linux - Linux 中使用 systemd 的启动脚本

Question

请问下面这个启动服务，运行一次没有报错，但是下面的服务器脚本没有运行！

ln /lib/systemd/aquarium.service aquarium.service
systemctl daemon-reload
systemctl enable aquarium.service
systemctl start aquarium.service

谢谢

水族馆服务：

[Unit]
Description=Start aquarium server

[Service]
WorkingDirectory=/home/root/python/code/aquarium/
ExecStart=/bin/bash server.* start
KillMode=process

[Install]
WantedBy=multi-user.target

这是 server.sh 脚本

#!/bin/bash

PID=""

function get_pid {
   PID=`pidof python ./udpthread.py`
}

function stop {
   get_pid
   if [ -z $PID ]; then
      echo "server is not running."
      exit 1
   else
      echo -n "Stopping server.."
      kill -9 $PID
      sleep 1
      echo ".. Done."
   fi
}


function start {
   get_pid
   if [ -z $PID ]; then
      echo  "Starting server.."
      ./udpthread.py &
      get_pid
      echo "Done. PID=$PID"
   else
      echo "server is already running, PID=$PID"
   fi
}

function restart {
   echo  "Restarting server.."
   get_pid
   if [ -z $PID ]; then
      start
   else
      stop
      sleep 5
      start
   fi
}


function status {
   get_pid
   if [ -z  $PID ]; then
      echo "Server is not running."
      exit 1
   else
      echo "Server is running, PID=$PID"
   fi
}

case "$1" in
   start)
      start
   ;;
   stop)
      stop
   ;;
   restart)
      restart
   ;;
   status)
      status
   ;;
   *)
      echo "Usage: $0 {start|stop|restart|status}"

尝试使用“Type=forking”并使用完整的文件名。

[Unit]
Description=Start aquarium server

[Service]
WorkingDirectory=/home/root/python/code/aquarium/
Type=forking
ExecStart=/bin/bash server.sh start
KillMode=process

[Install]
WantedBy=multi-user.target

如果它不起作用，请发布此命令的输出：

# journalctl -u aquarium.service
