下面实例实现客户端浏览器请求指定网址，跳转到服务器Tomcat主页面。

所以需要参考上面去实现一些准备工作。

## 实现 ##

### 安装JDK ###

使用VmWare安装Ubuntu Server 16，然后安装JDK以及环境变量

参考下面：

#### 效果 ####

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70][]

### 安装Tomcat ###

下载Tomcat的tar包，自行去官网下载，这里是apache-tomcat-7.0.70.tar.gz

然后使用Xftp或者rz命令将Tomcat的tar包上传到 /usr/local 目录下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 1][]

然后将Tomcat的tar包解压

tar -xzvf apache-tomcat-7.0.70.tar.gz

x代表解压 z代表gz压缩 v显示解压列表 f解压文件名字

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 2][]

然后进入到解压的目录下的bin下的目录启动Tomcat

./startup.sh

#### 效果 ####

打开浏览器输入：

ip:8080

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 3][]

### 反向代理实现 ###

#### 流程 ####

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 4][]

客户端浏览器访问[www.badao.com][]，会映射到Nginx服务器上，然后通过反向代理去请求tomcat的主页面。

#### 配置域名映射ip ####

在C:\\Windows\\System32\\drivers\\etc下的host文件中配置映射

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 5][]

使用编辑器打开，添加ip与域名的映射

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 6][]

保存后，使用浏览器访问：

[www.badao.com:8080][www.badao.com_8080]

如果出现Tomcat的主页面则说明映射成功。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 7][]

虽然这样能直接通过8080端口直接访问，但是咱的目的是通过Nginx反向代理访问Tomcat的主页面，即通过80端口访问

而80端口又是默认端口，所以只需要域名就能访问Tomcat的主页面。

### 在Nginx进行反向代理的配置 ###

参考下面这篇文章，找到Nginx安装目录下的配置文件

Ubuntu Server 16.04 LTS上怎样安装下载安装Nginx并启动：

[https://blog.csdn.net/BADAO\_LIUMANG\_QIZHI/article/details/102828075][https_blog.csdn.net_BADAO_LIUMANG_QIZHI_article_details_102828075]

默认安装路径 /usr/local/nginx/conf/nginx.conf

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 8][]

然后编辑配置文件

vi nginx.conf

下面是默认的配置文件内容

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 9][]

下面要修改两个地方

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 10][]

然后保存。

并回到 /usr/local/nginx/sbin 下启动Nginx

./nginx

然后打开浏览器输入：

[www.badao.com][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 11][]
