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。
