参考文档:https://docs.locust.io/en/latest/quickstart.html

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
