Python实现检测服务器是否可以ping通的2种方法

#!/bin/bash
PING=`ping -c 3 $1 | grep '0 received' | wc -l`
echo $PING

#检查ip能否ping通
#0:正常，1：ping不通
def check_ip_ping():
    record = get_ip() #从数据库中读取的IP列表
    for i in range(0,len(record)):
        p = subprocess.Popen([r'./ping.sh',record[i]],stdout=subprocess.PIPE)
       result = p.stdout.read()
        Status = 0
        if result =='1\n':
            Status = 1
            #print i,record[i],'----ping failed----'
        else:
            ping_ok.append(record[i])
            #print i,record[i],'----ping success----'
        mysql('update ip_connect set Status=%d where IP="%s"'%(Status,record[i]))

#!/bin/bash
rm -f result.txt
cat ipmi_ping.txt | fping > result.txt

def check_online_ip():
    ip = mysql('select * from ip_check')

    #将IP写进一个文件
    if os.path.exists('iplist.txt'):
        os.remove('iplist.txt')
    iplist= 'iplist.txt'
    for i in range(0,len(ip)):
        with open(iplist, 'a') as f:
            f.write(ip[i][0]+'\n')

    #对文件中的IP进行fping
    p = subprocess.Popen(r'./fping.sh',stdout=subprocess.PIPE)
    p.stdout.read()

    #读result.txt文件，将IP is unreachable的行提取更新mysql状态为1
    result = open('result.txt','r')
    content = result.read().split('\n')
    for i in range(0,len(content)-1):
        tmp = content[i]
        ip = tmp[:tmp.index('is')-1]
        Status = 0
        if 'unreachable' in tmp:
            Status = 1
        #print i,ip
        mysql('update  ip_check set Status=%d where IP="%s"'%(Status,ip))
    print 'check all ipconnectness over!'
