JDK installation and Tomcat configuration for JSP environment setup

Step 1 of JSP environment setup: Install JDK

1) download the installer from the official website: http://java.sun.com/javase/downloads/index.jsp. you only need to download the installer and install it.

2) install the JDK package

 
 

  
  
[root@linuxas src]cd /usr/local/src  
  
  
[root@linuxas src]# chmod u+x jdk-6u14-linux-i586.bin   
  
  
[root@linuxas src]#./jdk-6u14-linux-i586.bin  
 
 

Enter yes, and wait until the installation is complete.

 
 

  
  
[root@linuxas src]# rm -f jdk-6u14-linux-i586.bin   
  
  
[root@linuxas src]# ls  
  
  
apache-tomcat-6.0.20.tar.gz jdk1.6.0_14  
  
  
[root@linuxas src]# pwd  
  
  
/usr/local/src  
  
  
[root@linuxas src]# cd jdk1.6.0_14/  
  
  
[root@linuxas jdk1.6.0_14]# ls  
  
  
bin jre README_ja.html sample  
  
  
COPYRIGHT lib README_zh_CN.html src.zip  
  
  
db LICENSE register.html THIRDPARTYLICENSEREADME.txt  
  
  
demo man register_ja.html  
  
  
include README.html register_zh_CN.html  
  
  
[root@linuxas jdk1.6.0_14]# pwd  
  
  
/usr/local/src/jdk1.6.0_14 
 
 

3) set Environment Variables

 
 

  
  
[root@linuxas lib]# vi /etc/profile 
 
 

Add the following content

 
 

  
  
export JAVA_HOME=/usr/local/src/jdk1.6.0_14  
  
  
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin: $PATH  
  
  
exportCLASSPATH=.:/usr/local/src/jdk1.6.0_14/lib:/usr/local/src/jdk1.6.0_14/jre/lib:$CLASSPATH 
 
 

4) Verify the JAVA installation result

 
 

  
  
[root@linuxas ~]# source /etc/profile  
  
  
[root@linuxas ~]# java -version  
  
  
java version "1.6.0_14"  
  
  
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)  
  
  
Java HotSpot(TM) Client VM (build 14.0-b16, mixed mode, sharing) 
 
 

Step 2 of JSP Environment Construction: install tomcat

1) download the installation package from the official website: http://tomcat.apache.org/download-60.cgi. select .tar.gzto download the package.

2) install tomcat

 
 

  
  
[root@linuxas ~]#cd /usr/local/src  
  
  
[root@linuxas src]# tar -zxvf apache-tomcat-6.0.20.tar.gz  
  
  
[root@linuxas src]# ls  
  
  
apache-tomcat-6.0.20 apache-tomcat-6.0.20.tar.gz jdk1.6.0_14  
  
  
[root@linuxas src]# mv apache-tomcat-6.0.20 /  
  
  
[root@linuxas src]# cd /  
  
  
[root@linuxas /]# mv apache-tomcat-6.0.20 tomcat  
  
  
[root@linuxas /]# ls  
  
  
bin dev home lost+found misc net proc sbin srv tmp usr  
  
  
boot etc lib media mnt opt root selinux sys tomcat var  
 
 

3) set Environment Variables

 
 

  
  
[root@linuxas tomcat]# vi /etc/profile 
 
 

Add the following statement:

 
 

  
  
export CATALINA_BASE=/tomcat  
  
  
export CATALINA_HOME=/tomcat 
 
 

At the same time, modify the following settings:

 
 

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

Add and become

 
 

  
  
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$CATALINA_HOME=/tomcat/bin  
  
  
[root@linuxas tomcat]# source /etc/profile 
 
 

4) start the service

 
 

  
  
[root@linuxas bin]# ./startup.sh   
  
  
Using CATALINA_BASE: /tomcat  
  
  
Using CATALINA_HOME: /tomcat  
  
  
Using CATALINA_TMPDIR: /tomcat/temp  
  
  
Using JRE_HOME: /usr/local/src/jdk1.6.0_14  
  
  
[root@linuxas bin]# ps aux | grep tomcat  
  
  
root 3468 7.6 10.4 219008 26772 pts/1 Sl 05:57 0:05 /usr/local/src/jdk1.6.0_14/bin/java -Djava.util.logging.config.file=/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/tomcat/endorsed -classpath :/tomcat/bin/bootstrap.jar -Dcatalina.base=/tomcat -Dcatalina.home=/tomcat -Djava.io.tmpdir=/tomcat/temp org.apache.catalina.startup.Bootstrap start  
  
  
root 3493 0.0 0.2 5152 696 pts/1 R+ 05:58 0:00 grep tomcat 
 
 

5) modify the basic configuration of tomcat

 
 

  
  
[root@linuxas tomcat]# cd conf  
  
  
[root@linuxas conf]# vi server.xml 
 
 

Find

 
 

  
  
< Connector port="8080" protocol="HTTP/1.1" 
  
  
connectionTimeout="20000" 
  
  
redirectPort="8443" /> 
 
 

Change the port to 80 and add the following statement URIEncoding = "UTF-8" useBodyEncodingForURI = "true" to support Chinese display.

6) set tomcat to start by default.

 
 

  
  
[root@linuxas ~]# vi /etc/rc.d/rc.local 
 
 

Add the following content

 
 

  
  
export JAVA_HOME=/usr/local/src/jdk1.6.0_14  
  
  
/tomcat/bin/startup.sh 
 
 

After modifying iptables settings, check the effect as follows:

If it is not started as a root user, perform the following operations:

 
 

  
  
# useradd tomcat  
  
  
# chown -R tomcat:tomcat /tomcat  
  
  
#vi /etc/rc.local 
 
 

Modify

 
 

  
  
/tomcat/bin/startup.sh  
 
 

Is

 
 

  
  
su - tomcat -c '/tomcat/bin/startup.sh'
