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
