問題

RT因為最近想學習一下Nginx服務器，就想搭建一個Tomcat+Nginx，簡單的實現動靜分離的功能。

具體代碼和配置版本

Ubuntu：ubuntu-16.04-desktop-amd64

JDK：jdk1.8.0_101

Tomcat：apache-tomcat-8.5.4

Nginx：nginx/1.10.0

ubuntu ip:192.168.182.129

Tomcat配置（/conf/server.xml）

通過Tomcat，請求url：http://test.nt.springmvc.com:...

通過Nginx，請求url：http://test.nt.springmvc.com/

通過Nginx，請求url：http://test.nt.springmvc.com/...

通過日志可以看到，我第四次的請求并沒有轉發到Tomcat這里，找了網上好多文檔，都沒有發現是哪里出現的問題。下面是對應的網頁

解決方法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_headerHost $host;proxy_set_headerX-Real-IP $remote_addr;proxy_set_headerX-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，將try_files $uri $uri/ =404注解掉就可以正常訪問了

try_files

nginx上try_files 判斷文件是否存在

$uri

指的是請求的文件和路徑，不包括“?”或者“#”之后的東西$request_uri: /stat.php?id=1585378&web_id=1585378$uri /stat.php$document_uri: /stat.php
