在配置nginx 虚拟机时，执行
sudo /usr/sbin/nginx -t
报下面的错误：
nginx: [emerg] "root" directive is duplicate in /etc/nginx/server/blogs.conf:107 nginx: configuration file /etc/nginx/nginx.conf test failed
错误原因是：在配置文件时，访问路径设置了两个，重复配置webroot路径导致，去掉一个就可以了。
server { listen 80 default_server; #root /usr/share/nginx/html/;去掉这行 index index.html index.htm; # Make site accessible from http://localhost/ root /home/wangkongming/webroot/blogs; index index.html index.htm; server_name blogs.local; location / { try_files $uri $uri/ =404; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } access_log /data/logs/blogs/access.log; error_log /data/logs/blogs/error.log; }
