1_4_2-linux-i586-rpm.bin
#rpm-IVH j2sdk-1_4_2-linux-i586-rpm
#cd/usr/java/
#ln-S j2sdk1.4.2/jdk/
To set environment variables:
Don't write about it in the/etc/profile. That would cause the JDK to be available for each user to start.
Because you want to use Tomcat, write to Tomcat's home directory.
#vi/HOME/TOMCAT/.BASHRC (also can be. bash_profile)
Export JAVA_HOME=/USR/JAVA/JDK
Export path= $PATH: $JAVA _home/bin
Export Classpath= $JAVA _home/lib
Su to Tomcat users to see if they can use
#su-tomcat
$javac
$java
Do you have a show? If so, the JDK configuration is successful.
Re-su to root
