python & shell实现业务高峰期临时动态增加服务器
启停示例:
startInstance.py
#!/bin/env python3
# StartInstance
#coding=utf-8
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkecs.request.v20140526.StartInstanceRequest import StartInstanceRequest
import sys
id=sys.argv[1]
client = AcsClient('<accessKeyId>', '<accessSecret>', 'cn-hangzhou')
request = StartInstanceRequest()
request.set_accept_format('json')
request.set_InstanceId(id)
try:
response = client.do_action_with_exception(request)
print('StartInstance Exited Normally: ',str(response, encoding='utf-8'))
except Exception as e:
print('Exception occured: {}'.format(e))
sys.exit(5)

stopInstance.py
#!/bin/env python3
# StopInstance
#coding=utf-8
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException

print('StopInstance Exited Normally: ',str(response, encoding='utf-8'))
except Exception as e:
print('Exception ocurred: {}'.format(e))

操作SLB:
addBackendServer.py

from aliyunsdkcore.acs_exception.exceptions import ServerException

request = AddBackendServersRequest()
request.set_accept_format('json')
request.set_LoadBalancerId(slb)
request.set_BackendServers(
[{"ServerId": server, "Weight": "100", "Type": "ecs", "Port":"80","Description":"add-alternate-server" }]
)
try:
response = client.do_action_with_exception(request)
print('AddBackendServer Exited Normally',str(response, encoding='utf-8'))
except Exception as e:
print('Exception occured: {}'.format(e))
sys.exit(55)
removeBackendServer.py
#!/bin/env python3
#coding=utf-8
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkslb.request.v20140515.RemoveBackendServersRequest import RemoveBackendServersRequest
import sys
slb=sys.argv[1]
server=sys.argv[2]
client = AcsClient('<accessKeyId>', '<accessSecret>', 'cn-hangzhou')
request = RemoveBackendServersRequest()
request.set_accept_format('json')
request.set_BackendServers(
[{"ServerId":server}]
)
request.set_LoadBalancerId(slb)
try:
response = client.do_action_with_exception(request)
print('Remove Backend Server Exited Normally:',str(response, encoding='utf-8'))
except Exception as e:
print('Exception occured: {}'.format(e))
sys.exit(88)
调整权重
#!/bin/env python3
#coding=utf-8
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkslb.request.v20140515.SetBackendServersRequest import SetBackendServersRequest
import sys
slb_id=sys.argv[1]
id=sys.argv[2]
weight=sys.argv[3]
#配置阿里云子账号的SLB管理账号密码
client = AcsClient('<accessKeyId>', '<accessSecret>', 'cn-hangzhou')
#给变量赋值
request = SetBackendServersRequest()
request.set_accept_format('json')
#设置需要修改的ecs权重
request.set_BackendServers([
{"ServerId":id,"Weight":weight}
])
#指定负载均衡器
request.set_LoadBalancerId(slb_id)
#发起请求执行slb操作
response = client.do_action_with_exception(request)
#打印结果
print(str(response, encoding='utf-8'))
