通过crontab调度UpStart init脚本

标签: linux shell ubuntu crontab upstart

我在ProcessRunner.conf Ubuntu中创建了以下/etc/init/

# When to start the service
start on runlevel [2345]

# When to stop the service
stop on runlevel [016]

# Automatically restart process if crashed
respawn

# Essentially lets upstart know the process will detach itself to the background
expect fork

# Run before process
pre-start script
    [ -d /var/run/ProcessRunner ] || mkdir -p /var/run/ProcessRunner
    java -Dlog4j.configuration=log4j_process1.xml -classpath /home/devuser/apps/ProcessExecutor:/home/devuser/apps/ProcessExecutor/ProcessExecutor-1.0.jar com.process.ApplicationStartup &
    echo $! > /var/run/ProcessRunner/ProcessRunner.pid;
end script

post-stop script
     processid=$(cat /var/run/ProcessRunner/ProcessRunner.pid);
     if ps -p $processid > /dev/null
        then
        sudo kill -9 $processid;
     fi;
end script

我使用以下命令从命令行启动/停止此操作:

sudo start ProcessRunner
sudo stop ProcessRunner

工作正常。现在我需要安排这些。我这样做:

我使用以下命令从命令行启动/停止此操作:

$sudo crontab -e

0 0 * * * * start ProcessRunner
0 2 * * * * stop ProcessRunner

但这不起作用。请帮忙。 另外,我不希望这个过程在系统启动时开始。我该如何配置?

Crontab环境不提供路径,因此命令(启动ProcessRunner)必须包含完整路径。

命令的完整路径"开始"并且"停止",而不是你的新贵配置文件!

因此,基本上,您的crontab应如下所示:

0 0 * * * * /sbin/start ProcessRunner
0 2 * * * * /sbin/stop ProcessRunner
