bash – 将shell脚本放在systemd控件下

#!/bin/sh
# cherrypy_server.sh

PROCESSES=10
THREADS=1 # threads per process
BASE_PORT=3035 # the first port used
# you need to make the PIDFILE dir and insure it has the right permissions
PIDFILE="/var/run/cherrypy/myproject.pid"
WORKDIR=`dirname "$0"`
cd "$WORKDIR"

cp_start_proc()
{
 N=$1
 P=$(( $BASE_PORT + $N - 1 ))
 ./manage.py runcpserver daemonize=1 port=$P pidfile="$PIDFILE-$N" threads=$THREADS request_queue_size=0 verbose=0
}

cp_start()
{
 for N in `seq 1 $PROCESSES`; do
  cp_start_proc $N
 done
}

cp_stop_proc()
{
 N=$1
 #[ -f "$PIDFILE-$N" ] && kill `cat "$PIDFILE-$N"`
 [ -f "$PIDFILE-$N" ] && ./manage.py runcpserver pidfile="$PIDFILE-$N" stop
 rm -f "$PIDFILE-$N"
}

cp_stop()
{
 for N in `seq 1 $PROCESSES`; do
  cp_stop_proc $N
 done
}

cp_restart_proc()
{
 N=$1
 cp_stop_proc $N
 #sleep 1
 cp_start_proc $N
}

cp_restart()
{
 for N in `seq 1 $PROCESSES`; do
  cp_restart_proc $N
 done
}

case "$1" in
 "start")
  cp_start
 ;;
 "stop")
  cp_stop
 ;;
 "restart")
  cp_restart
 ;;
 *)
  "$@"
 ;;
esac

从bash脚本中,我们基本上可以做三件事：

>通过调用./cherrypy_server.sh start启动cherrypy服务器
>通过调用./cherrypy_server.sh stop来停止cherrypy服务器
>通过调用./cherrypy_server.sh restart重新启动cherrypy服务器

我如何将这个shell脚本置于systemd的控制之下作为cherrypy.service文件(显然的目标是让systemd在重启机器时启动cherrypy服务器)？

这里参考systemd服务文件示例 – https://wiki.archlinux.org/index.php/Systemd#Using_service_file
