Explanation

Since many applications to achieve a rate letter separated front and rear ends, i.e., the interface layer and the business logic separated.
Business logic layer applications need to use tomcat, jar, etc. run, static pages using nginx proxy access.

Nginx and configurable cache access large static resources (e.g., a user avatar), to improve the response speed of the system.

- Configure proxy static resources
# 将静态资源放于/data/eim/www目录下
ll /data/eim/www/plist/eim.plist

# nginx配置代理/data/eim/www目录下的静态资源 vim /etc/nginx/conf.d/default.conf # 配置运行端口 listen 80; # 静态页面路径，将文件放于该目录下，即可被浏览器访问 location / { root /data/eim/www; # 错误页面路径 location = /50x.html { root /data/eim/www; :wq!
