本文中,我们介绍Nginx如何做端口转发,还有各种转发规则
首先介绍最常用的,将域名转发到本地另一个端口上
server{ listen 80; server_name tomcat.shaochenfeng.com; index index.php index.html index.htm; location / { proxy_pass http://127.0.0.1:8080; # 转发规则 proxy_set_header Host $proxy_host; # 修改转发请求头,让8080端口的应用可以受到真实的请求 proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }
这样访问 http://tomcat.shaochenfeng.com 时就会转发到本地的 8080 端口
server{ listen 80; server_name baidu.shaochenfeng.com; index index.php index.html index.htm; location / { proxy_pass http://www.baidu.com; proxy_set_header Host $proxy_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }
这样访问 http://baidu.shaochenfeng.com 时就会转发到 http://www.baidu.com
server{ listen 80; server_name 127.0.0.1; # 公网ip index index.php index.html index.htm; location / { proxy_pass http://127.0.0.1:8080; # 或 http://www.baidu.com proxy_set_header Host $proxy_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } }
这样访问 http://127.0.0.1 时就会转发到本地的 8080 端口或 http://www.baidu.com
在配置proxy_pass代理转发时,如果后面的url加/,表示绝对根路径;如果没有/,表示相对路径
例如
server_name shaochenfeng.com location /data/ { proxy_pass http://127.0.0.1/; }
访问 http://shaochenfeng.com/data/index.html 会转发到 http://127.0.0.1/index.html
server_name shaochenfeng.com location /data/ { proxy_pass http://127.0.0.1; }
访问 http://shaochenfeng.com/data/index.html 会转发到 http://127.0.0.1/data/index.ht
