Hardware and Software Environment

ubuntu12.04+jdk1.7+eclipse+tomcat7.0

Table of Contents

1. Install JDK1.7, configure the Java environment

2. Install Eclipse

3. Installing Tomcat7.0

1. Install JDK1.7, configure the Java environment

Step 1: Download the JDK

Step 2: Unzip into the/usr/local

sudo tar-zxvf jdk-7u67-linux-x64.tar.gz-c/usr/local

Step 3: Configure environment variables

Open/etc/profile file: sudo gedit/etc/profile

Increase on the last side of the file:

Export java_home=/usr/lib/jvm/jdk1.7.0_67
Export path= #PATH: $JAVA _home/bin: $JAVA _home/jre/bin
Export classpath= $CLASSPATH:.: $JAVA _home/lib/tools.jar: $JAVA _home/jre/lib/dt.jar

When configuring path and classpath, be careful to add the original path and classpath as shown above.

Configure the environment variables, you can restart, the easier way is to source/etc/profile.

Finally, use Javac and Java to see if the environment variable is installed successfully.

Java-version

Javac-version

2. Install Eclipse

Step 1: Download eclipse

Step 2: Unzip Eclipse to/opt

sudo tar-zxvf eclipse-jee-luna-r-linux-gtk-x86_64.tar.gz-c/opt

Step 3: Create a command-line startup script for Eclipse

Create a startup script in the/usr/bin directory eclipse

sudo vim/usr/bin/eclipse

Then add the following to the file:
#!/bin/sh
Export Eclipse_home= "/home/opt/eclipse"

#使root用户的环境变量生效

Source/etc/profile
$ECLIPSE _home/eclipse $*
Modify the permissions of the script to make it executable and execute the following command:
sudo chmod +x/usr/bin/eclipse

3. Installing Tomcat7.0

Step 1: Download tomcat

Step 2: Unzip tomcat7.0 to/opt

sudo tar-zxvf apache-tomcat-7.0.55.tar.gz-c/opt

Step 3: Setup Environment Variables

sudo vi/etc/profile

At the bottom, add:
Export catalina_home=/opt/apache-tomcat7.0.40

Make it effective

Source/etc/profile

Step 4: Modify catalina.sh

CD $CATALINA _home/bin

sudo vim catalina.sh

Find the # OS specific support. $var _must_ is set to either true or false line

Define again Catalina_home and java_home on this:

catalina_home=/opt/apache-tomcat7.0.55

java_home=/usr/local/jdk1.7.0_67

Save exit

Step 5: Try to start tomcat

sudo./bin/startup.sh

If the following is displayed without any exceptions, the startup succeeds:

Using catalina_base:/opt/apache-tomcat7.0.55
Using Catalina_home:/opt/apache-tomcat7.0.55
Using Catalina_tmpdir:/opt/apache-tomcat7.0.55/temp
Using Jre_home:/usr/local/java/jdk1.7.0_67
Using CLASSPATH:/opt/apache-tomcat7.0.55/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

Step 6: Stop Tomcat

sudo./bin/shutdown.sh

Step 7: Open the Default Web page to see if Tomcat is working properly

http://localhost:8080
