systemctl 控制程序开机自启动

直接使用/etc/init.d/libraryclient start 可以成功启动程序
我在 /etc/systemd/system/ 路径下加入了我的文件，调用启动后查看后台日志发现：程序调用启动后立即调用停止命令，不知道为什么？

system代码：

[Service]
#Type=forking
Type=simple
ExecStart=/etc/init.d/libraryclient start
ExecStop=/etc/init.d/libraryclient stop
ExecReload=/etc/init.d/libraryclient restart
Restart=always

启动脚本代码

set -x
P=8000
worker=2
host="0.0.0.0"
export PATH=$PATH:/usr/local/python3/bin
cd /web/LibraryManClient
echo "$@"
case "$@" in
    start)
        gunicorn -b $host:$P -w $worker LibraryManClient.wsgi:application -D
        ;;
    restart)
        kill -9 `ps aux|grep gunicorn|grep $P|awk '{print $2}'|xargs`
        sleep 1
        gunicorn -b $host:$P -w $worker LibraryManClient.wsgi:application -D
        ;;
    stop)
        kill -9 `ps aux|grep gunicorn|grep $P|awk '{print $2}'|xargs`
        ;;
esac

执行：systemctl start 程序之后
查看：journalctl -f | grep libraryclient

踩坑：
尝试将forking改成默认的simple，没有作用
将system中的文件的 stop和reload 注释掉，journalctl -f | grep libraryclient 没有了stop 但是依然无法启动

希望：
可以使用systemctl start 命令启动服务

使用systemctl ，是systemd的服务
而你写的脚本是基于systemV的，根本不是一回事
你只需要在/etc/systemd/system下建立一个.service文件
