How to deploy java web in cloud server

1. Preparation

1. Register an account

After the download is completed. You can go here to apply for a 15-day free trial of the 1GB cloud server ECS and a 30-day free trial of the cloud database RDS 5G.

2. Download putty and FileZlilla

The process of local remote SSH login to the personal Alibaba Cloud server is very simple, so I won’t go into details here

2. JDK installation

1. First download the JDK. After downloading it, upload the compressed package to the personal cloud server through FileZlilla

Open putty. Enter the IP address and follow the prompts to enter the username and password. (The password is the password you use to log in to the Alibaba Cloud homepage)

(tomcat is what will be installed in the next step)

Okay, then it will be It's very simple.

2. Configuration directory

Note: It is best to operate as root user

Create a new directory first:

[plain] view plain copy

1. cd usr

2. mkdir java

3. cd java

4. mkdir jdk

Then unzip the jdk tar file to the directory above:

[plain] view plain copy

1. ##tar zxvf jdk-8u73-linux-x64.gz -C /usr/java/jdk

The results are as follows:

3. Configure environment variables

Input:

#[plain]

view plain copy

vi /etc/profile

or

[plain]

view plain copy

##gedit /etc/profile

Add the following content:

[plain]

view plain copy

set java environment

1. export JAVA_HOME=/usr/java/jdk/jdk1.8.0_73

2. export JRE_HOME=/usr/java/jdk/jdk1.8.0_73/jre

3. ##export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

4. export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$JAVA_HOME:$PATH

5. Note that this should be changed to The corresponding jdk directory must be modified as the root user, otherwise it cannot be saved

Execute after saving:

[plain]

view plain copy

##source /etc/profile

1. Verify installation:

Input:

[plain]

view plain copy

java -version

1. 
   The following appears, indicating that the installation is successful

   

   3. Configure tomcat

   1. Download tomcat, go to download, here the author uses It is tomcat7. At the same time, download tomcat to the local computer and upload the compressed package to the personal cloud server through FileZlilla.

   

   This is after the upload is successful:

   

   2. Installation

   Here I install tomcat into /usr/java/tomcat.

   Execute

   [plain] view plain copy

   4. Upload java web from local Project

   1. War package upload

   This is a locally packaged war package.

   Here I directly use the previously packaged war package war package, open FileZilla, and then select

   . Note that the personal cloud server must choose the correct address, otherwise you have to cp here. Remember to put the war package under webapps under tomcat

   2, then open the browser and enter

   http://120.24.19.24:8080 /JavaHelloWorld-0.0.1-SNAPSHOT/

   Found that it can be accessed!

   Of course, you can also go to the cloud server to view the war package:

   

   Instance access to this article: http:// 120.24.19.24:8080/JavaHelloWorld-0.0.1-SNAPSHOT/ (will no longer be accessible until 2016.3.9)
