我在本机部署了三个虚拟机，所有虚拟机都运行了相同的项目。三个虚拟机的地址分别为192.168.20.133:8080、192.168.20.135:8080和192.168.20.136:8080。其中，nginx服务器安装在133号虚拟机上，当前的负载均衡配置如下：

• 135号和136号虚拟机的权重均为2
• 133号虚拟机的权重为1

根据配置，访问时会按照135、136、135、136、133的顺序轮询访问，这只是一个典型的访问顺序，实际情况可能会有所不同。需要注意的是，如果136号虚拟机暂时停止运行，133号和135号虚拟机仍能继续提供服务，确保服务的稳定性。

关于静态文件的处理，nginx配置如下：

location ~.(gif|jpg|jpeg|png|css|js) {    root /usr/nginxStaticFile;    expires 2h;}

以下是完整的nginx配置文件内容：
