目录代理

  • web1作为前端端服务器，访问地址是 http://192.168.1.1 ，要将 http://192.168.1.1/bbs 的请求交给web2。在web1的网站根目录下并没有bbs目录

  • web1配置location 方式一

    1
    2
    3
    location /bbs/ {
        proxy_pass http://192.168.1.2/;     #有“/”
    }

  • web2作为后端web服务器，访问地址是 http://192.168.1.2

  • web1配置location 方式二 (location中不加 “/”)

    1

    3
    location /bbs/ {
        proxy_pass http://192.168.1.2;      #无“/”
