shell腳本-監控python進程是否在運行及啟動python進程

shell腳本-監控python進程是否在運行，沒有則重啟jingdong_prices_run.py 並發送郵件告知重啟時間,否則不重啟不發送郵件

定時檢測京東商品狀態

# ps -ef 展示進程
# | grep your_keywords 按關鍵字篩選
# | grep -v “grep” 屏蔽grep程序本身的進程
# | awk ‘{print $2}’ 只打印第二列
# process_id=${語句} 將語句執行的返回值賦值給process_id，注意等號前后不能有空
# [ -z "$process_id”] 判斷$process_id為空
# [[ -z "$process_id”]] 判斷$process_id不為空 ， 注意這里前后有兩個中括號，Shell的這個語法有點奇怪
# kill -9 $process_id 殺掉變量$process_id指定的進程

shell啟動python進程

不需要手動 nohup python3 jing_app_run.py >/data/nohup.out/ 2>&1 & 啟動,直接運行shell腳本
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
# 啟動
cd ${APP_PATH}
nohup python3 ${APP_PATH}/${APP_RUN_NAME} > /data/logs/$PROJECT.out 2>&1 &
