大体思路
Nginx属于中间件，通过监听后端服务器应用，将页面转发给用户
安装Nginx
yum -y install nginx # 通过这种方式安装的Nginx，其根目录在/etc/nginx
启动Nginx服务
systemctl start nginx.service
此时访问服务器的80端口应该可以有界面显示了
修改nginx.conf文件
初始配置文件的如下框所示，我们需要添加Nginx需要监听的服务器端口，也就是Java应用所使用的端口。

稍作修改,在server内加入一个新的location
location /{ #配置访问的项目路径（注:这里重点） proxy_pass http://localhost:8080/; }
启动服务
重启nginx服务，然后启动java应用
systemctl restart nginx nohup java -jar jar包名
