nginx配置子域名跳转到后端请求

来源：互联网发布：凡人改串软件编辑：程序博客网时间：2024/06/09 19:42

项目情况简介：公司业务调整，新建子公司，专门做理财相关业务，对应需要分离出licai子站，但开发人员有限，最终定了主站和子站共用源代码和TOMCAT服务器，在NGINX上配置不同域名跳转到对应后端请求。

环境简介：全站https，两个SLB，一个SLB对应uat.mydomain.com，另外一个SLB对应子站的licai.mydomain.com。

服务器采用了NGINX做静态缓存和反向代理。新建子域名是直接配置DNS，指向对应的SLB.

对应的NGINX配置如下：

worker_processes  1;events {    use epoll;    worker_connections  1024;}http {    include       mime.types;    default_type  application/octet-stream;    log_format  uat.mydomain.com  '$remote_addr - $remote_user [$time_local] "$request" '                      '$status $body_bytes_sent "$http_referer" '                      '"$http_user_agent" "$http_x_forwarded_for"';    access_log  logs/access.log  uat.mydomain.com;    sendfile        on;    keepalive_timeout  600;    upstream uat.mydomain.com {         server 127.0.0.1:8080; #可以根据需要修改    }     upstream licai.mydomain.com {         server 127.0.0.1:8080; #可以根据需要修改    }     #用于共享文件    server {        listen       82;        server_name  localhost;        location / {            root   /mnt/attachments;            index  index.html index.htm;        }}      server {        listen      80;        server_name  uat.mydomain.com licai.mydomain.com;#80端口支持的域名        client_header_buffer_size 128k;        large_client_header_buffers 4 128k;#add_header Set-Cookie loginSessionHttp;        location / {            root   html;            index  index.html index.htm;        rewrite ^(.*) https://$host$1 permanent;#全站https            proxy_buffer_size 64k;            proxy_buffers   32 32k;            proxy_busy_buffers_size 128k;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_set_header X-Forwarded-Proto  $scheme;            client_max_body_size 50m;            proxy_connect_timeout 360;port_in_redirect off;real_ip_header X-Forwarded-For;        }        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }    }     server {        listen      443;        server_name  uat.mydomain.com;client_header_buffer_size 128k;        large_client_header_buffers 4 128k;add_header Set-Cookie loginSessionHttps;        location / {            root   html;            index  index.html index.htm;            proxy_buffers   32 32k;            proxy_busy_buffers_size 128k;            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_set_header X-Forwarded-Proto  $scheme;            client_max_body_size 50m;            proxy_connect_timeout 360;            port_in_redirect off;            real_ip_header X-Forwarded-For;             proxy_pass http://uat.mydomain.com/;         }error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }    }    server {        listen      445;        server_name  licai.mydomain.com;client_header_buffer_size 128k;        large_client_header_buffers 4 128k;add_header Set-Cookie loginSessionHttps;    port_in_redirect off; #防止跳转的时候带了端口号,会导致404    #映射图片和资源文件请求和主站一致    location ~ \.(css|js|gif|jpg|swf|png|htm|ico)$ {   proxy_pass http://licai.mydomain.com;        }#如下几条为了子站和主站公用后端代码location ~* /*financing* {            proxy_pass http://licai.mydomain.com;        }location ~* /*login/login* {            proxy_pass http://licai.mydomain.com;        }location ~* /*login/logout* {            proxy_pass http://licai.mydomain.com;        }location ~* /*userManage* {            proxy_pass http://licai.mydomain.com;        }location ~* /*sendSmsCode* {            proxy_pass http://licai.mydomain.com;        }#映射子域名到对应的后端请求        location / {            root   html;            index  index.html index.htm;            proxy_buffers   32 32k;            proxy_busy_buffers_size 128k;            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_set_header X-Forwarded-Proto  $scheme;            client_max_body_size 50m;            proxy_connect_timeout 360;            port_in_redirect off;            real_ip_header X-Forwarded-For;             proxy_pass http://licai.mydomain.com/financing/; #映射子域名到对应的后端请求         }error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }    }}
