(问题总结：

1.使用docker的nginx在配置vue 的dist包时与正常的路径不一样所以下面的路径要修改为：

location / {

#这个是docker中nginx的路径，因为我们是做的配置文件映射，所以我们这里面配置的地址都要基于docker中的真实路径
root /usr/share/nginx/html/dist;
try_files $uri $uri/ =404;
index index.html ;
}

2.集群部署时遇到了一个文件服务器的问题，因为当前项目文件的上传是与服务代码同体的，所以集群部署的话会出现无法下载文件的情况。

解：解决这个问题可以使用集群部署后台程序所在的服务器，实现磁盘共享，这样就可以实现文件的统一（可以在不同后台服务获取到公共的文件资源）

)

本次集群部署的方案：

1.为了提高信息集成平台的并发能力，

2.为了提高平台高可用性

集群方案：

https://www.cnblogs.com/royal6/p/12149852.html

实现记录：

（压力测试优化）

本次负载均衡的策略是：

ip_hash

指定负载均衡器按照基于客户端IP的分配方式，这个方法确保了相同的客户端的请求一直发送到相同的服务器，以保证session会话。这样每个访客都固定访问一个后端服务器，可以解决session不能跨服务器的问题。

（使用该策略可以水平服务并发处理的能力，并保证原有websocket长连接的正确使用）
