Nginx配置try_files实践二

本文内容承接《Nginx配置try_files实践一》
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：
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 |
| /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 |
| /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 |
| /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 |
| http://db3.test.com/upload/db1.html | 200 |
| https://db3.test.com/upload/db1/test.html | 200 |
| http://db3.test.com/upload/db1/test.html | 200 |
| https://db3.test.com/upload/db2.html | 200 |
| http://db3.test.com/upload/db2.html | 200 |
| https://db3.test.com/upload/db2/test.html | 200 |
| http://db3.test.com/upload/db2/test.html | 200 |
| https://db3.test.com/upload/db3.html | 200 |
| http://db3.test.com/upload/db3.html | 200 |
| https://db3.test.com/upload/db3/test.html | 200 |
| http://db3.test.com/upload/db3/test.html | 200 |
| https://db3.test.com/upload/db3/test1.html | 404 |
| http://db3.test.com/upload/db3/test1.html | 404 |
| https://db3.test.com/upload/dbfdsafas | 404 |
| http://db3.test.com/upload/dbfdsafas | 404 |
