创建 aMule 守护进程 systemd .service 文件

创建 aMule 守护进程 systemd .service 文件

我最近搬到树莓派杰西在我的 RPi 上,现在我想将所有服务从 转移init.dsystemd.

aMule 守护进程现在正在与 init.d 一起使用,但我想将脚本移动到文件中amule-daemon.service,以添加来自其他服务的一些依赖项,例如autofs.

我的 aMule 实际 init.d 脚本是这样的:

#! /bin/sh
### BEGIN INIT INFO
# Provides:          amule-daemon
# Required-Start:    $local_fs $remote_fs
# Required-Stop:     $local_fs $remote_fs
# Should-Start:      $network
# Should-Stop:       $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Daemonized version of aMule.
# Description:       Starts the aMule daemon with the user specified in
#                    /etc/default/amule-daemon.
### END INIT INFO

SCRIPTNAME=/etc/init.d/$PKGNAME
WRAPPER=/usr/share/amule/amuled_home_wrapper.sh

[ -x "$DAEMON" ] || exit 0
[ -r /etc/default/$PKGNAME ] && . /etc/default/$PKGNAME

. /lib/init/vars.sh # has VERBOSE
. /lib/lsb/init-functions

if [ -z "$AMULED_USER" ]; then
    log_warning_msg \
    "Not starting $DESC, AMULED_USER not set in /etc/default/$PKGNAME."
    exit 0
fi

do_start()
{
    # Return
    #   0 if daemon has been started
    #   1 if daemon was already running
    #   2 if daemon could not be started
    start-stop-daemon --start --quiet --exec $DAEMON --user "$AMULED_USER" --chuid "$AMULED_USER" --test  >/dev/null || return 1
    start-stop-daemon --start --quiet --exec $WRAPPER --user "$AMULED_USER" --chuid "$AMULED_USER" >/dev/null || return 2
    start-stop-daemon --start --quiet --exec $WEB --user "$AMULED_USER" --chuid "$AMULED_USER" -- $WEB_OPTS & >/dev/null
}

do_stop()
{
    # Return
    #   0 if daemon has been stopped
    #   1 if daemon was already stopped
    #   2 if daemon could not be stopped
    start-stop-daemon --stop --quiet --retry="TERM/30/KILL/5" --exec $DAEMON --user "$AMULED_USER" --chuid "$AMULED_USER" 
    start-stop-daemon --stop --quiet --retry="TERM/30/KILL/5" --exec $WEB --user "$AMULED_USER" --chuid "$AMULED_USER"
    return "$?"
}


case "$1" in
  start)
    [ "$VERBOSE" != no ] && log_daemon_msg "Starting $DESC" "$PROGNAME"
    do_start
    case "$?" in
        0) [ "$VERBOSE" != no ] && log_end_msg 0 ;;
        1) [ "$VERBOSE" != no ] && \
            log_progress_msg "(already running)" && log_end_msg 0 ;;
        2) [ "$VERBOSE" != no ] && log_end_msg 1; exit 1 ;;
    esac
    ;;
  stop)
    [ "$VERBOSE" != no ] && log_daemon_msg "Stopping $DESC" "$PROGNAME"
    do_stop
    case "$?" in
        0 | 1) [ "$VERBOSE" != no ] && log_end_msg 0 ;;
        2)     [ "$VERBOSE" != no ] && log_end_msg 1; exit 1 ;;
    esac
    ;;
  restart|force-reload)
    log_daemon_msg "Restarting $DESC" "$PROGNAME"
    do_stop
    case "$?" in
      0 | 1)
        do_start
        case "$?" in
            0) log_end_msg 0 ;;
            1) log_end_msg 1; exit 1 ;; # Old process is still running
            *) log_end_msg 1; exit 1 ;; # Failed to start
        esac
        ;;
      *)
        # Failed to stop
        log_end_msg 1
        exit 1
        ;;
    esac
    ;;
  *)
    echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
    exit 3
    ;;
esac

exit 0

正如你所看到的,它被配置为启动 aMule 守护进程,并带有一些选项:

  • 以特定用户运行amuled
  • 运行网页界面amuleweb
  • 加载 Web 界面选项remote.conf
  • 使用设置主目录配置amuled_home_wrapper.sh

它工作完美。

如何将所有这些选项移至 .service 文件中?

我最终的工作解决方案是编写一个执行 init.d 脚本的 systemd 单元文件,无需转换整个脚本。

这是 aMule 的 systemd 单元。

[Unit]
Description=aMule Daemon
After=network.target
Requires=autofs.service

[Service]
User=amuled
Type=forking
ExecStart=/etc/init.d/amule-daemon start
ExecStop=/etc/init.d/amule-daemon stop
ExecReload=/etc/init.d/amule-daemon restart

[Install]
WantedBy=multi-user.target

注意:该Requires=autofs.service指令不是强制性的。它在那里是因为我用来autofs为配置为在其上读/写的服务挂载 NFS 驱动器。

在 debian/ubuntu 上,/etc/default/amule-daemon通过执行以下操作进行编辑sudo nano /etc/default/amule-daemon并放置AMULED_USER="user1"(如果您当前的用户是 user1)

然后只需重新启动守护进程:sudo systemctl restart amule-daemon.service
