nginx 配置 默认网站根目录（权限问题导致403 Forbidden错误的解决方法）

在安装 nginx 服务器后，我想把网站的根目录设置为 /root/www/ ，于是对 nginx 的 nginx.conf 文件进行配置

先打开 nginx.conf

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;
    
        charset utf-8;
    
        #access_log  logs/host.access.log  main;
    
        location / {
            root   /root/www/;          ## 设置的地方
            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   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;
            #}
        }
}

保存后，重启 nginx 服务，然后出现了 403 错误

网上查询后说是权限问题，更改 nginx.conf 的第一行
将 #user nobody; 改为 user root;

保存，再次重启 nginx 服务，访问成功

如果不想使用root用户运行，就不能把目录放在 /root/ 目录下了，可以选择放在 /home/www 下，并设置 www 的权限 777，同样可以访问成功。
