Procedures and considerations for deploying a Java Web project with Tomcat under Linux

Procedures and considerations for deploying a Java Web project with Tomcat under Linux

I. Installing the JDK
Download Java SE 6 Update 27 to Http://www.oracle.com/technetwork/java/javase/downloads/index.html
Choose Linux x64-rpm Installer or Linux x86-rpm based on the operating system Installer
Download Jdk-6u27-linux-x64-rpm.bin and put it in the/home directory, of course, anywhere else.
Note: Linux is case-sensitive!!!
Add executable permissions to this file: chmod +x Jdk-6u27-linux-x64-rpm.bin

Then execute this file:. jdk-6u27-linux-x64-rpm.bin

Configure the Java environment variables, modify the/etc/profile file: Vi/etc/profile then press the letter I into insert mode,
Shift+insert paste;
ESC exits edit;
: Wq save exit;
: q! does not save the exit;
Add the following lines at the end:
#set Java evironment
Java_home=/usr/java/jdk1.6.0_27
Classpath=.: $JAVA _home/lib.tools.jar
Path= $JAVA _home/bin: $PATH
Export Java_home CLASSPATH PATH

Use the echo command at the terminal to check environment variable settings:
#echo $JAVA _home
#echo $CLASSPATH
#echo $PATH
Check that the JDK is installed successfully:
#java-version
If you see the JVM version and related information, the installation is successful

Two. Tomcat Configuration Deployment
(1) file upload:
Download apache-tomcat-6.0.33.tar.gz on tomcat website
upload to the Linux server
(2) Unzip the file as follows: TAR-ZXVF Apache-tomcat-6.0.33.tar.gz-c/usr/local
(3) Compressed files are extracted to the/usr/local directory, forming a new folder apache-tomcat-6.0.33, Inside is all the Tomcat-related execution configuration files.
(4) Modify the configuration file to increase the environment variable information for Java. Under/usr/local/apache-tomcat-6.0.33/bin file catalina.sh Add the following information to the file header (note case):
Export java_home=/usr/java/jdk1.6.0_
Export classpath=.: $CLASSPATH: $JAVA _home/lib: $JAVA _home/jre/lib
Export path= $PATH: $JAVA _home/bin: $JAVA _ Home/jre/bin
(5) executable program under/usr/local/apache-tomcat-5.5.17/bin
to start Tomcat #   ./startup.sh
Turn off Tomcat #   ./shutdown.sh
to see if startup success can be entered PS axuwf|grep Java, if there are a lot of results, is the start success.
You can also netstat-lnpt to see if Port 8088 is used. If it is used, the boot is successful.
(6) test Tomcat open IE, enter URL HTTP://IP address:8080    can see Tomcat's launch Welcome page, prove that Tomcat is configured correctly
in tomcat/ The default port number can be modified in Conf/server.xml: For example, change to 8088, note: Do not add the <Context> element as in Windows

Three. Deployment of Java Web Apps
Export the Web application into the war package file in Eclipse and copy it into the Tomcat/wabapps directory
The folder of the referenced items is also tested in the Tomcat/wabapps directory
Start Tomcat again after shutting down
Enter HTTP://IP address when accessing: 8088/war file name/....
For example, the war file is named Wapinfo.war
Then enter HTTP://IP address: 8088/wapinfo/....
To access

To facilitate the management of the project, you can modify the/root/apache-tomcat-6.0.33/conf/tomcat-users.xml file, at the end add
<role rolename= "Manager"/>
<role rolename= "admin"/>
<user username= "admin" password= "123456" roles= "Admin,manager"/>
Click the Tomcat Manager link in the upper-left corner of the Tomcat welcome page to view the running apps after entering admin,123456.
