Question

我有一个我在linux中创建的守护进程。我创建了init.d文件并使用

成功启动了守护进程

/etc/init.d/mydaemon start

当我试图阻止它（使用/etc/init.d/mydaemon停止）时，它会成功停止，但启动 - 停止 - 守护程序似乎永远不会完成，因为在调用启动后没有立即出现回声-stop-守护程序

详细模式显示它停止了该过程，并且查看系统监视器，它确实停止了该过程。

Stopped mydaemon (pid 13292 13310).

这是我的init.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"
}

我在虚拟机上运行它，这会影响到什么吗？

Answer 1

在虚拟机上运行不应该影响这一点我不知道为什么会发生这种情况或者它是如何接管父脚本的。

然而，我刚刚遇到这个问题并发现如果我这样做：

start-stop-daemon ...＆amp;＆amp; echo -n

它将按预期工作并放弃对shell的控制。

我不知道为什么会这样，但它似乎有效。

Linux守护进程停止start-stop-daemon
