as5.4安装jdk及tomcat
Base OS:Redhat5.4.jdk version：jdk-6u22-linux-i586-rpm.bin
tomcat version： apache-tomcat-5.5.31
download jdk form official website:http://java.sun.com/
jdk-6u22-linux-i586-rpm.bin
download tomcat from official website:http://tomcat.apache.org/
apache-tomcat-5.5.31.tar.gz
1.Setup JDK
#cp jdk-6u22-linux-i586-rpm.bin /usr
#cd /usr
#chmod 755jdk-6u20-linux-i586-rpm.bin
#sh jdk-6u22-linux-i586-rpm.bin
Excute this package，it will auto extra JDK RPM package and finish the installation，after the installation you will see /usr/java/jdk1.6.0_22 fold,this is the JDK home directory.
2. Configure Java Environment, edit /etc/profile，add these content：
[*] JAVA_HOME="/usr/java/jdk1.6.0_22"
[*] export JAVA_HOME
[*] PATH=$JAVA_HOME/bin:$PATH
[*] export PATH
[*] CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$CLASSPATH
[*] export CLASSPATH
3.Bring the enviroment effect with this command:
#source /etc/profile
4. You can check the enviroment with echo command in terminal:
# echo $JAVA_HOME
# echo $CLASSPATH
# echo $PATH
if you find the echo value incorrect，please check the content previous。
5.Checking if JDK install correctly：
# java -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)
you can see the java version info,if you see the info like these，it mean you make it, successfully!
6.tomcat installation
#cp apache-tomcat-5.5.31.tar.gz /usr/local/
# cd /usr/local/
#tar -zxpf apache-tomcat-5.5.29.tar.gz
#mv apache-tomcat-5.5.31.tar.gz tomcat5.5
7.Configrate tomcat enviroment, edit/etc/profile,add these content：
[*]export CATALINA_HOME="/usr/local/tomcat5.5"
[*]export CATALINA_BASE="/usr/local/tomcat5.5"
8.Bring the enviroment effect.
# source /etc/profile
In here, the configration almost finished，now we can start tomcat：
# /usr/local/tomcat5.5/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat5.5
Using CATALINA_HOME: /usr/local/tomcat5.5
Using CATALINA_TMPDIR: /usr/local/tomcat5.5/temp
Using JRE_HOME: /usr/java/jdk1.6.0_22
Using CLASSPATH: /usr/local/tomcat5.5/bin/bootstrap.jar
if startup failed，you can try to run this first /usr/local/tomcat5.5/bin/shutdown.sh，
and then /usr/local/tomcat5.5/bin/startup.sh
9.Checking the services ：
# ps -ef | grep tomcat
root 11362 10 02:37 pts/0 00:00:02 /usr/java/jdk1.6.0_22/bin/java -Djava.util.logging.config.file=/usr/local/tomcat5.5/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/local/tomcat5.5/common/endorsed -classpath /usr/local/tomcat5.5/bin/bootstrap.jar -Dcatalina.base=/usr/local/tomcat5.5 -Dcatalina.home=/usr/local/tomcat5.5 -Djava.io.tmpdir=/usr/local/tomcat5.5/temp org.apache.catalina.startup.Bootstrap start
# netstat -tanpen

From here, you can see the services if working normally.
10. Now we access server 8080 port with browser，this is the normal website:
