我有一个我在linux中创建的守护进程。我创建的init.d文件,并已成功地开始使用Linux守护进程停止启动 - 停止守护进程

/etc/init.d/mydaemon start 

当我试图阻止它(与/etc/init.d/mydaemon停止)的守护进程,但是,它成功地停止,但开始 - 停止守护进程似乎没有完成,因为在调用启动 - 停止守护进程之后没有立即发生回波,这一点证明了这一点。

详细模式显示它停止进程并查看系统监视器,它确实停止进程。

Stopped mydaemon (pid 13292 13310). 

这是我的stop.d文件的停止功能。

do_stop() 
{ 
    # Return 
    # 0 if daemon has been stopped 
    # 1 if daemon was already stopped 
    # 2 if daemon could not be stopped 
    # other if a failure occurred 
    start-stop-daemon --stop --name $NAME -v 
echo "stopped"#This is never printed and the script never formally gives shell back. 
    RETVAL="$?" 

    [ "$RETVAL" = 2 ] && return 2 

    # Wait for children to finish too if this is a daemon that forks 
    # and if the daemon is only ever run from this initscript. 
    # If the above conditions are not satisfied then add some other code 
    # that waits for the process to drop all resources that could be 
    # needed by services started subsequently. A last resort is to 
    # sleep for some time. 
    start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON 
    [ "$?" = 2 ] && return 2 
    # Many daemons don't delete their pidfiles when they exit. 

    return "$RETVAL" 
} 

我在虚拟机上运行这个,这会影响任何东西吗?

在虚拟机上运行不应该对此产生影响。
我不知道为什么会发生这种情况,或者它如何控制父脚本。

不过,我只是遇到了这个问题,并发现,如果我做的:

启动 - 停止 - 守护...... & &呼应-n

它将按预期工作和放弃控制壳。

我不知道为什么这个工程,但它似乎工作。
