Nginx 配置虚拟主机1

Vps 上安装了 nginx。用多个子域名，每个子域名到不同的目录。

如：

http {
    server {
        listen 80;
        server_name a.chenlb.com;
        access_log logs/a.access.log main;

        server_name_in_redirect off;

        location / {
                index index.html;
                root /home/www/host_a/;
        }
    }

    server {
        listen 80;
        server_name b.chenlb.com;
        access_log logs/b.access.log main;

        server_name_in_redirect off;

        location / {
                index index.html;
                root /home/www/host_b/;
        }
    }
}

http {
    server {
        listen 80;
        server_name a.chenlb.com;
        access_log logs/a.access.log main;

        server_name_in_redirect off;

        location / {
                index index.html;
                root /home/www/host_a/;
        }
    }

    server {
        listen 80;
        server_name b.chenlb.com;
        access_log logs/b.access.log main;

        server_name_in_redirect off;

        location / {
                index index.html;
                root /home/www/host_b/;
        }
    }
}

结果发现用 b.chenlb.com 还是指到 host_a 目录。后来看了官方示例：http://wiki.nginx.org/NginxVirtualHostExample，提到有个 default 的匹配，如：

http {
  server {
    listen          80 default;
    server_name     _;
    access_log      logs/default.access.log main;

    server_name_in_redirect  off;

    location / {
      index index.html;
      root  /var/www/default/htdocs;
    }
  }
}

http {
  server {
    listen          80 default;
    server_name     _;
    access_log      logs/default.access.log main;

    server_name_in_redirect  off;

    location / {
      index index.html;
      root  /var/www/default/htdocs;
    }
  }
}

加上这个 default 就可使 a.chenlb.com 和 b.chenlb.com 正常工作了。
