本文实例讲述了Python实现获取nginx服务器ip及流量统计信息功能。分享给大家供大家参考，具体如下：

#!/usr/bin/python#coding=utf8log_file = "/usr/local/nginx/logs/access.log"with open(log_file) as f: contexts = f.readlines()# define ip dict###ip = {} # key为ip信息，value为ip数量（若重复则只增加数量）flow = {} # key为ip信息，value为流量总和sum = 0for line in contexts: # count row size of flow size = line.split()[9] # print ip ip_attr = line.split()[0] # count total size of flow sum = int(size) + sum if ip_attr in ip.keys(): # if ip repeated，如果ip重复就将ip数量加一，而流量继续叠加 # count of ip plus 1 ip[ip_attr] = ip[ip_attr] + 1 # size of flow plus size flow[ip_attr] = flow[ip_attr] + int(size) else: # if ip not repeated # define initial values of count of ip and size of flow ip[ip_attr] = 1 flow[ip_attr] = int(size)print(ip)print(flow)print(sum/1024/1024)

现在有nginx的访问日志：

利用python将nginx的ip进行统计

思路：将文件内容一行一行都出来，然后进行字符串strip().split()，得到一个列表，列表的第一个元素就是ip的内容

初始化一个空字典，用key表示ip内容，value表示该ip的个数，如果ip重复了，则将value进行增加：

[root@weblogic ~]# cat nginx.py #!/usr/bin/python#coding=utf8log_file = "/root/access.log"ip = {}with open(log_file) as f: for i in f.readlines(): print i.strip().split()[0] ip_attr = i.strip().split()[0] if ip_attr in ip.keys(): # 如果ip存在于字典中，则将该ip的value也就是个数进行增加 ip[ip_attr] = ip[ip_attr] + 1 else: ip[ip_attr] = 1print ip

获取执行结果：

[root@weblogic ~]# python nginx.py 192.168.223.1192.168.223.136192.168.223.1192.168.223.136192.168.223.1192.168.223.136192.168.223.1192.168.223.136192.168.223.1192.168.223.136{'192.168.223.1': 5, '192.168.223.136': 5}
