1、安装
这个工具是用Python写的，首先我们要安装框架
 
ASP站长网首先升级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

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
