shell脚本-监控python进程是否在运行及启动python进程

shell脚本-监控python进程是否在运行，没有则重启jingdong_prices_run.py 并发送邮件告知重启时间,否则不重启不发送邮件

定时检测京东商品状态

shell监控python进程

# ps -ef 展示进程
# | grep your_keywords 按关键字筛选
# | grep -v “grep” 屏蔽grep程序本身的进程
# | awk ‘{print $2}’ 只打印第二列
# process_id=${语句} 将语句执行的返回值赋值给process_id，注意等号前后不能有空
# [ -z "$process_id”] 判断$process_id为空
# [[ -z "$process_id”]] 判断$process_id不为空 ， 注意这里前后有两个中括号，Shell的这个语法有点奇怪
# kill -9 $process_id 杀掉变量$process_id指定的进程

shell启动python进程

不需要手动 nohup python3 jing_app_run.py >/data/nohup.out/ 2>&1 & 启动,直接运行shell脚本
sh /data/scripts/spider-crawler.sh

#!/bin/bash
PROJECT=`basename $0 | awk -F '_' '{print $1}'`
APP_PATH="/data/app/$PROJECT"
APP_RUN_NAME=`ls $APP_PATH | grep py`
APP_PID=$(ps -ef | grep jing_app_run.py | grep -v grep | awk '{print $2}')
if [ -n "${APP_PID}" ]
then
kill -9 ${APP_PID}
sleep 5
fi
# 启动
cd ${APP_PATH}
nohup python3 ${APP_PATH}/${APP_RUN_NAME} > /data/logs/$PROJECT.out 2>&1 &
