折腾:

[记录]把服务器的IP地址映射到某二级域名http://hd.isip.cn

后来,把default.conf改为默认的内容:

➜  conf.d cat default.conf       
server {
    listen       80;
    server_name  localhost;
    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
    #error_page  404              /404.html;
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}
    # deny access to .htaccess files, if Apache’s document root
    # concurs with nginx’s one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

然后就可以正常访问了:

->

但是对于我之前的:

访问:

http://hd.webonn.com

会跳转到:

我的Flask的里面去处理

-》

之前的话,应该会提示用微信登陆:

最后,是用了,和之前类似的配置:

➜  conf.d pwd
/etc/nginx/conf.d
➜  conf.d cat default.conf
server {
    listen       80;
    server_name  localhost;
    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;
        location / {
        proxy_pass         http://127.0.0.1:8080/;
        #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;
        #proxy_set_header   X-Forwarded-Proto    $scheme;
    }
    #location / {
    #    root   /usr/share/nginx/html;
    #    index  index.html index.htm;
    #}
    #error_page  404              /404.html;
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}
    # deny access to .htaccess files, if Apache’s document root
    # concurs with nginx’s one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}
➜  conf.d

然后页面看可以访问了:

http://115.29.173.126

http://hd.webonn.com
