寫了個(gè)Python腳本監(jiān)控nginx進(jìn)程

接上一文 用iptables讓SSH服務(wù)對(duì)陌生人說(shuō)不 。還是有點(diǎn)擔(dān)心這個(gè)學(xué)期內(nèi)，nginx可能會(huì)因?yàn)橄到y(tǒng)各種原因而出現(xiàn)異常退出，導(dǎo)致Web服務(wù)暫停。所以，又來(lái)了一個(gè)方案。

view plain copy to clipboard print ?

1. #!/usr/bin/env?python ??
2. import ?os,?sys,?time??
3. ??
4. while ? True :??
5. ????time.sleep( 3 )??
6. ???? try :??
7. ????????ret?=?os.popen( 'ps?-C?nginx?-o?pid,cmd' ).readlines()??
8. ???????? if ?len(ret)?<? 2 :??
9. ???????????? print ? "nginx?process?killed,?restarting?service?in?3?seconds." ??
10. ????????????time.sleep( 3 )??
11. ????????????os.system( "service?nginx?restart" )??
12. ???? except :??
13. ???????? print ? "Error" ,?sys.exc_info()[ 1 ]??

      #!/usr/bin/env python
import os, sys, time

while True:
    time.sleep(3)
    try:
        ret = os.popen('ps -C nginx -o pid,cmd').readlines()
        if len(ret) < 2:
            print "nginx process killed, restarting service in 3 seconds."
            time.sleep(3)
            os.system("service nginx restart")
    except:
        print "Error", sys.exc_info()[1]

    

設(shè)置文件可執(zhí)行屬性，加入到/etc/rc.local，總算放心了。

這種方法還可以監(jiān)控別的進(jìn)程，我相信應(yīng)該有現(xiàn)成的監(jiān)控軟件，但是我覺得寫個(gè)腳本更方便。
