In the realm of server administration, managing applications as services ensures their reliable operation and ease of control. For Java applications deployed on Linux systems, this article explores the options available to turn them into services and effectively manage their execution.
Starting and stopping a Java application on a Linux server often involves modifying the rc.local script. However, this approach lacks the ability to control the application independently and can be inconvenient for updates or troubleshooting.
To overcome these limitations, Linux systems provide the concept of services, managed through tools like init.d or systemd. These services allow you to start, stop, and restart applications at will, independent of server restarts.
Creating a Service for a Java Application
<code class="sh">#!/bin/sh SERVICE_NAME=WebServer PATH_TO_JAR=/path/to/WebServer.jar case in start) echo "Starting $SERVICE_NAME ..." nohup java -jar $PATH_TO_JAR & ;; stop) echo "Stopping $SERVICE_NAME ..." kill $(cat /tmp/WebServer-pid) rm /tmp/WebServer-pid ;; restart) <pre class="brush:php;toolbar:false"><code class="sh">chmod +x /usr/local/bin/WebServer</code>stop
<code class="sh">cp /usr/local/bin/WebServer /etc/init.d/WebServer ln -s /etc/init.d/WebServer /etc/rc?.d/S99WebServer</code>start ;; esac
<code class="sh">[Unit] Description=Web Server Service After=network.target [Service] Type=simple ExecStart=/usr/local/bin/WebServer start ExecStop=/usr/local/bin/WebServer stop Restart=on-failure StandardOutput=syslog StandardError=syslog [Install] WantedBy=multi-user.target</code>
Starting, Stopping, and Restarting the Service
To control the service, use the following commands:
Additional Features
By following these steps, you can effectively manage your Java applications as Linux services, gaining the flexibility and control to ensure their reliable operation and timely maintenance.
