我有Nginx设置并正确显示测试页面.如果我尝试更改根路径,即使所有权限都相同,我也会收到403 Forbidden错误.此外,nginx用户存在.

nginx.conf:

user nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log;

pid        /run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    index   index.html index.htm;

    server {
        listen       80;
        server_name  localhost;
        root         /var/www/html; #changed from the default /usr/share/nginx/html
    }
}

namei -om /usr/share/nginx/html/index.html

f: /usr/share/nginx/html/index.html

drwxr-xr-x root root usr

我正在运行一个返回两列和X行的SQL查询.这两列是选择框的值和文本:

value: 1 text: Boston
value: 2 text: NYC
value: N text: Whatever

我想在查询完成时向结果集中添加另一行,以便我得到的结果如下:

value: 0 text: Select a city
value: 1 text: Boston
value: 2 text: NYC
value: N text: Whatever

我不想将新行添加到DB,只是添加到结果集.我想这样做的原因是CMS使用查询,我想避免入侵它.我见过一些涉及UNION或JOIN的解决方案,但我宁愿不将文本存储在别处.

这是我现在的问题:

SELECT id AS value, city AS text FROM #__cities

有什么相似的吗？

SELECT id AS value, city AS text FROM #__cities *APPEND id=0, formal_name='Select a city'*
