Nginx配置try_files实践二

1. 环境:

OS:Ubuntu 15.10

nginx:nginx/1.9.3 (Ubuntu)

假设有三台虚拟机db1(IP:192.168.68.21)/db2(IP:192.168.68.22)/db3(IP:192.168.68.23)，通过try_files等配置，使三台机器的/data/www/upload合集组成网络资源，并且支持HTTPS请求但SSL证书未认证。(注：未验证合法证书的场景)

设计思路如下：

Nginx配置try_files实践二

若请求到db2：

检索db2是否存在目标资源，若存在则返回，否则请求通过db1-proxy重定向到db1
检索db1是否存在目标资源，若存在则返回，否则返回404
把404重定向到db3
检索db3是否存在目标资源，若存在则返回，否则返回404
请求结束

若请求到db1/db3同理。

2. 配置三台机器nginx默认配置

略过具体过程，注意事项

配置日志格式
生成SSL证书并上传(/etc/nginx/server.crt, /etc/nginx/server.key)

3. 配置db1

/etc/nginx/conf.d/db1.test.com.conf

     server{

          listen ;

          server_name db1.test.com;

          listen  ssl;

          ssl on;

          ssl_certificate /etc/nginx/server.crt;

          ssl_certificate_key /etc/nginx/server.key;

          error_page  /.html;

        access_log  /var/log/nginx/db1_access.log  main;

        error_log   /var/log/nginx/db1_error.log;

        location  /upload

        {

         root /data/www;

         try_files $uri @db2;

        }

        location @db2{

         proxy_pass http://192.168.68.22:8000/proxy$uri;

         proxy_intercept_errors on;

         recursive_error_pages on;

         error_page  = @db3;

        }

        location @db3{

         proxy_pass http://192.168.68.23:8000/proxy$uri;

        }

     }

/etc/nginx/conf.d/db1-proxy.test.com.conf

     server{

          listen ;

          server_name db1-proxy.test.com;

          error_page  /.html;

        access_log  /var/log/nginx/db1_access.log  main;

        error_log   /var/log/nginx/db1_error.log;

        location  /proxy/upload

        {

         alias /data/www/upload;

        }

     }

重启nginx

4. 配置db2

/etc/nginx/conf.d/db2.test.com.conf

     server{

          listen ;

          server_name db2.test.com;

          listen  ssl;

          ssl on;

          ssl_certificate /etc/nginx/server.crt;

          ssl_certificate_key /etc/nginx/server.key;

          error_page  /.html;

        access_log  /var/log/nginx/db2_access.log  main;

        error_log   /var/log/nginx/db2_error.log;

        location  /upload

        {

         root /data/www;

         try_files $uri @db1;

        }

        location @db1{

         proxy_pass http://192.168.68.21:8000/proxy$uri;

         proxy_intercept_errors on;

         recursive_error_pages on;

         error_page  = @db3;

        }

        location @db3{

         proxy_pass http://192.168.68.23:8000/proxy$uri;

        }

     }

/etc/nginx/conf.d/db2-proxy.test.com.conf

     server{

          listen ;

          server_name db2-proxy.test.com;

          error_page  /.html;

        access_log  /var/log/nginx/db2_access.log  main;

        error_log   /var/log/nginx/db2_error.log;

        location  /proxy/upload

        {

         alias /data/www/upload;

        }

     }

重启nginx

5. 配置db3

/etc/nginx/conf.d/db3.test.com.conf

     server{

          listen ;

          server_name db3.test.com;

          listen  ssl;

          ssl on;

          ssl_certificate /etc/nginx/server.crt;

          ssl_certificate_key /etc/nginx/server.key;

          error_page  /.html;

        access_log  /var/log/nginx/db3_access.log  main;

        error_log   /var/log/nginx/db3_error.log;

        location  /upload

        {

         root /data/www;

         try_files $uri @db1;

        }

        location @db1{

         proxy_pass http://192.168.68.21:8000/proxy$uri;

         proxy_intercept_errors on;

         recursive_error_pages on;

         error_page  = @db2;

        }

        location @db2{

         proxy_pass http://192.168.68.22:8000/proxy$uri;

        }

     }

/etc/nginx/conf.d/db3-proxy.test.com.conf

     server{

          listen ;

          server_name db3-proxy.test.com;

          error_page  /.html;

        access_log  /var/log/nginx/db3_access.log  main;

        error_log   /var/log/nginx/db3_error.log;

        location  /proxy/upload

        {

         alias /data/www/upload;

        }

     }

重启nginx

6. 创建测试文件

server name	location	url
db1	/data/www/upload/db1.html	https://db1.test.com/upload/db1.html
db1	/data/www/upload/db1/test.html	https://db1.test.com/upload/db1/test.html
db2	/data/www/upload/db2.html	https://db2.test.com/upload/db2.html
db2	/data/www/upload/db2/test.html	https://db2.test.com/upload/db2/test.html
db3	/data/www/upload/db3.html	https://db3.test.com/upload/db3.html
db3	/data/www/upload/db3/test.html	https://db3.test.com/upload/db3/test.html

7. 配置本地host

192.168.68.21 db1.test.com

192.168.68.21 db1-proxy.test.com

192.168.68.22 db2.test.com

192.168.68.22 db2-proxy.test.com

192.168.68.23 db3.test.com

192.168.68.23 db3-proxy.test.com

8. 访问结果

url	http status
https://db3.test.com/upload/db1.html	200
