## 使用nginx来代理一个服务器下的不同项目 ##

**前言**：上一篇文章中，我实现了在同一tomcat下部署不同的项目，通过IP+指定端口可以访问到各自项目，那么新的需求来了：使用IP+端口太麻烦，而且这样的URL(例如作为扫码跳转地址时)在微信浏览器中，会出现这样的提示：

这样用户体验不好，敏感信息也多，如何通过域名，来访问这同一服务器下的一个tomcat中部署的两个项目，而且做到访问如丝般润滑呢？是时候祭出Nginx了

1.安装nginx:  
安装和配置途中也遇到不少的坑，具体的安装可以参考这篇文章，非常感谢这位博主：Linux下nginx的安装以及环境配置

2.配置域名  
安装好nginx之后，再来明确一下甲方需求：需要用不同的域名，来访问这一台服务器下，同一个tomcat中部署的两个项目，先在心中默念三遍，再开始配置：  
1.登陆阿里云，进入域名解析控制台，我现在有一个一级域名：weige.com,点击设置

点击添加记录，设置内容

配置信息

如此这般，我便配置好了第一个域名：jintian.weige.com---------->192.163.0.2(我的服务器地址)，如法炮制，第二个域名：mingtian.weige.com----->192.163.0.2(我的服务器地址)

3.修改nginx配置文件  
我配置好的nginx.conf文件：

    worker_processes  1;
    
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;

    }

nginx的默认端口是80，我们这里不做修改，我们解析的域名也默认访问的是80端口，这样，当使用域名请求服务器时，请求会先到达nginx,nginx根据不同的服务名，将请求转发到不同的项目，我的理解是这样，若有不对，欢迎吐槽。

4.重启nginx  
保存配置文件，重启nginx服务器,进入到安装路径下，我这里是：/usr/local/nginx/sbin，  
执行命令：./nginx  
查看进程：ps -ef |grep nginx，若出现类似提示，说明启动成功：
