    windows

    https://www.apachelounge.com/download/

    CentOS下Yum直接安装:

    1. yum install httpd-tools

    Ubuntu下也差不多:

    1. apt-get install apache2-utils
    • -n参数用来设置模拟请求的总次数
    • -c参数用来设置模拟请求的并发数
    • -t参数用来设置模拟请求的时间

    ab -n 10000 -c 500 -t 10 http://192.168.0.91:9999/index.nginx-debian.html
