分布式启动

先启动 master (主机)：访问 http://localhost:8089/ 可查状态

locust -f car_city.py --master

再启动 slave (从机，--master-host 后面写主机 IP)

locust -f car_city.py --slave --master-host=192.168.89.126

启动从机后主机控制台会有连接上的日志

遇到的问题

在win10，从机启动后无法连接到主机（主机和从机不在同一台电脑），原因是主机的端口 5557 和 5558 没有加入到 入站规则，即该端口没开放别的机器无法访问（入站规则设置方法）
