java - 如何在 AIX 中将 jar 文件作为服务运行，以便在崩溃时自动重新启动？

Question

我有几个 jar 文件，我想将它们作为服务在 AIX 上运行。如果服务崩溃/结束，则必须自动重新启动。我怎样才能实现这个目标？

我有一个像这样的 shell 脚本

(
    until java -jar Test.jar; do
        echo "Test Service crashed with exit code $?.  Respawning... " >&2
        sleep 5
    done
) 

这可行，但我想知道是否有更好的方法来做到这一点？如果机器由于某种原因重新启动，则必须手动运行该脚本。我不是 Linux 或 AIX 方面的专家。

inittab entries

Let’s look at a entry for inittab that runs a script. Suppose, we want to run a script that sends an email to system administrators stating that the box is available when the system come up.

The entry for inittab is shown below:

mailout:2:once:/usr/local/bin/mailout > / dev/null 2>&1 #mail users

The above entry can be summarized as follows:

mailout: The unique identifier

2: Run this when the system reaches runlevel two (the default) once: Run the script and do not wait for its termination; init will carry on processing inittab. Iif the process fails, init will not attempt to rerun it. /usr/local/bin/mailout: The full path and script name of the command to run; notice that the output is thrown away to /dev/dull. We end with a ‘#’ comment on what the script does.

For completeness, here is the script in question:

!/bin/sh                                                    
#mailout                                                    
/usr/sbin/sendmail ‑t <<mayday                              
From: hostname                                              
To: rs6admins                                               
Subject: hostname P‑Series is up                            
The AIX hostname is now up, please check services.          
.
