1、安装 这个工具是用Python写的,首先我们要安装框架
首先升级pip,不然可能会报错 pip install --upgrade pip
然后安装Locust pip install Locust
安装完成
2、编写Locust file
这里是压测软件的主要功能
vim locustfile.py
from locust import HttpLocust, TaskSet
#登陆操作 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"})
#请求index def index(l): l.client.get('/phpadmin/index.php')
class UserBehavior(TaskSet): tasks = {index}
#执行登陆和登出 def on_start(self): login(self)
def on_stop(self): logout(self)
class WebsiteUser(HttpLocust): task_set = UserBehavior min_wait = 3000 max_wait = 6000
启动压测程序 如果配置文件名字是locustfile.py,那么直接运行就好 启动成功会监听8089端口, 这里的 http://192.168.1.9 是要压测的网站域名
[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
配置压测集群(可选)
启动压测主程序,跟上面一样,后面加上参数 --master 启动成功会监听8089端口, 这里的 http://192.168.1.9 是要压测的网站域名
[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
启动slave 先把 locustfile.py 分发到slave机器上,安装locust,然后启动
[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
然后登陆master压测就行了
3、开始压测
填写你要模拟的用户数量,这里填500用户,以每秒50数量增加,点击start 开始
查看压测请求情况
