现在我正在使用此脚本重新启动我的进程：
#!/usr/bin/env bash
set -u
set -e
set -x
#
# const define area
#
PROGRAM_NAME="schedulespider.py"
CELERY_PROGRAM_NAME="celery"
PYTHON_BIN_PATH="/usr/bin/python3"
#
# stop celery process
#
ps auxww | grep celery | awk '{print $2}' | xargs kill -9
sleep 5s
ps auxww | grep schedulespider | awk '{print $2}' | xargs kill -9
#
# stop python process
#
sleep 5s
#
# start process
#
count=`ps -ef | grep ${PROGRAM_NAME} | grep -v "grep" | wc -l`
if [[ ${count} -lt 1 ]]; then
# /usr/bin/python3 -m pip install --upgrade pip
# pip3 install -r requirements.txt
export PYTHONIOENCODING=utf-8
nohup ${PYTHON_BIN_PATH} schedulespider.py > /dev/null &

sleep 3
else
echo "unable to start app, process already exists!"
fi
该脚本杀死了旧进程并启动一个新进程。但是当我在 GitHub Actions 中远程执行脚本时，显示如下日志：
cd /opt/apps/pydolphin

最后脚本超时了！！！为什么脚本没有自动退出？我已经在后台进行了该过程。我应该怎么做才能避免这个问题？
答案1
我有一个类似的问题。通过将输入发送到 dev\null 以及输出来修复它。在你的情况下：
nohup ${PYTHON_BIN_PATH} schedulespider.py < /dev/null & > /dev/null &
