1.计算一下所有进程所占用内存大小的和。
#!/usr/bin/python
import os
list = []
sum = 0
str1 = os.popen('ps aux','r').readlines()
for i in str1:
str2 = i.split()
new_rss = str2[5]
list.append(new_rss)
for i in list[1:-1]:
num = int(i)
sum = sum + num
print '%s:%s' %(list[0],sum)
2.判断一个路径下是否是一个目录
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# @Time : 2018-12-18 15:16
# @Author : opsonly
# @Site :
# @File : opsUse.py
# @Software: PyCharm
import os
dir = "/var/www/html/EnjoyCarApi/"
if os.path.isdir(dir):
print('%s is a dir' % dir)
else:
print('%s is not a dir' % dir)
3.调取阿里云一个区域的所有ec2名称数据：
#!/usr/bin/env python
#coding=utf-8
import json
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkecs.request.v20140526.DescribeInstancesRequest import DescribeInstancesRequest
aliyun_user_ak = '************************' #API管理用户
aliyun_user_sk = '********************************' #API管理秘钥
region_id = 'cn-shenzhen'
client = AcsClient(ak=aliyun_user_ak, secret=aliyun_user_sk, region_id=region_id, timeout=300)
request = DescribeInstancesRequest()
request.set_accept_format('json')
response = client.do_action_with_exception(request)
res_dict = json.loads(response)
listarry = len(res_dict["Instances"]["Instance"])
# python2: print(response)
#print(str(response, encoding='utf-8'))
#print(res_dict["Instances"]["Instance"][0]["InstanceName"])
for i in range(0,listarry):
print('实例名称为：{} 实例ID为：{}'.format(res_dict["Instances"]["Instance"][i]["InstanceName"],res_dict["Instances"]["Instance"][i]["InstanceId"]))
4、修改阿里云服务器的实例名称：
#!/usr/bin/python3
#权限
aliyun_user_ak = '*************************' #API管理用户
aliyun_user_sk = '************************' #API管理秘钥
region_id = 'cn-hongkong' #区域名称
#填写
ecs_id = "i-***************" #服务器的实例ID
ecs_name = "******" #要修改的实例名称
#传入实例id，不存在返回1，存在则返回实例名称
def Get_EcsName(ecs_id):
import json
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkecs.request.v20140526.DescribeInstancesRequest import DescribeInstancesRequest
client = AcsClient(ak=aliyun_user_ak, secret=aliyun_user_sk, region_id=region_id, timeout=300)
request = DescribeInstancesRequest()
request.set_accept_format('json')
request.set_InstanceIds("[\"%s\"]" %(ecs_id))
response = client.do_action_with_exception(request)
res_dict = json.loads(response)
if res_dict["Instances"]["Instance"]:
return (res_dict["Instances"]["Instance"][0]["InstanceName"])
else:
return 1
#修改实例名称
def Modify_EcsName(ecs_name):
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkecs.request.v20140526.ModifyInstanceAttributeRequest import ModifyInstanceAttributeRequest
client = AcsClient(ak=aliyun_user_ak, secret=aliyun_user_sk, region_id=region_id, timeout=300)
request = ModifyInstanceAttributeRequest()
request.set_accept_format('json')
request.set_InstanceId("i-j6cf166lmefr8f6tdr4f") #这里也需要进行修改
request.set_InstanceName(ecs_name)
response = client.do_action_with_exception(request)
if __name__ == "__main__":
if Get_EcsName(ecs_id) == 1:
print("传入的ECS ID号不正确")
else:
Modify_EcsName(ecs_name)
if Get_EcsName(ecs_id) == ecs_name:
print("修改成功，实例" + ecs_id + "的最新实例名称为" + ecs_name)
else:
print("修改失败，请查看")
5.调取AWS控制台一个区域的实例基本信息
import boto3
access_key = "xxxxxxxxxxxxxxxx"
secret_key = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
client = boto3.client('ec2', aws_access_key_id=access_key, aws_secret_access_key=secret_key,region_name='ap-northeast-1')
ec2_regions = [region['RegionName'] for region in client.describe_regions()['Regions']]
for region in ec2_regions:
conn = boto3.resource('ec2', aws_access_key_id=access_key, aws_secret_access_key=secret_key,
region_name=region)
instances = conn.instances.filter()
for instance in instances:
if instance.state["Name"] == "running":
#print (region, instance.key_name, instance.public_dns_name, instance.image_id, instance.instance_type, instance.tags)
print ("AWS的实例区域是{}，实例公共DNS名称为{},秘钥名称为{}，实例类型为{}，实例标签为{}".format(region, instance.public_dns_name, instance.key_name, instance.instance_type, instance.tags))
print ('\n')
6.获取公司公网IP地址：
