vi locustfile\locustfile.py

from locust import TaskSet, task, between
from locust.contrib.fasthttp import FastHttpLocust

class WebsiteTasks(TaskSet):
    
    def on_start(self):
        pass

    def on_stop(self):
        pass

    @task
    def lua(self):
        with self.client.get('/lua', catch_response = True) as response:
            if response.status_code == 200:
                response.success()
            else:
                response.failure('Failed!')

class WebsiteUser(FastHttpLocust):

vi locust-slave.sh

#设置起多少个slave，建议根据CPU核数设置。该参数支持命令行传入，默认为1
SLAVE_COUNT=8

#配置MASTER-注意：由于每个slave都是一个独立的docker运行，所以这里千万不能配置127.0.0.1
MASTER_HOST="10.95.147.122"

我们打开两个终端，第一个启动master
./locust-master.sh
=> Starting locust
/usr/local/bin/locust -f /software/locust/locustfile/locustfile.py --master
[2019-12-13 17:00:06,957] a61084a0b533/INFO/locust.main: Starting web monitor at *:8089
[2019-12-13 17:00:06,958] a61084a0b533/INFO/locust.main: Starting Locust 0.13.2

第二个终端启动slave，并指定启动3个slave
/locust-slave.sh 3

此时观察master终端输出
