linux检测服务宕机自动重启

一：创建启动脚本 course-reload.sh

二：脚本内容，10检测一次

while : 
do
run=$(ps -ef | grep course-service.jar | grep -v grep)
if [ "$run" ] ; then
echo "运行中!" 
else
echo "已停止，正在重启!" 
sudo systemctl start course &
echo "重启成功!" 
fi
sleep 10
done

三：授权

# 1.授权
chmod 777 course-reload.sh
# 2.处理脚本无法运行异常：报错syntax error near unexpected token `$'\r''解决方法
sed -i 's/\r//g' course-reload.sh

四：启动并打印日志

nohup ./course-reload.sh > courseLog.txt &
