Nginx系列6之-rewirte功能使用案例总结

使用案例1

网站架构如下:
公司部分服务器目前通过二级目录来调度到不同的服务器,如下所示:
image

按照上述需求,我们此时就配置了两个location,如下所示:

[root@localhost nginx]# vim /etc/nginx/conf.d/www-test.conf 
server {  
        listen       80;  
        server_name  xxx.com;
#        root   /home/nginx/test/mobile;  
        location / {
               proxy_pass http://127.0.0.1:8000/;
               proxy_set_header  Host $host;
               proxy_set_header  X-Real-IP  $remote_addr;
               proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
               client_max_body_size 100m;
               client_body_buffer_size 128k;
               proxy_connect_timeout 300;
               proxy_send_timeout 300;
               proxy_read_timeout 300;
               proxy_buffer_size 4k;
               proxy_buffers 4 32k;
               proxy_busy_buffers_size 64k;
               proxy_temp_file_write_size 64k;
               add_header X-Frame-Options SAMEORIGIN;
      }

        location /goa {
               proxy_pass http://127.0.0.1:8090/;
               proxy_set_header  Host $host;
               proxy_set_header  X-Real-IP  $remote_addr;
               proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
               client_max_body_size 100m;
               client_body_buffer_size 128k;
               proxy_connect_timeout 300;
               proxy_send_timeout 300;
               proxy_read_timeout 300;
               proxy_buffer_size 4k;
               proxy_buffers 4 32k;
               proxy_busy_buffers_size 64k;
               proxy_temp_file_write_size 64k;
               add_header X-Frame-Options SAMEORIGIN;
      }

访问xxx.com/goa的时候就出问题了,这个网站的所有js、images、css都加载不上了,因为css或者js是直接引用src='/css/xxx.css',此时nginx下面的location下面根本就没有css这个路径,尽管你通过goa来访问网站,但是引用的css、js路径是不会加上goa的,所以路径不会是/goa/css这样的,所以需要手工在src这个引用路径下添加goa这个目录。为了解决这样css、js无法应用的问题,那么就需要在nginx在做配置,使用rewrite功能,把访问/css的重写成/goa/css,/Scripts/改成/goa/Scripts。那么看下面的配置。

[root@localhost nginx]# vim /etc/nginx/nginx.conf
error_log  /var/log/nginx/error.log notice;    # 把日志级别调到notice,同时打开了rewrite日志的功能,方便更改rewrite功能
rewrite_log on;

[root@localhost nginx]# vim /etc/nginx/conf.d/www-test.conf 
server {  
        listen       80;  
        server_name  xxx.com;
#        root   /home/nginx/test/mobile;  
        location / {
               proxy_pass http://127.0.0.1:8000/;
               proxy_set_header  Host $host;
               proxy_set_header  X-Real-IP  $remote_addr;
               proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
               client_max_body_size 100m;
               client_body_buffer_size 128k;
               proxy_connect_timeout 300;
               proxy_send_timeout 300;
               proxy_read_timeout 300;
               proxy_buffer_size 4k;
               proxy_buffers 4 32k;
               proxy_busy_buffers_size 64k;
               proxy_temp_file_write_size 64k;
               add_header X-Frame-Options SAMEORIGIN;
      }

        location /goa {
               proxy_pass http://127.0.0.1:8090/;
               proxy_set_header  Host $host;
               proxy_set_header  X-Real-IP  $remote_addr;
               proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
               client_max_body_size 100m;
               client_body_buffer_size 128k;
               proxy_connect_timeout 300;
               proxy_send_timeout 300;
               proxy_read_timeout 300;
               proxy_buffer_size 4k;
               proxy_buffers 4 32k;
               proxy_busy_buffers_size 64k;
               proxy_temp_file_write_size 64k;
               add_header X-Frame-Options SAMEORIGIN;
      }

        location ~  ^(/css/|/Scripts/|/site/|/images/) {    # 新添的location
            if ($host = "xxx.com"){                 # 判断主机名是不是指定的域名
              rewrite  ^/css/(.*)   /goa/css/$1 last;   #  $1是指(.*)匹配的内容 ,last表示匹配到规则后重新发起一次请求。不能写break,break匹配完成后就此结束了,还是无法使用js、css等
              rewrite ^/site/(.*)    /goa/site/$1 last;
              rewrite ^/Scripts/(.*)   /goa/Scripts/$1 last;
              rewrite ^/images/(.*)   /goa/images/$1 last;
            }
        }
        
}

配置完成后,nginx -t 语法检测通过就可以重新reload使用了。
