【问题描述】:
我试图执行一个 bash 启动停止脚本,但是我得到了错误
nohup: 运行命令 `python2.7 失败
/home/shopStart.py': 没有这样的文件或目录
我正在尝试关注此帖子shell start / stop for python script,但已将启动命令更改为执行 python2.7
/home/shopStart.py
这是我的代码:
#!/bin/bash
script_home="/home"
script_name="$script_home/shopStart.py"
pid_file="$script_home/shoppid.pid"
# returns a boolean and optionally the pid
running() {
local status=false
if [[ -f $pid_file ]]; then
# check to see it corresponds to the running script
local pid=$(< "$pid_file")
local cmdline=/proc/$pid/cmdline
# you may need to adjust the regexp in the grep command
if [[ -f $cmdline ]] && grep -q "$script_name" $cmdline; then
status="true $pid"
fi
fi
echo $status
}
start() {
echo "starting $script_name"
nohup "python $script_name" &
echo $! > "$pid_file"
}
stop() {
# `kill -0 pid` returns successfully if the pid is running, but does not
# actually kill it.
kill -0 $1 && kill $1
rm "$pid_file"
echo "stopped"
}
read running pid < <(running)
case $1 in
start)
if $running; then
echo "$script_name is already running with PID $pid"
else
start
fi
;;
stop)
stop $pid
;;
restart)
stop $pid
start
;;
status)
if $running; then
echo "$script_name is running with PID $pid"
else
echo "$script_name is not running"
fi
;;
*) echo "usage: $0 <start|stop|restart|status>"
exit
;;
esac
【问题讨论】:
-
这似乎是文件位置的问题..你能在问题中显示文件系统上的文件位置吗?

@MohamedGad-Elrab 我接受了命令并在 ssh 会话中运行它,它运行良好。我还在脚本所在的文件夹中做了一个 pwd
