问题

RT
因为最近想学习一下Nginx服务器，就想搭建一个Tomcat+Nginx，简单的实现动静分离的功能。

具体代码和配置

版本

1. Ubuntu：ubuntu-16.04-desktop-amd64

2. JDK：jdk1.8.0_101

3. Tomcat：apache-tomcat-8.5.4

4. Nginx：nginx/1.10.0

5. ubuntu ip:192.168.182.129

Tomcat配置（/conf/server.xml）

Nginx 配置(/nginx/sites-available/default)

upstream tomcat {   
 server 192.168.182.129:8080;   
} 


server {
    listen 80 default_server;
    listen [::]:80 ;

    root /opt/apache-tomcat-8.5.4/webapps/springmvc;

    #server_name _;
    server_name test.nt.springmvc.com;

    location /{
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://tomcat;
        try_files $uri $uri/ =404;

    }
}

测试

1. 通过Tomcat，请求url：http://test.nt.springmvc.com:...

2. 通过Nginx，请求url：http://test.nt.springmvc.com/

3. 通过Nginx，请求url：http://test.nt.springmvc.com/...

4. 通过Nginx，请求url：http://test.nt.springmvc.com/...

通过日志可以看到，我第四次的请求并没有转发到Tomcat这里，找了网上好多文档，都没有发现是哪里出现的问题。下面是对应的网页

解决方法

Nginx 配置(/nginx/sites-available/default)

upstream tomcat {   
 server 192.168.182.129:8080;   
} 

server {
    listen 80 default_server;
    listen [::]:80 ;

    root /opt/apache-tomcat-8.5.4/webapps/springmvc;

    server_name test.nt.springmvc.com;

    location / {
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://tomcat;
        #try_files $uri $uri/ =404;
    }
}

可以看到在nginx的配置文件中，将try_files $uri $uri/ =404注解掉就可以正常访问了

try_files

nginx上try_files 判断文件是否存在

$uri

指的是请求的文件和路径，不包括“?”或者“#”之后的东西
$request_uri: /stat.php?id=1585378&web_id=1585378
$uri /stat.php
$document_uri: /stat.php
