Locust 使用(续更新)
本文以Centos 7为例
先对准系统时间：ntpdate ntp.aliyun.com
1、部署Python环境
Python3.6.5 下载
上传至操作系统,并解压
1371745-20220225112836645-465646129.png安装一些依赖包：
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel yum -y install zlib*
切到解压目录进行编译安装到/usr/local/python36下：
mkdir /usr/local/python36 -p ./configure --prefix=/usr/local/python36 --with-ssl make make install
安装完成之后，执行环境变量：
[[email protected] bin]# export PATH=/usr/local/python36/bin/:$PATH [[email protected] bin]# python3 -V Python 3.6.5 [[email protected] bin]# pip3 -V pip 9.0.3 from /usr/local/python36/lib/python3.6/site-packages (python 3.6)
至此，Python环境安装完成。
2、安装Locust
在目录下创建一个目录workspace
[[email protected] local]# pwd /usr/local [[email protected] local]# mkdir workspace
进入目录，创建虚拟空间：
[[email protected] local]# cd workspace/ [[email protected] workspace]# python3 -m venv ceshi
进入虚拟环境ceshi：
[[email protected] bin]# pwd /usr/local/workspace/ceshi/bin [[email protected] bin]# source activate (ceshi) [[email protected] bin]#
安装locust
(ceshi) [[email protected] bin]# pip install locust
安装完成后，新建一个discuz_index.py脚本，如下：
from locust import HttpUser, TaskSet, task
class UserBehavior(TaskSet):
@task(1)
def baidu(self):
self.client.get("/ip")
class Discuz_Locust(HttpUser):
tasks = [UserBehavior] #
host = "http://httpbin.org" //目标主机服务
min_wait = 1000
max_wait = 2000
[[email protected] ceshi]# pwd /usr/local/workspace/ceshi [[email protected] ceshi]# ll total 8 drwxr-xr-x. 2 root root 204 May 25 15:32 bin -rw-r--r--. 1 root root 303 May 25 15:33 discuz_index.py //赋予执行权限 chmod +x discuz_index.py drwxr-xr-x. 3 root root 18 May 25 15:32 include drwxr-xr-x. 3 root root 23 May 25 15:24 lib lrwxrwxrwx. 1 root root 3 May 25 15:24 lib64 -> lib -rw-r--r--. 1 root root 84 May 25 15:24 pyvenv.cfg [[email protected] ceshi]#
查看locust是否安装完成：

(ceshi) [[email protected] ceshi]# pwd /usr/local/workspace/ceshi (ceshi) [[email protected] ceshi]# ll total 12 drwxr-xr-x. 2 root root 218 May 25 15:42 bin -rwxrwxrwx. 1 root root 303 May 25 15:33 discuz_index.py drwxr-xr-x. 3 root root 18 May 25 15:32 include drwxr-xr-x. 3 root root 23 May 25 15:24 lib lrwxrwxrwx. 1 root root 3 May 25 15:24 lib64 -> lib -rw-r--r--. 1 root root 61 May 25 15:38 pip-selfcheck.json -rw-r--r--. 1 root root 84 May 25 15:24 pyvenv.cfg (ceshi) [[email protected] ceshi]# locust -f discuz_index.py
