Linux 启动时启动 java 程序(EC2 实例) [英] Linux Launch java program on startup (EC2 instance)

问题描述

我的服务器程序需要在 EC2 实例启动时启动.此刻，我只是使用以下命令从我的 SSH 启动它:

my server program needs to be launched on the startup of an EC2 instance. At the minute im just launching it from my SSH with the following commands:

 java -jar ~/DocumentManager/DocumentServer-0.2.jar  

我尝试将其添加到 .bashrc 和/etc/rc.local 文件中，但它们似乎只在我通过 ssh 进入时才起作用.

I tried adding this to the .bashrc and /etc/rc.local files but they only seem to work when i ssh in.

有人知道如何在计算机启动时启动我的应用程序实例吗?

Anyone know how to make it so an instance of my application is launched when the computer boots?

谢谢，

本

推荐答案

你可以像这样创建一个 java_server_launch.sh 脚本:

It's possible you can create a script java_server_launch.sh like this:

 #! /usr/bin/sh

    PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
    JAVA=/usr/bin/java
    MY_SERVER=/home/your_username/DocumentManager/DocumentServer-0.2.jar
    USER=your_username
    /bin/su - $USER -c "$JAVA -jar $MY_SERVER &"

把你的脚本放在/etc/init.d目录下，然后使用命令:

Put your script under /etc/init.d directory, and then use the command:

update-rc.d java_server_launch.sh defaults

更多关于 update-rc.d 命令的信息，请使用 man update-rc.d.

more on update-rc.d command by using man update-rc.d.
