## Nginx

**理论教学**
</div>

> 配置`Nginx`的反向代理，项目上有多台服务器`80`端口等都被占用了，`tomcat`启动不起来，都需要一台`Nginx`代理出去。使用`Nginx+Tomcat`实现此项目的反向代理，至于`Nginx，tomcat`如何搭建百度一大把。请自己百度下。此案例是在一台服务器上面实现，一台虚拟机安装了两个`tomcat`使用不同的端口。

&nbsp;

## 虚拟机环境

- 服务器ip：192.168.161.189
- Nginx端口：80
- Tomcat1端口：8070
- Tomcat2端口：8080
  一台服务器安装了两个`Tomcat`使用不同端口实现代理

&nbsp;

## 配置反向代理

**1**、编辑配置文件`vim Nginx.conf` 在`server`段里面的`location`加上`proxy_pass  http://ip:端口` 、添加完成后保存，并重启`nginx`
重启命令`/etc/init.d/nginx -s reload `

![新增反向代理配置](https://img-1259793745.itggg.cn/20201222203334.png)

&nbsp;
**2**、使用浏览器进行访问代理的地址，不加端口，简单的反向代理已经完成

&nbsp;

## 配置多个代理

编辑`vim Nginx.conf`
配置多个反向代理实现方式，是通过不同的端口代理访问。复制一个`server`段，将两个`server`段`nginx`的端口更改，使用`nginx`的不同端口访问。
<div class="tip inlineBlock warning">

第一个server段配置tomcat1（192.168.161.189：8070）
</div>

![第一个](https://img-1259793745.itggg.cn/20201222203336.png)

第二个server段配置（192.168.161.189：8080）
</div>

![第二个](https://img-1259793745.itggg.cn/20201222203337.png)

配置完成后，重启`nginx`

&nbsp;
**1**、先访问`nginx`代理的第一个`tomcat1`

![访问正常](https://img-1259793745.itggg.cn/20201222203338.jpg)

&nbsp;
**2**、访问`nginx`代理的第二个`tomcat2`

![访问正常](https://img-1259793745.itggg.cn/20201222203339.jpg)

以上就是通过`nginx`的不同端口代理多个地址，若还要代理更多通过`nginx`的不同端口，增加`server`段就行。
