一個好用的性能測試框架 locust

參考文檔：https://docs.locust.io/en/latest/quickstart.html

1、安裝
這個工具是用python寫的，首先我們要安裝框架

首先升級pip，不然可能會報錯
pip install --upgrade pip

然後安裝Locust
pip install Locust

安裝完成

2、編寫Locust file

這裏是壓測軟件的主要功能

vim locustfile.py

from locust import HttpLocust, TaskSet

#登陸操作
def login(l):
    l.client.post("/phpadmin/index.php", {"pma_username":"hugw", "pma_password":"redhat"})

#登出操作
def logout(l):
    l.client.post("/phpadmin/logout.php", {"db":"&", "token":"be2cb767a5829a398ef5a4c0dcafe504"})

#請求index
def index(l):
    l.client.get('/phpadmin/index.php')

class UserBehavior(TaskSet):
    tasks = {index}

#執行登陸和登出
    def on_start(self):
        login(self)

    def on_stop(self):
        logout(self)

class WebsiteUser(HttpLocust):
    task_set = UserBehavior
    min_wait = 3000
    max_wait = 6000

啓動壓測程序
如果配置文件名字是locustfile.py，那麼直接運行就好
啓動成功會監聽8089端口，
這裏的 http://192.168.1.9 是要壓測的網站域名

[root@slave locust]# locust -H http://192.168.1.9
[2018-04-12 19:41:37,086] slave/INFO/locust.main: Starting web monitor at *:8089
[2018-04-12 19:41:37,086] slave/INFO/locust.main: Starting Locust 0.8.1

配置壓測集羣（可選）

啓動壓測主程序，跟上面一樣，後面加上參數 --master
啓動成功會監聽8089端口，
這裏的 http://192.168.1.9 是要壓測的網站域名

[root@slave locust]# locust -H http://192.168.1.9 --master
[2018-04-12 22:20:12,889] slave/INFO/locust.main: Starting web monitor at *:8089
[2018-04-12 22:20:12,891] slave/INFO/locust.main: Starting Locust 0.8.1
[2018-04-12 22:20:47,669] slave/INFO/locust.runners: Client 'k8s_cf9d5e7c4238f74363180e5b3dcb0ae4' reported as ready. Currently 1 clients ready to swarm.
[2018-04-12 22:21:02,066] slave/INFO/locust.runners: Sending hatch jobs to 1 ready clients
[2018-04-12 22:21:12,069] slave/INFO/locust.runners: Resetting stats

啓動slave
先把 locustfile.py 分發到slave機器上，安裝locust，然後啓動

[root@k8s locust]# locust -H http://192.168.1.9 --slave --master-host=master_IP
[2018-04-12 02:21:48,045] k8s/INFO/locust.main: Starting Locust 0.8.1
[2018-04-12 02:22:02,487] k8s/INFO/locust.runners: Hatching and swarming 20 clients at the rate 2 clients/s...
[2018-04-12 02:22:12,509] k8s/INFO/locust.runners: All locusts hatched: WebsiteUser: 20
[2018-04-12 02:22:12,509] k8s/INFO/locust.runners: Resetting stats

然後登陸master壓測就行了

3、開始壓測

填寫你要模擬的用戶數量，這裏填500用戶，以每秒50數量增加，點擊start 開始
