memcached mysql nginx php redis

如题,最近在设计压力测试。
可以回答让某一项服务挂掉的方法,或者描述某一项服务挂掉的原理。

让PHP/Memcached/Redis挂掉比较难,需要一些hack技巧,常规情况下是不会挂的。
Nginx和MySQL就比较简单了,前者用类似ApacheBench一类的压测工具堆并发,处理不过来自然就502;后者就疯狂插插插,单表数据太大就炸了。

测试的目的不是为了让服务挂掉吧。
个人觉得正常是测试应该是用规范的方法,确保应用能满足需求。

既然测试者难以制造足以形成威胁的高并发,那就只有把这些服务相关进程的CPU和IO资源使用率摁下去了。

注:也可以把这些服务迁移到资源较低的计算机平台上运行,例如Raspberry Pi,谁用谁知道wwwwwww
