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。
二选一的问题
