Automatically deploy (publish, restart) Maven (Java) projects using shell scripts

Project structure such as

One: System environment

This machine: 10.4.18.3

Server: 10.4.18.4, user name: WEB02

Two: Initializing the server environment

Create a directory on the server's home directory Deploy,deploy/profile

Mkdir-p/home/web01/deploy

Mkdir-p/home/web02/deploy/profile

Installing the JDK

Export java_home=/home/web02/jdk1.7.0_67

Three: Source code (This shows a self-written HTTP web server)

Four: Precautions
1:pom.xml inside the/home/web02/deploy/profile/current/lib/need to be consistent with the server's publishing directory, or you will not find the jar
2:pom.xml inside the Profiles configuration usage, please refer to my previous blog

V: Usage
Go to the root directory of the project to execute
SH deploy.sh automatic deployment (post, restart) as prompted
After the publication is successful, enter in the browser
Http://10.4.18.4:17002/index
Http://10.4.18.4:17002/gson
You can see the results
