一、输入子目录跳转
 
复制代码
location /templets {
        proxy_pass http://testServer/templets/;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
 
      location / {
        proxy_pass http://myServer;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
复制代码
当nginx主机输入 $host/templets 时会跳转进入
 
bb.bb.bb.bb:80;(可为其他web应用服务器ip)
复制代码
upstream myServer {
      #weigth参数表示权值，权值越高被分配到的几率越大
      #本机上的Squid开启3128端口
      server xx.xx.xx.xx:80;
    }
    upstream testServer {
      server bb.bb.bb.bb:80;
    }
复制代码
二、根据条件跳转
 
复制代码
 server {
      listen 80;
      server_name  www.xx.com;
      server_name  www.xx.com.cn;
      server_name  www.xx.net;
      server_name  www.xx.net.cn;
      if ( $host != 'www.xx.com' )  #如果用户输入的不是  https://www.xx.com 则转换成 https://www.xx.com/后缀 保证永远是 com 其他域名跳转到 .com  ssl只需要申请一个就行
      {
        rewrite ^(.*)$ https://www.xx.com$1  permanent;
      }
         location ~ ^/NginxStatus/ {
                        stub_status on;
                        access_log off;
         }      
       
 
      rewrite ^(.*)$  https://$host$1 permanent; # http 强制转 https  这个不可少少了有时会报错无法转换成 https 和上面的转换缺一不可
      ..............
      ..............
}
复制代码
 三、公司要求 news 二级目录跳转到另外一个 主机  但是 资源放在 当前主机二级目录 templets 下，而且当前主机配置ssl  所有http需要转成 https  ，而news 的目标主机是 http
 
配置如下：
 
复制代码
#设定负载均衡的服务器列表
upstream myServer {
#weigth参数表示权值，权值越高被分配到的几率越大
#本机上的apache开8080端口
server 127.0.0.1:8080;
# ip_hash;
}
upstream 3CMSServer {
server 目标ip:80;
}
 
 
server {
      listen 80;
      server_name  www.xxx.com;
      server_name  www.xxx.com.cn;
      server_name  www.xxx.net;
      server_name  www.xxx.net.cn;if ( $host != 'www.xxx.com' )
      {
        rewrite ^(.*)$ https://www.xxx.com$1  permanent; #强制域名
      }
  
      if ( $request_uri !~* '/news|/templets' )
        {
           rewrite ^(.*)$  https://$host$1 permanent; # http 强制转 https
        }
 
         location ~ ^/NginxStatus/ {
                        stub_status on;
                        access_log off;
         }      
       
      rewrite https://www.xxx.com/shouce.html  https://www.xxx.com/ permanent; # 这两个写的有错 强制转 http://www.xxx.com/shouce.html 到主页      
      rewrite https://www.xxx.net.cn/  https://www.xxx.com/ permanent;
 
      location / {     
      proxy_pass http://myServer/;
      proxy_redirect  off;
      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 50m;
      client_body_buffer_size 512k;
      proxy_connect_timeout 1024;
      proxy_send_timeout 960;
      proxy_read_timeout 900;
      proxy_buffer_size 128k;
      proxy_buffers 32 128k;
      proxy_busy_buffers_size 512k;  
      }
       
      location /news {
        proxy_pass http://3CMSServer/;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
      location /templets {
        proxy_pass http://3CMSServer/templets/;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      }
 
    }
