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=utf8
log_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 = 0
for 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=utf8
log_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] = 1
print ip
获取执行结果：
[root@weblogic ~]# python nginx.py
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
192.168.223.1
192.168.223.136
{'192.168.223.1': 5, '192.168.223.136': 5}
