這篇文章主要介紹“l(fā)inux下進程監(jiān)控的shell腳本分享”,在日常操作中,相信很多人在linux下進程監(jiān)控的shell腳本分享問題上存在疑惑,小編查閱了各式資料,整理出簡單好用的操作方法,希望對大家解答”linux下進程監(jiān)控的shell腳本分享”的疑惑有所幫助!接下來,請跟著小編一起來學習吧!
為確保php頁面在后臺運行,寫了一個監(jiān)控腳本,假設程序異常退出,那么可以自動重啟。
shell腳本/usr/local/scripts/receve.sh內容:
#!/bin/bash #funtion:keep receve.php running PHP="/usr/local/php5/bin/php" PROGRAM="receve.php" #start dameo $PHP /home/httpd/$PROGRAM >>/usr/local/scripts/phpshell/receve.out & chpid="$!"; echo "$chpid" > /usr/local/scripts/phpshell/receve.sid echo "child pid is $chpid" echo "status is $?" while [ 1 ] do wait $chpid exitstatus="$?" echo "child pid=$chpid is gone, $exitstatus" >>/usr/local/scripts/phpshell/receve.php_error.log echo `date` >> /usr/local/scripts/phpshell/receve.php_error.log echo "**************************" >>/usr/local/scripts/phpshell/receve.php_error.log sleep 10 $PHP /home/httpd/$PROGRAM >> /usr/local/scripts/phpshell/receve.out & chpid="$!"; echo "$chpid" > /usr/local/scripts/phpshell/receve.sid echo "next child pid is $chpid" echo "next status is $?" done
需要保證監(jiān)控腳本正常運行,在每天凌晨自動重啟腳本/usr/local/scripts/restart_r.sh,寫入crontab:
#!/bin/bash echo "" >/tmp/receve_pid.txt /bin/ps ax | /bin/grep "receve.sh" | /bin/grep -v "grep" | /bin/awk '{print $1}' >/tmp/receve_pid.txt no1pid=`cat /tmp/receve_pid.txt | sort -r` no2pid=`cat /usr/local/scripts/phpshell/receve.sid | sort -r` if [ -z $no1pid ];then echo "receve.sh pid is null, receve.sh is not running." else /bin/kill -9 "$no1pid" echo "receve.sh killed" fi sleep 3 if [ -z $no2pid ];then echo "receve.php pid is null, receve.php is not running." else /bin/kill -9 "$no2pid" echo "receve.php killed" fi rm -rf /usr/local/scripts/phpshell/receve.sid sleep 3 /usr/local/scripts/receve.sh > /dev/null &
crontab:
代碼如下:
#restart receve.sh
10 00 * * * /usr/local/scripts/restart_r.sh
注意:腳本命名要避免重復,避免自己kill掉自己的進程。
